build package

[Patrick Dupre]

Hello,

I am rebuilding the perl packages that I need.
perl-Math-GSL-0.40.tar.gz


rpmbuild -bb perl-Math-GSL.spec 

gives an error:
Checking for GSL using gsl-config
Found GSL 2.6 (via gsl-config) installed in /usr
Checking if gcc supports "-Wall"...yes
Checking if gcc supports "-Wno-sometimes-uninitialized"...yes

unsupported version: 2.6 at Build.PL line 77.
error: Bad exit status from /var/tmp/rpm-tmp.I4k1Cb (%build)

Checking on the Build.PL file;
it seems to be due to

my $ver2func = Ver2Func->new( $gsl_conf->{gsl_version} );


The same version of perl-Math-GSL compiled fine with fc30.
(same version of cpanspec)
Now the gsl version is 2.6 (2.4 before)

Do I need to recompile gsl ?

No, that wouldn't change anything as long as GSL 2.5 is the maximum
version that is supported by Ver2Func. You could check the release notes
of GSL 2.6 to figure out how compatible it is.

https://github.com/leto/math--gsl/issues/176 is a request for
GSL 2.6 support from last month.

Until upstream finishes making the necessary changes you are stuck using an
old gsl.
You might consider helping (testing, documenting) with the changes.  I use
Fedora
precisely so I can discover and work on issues like this for the software I
use.

The library SONAME has changed from libgsl.so.23 to libgsl.so.25, but
libgslcblas.so.0 hasn't changed, and the Fedora packages would conflict
anyway because they include executables and other files. Therefore you
cannot simply install the old Fedora packages of gsl-2.4 and gsl-2.6
in parallel.

Depending on your usage scenario, you could compile GSL 2.4 yourself
and install it into a private path, then build other stuff (like Perl
modules) against it and override $LD_LIBRARY_PATH whenever you want the
runtime linker to find the old GSL libs.
