Hi,
I was wondering if it's possible to run MinGW-compiled osg program
under gdb? I can run it fine outside of gdb but when I run it in gdb, I
get this problem:
(gdb) r
Starting program: /usr/local/build/osg/bin/osglightd.exe
Breakpoint 2, main (argc=1, argv=0x3db140)
at
c:/cygwin/usr/local/src/OpenSceneGraph-2.4.0/examples/osglight/osglight.cpp:327
(gdb) c
Continuing.
