[SOLVED] Import plugin in cpp

[bobiko]

Hi all,

I have encountered a problem with importing plugins in a cpp scene. I have tried:

simpleapi::importPlugin("SofaOpenglVisual");

and

sofa::helper:system::PluginManager::get_instance().loadPlugin("SofaOpengVisual");

but both ways produce the same output:

Plugin not found: "SofaOpenglVisual"

Here is a snippet of CMakeLists.txt:

cmake_minimum_required(VERSION 3.1)
project(hystsim)
find_package(SofaGui)
find_package(SofaSimulation REQUIRED)
find_package(SofaOpenglVisual REQUIRED)
find_package(CImgPlugin REQUIRED)

add_executable(${PROJECT_NAME} main.cpp scenemanager.cpp)
target_link_libraries(${PROJECT_NAME} SofaGuiMain SofaSimulationGraph SofaOpenglVisual CImgPlugin)

sofa lib dir is also added to LD_LIBRARY_PATH without any results. Could you tell what might be missing?

Vlad

Hey @bobiko

Great to see you again!
Hope everything is fine despite Covid19.

Which version are you using of SOFA?
– binary? which release?
– source? which release/branch/version?

Can you find the location of the libSofaOpenglVisual.so yourself?

Best,

Hugo

Hey @bobiko,

The Sofa’s libraries cannot automatically know what is your Sofa’s installation path, hence where the core plugins are located.

You can help them find it with the environment variable “SOFA_ROOT”, for example, if you built Sofa in the directory /home/bobiko/sofa/build:

$ export SOFA_ROOT=/home/bobiko/sofa/build
$ ./hystsim

Or by manually add the Sofa’s library path to the Plugin repository in your program:

main.cpp

sofa::helper::system::PluginRepository.addFirstPath("/home/bobiko/sofa/build/lib");
sofa::helper:system::PluginManager::get_instance().loadPlugin("SofaOpengVisual");

Hope that helped
