Hi folks,
Here is the first cut at winewrap, as described here:
http://www.dssd.ca/wine/Winelib-Apps.html
What it does at the moment:
-- invokes winebuild to create the .spec.c file
-- compiles the .spec.s file
-- links in everything, and generates the .exe.so file
What remains to be done:
-- generate the actual executable.
One possible option is to modify wineapploader so we
simply symlink to it. I have a version of this around.
Is this acceptable?
Comments welcomes.
