Dear GPC Users,
I think I have it all sorted now. It turns out that cctools installs
eighteen files in /usr/bin. Among these are "ld" that takes precedence
over the XCode2.5 "ld" if /usr/bin comes first in your directory search
Searching the likely directories on my hard drive with "ls -R | grep
crt1.o" I find no crt1.o installed except in the Xcode2.5 directory
tree. This leads me to conclude that cctools may install "ld" and "as"
but they do not install the "crt1.o" library required by GPC to make an
executable. So installing Xcode appears to be necessary on MacOSX10.5.
Of the eighteen files installed by cctools in /usr/bin, sixteen are
available in /Xcode2.5/usr/bin/. Only "lipo" and "strings" are unique to
/usr/bin. I deleted the uneccessary 16, leaving "lipo" and "strings".
The pre-cctools version of these files are no longer available to me.
But I built a universal binary with "lipo" and it seems to work.
After this removing the sixteen duplicate files from /usr/bin, my
compile works fine with the library search directive that Adriaan suggested:
and I can even add the convenient:
which is the flag that the cctools "ld" would not accept.
As to uninstalling XCode2.5, just deleting the XCode2.5 folder does not
remove the devtools files in the main UNIX file structure, so you have
to run XCode2.5/Library/uninstall-devtools, which gets rid of
everything. After that, you can re-install XCode2.5. But it still gives
me no UNIX Tools option.
