I'm trying to profile my graphic program which uses OpenGL. The program
worked correctly when I compile it without -pg flag. However, when I
compile it using -pg flag, it doesn't work correctly (i.e., it doesn't
read the obj file correctly, hence, doesn't display the image).
Is there a known bug with the -pg flag with OpenGL? This is my first time
using gprof and gcc -pg so I don't know if the bug is in my program or
from the -pg flag.
The question doesn't entirely make sense as written. Do you have a
problem at link time (you must use gcc -pg for both compile and link,
and it will not help you with precompiled shared libraries), or do you
have a problem at run time?
Do you expect people to guess details such as your OS and gcc version?
In my recent experience, -pg breaks applications which are close to
address subspace limits. I haven't found any solution for that.
