I've looked through that part of Libtool due to AIX issues and
discovered that export-symbols and its counterpart are not used for
linking programs at all. Only for libraries.
I don't know if this is intended behavior, but it is the way libtool
does things, even with 2.1
Hi all,
I'm running libtool 1.5.24 on linux (binutils 2.18) in link mode to
link C program with plugins. And I want to use -export-symbols to
export plugin API to plugins via standard linker without reinventing
dynamic linker (e.g. pass plugin some structure full of pointers to
functions).
When I pass -export-dynamic to libtool, then all symbols are exported
from main binary and my plugin using that symbols can be loaded via
dlopen() and it works fine, but exporting all symbols is a bit ugly.
When I pass -export-symbols or -export-symbols-regex to link main
binary - these options are _silently_ ignored, symbols are not
exported and plugin fails to load. :)
I've tested my ld and found that it supports option --dynamic-list,
that can be used to implement -export-symbols.
So my questions are:
1. is it right behavior or is it libtool bug?
1.a silent ignorance of option
1.b working -export-dynamic while linking program
1.c not working -export-symbols while linking program
2. what platforms support -export-symbols option?
