when cross compiling OpenAL isn't detected #151

Open BielBdeLuna opened 8 years ago

BielBdeLuna commented 8 years ago

I've been trying to cross compile ( from Linux to Windows ) with that script: https://github.com/dhewm/dhewm3/pull/150 which is the implementation of the process the readme states.

if I compile for Linux, Cmake detects everything withouth any trouble: 

(...)
-- Found ZLIB: /usr/lib/x86_64-linux-gnu/libz.so (found version "1.2.8") 
-- Found JPEG: /usr/lib/x86_64-linux-gnu/libjpeg.so  
-- Found OGG: optimized;/usr/lib/x86_64-linux-gnu/libogg.so;debug;/usr/lib/x86_64-linux-gnu/libogg.so  
-- Found VORBIS: optimized;/usr/lib/x86_64-linux-gnu/libvorbis.so;debug;/usr/lib/x86_64-linux-gnu/libvorbis.so

-- Found OpenAL: /usr/lib/x86_64-linux-gnu/libopenal.so  
(...)

so OpenAl is in the system! but if I cross-compile with the binaries: cmake -DCMAKE_TOOLCHAIN_FILE=../scripts/mingw_toolchain.cmake -DDHEWM3LIBS=../scripts/dhewm3-libs/i686-w64-mingw32 ../neo

I get an error when searching OpenAL:

and if I skip the binaries reference in Cmake:

cmake -DCMAKE_TOOLCHAIN_FILE=../scripts/mingw_toolchain.cmake ../neo

I get an error with the JPEG lib:

to me it seems like Cmake doesn't search OpenAl amongst the binaries correctly, or maybe I should use the x86_64 binaries? Can someone help me?

BielBdeLuna commented 8 years ago

I've tried using the x86_64 binaries and they give the same problem:

(...)

so it's got nothing to do with using one set of binaries or the other. Has anyone ever attempted to cross compile from Linux to Windows?
