Hi Bill, Here is the output of running cmake version 2.8.9 on AIX 5.2. http://pastebin.com/yM46Ncse What I can see is that cmake fails to identify the compiler. Perhaps for that reason it seems to be trying an erroneous command-line later: /usr/bin/xlc_r CMakeFiles/cmTryCompileExec3576455604.dir/testCCompiler.c.o -o cmTryCompileExec3576455604 /usr/lib /lib I have got the same results by exporting CC=xlc and CXX=xlC and also CC=xlc_r and CXX=xlC_r. The version of IBM Visual Age on these machines is v7.0. I do not encounter any problems with normal Makefile based builds using this toolchain. I built cmake from source on this machine without any problems. I have a functional cmake-based build of my product on AIX 6.1 and Visual Age v8.0 which runs without any issues. Thanks.
