I am having difficulty building CMake on AIX 7.1 using IBM XL C 13.1.3,
which seems to be the newest version as of April 2017.
The bootstrap script fails with the following error:
---------------------------------------------
CMake 3.10.1, Copyright 2000-2017 Kitware, Inc. and Contributors
Found XL toolchain
C compiler on this system is: xlc
---------------------------------------------
Error when bootstrapping CMake:
Cannot find a C++ compiler supporting C++11 on this system.
Please specify one using environment variable CXX.
See cmake_bootstrap.log for compilers attempted.
---------------------------------------------
Log of errors: src/cmake-3.10.1/Bootstrap.cmk/cmake_bootstrap.log
---------------------------------------------
Given that AIX is explicitly listed as a supported platform, and I am using
the latest version of the IBM AIX compiler, I find this error dubious.
Below is a the contents of the cmake_bootstrap.log, where we can see that
it does try to use the appropriate -q flag to enable the compiler's
supported C++11 features.
Is XL C simply unsupported?
