[gentoo-user] emerging IFC - Intel Fortran Compiler

[Richard Broersma Jr]

Hello all,

I am trying to install Fortran for a school project 
my wife is working on.

Are there any installation instructions better 
than the following ones?:

1) http://bugs.gentoo.org/show_bug.cgi?id=117452
   - my question with this link is, where is this overlay 
     directory that is mentioned?

2) http://gentoo-wiki.com/Talk:HOWTO_Installing_3rd_Party_Ebuilds
   - This link seems to have turn more into a discussion of the
     proper use of "~x86" in package.keywords


So far, I have the the following:
ftp://download.intel.com/software/products/compilers/downloads/l_fc_c_9.0.031.tar.gz
http://bugs.gentoo.org/attachment.cgi?id=76000  -- attached ifc-9.0.031.ebuild

But I am not sure exact where to put them or what to do with them. :-)

Any suggestions or links would greatly be appreciated.

Regards,

Richard Broersma Jr.

This is talking about creating a local portage overlay for your own
ebuilds.  You can set PORTDIR_OVERLAY=/usr/local/portage in
/etc/make.conf, and then create your own portage tree under
/usr/local/portage [1].

You really should not mess with overlays unless you really know what
you are doing.  However, you generally start by either:

1. Copying an existing category/package directory from the official
tree, and hacking on it your overlay.  This is useful if you want to
do a version bump or apply a patch that is not in the offical tree.

2. Creating your own category/package directory, and adding your own
ebuilds and/or patches.

Once you have created your ebuild, "ebuild <path_to_ebuild> digest"
will generate the MANIFEST and other necessary files.

However, dev-lang/ifc already exists.  If you want the latest 9.0.031
version, you'll have to accept the ~arch keyword, but this is
certainly a lot easier than trying to maintain your own overlay.

Yes, messing with making a package overlay doesn't should like
I really want to get into. However, in addition to add ~x86 how
do I get past the package restriction. I don't see any explaination
in the ifc.ebuild for version 9.0.031.

Thanks for the help.


db_server01 ifc # grep -e ifc < /etc/portage/package.keywords && emerge ifc
dev-lang/ifc ~x86
Calculating dependencies... done!

>>> Emerging (1 of 1) dev-lang/ifc-9.0.031 to /

!!! dev-lang/ifc-9.0.031 has fetch restriction turned on.
!!! This probably means that this ebuild's files must be downloaded
!!! manually.  See the comments in the ebuild for more information.

!!! The following are listed in SRC_URI for ifc:
!!!   l_fc_c_9.0.031.tar.gz

Any reason you can't use gcc's Fortran compiler?

Why do you need an overlay? ifc's in the main tree.

Thanks,

I would be happy to, I didn't know there was one. Is there any docs that explain how to the gcc
fortran complier?

USE=fortran emerge gcc

If you're on gcc4, it's gfortran and is Fortran95 (and older) 
compatible. If you're on gcc3, it's g77 and is (as one would expect) 
compatible with Fortran77.

Thanks,
