I'm trying to create a DLL from a script and a matching wrapper (I need to use the DLL inside LabView so I have to adapt function parameters).

When I try to compile the wrapper:

mbuild -v A0007121_3LIV_W.c A0007121_3LIV.lib LINKFLAGS="$LINKFLAGS /DLL /DEF:A0007121_3LIV_W.def" LDEXT=".dll" CMDLINE250="mt -outputresource:$EXE';'2 -manifest $MANIFEST"

I got this:

Verbose mode is on.
... Looking for compiler 'MinGW64 Compiler (C)' ...
    ... Looking for environment variable 'MW_MINGW64_LOC' ...Yes ('C:\mingw64').
    ... Looking for file 'C:\mingw64\bin\gcc.exe' ...Yes.
    ... Looking for folder 'C:\mingw64' ...Yes.
