Eclipse-Photran, Cygwin and fortran90 linking problem

[tvandenbrande]

I'm trying to use the lapack library for two routines (DPBTRF and DPBTRS) in a fortran90 code that was previously compiled with a compaq compiler. We recently changed to gfortran and I can't get the lapack library in my programs. My current setup (on a windows7 machine):

• Eclipse with Photran 8.0 package
• Cygwin installation with the lapack libraries (including liblapack-devel)
• Cygwin directories added to the windows PATH

In the folder C:\cygwin\lib there are the lapack files:

• libblas.a
• libblas.dll
• liblapack.a
• liblapack.dll

There is also a folder called lapack with the files cygblas-0.dll and cyglapack-0.dll
Now, the project in eclipse-photran is a GNU fortran project (with the GCC toolchain) which generates its makefiles automaticly (because the program has quite a lot of subroutines and modules this is quite handy). When builing I get the following error-message:

make all

Does someone know what I did wrong and how I can include the lapack library?

There is no lapack.mod in the LAPACK package, because there is no LAPACK module.
I would take off that use statement.
