[SOLVED] Calling header files between sofa plugins

[bgarcial]

Hi Sofa People

Currently, I have two plugins such as follow:

/applications/plugins/SerialCommunication
/applications/plugins/ZMQCommunication

We need to use some SerialCommunication classes from ZMQCommunication plugin

In SerialCommunication, we have the following in the SerialDriver.h:

namespace sofa
{
namespace simulation { class Node; }

namespace component
{
namespace visualModel { class OglModel; }

namespace controller
{
class SerialDriver : public sofa::core::objectmodel::BaseObject
{
private:
    float posDOFEST;
    void handleEvent(core::objectmodel::Event *);
    bool noDevice;

    //Serial Functions
    int  serial_open(char *serial_name, speed_t baud);
    void serial_send(int serial_fd, char *data, int size);
    int  serial_read(int serial_fd, char *data, int size, int timeout_usec);
    void serial_close(int fd);
};
}
}
}

From ZMQCommunication plugin we want import and use the SerialDriver class methods and we try use the respective namespaces such as following:

#include <../SerialCommunication/SerialDriver.h>
using sofa::component::controller;
SerialDriver serial;

And this does not work and we get an error which says:

In file included from /home/asanchez/Universidad/Investigación/Christian/SimDesign2/src/applications/plugins/ZeroMQCommunication/ZMQServerComponent.cpp:7:0:
/home/asanchez/Universidad/Investigación/Christian/SimDesign2/src/applications/plugins/ZeroMQCommunication/ZMQServerComponent.h:5:49: fatal error: ../SerialCommunication/SerialDriver.h: No such file or directory
 <strong>#include <../SerialCommunication/SerialDriver.h></strong>

In addition, we get these other errors:

applications/plugins/ZeroMQCommunication/ZMQServerComponent.cpp: In member function ‘void sofa::component::controller::ZMQServerComponent::instrumentDataSend(sofa::component::controller::instrumentData)’:
/home/asanchez/Universidad/Investigación/Christian/SimDesign2/src/applications/plugins/ZeroMQCommunication/ZMQServerComponent.cpp:49:5: error: ‘SerialDriver’ was not declared in this scope
     SerialDriver serial;

How can I instance the SerialCommunication classes from ZMQCommunication classes to be used?

We are using Fedora 24 x64

Hi bgarcial,

Using components from another plugin is very similar to using components from a SOFA module. I think you missed the CMake part.

Here are the main steps :
1. Create your plugin’s CMake variables: find_package(SerialCommunication)
2. Get access to your plugin files: target_include_directories(${PROJECT_NAME} PUBLIC "$<BUILD_INTERFACE:${SerialCommunication_INCLUDE_DIRS}>")
3. Link with your plugin: target_link_libraries(${PROJECT_NAME} SerialCommunication)

An example is available in applications/plugins/image. See how it includes CImgPlugin.

Hope that helps,
Guillaume.

[bgarcial]

Hi Guillaume,

In first instance thanks for their answering

I followed the steps that you described above, in the CMakeList.txt of ZMQCommunication plugin I Include following things.

1. Create your plugin’s CMake variables: find_package(SerialCommunication)
2. Get access to your plugin files: target_include_directories(${PROJECT_NAME} PUBLIC "$<BUILD_INTERFACE:${SerialCommunication_INCLUDE_DIRS}>")
3. Link with your plugin: target_link_libraries(${PROJECT_NAME} SerialCommunication)

But When I compiled I got the next error:

Adding Plugin ZeroMQCommunication
CMake Error at applications/plugins/ZeroMQCommunication/CMakeLists.txt:23 (find_package):
  By not providing "FindSerialComunication.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "SerialComunication", but CMake did not find one.

  Could not find a package configuration file provided by
  "SerialComunication" with any of the following names:

    SerialComunicationConfig.cmake
    serialcomunication-config.cmake

  Add the installation prefix of "SerialComunication" to CMAKE_PREFIX_PATH or
  set "SerialComunication_DIR" to a directory containing one of the above files.  If "SerialComunication" provides a separate development package or
  SDK, be sure it has been installed.

What can I do? I tried to create SerialComunicationConfig.cmake and I can’t solve that problem

I really would appreciate the support that you can give me.

[Guillaume]

Hi,

Every SOFA plugin has to generate a MyPluginConfig.cmake file to permit others to find it with find_package.
In SerialCommunication, to generate this file, you have to create a SerialCommunicationConfig.cmake.in that will be handled by sofa_create_package.

See how it is done for example in the LeapMotion plugin 😉

Guillaume.

[bgarcial]

Hi Guillaume.

I don’t understand what is FindSerialComunication because the name of my plugin is SerialComunication. Aditionally, I’ve created SerialComunicationConfig.cmake.in but anyway continues.

The structure directory of my SerialComunication plugin is:

SerialComunication
CMakeLists.txt
initSerial.cpp
SerialComunicationConfig.cmake.in
SerialDriver.cpp
SerialDriver.h

and SerialComunicationConfig.cmake has the following content:

# CMake package configuration file for the LeapMotion library

@PACKAGE_INIT@

set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH} @CMAKE_MODULE_PATH@")

find_package(SofaFramework REQUIRED)
find_package(SofaBase REQUIRED)
find_package(SofaGeneral REQUIRED)

#link_directories(@LEAP_INCLUDE_DIR@)
#find_package(Leap REQUIRED)

if(NOT TARGET SerialComunication)
    include("${CMAKE_CURRENT_LIST_DIR}/SerialComunicationTargets.cmake")
endif()

set(SerialComunication_LIBRARIES SerialComunication)
set(SerialComunication_INCLUDE_DIRS @PACKAGE_SERIALCOMUNICATION_INCLUDE_DIR@)

[bgarcial]

Hi Guillaume, I don’t understand what is FindSerialComunication because the name of my plugin is SerialComunitacion. Additionally, I created SerialComunicationConfig.cmake.in but anyway the error continues.

[Guillaume]

Hi,

Sorry I didn’t mean FindSerialCommunication but SerialCommunication. I just updated my previous post.

Could you show me the CMakeLists.txt of SerialCommunication and the CMakeLists.txt of ZeroMQCommunication please?

We are close to the solution 😉
Guillaume.

Hi Guillaume, thank you so much for your help, here is the code of those files:

[Guillaume]

As I said in my previous reply, to use SerialCommunication from ZMQCommunication you have to make SerialCommunication findable by creating a SerialCommunicationConfig.cmake.in (you did it) AND by calling sofa_create_package in SerialCommunication’s CMakeLists.
To understand what sofa_create_package does, check SofaMacros.cmake

Here is a corrected version of SerialCommunication’s CMakeLists:

cmake_minimum_required(VERSION 2.8.12)
project(SerialComunication)

set(${PROJECT_NAME}_VERSION 1.0)

set(HEADER_FILES
	SerialDriver.h
)

set(SOURCE_FILES
	SerialDriver.cpp
	initSerial.cpp
)

find_package(SofaFramework REQUIRED)
find_package(SofaBase REQUIRED)
find_package(SofaGeneral REQUIRED)

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}")
include_directories("${CMAKE_CURRENT_SOURCE_DIR}/..")

add_library(${PROJECT_NAME} SHARED ${HEADER_FILES} ${SOURCE_FILES})
set_target_properties(${PORJECT_NAME} PROPERTIES COMPILE_FLAGS "-DSOFA_BUILD_SERIALPLUGIN")
target_link_libraries(${PROJECT_NAME} SofaCore SofaComponentGeneral)

## Install rules for the library; CMake package configurations files
sofa_create_package(${PROJECT_NAME} ${${PROJECT_NAME}_VERSION} ${PROJECT_NAME} ${PROJECT_NAME})

install(DIRECTORY examples/ DESTINATION share/sofa/plugins/${PROJECT_NAME})

[Guillaume]

Any progress @bgarcial?

[bgarcial]

Hi @guillaumeparan
At this moment my partner and I we are awaiting find us again to test this latest consideration which you gave us.

Coming soon we keep you informed about it.
Thanks for being pending

[bgarcial]

Hi @guillaumeparan
Again, thanks a lot to you for the support. Our apologies for the late in response in relation to the progress topic.

The last recommendation that you give us it’s working, finally, we can call SerialCommunication Plug-in from ZeroMQCommunication, but when we can try to apply the opposite objective, Call ZeroMQCommunication from SerialCommunication we got the following error:

CMake Error at applications/plugins/SerialComunication/CMakeLists.txt:18 (find_package):

install(DIRECTORY examples/ DESTINATION share/sofa/plugins/${PROJECT_NAME})

In addition, we did have to make ZeroMQCommunication findable by creating a ZeroMQCommunicationConfig.cmake.in file which has the following content:

# CMake package configuration file for the ZMQCommunication library

@PACKAGE_INIT@

set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH} @CMAKE_MODULE_PATH@")

find_package(SofaFramework REQUIRED)

Thank you for your help.

[bgarcial]

Hi @guillaumeparan

My apologies for the inconvenience
Can you give us any suggests or recommend it?

In addition I was not correctly making the mention to your username profile @guillaumeparan 😛

[Guillaume]

Hi,

I never tried to create a circular dependency between plugins and I don’t think it is a good idea actually.
Are you sure your design is OK?

Guillaume.

[bgarcial]

Hi @guillaumeparan.

Again thanks for your support 🙂

Is possible that I did haven’t a clear explanation in my latest posts in this question. It’s not circular dependency, at this moment, we want a call to ZeroMQCommunication from SerialCommunication and nothing more. Of course, a circular dependency it’s definitively a bad idea.

Basically, the error which we get it’s related to our firsts interactions on this question, but we cannot meet how to address it.

In this latest post on this question we are making to make ZeroMQCommunication findable by creating a ZeroMQCommunicationConfig.cmake.in but the error persist

[bgarcial]

I’ve created and builded on SOFA of a separately way these two plugins:

/applications/plugins/SerialComunication – SerialComunication plugin
/applications/plugins/ZeroMQCommunication – ZeroMQCommunication plugin

On my plugins/CMakeLists.txt global configuration plugins I’ve added together plugins in this way:

sofa_add_plugin(SerialComunication SerialComunication)
sofa_add_plugin(ZeroMQCommunication ZeroMQCommunication ON)

Currently, I want from SerialComunication plugin call or include the ZeroMQCommunication

In other question, @guillaumeparan was supported me in relation to this task. He told me the following:

Every SOFA plugin has to generate a MyPluginConfig.cmake file to permit others to find it with find_package.

Then, in ZeroMQCommunication, I’ve created the ZeroMQCommunicationConfig.cmake.in file based on the same file in the LeapMotion plugin

So, this is my ZeroMQCommunicationConfig.cmake.in file:

# CMake package configuration file for the ZeroMQCommunication library

@PACKAGE_INIT@

set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH} @CMAKE_MODULE_PATH@")

find_package(SofaFramework REQUIRED)
find_package(SofaBase REQUIRED)
find_package(SofaGeneral REQUIRED)

# link_directories(@LEAP_INCLUDE_DIR@)
# find_package(Leap REQUIRED)

if(NOT TARGET ZeroMQCommunication)
    include("${CMAKE_CURRENT_LIST_DIR}/ZeroMQCommunicationTargets.cmake")
endif()

set(ZeroMQCommunication_LIBRARIES ZeroMQCommunication)
set(ZeroMQCommunication_INCLUDE_DIRS @PACKAGE_ZEROMQCOMMUNICATION_INCLUDE_DIR@)

In this way, I did make findable to ZeroMQCommunication plugin and from the SerialComunication/CMakeList.txt I’ve added the following directives line variables:

find_package(ZeroMQCommunication REQUIRED) to find the ZeroMQCommunication plugin. I guess that makes this via ZeroMQCommunicationConfig.cmake.in file created previously, I am not sure …

target_include_directories(${PROJECT_NAME} PUBLIC "$<BUILD_INTERFACE:${ZeroMQCommunication_INCLUDE_DIRS}>") to get access to ZeroMQCommunication plugin files

target_link_libraries(${PROJECT_NAME} ZeroMQCommunication) to linking with ZeroMQCommunication plugin

Then my SerialComunication/CMakeList.txt file has been stayed complete in this way:

cmake_minimum_required(VERSION 2.8.12)
project(SerialComunication)

set(HEADER_FILES
	SerialDriver.h
)

set(SOURCE_FILES
	SerialDriver.cpp
	initSerial.cpp
)

find_package(SofaFramework REQUIRED)
find_package(SofaBase REQUIRED)
find_package(SofaGeneral REQUIRED)

# Added
find_package(ZeroMQCommunication REQUIRED)

# list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}")
# include_directories("${CMAKE_CURRENT_SOURCE_DIR}/..")

add_library(${PROJECT_NAME} SHARED ${HEADER_FILES} ${SOURCE_FILES})

# ----------------------------------------
# Added. Get access to ZeroMQCommunication plugin files: 
target_include_directories(${PROJECT_NAME} PUBLIC "$<BUILD_INTERFACE:${ZeroMQCommunication_INCLUDE_DIRS}>")
# ---------------------------------------
# ----------------------------------------
# Added. Linking with ZeroMQCommunication
target_link_libraries(${PROJECT_NAME} ZeroMQCommunication)
# ----------------------------------------

set_target_properties(${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "-DSOFA_BUILD_SerialComunication")
include_directories("${CMAKE_CURRENT_SOURCE_DIR}/..")

install(TARGETS SerialComunication
        RUNTIME DESTINATION bin
        LIBRARY DESTINATION lib
        ARCHIVE DESTINATION lib)

Finally, Guillerme told me that is necessary use the sofa_create_package directive which will handle ZeroMQCommunicationConfig.cmake.in file, or at least that’s what I understood 😛

Then, until here, I’ve made findable ZeroMQCommunication from SerialComunication. Now I should call the sofa_create_package in the ZeroMQCommunication/CMakeList.txt which has stayed of the following way:

cmake_minimum_required(VERSION 2.8.12)
project(ZeroMQCommunication)

set(HEADER_FILES
    initZeroMQCommunication.h
    ZMQClientComponent.h
    PointNet.h
    SofaTypeMessages.h
)

set(SOURCE_FILES
    initZeroMQCommunication.cpp
    ZMQClientComponent.cpp
    PointNet.cpp
    SofaTypeMessages.cpp
)

set(EXTRA_FILES
    README.md
)

find_package(SofaFramework REQUIRED)
find_package(SofaBase REQUIRED)
find_package(SofaGeneral REQUIRED)

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}")
include_directories("${CMAKE_CURRENT_SOURCE_DIR}/..")

add_library(${PROJECT_NAME} SHARED ${HEADER_FILES} ${SOURCE_FILES} ${EXTRA_FILES})
target_link_libraries(${PROJECT_NAME} -lzmq ${} SofaCore)
set_target_properties(${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "-DSOFA_BUILD_ZEROPLUGIN")
# set_target_properties(${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "-DSOFA_BUILD_SERIALPLUGIN")
# set_target_properties(${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "-DSOFA_BUILD_ZeroMQCommunication")
target_link_libraries(${PROJECT_NAME} SofaCore SofaComponentGeneral)

## Added! Install rules for the library; CMake package configurations files
# sofa_create_package(${PROJECT_NAME} ${${ZEROMQCOMMUNICATION}_VERSION} ${PROJECT_NAME} ${PROJECT_NAME})
sofa_create_package(${PROJECT_NAME} ${${PROJECT_NAME}_VERSION} ${PROJECT_NAME} ${PROJECT_NAME})

install(DIRECTORY examples/ DESTINATION share/sofa/plugins/${PROJECT_NAME})

When I build sofa I get this error:

Is very very possible that something it’s wrong of my part in all these configuration and call process described above …

I’m sure there is an obvious fix for this, or unless more logic but I haven’t found it yet even despite of Guillerme support

[Guillaume]

Hey, I just merged your new topic to this one, no need to separate both.

Thanks for the summary but I’m still unsure of which plugin you want to be the parent plugin and which one to be the child plugin.

Anyway, here are my advices rephrased with “parent plugin” and “child plugin”.

– The parent plugin must be findable so it has to contain a XXXConfig.cmake.in file and to call sofa_create_package in its CMakeLists.

– The child plugin must call find_package to find the parent plugin and will then be able to link with it in target_link_libraries.

– The two plugins must be added with sofa_add_plugin in the right order: first the parent, then the child.

Hope that helps,
Guillaume.

[bgarcial]

Hi Guillaurme, it’s true, my apologies for create a new post with the same topic.

Currently, and with your analysis about of plugin child and parent plugin, my needs are related with the first question on this topic question in where from ZMQCommunication (parent plugin), I include to SerialCommunication (child plugin)

In this way I was able to get what I wanted, which was a first step to start integrating these two plugins/components into a scene

In this ideas order my question has been solved

Thaks a lot for you for the support. 🙂
