emmake: error: unable to find library -lTKernel

by

guys! I am trying to use emmake to compile a project containing OpenCascade api. When I used cmake .. and make commands, everying works fine! Note that I already installed OpenCascade on my machine. My CMakeLists.txt is as follow:

cmake_minimum_required (VERSION 3.0.0 FATAL_ERROR)
project(LessonOCAF CXX)
find_package(OpenCASCADE)
include_directories(SYSTEM ${OpenCASCADE_INCLUDE_DIR})
add_executable(LessonOCAF
    main.cpp
)
foreach(LIB ${OpenCASCADE_LIBRARIES})
    target_link_libraries(LessonOCAF debug   ${OpenCASCADE_LIBRARY_DIR}/lib${LIB}.so)
    target_link_libraries(LessonOCAF optimized ${OpenCASCADE_LIBRARY_DIR}/lib${LIB}.so)
endforeach()

My main.cpp is as follow:

#include <BRepPrimAPI_MakeBox.hxx>
#include <iostream>
using namespace std;

int main(int argc, char** argv)
{
    BRepPrimAPI_MakeBox mkBox(10, 20, 30);
    mkBox.Build();

    if (!mkBox.IsDone()) {
        return 1;
    }
    
    const TopoDS_Shape& shape = mkBox.Shape();
    cout << "successfully run occt demo! " << endl;
    return 0;
}

However, when I used emmake cmake .. and emmake make, I got errors:

wasm-ld: error: unable to find library -lTKernel
wasm-ld: error: unable to find library -lTKMath
wasm-ld: error: unable to find library -lTKG2d

Is there any way to fix this problem? Many thanks!!!

  • Have you compiled the libraries mentioned with emscripten?

  • What is content of OpenCASCADE_LIBRARIES variable which you create? (You could print the value of the variable using e.g. message(STATUS "OpenCASCADE_LIBRARIES: ${OpenCASCADE_LIBRARIES}").
