GNUstep under mingw

[Fred Kiefer]

I am running GNUstep with mingw and there are a few problems left. First 
you hae to use the cygwin make (/usr/bin/make) otherwise the common.make 
file gives an error as it tests the $PATH variable to include the 
GNUSTEP_SYSTEM_ROOT/Tools directory. For this to work also the 
environment variable GNUSTEP_TARGET_OS has to be set to mingw32, which 
is not mentioned in the README.mingw. You should also download a iconv 
library, gnustep base runs without one, but it will be needed later on. 
(BTW Why do we run without iconv, but need libxml2?)

Even after solving all this there is a problem when compiling the 
Testing code of base:

$ /usr/bin/make

This lloks like we need to export more than just the classes from our 
DLL. Has anybody else faced this problem and how could it be resolved?
