Bug#545806: libgsl0-dev: GSL should deal with an uninitialised rng better

Hello, By convention we've never checked whether pointers passed in by the user are actually non-NULL. This is mainly due to the amount of work in adding these checks everywhere. Also there would be a somewhat arbitrary distinction between functions where we would check, and those where we wouldn't because they would add too much overhead. -- Brian Gough Network Theory Ltd, Publishing Free Software Manuals --- http://www.network-theory.co.uk/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#456898: GSL linking issue with new '--as-needed' option to GNU ld [Was: Bug#456898: libgsl0ldbl: Uses symbols from libcblas.so, but not linked with it]

Is is maybe a question of link order, ie could -lgslcblas -lgsl be an answer? The option -Wl,--as-needed needs to be disabled in some way, if it's applied globally it's certainly not compatible with libraries that depend on other libraries (surely a fairly common occurrence?). The link order is not a factor. Maybe there is some official way to turn off that feature in qmake, or to make it behave more intelligently with regard to external libraries vs Qt libraries. Otherwise one could put the gsl library at the end of the libraries list with -Wl,--no-as-needed: -Wl,--no-as-needed -lgsl -lgslcblas -lm -- Brian Gough -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Bug#401036: gsl: FTBFS on GNU/kFreeBSD

Correct me if I'm wrong but I was not aware that the GNU/kFreeBSD port was an officially supported architecture -- so severity 'important' is inflated, no? Either way, the patch looks straighforwaed indeed and I am CCing Brian Gough as a heads-up. It is of course up to the GSL team to decide whether they apply it upstream or not, but I think I'll make a new release for Debian later today. Thank you, I have made the change below which should cover this and any other cases. -- Brian Gough (GSL Maintainer) Network Theory Ltd, Publishing the GSL Manual - http://www.network-theory.co.uk/gsl/manual/ Index: configure.ac === RCS file: /home/gsl-cvs/gsl/configure.ac,v retrieving revision 1.32 diff -r1.32 configure.ac 215c215 *86-*-linux* | *86_64-*-linux*) --- *86-*-gnu | *86_64-*-gnu | *86-*-linux* | *86_64-*-linux*) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Bug#307744: gsl_min_fminimizer_set documents errors inconsistently
| I suppose the bug is just a documentation one. The docs needs to say that | gsl_min_fminimizer_set returns GSL_EINVAL, not GSL_FAILURE, when the | interval is bad (though I wonder why they do not use GSL_EDOM - bad input | domain - instead). Thanks for the bug report. I will change the documentation to say GSL_EINVAL. -- Brian Gough Network Theory Ltd, Publishing Free Software Manuals --- http://www.network-theory.co.uk/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
