diff configure.ac @ 29647:bdb0cfffa2d0
Define variables for API visibility flags on all platforms (bug #59820).
* configure.ac: Check if platform supports visibility flags before using them.
Setup necessary compile flags if configured to use visibility flags.
* m4/acinclude.m4 (OCTAVE_DEFINE_MKOCTFILE_DYNAMIC_LINK_OPTIONS): Do not define
the flags for certain platforms only.
