Hi,
I am trying to cross compile LLVM-3.0 for Arm target i.e. I would like to run the LLVM tools on ARM platform and generate the code for the ARM platform. I configured the build with
…/src/configure --build=i686-pc-linux-gnu --host=arm-linux-gnueabi --target=arm-linux-gnueabi --enable-optimized=no --prefix=/home/user/Acads/Compiler/LLVM/llvm-3.0/bin --with-as=/usr/bin/arm-linux-gnueabi-as --with-ld=/usr/bin/arm-linux-gnueabi-ld --with-ar=/usr/bin/arm-linux-gnueabi-ar
and then fire the build with
make -j4.
However following error occurs while doing the build,
make[2]: Entering directory `/home/user/Acads/Compiler/LLVM/llvm-3.0/build/tools/llvm-extract’
llvm[2]: Linking Debug executable llvm-extract
/usr/bin/ld: /home/user/Acads/Compiler/LLVM/llvm-3.0/build/Debug/lib/libLLVMSupport.a(regcomp.o): Relocations in generic ELF (EM: 40)

Will you please re-run with make VERBOSE=1 and show the exact cmdline?

So here it has not configures host as arm-linux-gnueabi as specified by in
the configure command. For the other time this statement occurs,
Target: i686-linux-gnu

In this case, the target is also configured as i686.
These seem to be outputs from gcc -v for your native & cross compilers.
