I’m trying to load a module library via dl in such way, that the module can access globals from the main application. How is that possible to do?
I get an error message from dlopen saying library/name.so: undefined symbol: .... The only flag used is: RTLD_NOW.
The module itself is build with libtool with -module -avoid-version.
The answer is: use
-Wl,--export-dynamicwhen linking the main binary, so all symbols are automatically exported to the loaded libraries.Same question, just asked differently: Receive "undefined symbol" error when loading library with dlopen
