Asp Forum - Lapack question - difficulties installing Linalg

Dear all,

I am having trouble installing the Linalg package.
I am working on OpenSuse 10.2, and I installed the
Lapack from an rpm, successfully.
Now, I get the following:

dhcppc1:/usr/local/linalg-0.3.2-i686-linux-ruby18 # ruby install.rb config
config ext/lapack
checking for f2c.h... yes
checking for main() in -lf2c... no
A full LAPACK installation was not found.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/usr/local/bin/ruby
--with-f2clib
--without-f2clib
install.rb:127:in `config': configuration failed (RuntimeError)
from install.rb:78:in `each'
from install.rb:77:in `chdir'
from install.rb:77:in `each'
from install.rb:74:in `each'
from install.rb:124:in `config'
from install.rb:215:in `send'
from install.rb:215

I tried "ruby install.rb config --without-f2clib", but that doesn't work
either. What am I missing ?

Best regards,

Axel

I get the same thing on my Gentoo system. It looks like it needs two packages,
"f2c" and "libf2c" in addition to LAPACK. But installing them did not fix this.
I think it's a bug in linalg -- the date I see on RubyForge is 2004-06-25. "f2c"
is a Fortran-to-C translator that's positively prehistoric. It dates back to
when there wasn't a real Gnu Fortran compiler, so they translated Fortran to C
and used the C compiler. This may have worked three years ago but it probably
needs to get updated. If all you need is linear algebra/LAPACK, I think the
Ruby bindings to the Gnu Scientific Library ("gsl") have that.

I just installed Ruby-Gsl (https://rubyforge.org/projec...) successfully,
so you might want to see if it does what you want and installs on your system.

Actually, I was trying to get some speedup
for the clusterer gem to work ... the author of that
gem tells users to install Linalg.

So unfortunately rb-gsl (which I have also installed)
isn't helping here.

Thank you for your reply,

Axel
