Greetings all,

I am having a particularly hard time getting lapack, gfortran and cygwin to
play nice. I installed the lapack packages under the math section of
setup.exe, however, when I go to use them with gfortran, I get errors saying
gfortran can=92t find the libraries.

I am using the following command for my compilation:

$ gfortran test.for =96o test =96llapack

And the error I receive is=20

/usr/lib/gcc/i686-pc-cygwin/4.3.4/../../../../i686-pc-cygwin/bin/ld: cannot
find
=A0-llapack
collect2: ld returned 1 exit status

When I go to look for the lapack libraries, they are located in /lib/lapack
and there is a file called cyglapack-0.dll along with a similarly titled
BLAS DLL.=20

In the end, I am at a loss as to how to use lapack with gfortran in cygwin
after installing it.=20

Did I miss something easy or am I just doing this completely wrong?

Thanks in advance!

-Tim
