It's a linux lib, not a FreeBSd lib. And the devtools port
will go  
away (deprecated/expiration date set).

Bye,
Alexander.

I know, this is why I asked on the -emulation list

Is there a plan to make such a port against linux_base-fc?

Else I shall try to make a small port only for this lib.

No, linux development should be done with a linux_dist port,
it  
provides a more complete environment for this task.

If you need this linux lib we have two possibilities:
  1) make a port with it
  2) add it to the fc4 linux base

If there's only one or two ports which need the lib, I
suggest 1), if  
there are a lot more ports, I suggest 2).

Bye,
Alexander.

I need it only for one port (the next upgrade of
french/gibi), but it  
might be useful for other ports. Do you know if it is
commonly used?

I searched the ports tree. Only linux_dist-gentoo-stage3 and
linux_devtools has this file. I assume that it's not widely
used.
OK, for the first time I'll do a new port (which may be
incorporated
to linux_base-fc4 if needed further). Will the port name
linux-libf2c
be good?

Great! But this is libg2c, not libf2c

libg2c is part of the gcc-g77 rpm.
g77 has been replaced by gfortran in the gcc 4.x series.
gfortran doesn't need/use/build libg2c.

So if you want to still try to use this app (which seems to
be built
from the older g77/gcc compilers), you need to include a
dependency
on the gcc-g77 rpm.

As Alexander said, you can either include that rpm directly
in your
port or add a separate port for it.  To help decide, you
might have to
grub around the linux ports to see if anything else might
depend on
fortran stuff.

We probably don't want it in the fc4 linux base.  fc4 uses
gcc-4
and gfortran as opposed to the old g77.

Your other option is to see if you can find or build a
version of your
linux app based on a newer gcc/gfortran (that doesn't bring
in the
libg2c dependency).  This is best IMO if that option is
available.

That said, the new version of your port may then have a
dependency on
libgfortran and you may be trading one missing dep for
another.  I
have not looked to see if any of the linux-* ports have been
made that include libgfortran.  I suspect not.  In fedora
core, that
lib is in the libgfortran rpm.

Yea, it's the library name, but the package name is
compat-libf2c-32-3.2.3-47.fc4.i386.rpm. 
OK, let it be linux-libg2c.

I'm testing the new port.

I forgot about the compat-* rpms in fc4 (gone in fc5, fyi).

But I don't think we should put compat-* rpms in the linux
base port.
Depending on old compat libs is not very
"basic".

If compat libs are needed, they should probably go in a
separate port
or ports.

And perhaps that port should named with
"-compat-" to emphasize that
it contains less (or not at all) actively supported packages
and for
easier searches.

Unfortunately, Gibi is a closed source application, and I
cannot change
it (it's why it has to run under Linux emulation on i386
only).

But Boris has ported this lib as
"lang/linux-libg2c": I have just tested
it, and everything works fine!
