Mike,
   Depending on how you built/installed your gcc on AIX, eg from the IBM

freeware site or rolled your own, it should be under the gcc path for that compiler version.

find /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.1.1/ -name "libgcc_s*" /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.1.1/ppc64/libgcc_s.a

/opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.1.1/pthread/libgcc_s.a

/opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.1.1/pthread/ppc64/libgcc_s.a

/opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.1.1/libgcc_s.a

Note, however, that the binutils linker ld is generally considered broken for any C++ code on AIX unless this has been fixed since the 4.1.1 release. I use LIBTIFF extensively under AIX and I build by first setting environment variables for LD, RANLIB, and AR to point to the AIX versions. I set CC, CXX, MAKE, SED, AWK, and SHELL to point to the /opt/freeware/bin versions. You need current versions of libtool as well.

Since the binutils version of ld cannot handle the mixed 32/64 bit libraries on AIX and doesn't always do the right think for shared libraries, I have simply renamed/removed it so that it can never be found.

Mike,

First, find the library libgcc_s on the system. if you find it anywhere note down the path and add that path to env LD_LIBRARY_PATH

Then build the libtiff again. I hope it will resolve the issue

Any help would be greatly appreciated!!
