Stan,
I am involved in porting a C++ class framework we use at work to OSX
/ Darwin PPC so we can target OSX as well as Win32 and Linux. This
code demands gcc3.4, which shouldn't be an issue (gcc3.4 "make
bootstrap" seemed to work just fine on my 1.33GHz 12" PowerBook), but
I would like to, if possible, use gcc-select to choose between
Apple's gcc3.3 and FSFs gcc3.4. Has anyone else done this? I've not
researched how I would approach doing this yet (this posting is part
of that research <smile>).
It's just a shell script that you could hack up, but I don't recommend
you try - FSF 3.4 is missing dozens of features essential to building
Mac apps, such as framework path searching, alignment pragmas, and
similar kinds of bits. Some of those features are needed by system
headers and could cause interesting (heh) runtime problems. Ultra
portable pure ISO/K&R C code, such as what GCC itself is written in
(for reasons that should be obvious), will be OK, but just one Cocoa
or Carbon call can mess you up.
So I recommend you install gcc-3.4 under its own name only, and
have all of your 3.4-using code ask for 3.4 explicitly by name.
Will do. I won't be making any Cocoa / Carbon calls ... at least not
at this stage. Perhaps when Tiger comes out, it will sport a
super-cool Apple version of gcc3.4. Of course, by that time, our team
leader slash compiler jockey slash
FSF-just-released-a-new-version-of-gcc-3-minutes-ago-why-the-hell-
aren't-you-using-it-yet? will demand that we all use gcc4.0.x.y.z :-)
Regards,
John
