I'm not sure if this mailing list is the correct place to ask for porting help, as it seems to be solely dedicated to improving WINE, but the forums on the web site seem mostly for using WINE to run programs directly, not using it for porting. If there is a better place for this query, please let me know.
So... the wine wrapper seems to run our application GUI just fine, however we need to marry the Win32 GUI code to system-level accesses so that we can port the application to Linux. I was having some luck using version 5.0, but had to do some weird linking shenanigans and using pipes to channel data from the linux side to the windows side and vice versa... it was too cumbersome and slow for our purposes, so we walked away. Hearing of version 6, we thought this new architecture might solve our problems so threw together an exploratory project simply to show that it could work. Unfortunately, I've been having some issues and having a hard time determining where they are.
If I leave out the resources and compile with the -v option, this is the build/linking step (the .onlx is a gcc direct-compiled .o file... I've also tried it as an actual .o file in case that is confusing winebuild... same result.)

So, one of these subprocesses is trying to create a .s file on the way to creating the .o file, and having issues? I note a few problems that seem to exist... one, the folder for the EXE doesn't seem to be getting passed to winebuild (-F winetest.exe instead of -F Debug/winetest.exe) and the -o winetest.exe-61799713.spec.o is similarly not specifying a folder. However adding a Debug in front of them manually doesn't do anything so I don't think that's the basic problem.

winebuild: Unable to create output file 'winetest.exe-61799713.spec-61799cc7.s'
Any ideas on what I'm doing wrong? Bad environmental variables or other flags that need to be added? Attached is a copy of my makefile, designed so that I can pull from multiple source folders, keep track of Win32 vs linux source files, etc. It has various dummy targets to more easily experiment with different things or dump variable lists. Attaching the var_o and tar_c outputs as well, just to demonstrate the input values
I also experimented with trying to do things with gcc and ld, but didn't come across any breakthroughs.
In a similar vein, and probably related, I can't get WRC to work either. If I comment in RCflags to get debug level 31, I get the output in rc_debug31.txt in the same folder as my Makefile (ie. Writable folder)
The error output normally seems pretty non-sensical as the .res file should be an output?
wrc -foDebug/WINETEST.res WINETEST.RC
Error: Could not open Debug/WINETEST.res-61799fb9 for input : Permission denied make: *** [Makefile:144: Debug/WINETEST.res] Error 2
This is a much simpler test program than our actual program to port, and I can't even seem to get this one to compile... it's frustrating. I'd love to be able to use WINE to support Linux servers, etc, but I'm stuck.
Any pointers people could offer would be greatly appreciated.
Thank you, Brent
Hello Brent,
IMHO it would be useful to also have the original testproject and instructions on how you converted with winemaker. That already results in it being broken, correct?

Thanks Fabian,
The project is in the winelib subfolder. The original winemaker output was basically empty (unlike the 5.0 time), so I was creating it myself. Important not to rename cases, etc, in this case as it would end up getting broken when our ancient windows tools updated some files and we need to be able to continually recompile and update.
The linux.c file isn't part of the windows project.. that's what I added after the fact. The other parts compile with visual studio.
Brent

"Unable to create output file" means that we couldn't call fopen() to create the file, or unlink() to remove an existing one. Are you sure that winebuild is being called with the right path? Is there a leftover file with the same name that can't be removed somehow?
