Hi Viktoria
Beware of the difference of -l and -L as arguments to gfortran. -l specifies a library, -L specifies a library path.
So the correct gfortran line in your case would be
So how to get eclipse to use those options? Under Library Paths add
/home/verfurt/Schreibtisch/ws-f-calight-v642/ca-test-2/lib/
and under Libraries add
LChemApp
If you still run into problems, run the gfortran command that causes the problem from the command line and figure out what the correct paths and file names are and then set those options in eclipse.
Cheers

can you please help me to link a library to my project? I’m new with using eclipse and programming fortran. I have download eclipse and photran:
Eclipse for Parallel Application Developers Version: Luna Service Release 2 (4.4.2) Build id: 20150219-0600
It works so far. And I can compile a small “Hello World!” program without any problems. I want to use a library (name: libLChemApp.a) in my eclipse project. The same library works in a non-eclipse project on the same machine without any problems. I have put the library in my workspace. My directory tree looks like this:
ca-test-2: <- project - lib <- here is the library - src - debug - release
Now I have to tell the compiler where the library is which I want to use. How can I do it?
I have tried: Project->Properties Fortran General->Paths and Symbols
Includes: Add… Directory: /ca-test-2/lib The options: ‘Add to all configurations’, ‘Add to all languages’ and ‘Is a workspace path’ are enabled.
Libraries: Add… File: ${workspace_loc:/ca-test-2/lib/libLChemApp.a} The options: ‘Add to all configurations’, ‘Add to all languages’ and ‘Is a workspace path’ are enabled.
If I build the project I get an error:
13:36:02 **** Incremental Build of configuration Debug for project ca-test-2 **** make all Building target: ca-test-2 Invoking: GNU Fortran Linker gfortran -o "ca-test-2" ./src/ca.o -l"/home/verfurt/Schreibtisch/ws-f-calight-v642/ca-test-2/lib/libLChemApp.a" /usr/bin/ld: cannot find -l/home/verfurt/Schreibtisch/ws-f-calight-v642/ca-test-2/lib/libLChemApp.a collect2: Fehler: ld gab 1 als Ende-Status zurück make: *** [ca-test-2] Fehler 1
13:36:02 Build Finished (took 231ms)
But the library is in the workspace. Why cannot the compiler find it? What do I do wrong?
