[john blair]

I am trying to build llvm-gcc4.2-2.6. 

My configure options are 

 $ /local/tools/lin32/llvm-gcc4.2-2.6/bin/llvm-gcc -v
Using built-in specs.
Target: i686-linux
Configured with: ../llvm-gcc4.2-2.6.source/configure --prefix=/local/tools/lin32/llvm-gcc4.2-2.6 --disable-nls --enable-shared --enable-threads=posix --enable-languages=c,c++ --with-gnu-as --with-gnu-ld --target=i686-linux --with-as=/local/tools/lin32/binutils-2.17.50.0.15/bin/i686-linux-as --with-ld=/local/tools/lin32/binutils-2.17.50.0.15/bin/i686-linux-ld --enable-llvm=/local/tools/src/llvm-gcc4.2-2.6/build-i686-linux-llvm/objdirllvm --program-prefix=llvm- --enable-libffi=no --enable-__cxa_atexit --with-sysroot=/local/tools/lin32/glibc-2.2.5-44 --disable-tls --enable-clocale=gnu
Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5649) (LLVM build)

I do a make bootstrap and make install after configure. 

But when I try to run this gcc I get

 $ /local/tools/lin32/llvm-gcc4.2-2.6/bin/i686-linux-llvm-gcc a.c
/local/tools/lin32/binutils-2.17.50.0.15/bin/i686-linux-ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

libgcc_s.so*  is presnet under /local/tools/lin32/llvm-gcc4.2-2.6/lib

Any ideas what is going wrong here? print-search-dirs gives the following which obviuosly does not include libgcc_s.so* path

$ /local/tools/lin32/llvm-gcc4.2-2.6/bin/i686-linux-llvm-gcc -print-search-dirs

llvm-gcc is not gcc.  You may have better luck asking on an LLVM
mailing list.

The library would normally be found via a search path like

/local/tools/lin32/llvm-gcc4.2-2.6/lib/gcc/i686-linux/4.2.1/../../../

Does that path work?

The path may be being disabled due to your --sysroot argument:
/local/tools/lin32/glibc-2.2.5-44.  Using --sysroot tells gcc where to
find all system libraries, and libgcc_s.so is put into a system
directory so that the dynamic linker can find it at runtime.  You may
need to copy libgcc_s.so into /local/tools/lin32/glibc-2.2.5-44/lib
along with the other system directories.

Thanks for the reply Ian. You are right --sysroot is messing the path. But I think this is specific to llvm-gcc the gnu gcc-4.2.1 works fine with --sysroot.

Hi,

Does anybody know anything about this ?

Here is the final output from make:

g++ -LANG:std -DCOMPILE_GCC -D_GNU_SOURCE  -I. -I../../lib/include
-I../../../lib/include   -Wno-non-template-friend -DPTHREADS -g
blabla.o blabla2.o -o vxs_server.Linux -L../../lib/lib.Linux
-L../../../lib/lib.Linux  -lrt -lThread -lMailbox -lServer -lDCSControl
-lClient -lCommandQueue -ldcsinfo -lDataDisk -lUnixSocket -lCommand
-lCapture -lCaptureIO -lThread -lBufferIF -lIngestConfig -lBufferQueue
-lSyncIF -lSNTPTime -lErrObj -lString -lCORE -lpthread -lc -lm
-ldcsVersion -lpthread
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status
make: *** [vxs_server.Linux] Error 1

It looks like an old bug ?

gcc version 3.0.1 on mandrake 8.1

Thanks for any help.

Vincent
