Bug 33936 – Perl PDL can't use GSL libraries

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Karl Steddom 2003-11-20 08:29:52 UTC]

Configuration for Perl::PDL gives errors when trying to locate GSL libraries
complains about:
The GSL_LIBS config variable must be a string (!)
 not a reference. You should probably leave it undefined
 and rely on gsl-config. Build will likely fail. 

$GSL_LIBS appears to be unset (ie. echo $GSL_LIBS returns nothing)

If I build PDL from CPAN, the gsl libraries are correctly found and compiled.


Reproducible: Always
Steps to Reproduce:
1.emerge gsl
2.emerge PDL
3.look at output of config step of PDL
4. emerge unmerge PDL, then install PDL in CPAN and gsl ok

Actual Results:  
The GSL_LIBS config variable must be a string (!)
 not a reference. You should probably leave it undefined
 and rely on gsl-config. Build will likely fail.

Expected Results:  
should have found gsl libs and written makefiles

I have tried this several times with the same results.

Created attachment 23364 [details, diff]
patch to files/perldl.conf


Fixes problem by removing old/incorrect syntax for the GSL_LIBS parameter in
perldl.conf. GSL_LIBS and GSL_INC are left as "undef" which means gsl-config
will be used to find the values (if GSL is installed that is).

Patch applied - thanks for your patience.
