Unable to build main.cpp in SofaPhysicsAPI

[Olumide]

I added the line add_executable(App main.cpp) to applications/projects/SofaPhysicsAPI/CMakeLists.txt and reconfigured sofa using the UI. Here is the resulting error:

In file included from /home/Olumide/Downloads/src/sofa-src/sofa/src/applications/projects/SofaPhysicsAPI/main.cpp:22:0:

Hi @olumide

What are you changing the SofaPhysicsAPI from a library to an executable project? I am not sure to follow you.

Regarding SofaGeneral, it is also a deprecated collection (see #1596). It must be replaced by the appropriate package (e.g. SofaGeneralEngine, SofaGeneralDeformable etc.) depending on which is needed. These needed SofaGeneralEngine*.so should be explicit in the CMakeLists.txt (find_package + add_library).

Best,

Hugo

Hi @hugo,

I did not change SofaPhysicsAPI from a library to an executable project. I merely added an option to also compile an executable (from main.cpp) in addition to the library. It was just a test though, I’ll remove it.

I’m not sure that I understand the changes that I’m supposed to make regarding SofaGeneral. I’m going to have to study the project structure of sofa some more.

Hi @olumide

You make me think that we should provide more insight about the CMake package organization (e.g. knowing which code is located in which package). We will work on this.

Best,

Such a document would be most welcome @hugo.
