I'm building CMake 3.12.4 from the release tarball on AIX. CMake is failing to link on the machine:

ld: 0711-781 ERROR: TOC overflow. TOC size: 65632  Maximum size: 65536

The error is detailed in the IBM technotes at ld: 0711-781 ERROR: TOC overflow. I want to add -bbigtoc linker option for the cmake recipe.

CMake's bootstrap does not appear to accept linker options for LDFLAGS as shown below.

How do I add a linker flag to the bootstrap process?

Here are the options CMake bootstrap accepts:

$ ./bootstrap --help



Usage: ./bootstrap [<options>...] [-- <cmake-options>...]

Options: [defaults in brackets after descriptions]

Configuration:

  --help                  print this message

  --version               only print version information

  --verbose               display more information

  --parallel=n            bootstrap cmake in parallel, where n is

                          number of nodes [1]
