can not compile OpenMesh

bompo commented 12 years ago

Compiling of OpenMesh (http://www.openmesh.org/) fails.

I added the following lines to the cmake.txt:

SET(CMAKE_C_COMPILER          "/home/stefanw/emscripten/emcc")
SET(CMAKE_CXX_COMPILER        "/home/stefanw/emscripten/emcc")

after that I called "cmake .. && make"

Did I something wrong or isn't it possible to compile OpenMesh with emscripten? :/ Simple helloworld examples compile fine with emscripten and OpenMesh compiles fine with normal gcc but not with emscripten.

It seems to be more a clang issue than a emscripten one. Try to compile using clang directly and see if it works

Yeah it's a clang issue. Compiling with clang fails with the same error. Thanks
