Eclipse-Photran, Cygwin and fortran90 linking problem

[tvandenbrande]

I installed eclipse, photran and cygwin with the gfortran compiler and lapack libraries on my Windows 7 machine. When trying to invoke the lapack library for two routines (dpbtrf and dpbtrs) I get the following error message:

Building file: ../Hamfem.f90
Invoking: GNU Fortran Compiler
gfortran -funderscoring -O3 -Wall -c -fmessage-length=0 -llapack -o "Hamfem.o" "../Hamfem.f90"

CYGWIN environment variable option "nodosfilewarning" turns off this warning.

Fatal Error: Can't open module file 'lapack.mod' for reading at (1): No such file or directory

I tried a few things already and can rule out the following:

• I installed all lapack libraries in cygwin (including the dev library)
• liblapack.a and libblas.a are located in the library folder C:/cygwin/lib

Does someone knows what settings in eclipse are wrong, or where I have to add or change things?

UPDATE:
I managed to resolve a few issues, by changing the properties in Eclipse like this:

• Fortran Project: executable GNU fortran on Windows (GCC toolchain)
• GNU fortran compiler: gfortran ${COMMAND} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${INPUTS}
• GNU fortran linker: gfortran ${COMMAND} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${INPUTS}
• I compiled the libraries libblas.a and liblapack.a, to use as a static library, for windows and they are located in the C:/cygwin/lib folder.
• In the GNU fortran linker properties, the libraries were called lapackand blasin the folder C:/cygwin/lib. This results in a part -L"C:/cygwin/lib" -llapack -lblas in the {$COMMAND} section of the compiler and linker.

Now the code compiles, but when running the resulting *.exe file I get the following error message:

Code: Select all

The program can't start because cyglapack-0.dll is missing from your computer. Try reinstalling the program to fix this problem.

This file does exist on my computer in the folder C:/cygwin/lib/lapack but was not included during the build. Does anyone have an idea to fix it?
