I have having some difficulties compiling the plplot package and I noticed that g77 provided by fink is 3.4 while gcc of the Apple Developer tools is 3.3.
There seems to be some inconsistency that could explain my problem.
- why did you swich to 3.4 for g77. According to GNU it does not seem to be stable yet ?
- is it still possible to get g77 3.3 as a fink package? I do not find it with fink commander.
In the 10.3/unstable tree, you have g77-3.3.2-2, too. You have to require this explicitly, i.e. "fink install g77-3.3.2-2", because there is also the 3.4 version. FinkCommander only shows the highest version available.
OTOH, g77-3.4 has been working quite well for me together with gcc-3.3, so I'd rather question the idea that your problems (what are they?) come from an incompatibility there.
The reason why Fink's g77 was promoted to 3.4 is a change in Apple's assembler in the June03 dev tools and later that unilaterally declared that a certain construction produced by the compiler is a bug. This construction is rather unusual in C and C++ code, but rather common in Fortran code.
The bug is still present in the gcc-3.3 that ships with Panther. Apple never bothered to fix it (it looks like their assembler guy doesn't talk to their compiler guys). Therefore a g77 compiled from Apple's gcc-3.3 sources would still have this bug (unless specifically patched or unless the assembler is replaced by the pre-June03 version). In the "official" (FSF) gcc sources, this bug was fixed in version 3.4. Maybe it was backported to version 3.3.2, I don't know.
In any case, g77-3.4 is free of this bug. As with g77-3.3.2, you'll have to see for yourself. The minimal example that exhibits the bug is a Fortran program consisting of a single line
END
If it compiles without error message, you are fine.
