Problems with rb-gsl on ubuntu

[Axel Etzold]

Dear all,

I am having problems with rb-gsl on ubuntu 8.04:

the (older) 1.9.2 version does not install its path anywhere, so it cannot be used without specially arranging
the path,
the actual 1.10.3 version does not install correctly (>ruby setup.rb install stops with...):

linalg.c:3532: warning: implicit declaration of function ‘gsl_linalg_hesstri_decomp’
make: *** [linalg.o] Error 1
setup.rb:655:in `command': system("make") failed (RuntimeError)
from setup.rb:664:in `make'
from setup.rb:1258:in `setup_dir_ext'
from setup.rb:1532:in `__send__'
from setup.rb:1532:in `traverse'
from setup.rb:1549:in `dive_into'
from setup.rb:1530:in `traverse'
from setup.rb:1524:in `exec_task_traverse'
from setup.rb:1519:in `each'
from setup.rb:1519:in `exec_task_traverse'
from setup.rb:1246:in `exec_setup'
from setup.rb:996:in `exec_setup'
from setup.rb:826:in `__send__'
from setup.rb:826:in `invoke'
from setup.rb:773:in `invoke'
from setup.rb:1578

Am I the first to experience this ? I think I had 1.9.2 install without path problems on ubuntu 7.10.

Best regards,

Axel

I ran into that problem a while back. I think that the
gsl_linalg_hessenberg_set_zero used to return an int but now returns
void. So:

On line 3488 of ext/linalg.c replace

return INT2FIX(gsl_linalg_hessenberg_set_zero(H));

with

gsl_linalg_hessenberg_set_zero(H);
return INT2FIX(0);
