problem to compile taucs under linux (x86_64)

[swhsu]

Machine:
# 2 x 3.2GHz Intel Xeon dual core processors
# 32GB RAM
OS: SuSE Linux 11.1 (x86_64)
gcc version: 4.3.2

Hi all,

I got some troubles while I compiled the taucs under this machine.
At beginning, I downloaded the taucs package from the official
website, and compiled it.
It looks like the external library come with the package is
incompatible with this machine(?)...
The messages are in errors[1].

Then, I download the ATLAS (v3.9.16), lapack (v3.2.1) and metis (v4.0)
to generate 5 libraries
to replace the original libraries. (libatlas.a, libf77blas.a,
libcblas.a, liblapack.a, and libmetis.a)

After that, I built the taucs again, but it still got some problems...
The error messages are listed in errors[2].

Did I do something wrong?? Any suggestions?

Thank you!!

At the beginning TAUCS makes some checks and in your cases it was not
able to compile the test programs.

Here you should pay attention to

For some reason liblapack.a cannot be used and then taucs_config_tests.h
was not build.

Here presumably you have used gfortran but taucs uses g2c that is a lib
for g77. You have to change -lg2c to -lgfortran. Well, I do not know how
the gfortral run-time library is called, so please just correct it.

> Did I do something wrong?? Any suggestions?

You can compile the test programs by hand, then make will not try to
complile them again. Or make taucs_config_tests.h by hand by you have to
make it correctly otherwise you will have problems later on.

Basically you have to read and edit the makefile.
