Hi,
I need to build an app which needs a symbol from Pango library
which exists only in some newer versions.
Since pango_version_check is not available on older pangos, and I want
my app to run on all systems regardless of their pango version (since
the symbol I need is not crucial), I'd like to pose the following question:
How do I make sure that a symbol is in the Pango lib loaded at
runtime (I want to link my app against shared libs - i.e. DSO) used at
runtime?
I'd normally use dlopen() but given the LD_LIBRARY_PATH, RPATH and
RUNPATH mess, how do I know for sure which lib is being used by my
application?
The only solution I can think of is parsing the /proc/self/maps resource
and look at it... do you know a better solution?
Thanks,
Francesco Montorsi
