Funny thing: $ cat CMakeFiles/CMakeOutput.log ... Performing Curl Test HAVE_GETHOSTBYNAME_R_5 passed with the following output: Change Dir: /home/mmalater/Dashboards/My Tests/CMake-xlC-9.0/CMakeFiles/CMakeTmp Run Build Command:/usr/bin/gmake "cmTryCompileExec/fast" gmake -f CMakeFiles/cmTryCompileExec.dir/build.make CMakeFiles/cmTryCompileExec.dir/build gmake[1]: Entering directory `/home/mmalater/Dashboards/My Tests/CMake-xlC-9.0/CMakeFiles/CMakeTmp' "/home/mmalater/Dashboards/My Tests/CMake-xlC-9.0/Bootstrap.cmk/cmake" -E cmake_progress_report "/home/mmalater/Dashboards/My Tests/CMake-xlC-9.0/CMakeFiles/CMakeTmp/CMakeFiles" 1 Building C object CMakeFiles/cmTryCompileExec.dir/CurlTests.c.o /opt/ibmcmp/vacpp/9.0/bin/cc -DHAVE_GETHOSTBYNAME_R_5 -o CMakeFiles/cmTryCompileExec.dir/CurlTests.c.o -c "/home/mmalater/Dashboards/My Tests/CMakeXLC/Utilities/cmcurl/CMake/CurlTests.c" "/home/mmalater/Dashboards/My Tests/CMakeXLC/Utilities/cmcurl/CMake/CurlTests.c", line 247.16: 1506-098 (E) Missing argument(s).

Yes, it is. There is a flag -qhalt=e which will cause the compiler to stop after all warnings marked with (E). ... This seems quite a common things to always add -qhalt=e in all configure script I found. Looking at what curl does with this compiler this leads to the following local changes for me: > cvs di Index: Modules/Platform/Linux-XL-C.cmake =================================================================== RCS file: /cvsroot/CMake/CMake/Modules/Platform/Linux-XL-C.cmake,v retrieving revision 1.2 diff -u -r1.2 Linux-XL-C.cmake --- Modules/Platform/Linux-XL-C.cmake 29 Sep 2009 17:56:57 -0000 1.2 +++ Modules/Platform/Linux-XL-C.cmake 30 Sep 2009 08:33:49 -0000 @@ -1,3 +1,23 @@ SET(CMAKE_SHARED_LIBRARY_C_FLAGS "") SET(CMAKE_SHARED_LIBRARY_LINK_C_FLAGS "") SET(CMAKE_SHARED_LIBRARY_CREATE_C_FLAGS "-qmkshrobj") + +# IBM_C) +# # +# dnl Ensure that compiler optimizations are always thread-safe. +# tmp_CFLAGS="$tmp_CFLAGS -qthreaded" +# dnl Disable type based strict aliasing optimizations, using worst +# dnl case aliasing assumptions when compiling.
