Module Name:othersrc Committed By: agc Date: Sat Dec 4 01:54:51 UTC 2021 Modified Files: othersrc/external/bsd/agcre/dist: agcre.c agcre.h Log Message: Add visibility definitions for agcre. For any sources embedding these routines, simply define HIDE_AGCRE, before including the agcre.h header file, and the routines will have the hidden visibility attribute set on them. For more information on that, see https://gcc.gnu.org/wiki/Visibility To stop agcre routines being exported in a .so, simply define HIDE_AGCRE - I've been doing this successfully in library Makefiles, for example, this is from elex/lib/Makefile (elex is a library that calls the agcre functions): # set symbol visibility for .so CPPFLAGS+= -DHIDE_AGCRE and the agcre symbols will be found just fine when linking and running, but will not be exported by the linker. This can save headaches, and weird crashes, especially when combined with ASLR (when two libraries define the same symbol, but with different structs or arguments).
