Re: [photran] Cannot find library file
Hi Fernando,

I'm no expert on this issue, but since no one else answered your question, I'll give it a try. (Maybe you already solved your problem on your own. In that case just ignore this message.)

I think it has to do with the way the -l option is treated by the linker. The documentation states that it takes the name of the library you specified, and prepends 'lib' and appends '.a' to it.
So when you use for instance the option -lmylib, the linker actually searches for a file named libmylib.a (I believe it also recognizes some other file extensions, but I'm not sure which). It automatically searches a couple standard directories and you can specify an extra directory to search with the -L option. So, in your case, with the complete path and file name after the -l option, the linker gets confused.

I think you have two options:
1. Change the name of the library, if you can, following the standard pattern, add its name (without path, lib prefix and file extension) to the 'Libraries' box (the -l option), and add the directory where it is located in the box for 'Library search paths' (the -L option).
2. Instead of under the Libraries section of the linker options, add the path and name of your library file under the Miscellaneous section, in the 'Other objects' box. I guess this is the easiest solution.

Let me know if this helps.

Greetings,
Erik.

Hello:

I have run into a problem.
I cannot get a library linked in a project, I always get messages like:
c:/gcc/bin/../lib/gcc/x86_64-pc-mingw32/4.5.0/../../../../x86_64-pc-mingw32/bin/ld.exe:
cannot find -lE:/Fer/eclipse/Fit41/levmardll_x64.lib
collect2: ld returned 1 exit status
make: *** [Fit41] Error 1
I included levmardll_x64.lib in Project Properties (right click in project
folder)->Fortran Build->Settings->GNU Fortran linker->Libraries; and also
in Fortran General->Paths and Symbols->Libraries, no luck either way.
But the path after '-l' is correct. What I am doing wrong?

Thanks all,

Fernando
