A few questions on the mingw port. - wine-devel

29 Mar 2003


      Hello Everyone,
First I want to thank everyone for the help they have given me in 
dealing with my bad spelling, lack of grammer and not following the 
rules when working to get most of wine built for mingw. I'm trying to do 
a little house keeping with Wine and ReactOS and had a few 
changes/questions that could make my and the ReactOS teams life a little 
easyer with the port.
1. Can we set --disable-win16 CFLAGS=-DWINE_NOWINSOCK" to be default 
when building under Mingw? I tried to write a configure patch for this a 
while back but never could get the bastard to work. Once this option is 
removed all we will be left with is ./configure to configure wine for 
mingw. None of the WINE networking stuff will really work for anyone 
working with mingw and I dont expect that to change anytime soon. 
Without this flag anything that include winsock.h or winsock2.h will 
puke when building on Windows. I know that WINE on linux will need win16 
for a while due to older installers that are 16bit but for the mingw 
port thats kind of not important.
2. Can we set a conditional option to not build winegcc and winewrap? 
These are not needed on Windows as they are only used to port mingw 
applications to winelib. Due to the use of Unixisms in these programs 
(fork, waitpid, etc) they wont build. Now I know we could stub fork and 
wrap waitpid to wait but its kind of pointless and I can see one day 
when someone will ask why these dont work on windows even though we 
build them. IMHO they just shouldnt get built for us.

3. Exclude WINEserver. This is a fun one. I took a look at this a while 
back a was able to get about 80% of it to compile native on windows. 
Before we can even get wineserver to build/link on mingw we still have 
the same problem a cygwin port has and that is what to do with the 
get/set thread_context stuff. Also from all I have read a mingw port 
would require a major redesign because of the signal/pipe usage. I 
looked at porting some of the stuff to windows sockets a while back and 
decided I still cant program well enough and I have more interesting 
things to do like work on ReactOS. =P
4. This may be more a mingw problem rather then something with WINE but 
I figured I would ask while I was making noise. When I try to build the 
regression tests under mingw with gcc-3.x I am getting this error. If I 
dont include wines libmsvcrt.a it goes away. do the exit functions in 
wine and mingws source not agree?

At some point I will do documentation for Mingw on MSYS/Cygwin <g>
