I'm compiling some sofware in Xcode that uses GTK libraries, and runs
in the X11 terminal. Everything compiles fine, but I get some warnings
in the linking stage (more on the warnings later). The application
runs, and apparently without issue, but in my (quite limited)
experience that most warnings come back to bite you in the posterior
after you've gotten much deeper in.
It's interesting to note that I've got a PowerBook and a desktop G4,
and when I compile on the powerbook, I get about 18 of these warnings,
and when I compile the same thing on the desktop, I get 187 of them.
The only explanation I can think of is that I downloaded the GTK
libraries at separate times using fink, so perhaps I have a slightly
different version of one of the multitude of libraries (though I
thought fink would take care of that). I guess another possibility is
that I have some preference set differently on the desktop version of
Xcode, but I really don't know what it would be, because I never mess
with preferences of Xcode. I just set it up once long ago and never
mess with it. And any preferences set in the project would carry over,
because I copied the entire project from the laptop to the desktop.
Now, about those warnings... They all have the same gist, and all 187
of 'em start with "warning prebinding disabled because..."
Here are a few examples:
ld: warning prebinding disabled because (__TEXT segment (address = 0x0
size = 0x27000) of /sw/lib/libpangoxft-1.0.0.dylib overlaps with
__LINKEDIT segment (address = 0x1b000 size = 0x8000) of
/sw/lib/libatk-1.0.0.dylib
ld: warning prebinding disabled because (__DATA segment (address =
0x27000 size = 0x1000) of /sw/lib/libpangoxft-1.0.0.dylib overlaps with
__TEXT segment (address = 0x0 size = 0x6f000) of
/sw/lib/libgdk-x11-2.0.0.dylib
ld: warning prebinding disabled because (__LINKEDIT segment (address =
0x28000 size = 0xa000) of /sw/lib/libpangoxft-1.0.0.dylib overlaps with
__TEXT segment (address = 0x0 size = 0x6f000) of
/sw/lib/libgdk-x11-2.0.0.dylib
I'm new at this, so I don't really understand what's going on during
the linking phase. It's running, so it's obviously linking (at
runtime?), but like I said, 187 of these errors/warnings is a lot to
just ignore.
Also, since it says there's an address conflict with all these
libraries, so I'm surprised it doesn't just error out and dump, either
when linking or running. I haven't gotten very far into the program
yet--still learning how to set up the UI, so I'm afraid I'll hit one of
these overlaps later on, like when I'm 99% finished, and then will have
to go back and make major revisions.
That's my story. So, any suggestions?
Thanks for your help,
Brian
