Re: Octave Compilation Error

[Himanshu B. Dave]

Thanks a lot for a quick response. 
I down-loaded and installed complete ATLAS package, with 
cblas and f77blas libraries, etc. Re-congiured and make'd
octave. Unfortunately still that error about missing "dormrz_"
SO I did the extreme hack: simply wrote a dummy.c file
with:
int dormrz_[100];
compiled it and included dummy.o in the  octave  make.
Now octave workes, except: the sparse matrix test fail
and give Segmentation Fault. Everything else, including GUI works.
All other tests are thro'.
Don't have enough time to investigate what is the  origin of   dormrz_
problem, or where is it hidden.
I am evaluating octave, scilab and MAYLAB for my teaching work and
can not spend enough time on straightening this out. 
Due to the place where I got Segmentation Fault, shows that dormrz_
is related to sparse matrix functions. I do not need them immediately.

AFAIK, the only problems I faced were that LAPACK, and BLAS that
gcc-4.1 picks up by default turned out to be the ones compiled by
g77 or something. So, following instructions posted at,
http://www.cae.wisc.edu/pipermail/help-octave/2007-October/006038.html
you can build your LAPACK, and BLAS.

Next using a configure script like,
/configure --prefix=$HOME/GCC42/ --with-f77=gfortran --enable-shared
--disable-static --with-blas=$HOME/GCC42/lib/libblas.a
--with-lapack=$HOME/GCC42/lib/liblapack.a

pointing your Makefiles to newly build LAPACK and BLAS.

Cheers,
