Hi All,
I have been working on getting JavaScriptCore building and running but
trying to use a different setup. My goal, is to get it building on
Windows, either through visual studio or cygwin (or both) using
glib/gobject libs instead of libicuxx libs and without core foundation.
Currently, I have been able to get it pretty far, I've branched my own
projects and vsprops, removed the libicu references and added in the
glib references/includes into the vsprops, defined ENABLE_GLIB_SUPPORT,
removed the icu headers/code files from the vs project file and added in
the glib/gobject ones. I've defined in unicodeglib.h UChar and UChar32
as guint16 and guint32 (not sure what is was before, maybe I just
circled back around). I have also defined JSChar as unsigned short (even
wchar_t), after fixing a few compile errors I've managed to get it to
begin linking, but am stuck on some (probably quite trivial) problems,
build output:

Where wchar_t is specified, in the code those are UChar's, which are not
defined as wchar_t (I have it defined as unsigned shorts, even maybe vsc
is just assuming since it is ushort that it's the same as wchar_t?),
I've been at this for a couple days now trying to figure out why it's
looking for these signatures. I've also tried configuring wchar as
built-in type and not with no difference.
As a side note, which I don't think is related but might be, while
building for vs it seems nmake would hang while generating the
KeywordLookup and RexExJit tables, so I ended up just running those
myself through cygwin (just as DerivedSources.make does) and copy them
over during each clean, a bit wonky but again right now I'm just trying
to see if I can get a viable build going using just glib.
Any help, pointers, etc.. would be appreciated.
Thanks,
-JT
