Re: [Tinycc-devel] tcc port to cygwin

Gives me the clue that the problem may be in the parsing rather the pp stuff.
The output when PARSE_DEBUG is set definitely shows the problem area.
Maybe someone more knowledgeable can figure this out.  Unfortunately, I've
used up my available tcc debug time for the week.  I did manage to port COS
to build on cygwin and am starting on some of the PDL Next Gen stuff there.

The connection with tcc is that I would like to use it to JIT so that the COS/C
stuff can be updated at runtime for dynamic operation---such as applying a
computational role to a pdl operation.

Hi David-

Ack!  I was only looking at the tccpp.c since the problem was with the includes.

I think if you select the Devel all you'll get alot of things which should be enough.
Off the top of my head, the specifics would be gmake/make, gcc, and maybe git + your choice of editor.
Sorry I can't be more specific but the cygwin setup.exe is not really easy to determine what is needed.
In the past, when I've had problems, I search for the problem file or whatever using this page:


Then you install and iterate until things work.  Unfortunately, I would help you with this but
the cygwin setup program is too smart for me to make it think I'm doing a clean install.
If you determine the needed packages, that would be great to know---personally and for
any potential Alien::TCC stuff on cygwin.

Hello Chris,

According to ack, "skip(')')" shows up all over the place in tccgen.c. What does line 196 of your sys/reent.h look like?

Also, if I started from a pristine Windows installation with a core Cygwin installation, which Cygwin packages would I need to install to get to where you are?

Atttached is a first cut port of the TinyCC build to the cygwin platform.

The mains problems seem to be from managing the different include files.
I hand added some defines to libtcc1.c for __INTPTR_TYPE__ and a few
others to get that to build.

However, it is now failing to build bcheck.c with:

Looking at the origin of the error message in the skip() routine
in tccpp.c, I could not find any place that skip() was called with
an argument of ')'.  Is there some other place that message
could be coming from.  Seems like it might be a possible
problem in the preprocessing....
