g77 and gfortran together

Brian Salter-Duke

2005-04-21, 3:59 am

I use g77 all the time for my research code, but I want to play with
gfortran. I am currently using Fedora Core 3 with gcc/g77 version 3.4.2.
I have rpm's of the Fedora CDs for gcc4 and gfortran.

Can I install gfortran and have no conflicts with g77?

Do I have to also install gcc4? Again if this is named gcc4, are there
conflicts?

I realise that gcc4 and gfortran are still in development. Should I
download the latest versions or would it be OK to play with the ones on
the Fedora CD - gfortran 4.0.0-0.8 - for a while and upgrade when it gets
more serious?

Brian.

Yes, you can install both and no conflict will arise.
Note, however, that if you compile a library with g77
you can't link that library with a program compiled by
gfortran. There is a patch to gfortran to add this
functionality, but further testing is needed before
it is added to repository.

Yes, you need to install gcc 4.0.0 or mainline. If you
compile from source, you can do

../configure --program-suffix=4 --prefix=/usr/somedir --languages=c,f95

to install gcc4 and gfortran4 in somedir, which you can
add to your path.

Go to www.gfortran.org. There are pre-compiled versions that
are kept up to date, so the latest fixes are available.

I would suggest downloading the latest versions; bug fixes are ongoing,
and one of the advantages of your playing with the latest version is
that it can be helpful to the gfortran developers if you do find
something that doesn't work.

I'd also recommend reading the gfortran developer's mailing list;
there's a lot of information there about what's still buggy, and what
should be working, and such. An easy way to read it is via the Gmane
mail-to-news gateway; look at the gmane.comp.lang.fortran newsgroup on
the news.gmane.org news server.

Thank you most kindly. This is a very concise and helpfull description
of what I need to do.

What the hell are you thinking of? Read my subject line - gfortran and

Yes, that makes sense.

I use slrn to download gmane groups. I could not find
gmane.comp.lang.fortran (Is'nt it this group?). I did find however,
gmane.comp.gcc.fortran and gmane.comp.gcc.fortran.announce. Are these
the ones you meant?

Thanks for you help.

Brian,

Most of us try to ignore the particular troll who blasted you. He likes
to just throw out random insults just to see if he can get a response.
The more outrageous and irrelevant the insult, the more fun he seems to
have. You are lucky he didn't add in some racial slurs and profanity.
Don't take it personally; he does it to pretty much everyone. I suggest
a killfile entry or the equivalent for your newsreader. He's pretty
easily the newsgroup's biggest embarrassment. There's not even any point
in arguing with him; that just encourages more of it.

I'd also suggest that you consider g95 (www.g95.org) which looks to be a
bit further ahead in the development stakes at present than gfortran.
They both have a common base, of course.

The next question, I guess, is whether you can have g95 and gfortran
installed together without them conflicting. I may discover the answer
to that soon, at present I don't know. Certainly g95 does not conflict
with g77.

I've got them both installed. As far as I can tell they don't conflict. Of course,
gfortran can't compile any of my code yet, but ignoring that, they seem to reside side by
side quite nicely.

Have you submitted bug reports about gfortran ? If you don't like
gcc's bugzilla, send an email to fortran@gcc.gnu.org with details
about the problem.

I dont know about fedora core 3, but in debian you definitely can have
g77, gfortran together. In fact you can have multile gcc versions
installed on the same machine without any conflict. For an ordinary
user, The package manager (yum? in redhat) should take care of all that.

Hi Steven,

My apologies - I didn't word my original reply very well. What I meant by gfortran not
being able to compile my code was that some features have yet to be implemented, not that
it was buggy.

I wasn't offended or annoyed by your reply. Indeed, I will recommend
that people try g95 as well as gfortran due limitations in gfortran.
I just wanted to make sure that any bugs you find in gfortran get
into the bugzilla database.

You probably can do that in Fedora. With Redhat 7.2 before I upgraded
quite recently I had gcc 2.9 something and gcc 3.0 something installed
and used both of them.

Thanks to all for your help. I took the advice about g95 before reading
the advice!. I downloaded it last night, but I've just realised the
download must have failed part through while I was having dinner. I'll
do it again soon.

Brian.
