LAPACK/ScaLAPACK Development

Hi all.

I am trying to install lapack 3.1.1 on an Intel Xeon quad core running RH Enterprise 5.0 x86_64 using gfortran 4.1.1. I am using the same settings as in make.inc.gfortran.

Compilation fails with

Code: Select all

f77   second_INT_ETIME.f     -o second_INT_ETIME
/usr/lib/gcc/x86_64-redhat-linux/3.4.6/libfrtbegin.a(frtbegin.o): In function 'main':
(.text+0xle): undefined reference to 'MAIN__'


Any idea how to solve this?
Thank you

loris.
It looks like you copy command fails and you really modify incorrectly your make.inc
Copy the make.inc.gfortran from the INSTALL directory to make.inc

Code: Select all

cp INSTALL/make.inc.gfortran make.inc

You should see the use of the gfortran compiler, not f77 , the optimization flag, the -c to tell the compiler not to link (and thus not to look for a main)
Something like that:

Code: Select all

gfortran -O2 -c second_INT_ETIME.f -o second_INT_ETIME.o

thank you. that worked. :)

the problem I had was due to the the editor I used left some formatting symbol at the end of the make.inc lines I modified. I opened the make.inc with emacs and found them.

thanks,
