2022-03-28cpp: Set default visibility of all symbols to hiddenIngo Klöcker1-0/+242
* configure.ac: Add -fvisibility=hidden to GPGME_CPP_CFLAGS if gcc supports the flag. * lang/cpp/src/Makefile.am (AM_CPPFLAGS): Add GPGME_CPP_CFLAGS. * m4/ax_gcc_func_attribute.m4: New. -- With this change all defined symbols are hidden by default, so that they are not exported anymore. All symbols that are part of the ABI and that shall still be exported are already marked as having default visibility. The m4 macro was taken from the website mentioned in the License header of the file. GnuPG-bug-id: 5906
