undefined reference to `_imp__NimMain'

[retsyo]

I am using msys2+mingw32 on Win7 64 bits. I modified pmgen.py (https://github.com/retsyo/nim-pymod/blob/master/pmgen.py) in 2 aspects

1. use raw string in nim.cfg and pmgenSRC_incl.nim so that r"r:\someplace" for nim on windows is a valid pathname
2. judge getvar('LIBS') which can solve the problem in https://github.com/jboy/nim-pymod/issues/5

however, during compiling

Caught OSError([Error 2] ) Traceback (most recent call last): File "E:/msys64/home/LOVLJIDY/_nim/nim-pymod/pmgen.py", line 538, in main() File "E:/msys64/home/LOVLJIDY/_nim/nim-pymod/pmgen.py", line 173, in main nim_modfiles, pminc_basename, python_exe_name) File "E:/msys64/home/LOVLJIDY/_nim/nim-pymod/pmgen.py", line 400, in compile_generated_nim_wrappers subprocess.check_call(make_command) File "E:\prg\py\Anaconda2_32\lib\subprocess.py", line 541, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['make', '-f', 'Makefile']' returned non-zero exit status 2

I traced it down by
