Building a 32-bit version of Mesa requires a 32-bit version of LLVM. It sounds like you only have the 64-bit version installed. Alternatively, you can use --disable-gallium-llvm and both --with-gallium-drivers and --with-dri-drivers to specify which drivers you want to build. If you don't actually need radeon or llvmpipe, then you don't need LLVM. If you need help, you might try asking on IRC. I build LLVM like this: #-------------------------------- mkdir build cd build export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig export CC="gcc -m32" export CXX="g++ -m32" cmake .. \ -DLLVM_BUILD_32_BITS:BOOLEAN=ON \ -DBUILD_SHARED_LIBS:BOOL=ON make #-------------------------------- #--------------------- $ ls /usr/local/bin/ avcenc* llvm-cov* llvm-mcmarkup* loadjpeg* bugpoint* llvm-c-test* llvm-nm* mpeg2vaenc* c_rehash* llvm-cxxdump* llvm-objdump* mpeg2vldemo* h264encode* llvm-diff* llvm-pdbdump* obj2yaml* jpegenc* llvm-dis* llvm-profdata* openssl* libtool* llvm-dsymutil* llvm-ranlib@ opt* libtoolize* llvm-dwarfdump* llvm-readobj* putsurface* llc* llvm-dwp* llvm-rtdyld* sancov* lli* llvm-extract* llvm-size* vainfo* llvm-ar* llvm-lib@ llvm-split* verify-uselistorder* llvm-as* llvm-link* llvm-stress* xmlwf* llvm-bcanalyzer* llvm-lto* llvm-symbolizer* yaml2obj* llvm-config* llvm-mc* llvm-tblgen* #--------------------- #--------------------------------------------------- $ objdump -p /usr/local/bin/llvm-config | grep format /usr/local/bin/llvm-config: file format elf32-i386 #--------------------------------------------------- I Re Open, because I need all drivers, so I need find way how compile LLVM for Mesa. In your command line for building Mesa, you should change `--with-llvm-prefix=/usr/local/bin` to `--with-llvm-prefix=/usr/local` as it changes where the *root* folder of your llvm installation is, not the folder where it will find the llvm binaries. It working ! Thanks Pierre ! :D Problem SOLVED |
