Trouble compiling Taucs under Ubuntu 12.04

[Andrew Somorjai]

I tried compiling taucs_full under ubuntu and I'm getting the following errors. I first ran ./configure and I did this

several times so now it just says its up to date but running make stops around the part where the include files aren't

adequate even though I have stl, gcc, etc... installed. Any suggestions would be nice.

x@x:~/taucs_full$ ./configure

make: `configurator/configurator' is up to date.

x@x:~/taucs_full$ make

TAUCS expects to find g2c and I guess you use already gcc 4 where they
use gfortran instead of g77. You have two choices. Either you find g2c.a
and insert it to the path or you have to compile ATLAS with gcc 4 and
then use -lgfortran istead of -lg2c.

Everything is changing but TAUCS remains the same.
