Need libmpc and dependencies

[Unisolve]

I loaded gfortran 4.5 but now I need various dependencies: libmpc, mpfr, gmp, and who knows how much more.
Is there a way to use rpm/yum or something else to make this easy? (yum resolvedep did not show anything)

Thanks.

CentOS-6 has gcc-gfortran-4.4.4-13.el6, gmp-4.3.1-7.el6, and mpfr-2.4.1-6.el6, and the corresponding -devel packages. EPEL has libmpc-0.8-3.el6 and libmpc-devel-0.8-3.el6. All are installable via yum. If you installed gfortran-4.5 you are probably on your own to find/build compatible packages.

"Who knows how much more" is who knows where. :-)

Hi, Phil,

I know gfortran 4.4 is there, but I need the 128-bit floating point support available in version 4.6 and up.
This is sure turning out to be much more than I was expecting. I'm surprised that 128-bit support seems
to be an experimental/leading edge feature on a 64-bit processor.

4.6 seems to be available for Fedora, but how do I resolve all the dependencies? Or do I assume wrongly
that a Fedora rpm will be compatible with CentOS? Can you suggest a best course of action? I already
have the raw binaries installed.

Thanks.

Walter

PS/EDIT: I see that I typed gfortran 4.5 in my initial message; I meant to put 4.6.

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

You will almost certainly end up having to rebuild the SRPM from source to get anywhere.

Trying to use Fedora binaries on CentOS is not recommended, for reasons you have demonstrated. I suspect that by the time you replaced enough core packages to satisfy the dependencies for the binary you would have an unstable Fedora/CentOS chimera.

If you must have a later version read about [url=http://wiki.centos.org/HowTos/RebuildSRPM]how to rebuild SRPMs[/url] and use the Fedora SRPM as a starting place, as Trevor recommends. If that starts running into dependency issues, then running Fedora, possibly via [url=http://wiki.centos.org/HowTos#head-fb1ff7e71fb5f2f511cda8c68cb6ba5f6e8decae]virtualization[/url], may be the best option.

[url=http://wiki.centos.org/FAQ/General#head-472ce8446ebcfc82ca1800f775ba0e629ac835c7]FAQ#20. Where can I get the latest version of XyZ.rpm for CentOS? I cannot find it anywhere.[/url]

From the gcc-fortran list I got the link to
http://gfortran.com/download/x86_64/gcc-infrastructure.tar.xz
which has the missing library: libmpc.so.2

But! after I unxz'd and untar'd it and copied the libraries into the
/usr/local/lib64 directory, it still gives the same error message:

/usr/local/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.6.2/f951: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory

I know I'm a newbie, but this is really odd.

[url=http://wiki.centos.org/PackageManagement/SourceInstalls]Source Installs[/url] are [b]highly[/b] discouraged. Package based systems should use packages if at all possible. Please read about [url=http://www.centos.org/modules/newbb/viewtopic.php?topic_id=14408&forum=47]Installing Software[/url].

That said, you may need to adjust the library path if you are going to install in non-standard locations.

Hi,

It finally occurred to me this morning what to try, and it worked.
This points out my ignorance about Linux and libraries and paths,
but I guess I can just chalk it up to experience and learning.
In my previous attempts, I had copied, I thought, everything to
the /usr/local/ tree for running it, but maybe not.

But this works:

Untar the binaries for gcc 4.6 and this support file:
http://gfortran.com/download/x86_64/gcc-infrastructure.tar.xz,
into some directory, i.e. gcc-4.6/, (moving over the libraries
(lib64/*) from the 'infrastructure' tar).
Then set
export LD_LIBRARY_PATH=~/gcc-4.6/lib64
I set an alias gf=~/gcc-4.6/bin/gfortran
and compiled with
gf test.for

and it worked! Finally!

Glad to hear that works for you, and it has the advantage of not replacing system packages with source installs. I hope it works in the long run as well, but would not be surprised to see issues with shared libraries.
