Re: linking probs with ccext2 and cmdlineopt using w32 msys/mingw

[Wolfgang Alper]

Well after a while i found the problem.
it is really trival if one knows about it.

the point is the order of commands in the make file (refering to the process 
of linking)

Example1: given that  c++ = mingw32-c++
(does NOT work on win32(mingw/msys) and cause the linkage problem, but works 
on linux)
c++  -L/mingw/lib -lccgnu2 -lccext2 -lws2_32  cmdlineopt.o  -o cmdlineopt.exe 

Example2: given that c++ = g++
(this DOES work on both win32 and linux)
c++  cmdlineopt.o  -L/mingw/lib -lccgnu2 -lccext2 -lws2_32  -o cmdlineopt.exe 

hope that helps those haveing probs when porting from linux to mingw/win32

Regards

Wolfgang

p.s. it someone is interested , i would put together a simple summary of what 
i changed for:

-getting commonc++ compiled on win32(using mingw/msys)
-changing mingw (libs /include) on win32  to get other apps compiled outside 
the commonc++ src dir.
-creating a makefile for a 3th party up to work with mingw/msys and commonc.

it might be that i did things that i should not have done. but as i stated 
before, these were my first steps on win32 mingw/msys and now i can compile 
the same source from the same dir for both linux and w32 :-)
