Building Ogre 1.11 with Emscripten

Post by ProfessorJ »

Ogre Version: :1.11.2:

Hi, I am having problems building the latest Ogre with Emscripten.

I have had a problem building until I removed a line in OgreMain/CMakeLists.txt

Code: Select all

include_directories("${ZLIB_INCLUDE_DIRS}" "${ZZip_INCLUDE_DIRS}")
and now cmake is generating build files.

Code: Select all

> cmake -DCMAKE_TOOLCHAIN_FILE=/.../emsdk/emscripten/1.37.36/cmake/Modules/Platform/Emscripten.cmake .

you arrived at the segfault because you removed that line. Try using the master branch, the zlib problem should be fixed there.

I can build the source sample but now I'm trying to link Ogre from another project folder.

I'm getting unresolved symbols for zlib and zzip.

Code: Select all

warning: unresolved symbol: inflate
warning: unresolved symbol: inflateEnd
warning: unresolved symbol: inflateInit_
warning: unresolved symbol: inflateReset
warning: unresolved symbol: zzip_dir_close
warning: unresolved symbol: zzip_dir_open_ext_io
warning: unresolved symbol: zzip_dir_read
warning: unresolved symbol: zzip_dir_stat
warning: unresolved symbol: zzip_dirhandle
warning: unresolved symbol: zzip_error
warning: unresolved symbol: zzip_file_close
warning: unresolved symbol: zzip_file_open
warning: unresolved symbol: zzip_file_read
warning: unresolved symbol: zzip_seek
warning: unresolved symbol: zzip_strerror_of
warning: unresolved symbol: zzip_tell
If I add the build flag -s USE_ZLIB=1

Code: Select all

warning: unresolved symbol: zzip_dir_close
warning: unresolved symbol: zzip_dir_open_ext_io
warning: unresolved symbol: zzip_dir_read
warning: unresolved symbol: zzip_dir_stat
warning: unresolved symbol: zzip_dirhandle
warning: unresolved symbol: zzip_error
warning: unresolved symbol: zzip_file_close
warning: unresolved symbol: zzip_file_open
warning: unresolved symbol: zzip_file_read
warning: unresolved symbol: zzip_seek
warning: unresolved symbol: zzip_strerror_of
warning: unresolved symbol: zzip_tell
Not sure whether to use the build flag because zlib is in the dependenceis folder. I can see that it's being developed on the main branch so I'll keep using trial and error.

on emscripten ogre is linked statically - this means you must link your project against all ogredeps. (zzip, freetype, libz)
