Hello, I simply need to link a fortran source to a library: plplot. This is how i did it. _____________________________________________ gcc -o x01f.exe x01f.f \ "C:\Program Files\plplot\bin\libplplotf77d.dll.a" \ "C:\Program Files\plplot\bin\libplplotf77cd.dll.a" \ "C:\Program Files\plplot\bin\libplplotd.dll.a" ________________________________________________ and here's the result: _____________________________________________________ E:\Workspace\temp\plplot>gcc -o x01f.exe x01f.f \ C:\MinGW\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: \: No such file: No such file or directory collect2: ld returned 1 exit status E:\Workspace\temp\plplot>"C:\Program Files\plplot\bin\libplplotf77d.dll.a" \ '"C:\Program Files\plplot\bin\libplplotf77d.dll.a"' is not recognized as an inte rnal or external command, operable program or batch file. E:\Workspace\temp\plplot>"C:\Program Files\plplot\bin\libplplotf77cd.dll.a" \ '"C:\Program Files\plplot\bin\libplplotf77cd.dll.a"' is not recognized as an int ernal or external command, operable program or batch file. E:\Workspace\temp\plplot>"C:\Program Files\plplot\bin\libplplotd.dll.a" '"C:\Program Files\plplot\bin\libplplotd.dll.a"' is not recognized as an interna l or external command, operable program or batch file. ___________________________________________________________ It looks like it does not find ld.exe I've got it in my c:\MinGW\Bin. Should I specify that path? Could you help me building this source? Thanks Vince
