In this article, I will describe the assembly of a project consisting of several libraries using Emscripten.
Emscripten does not currently support building shared libraries, so the first thing we do is translate all the libraries from Shared to Static. Emscripten works with its include files, so you need to solve the issue with the visibility of header files, I solved it by forwarding the symlink from the system directory to the Emscripten toolchain:
ln -s /usr/local/include/FlameSteelFramework $EMSDK/fastcomp/emscripten/system/include/FlameSteelFramework
If you use CMake, then you need to change SHARED-> STATIC in the CMakeLists.txt file of the add_library method. To build a library / application for further static linking, use the commands:
emcmake cmake .
emmake make
Next, you will need to build the main application indicating * .a library files at the linking stage. I could not indicate the relative path, the assembly completed correctly only after specifying the full paths in the CMakeLists.txt file:
elseif(EMSCRIPTEN)
target_link_libraries(${FSEGT_PROJECT_NAME} GL GLEW
