Problem with compilation due to another copy of mingw on my computer

[Alexander L]

Greetings all,

I'm new to gfortran compiler, and have a problem.
I've installed gfortran compiler and when I compile a Fortran source file with a command like

gfortran D:\f90\test.f90  -o D:\f90\test.exe ,

I receive error message:

E:\Haskell Platform\2014.2.0.0\mingw\bin/ld.exe: unrecognized option '-plugin'
E:\Haskell Platform\2014.2.0.0\mingw\bin/ld.exe: use the --help option for usage
 information
collect2.exe: error: ld returned 1 exit status

I have Haskell platform on disc E. If I temporarily change Haskell platform's folder name, my file compiles without errors. But when I run the executable file, I receive error message that file "libgcc_s_dw2-1.dll" is not found. This file is both in gfortran's directory and in Haskell's. Is there any way to solve this problem?


Thanks in advance.
