Re: [photran] Problems trying to debug in Mac OSX

[Ferran Mazzanti <Ferran.Mazzanti@xxxxxxx>]

Hi guys,

thanks you all for your kind replies :)
Right now I'm at work and can't check on my mac. I have checked that 
everything works on my Ubuntu 9.10
box following the steps and advices given. But on the mac... I have to 
check. i have been messing around with
it so much that now I cannot tell from heart what I did. i know I have 
the latest gfortran installed
which is 4.6 I believe... not from the macports as 8i think) that 
doesn't exists there. I got it from
http://hpc.sourceforge.net/
which installs and works nicely, apparently.
Another source of potential trouble is gdb itself... the one that ships 
with the mac developper tools,
integrated in Xcode, is prehistoric: it is version 6.3.5 while they are 
already at gdb 7,2
(and I'm talking about xcode 3.2.6 which is the latest one prior to the 
new 4.0 release).
That *is* a source of problems also since... guess what... gdb itself 
can't debug global variables
in COMMON's or Module's. Only starting at gdb 7.2 that seesm to work 
under gfortran
(I checked release 7.0 and that was not working either). But fortunately 
macports does have gdb 7.2
and one can install it. It goes under the name 'fsf-gdb' instead of 
'gdb' since the mac utilities
seem to require its own (pleistozenic) gdb version. So if everything 
works, one has to try it
with fsf-gdb, which is another source of potential trouble...

Looks like fortran and Mac OSX is a difficult combination. I may end up 
installing Parallels and
Ubuntu on the mac to do my fortran programming and debugging if 
everything else fails,
but that is far from being the optimal solution.

i'll try all that in my machine and see what comes up...

cheers,

Ferran.
