Re: [Tinycc-devel] tcc port to cygwin

2016-05-22 Thread Chris Marshall

First, I would like to apologize for my random speculation that the 
bcheck.c compile problems from my posix cygwin port was a possible bug 
in tcc.  Now that I'm further up the learning curve on tcc/compiling I 
think the most likely issue is include file compatability which results 
in invalid code getting to the tcc parsing routines.  I did not mean to 
insult the active development effort that continues to improve tcc 
features and performance.

Second, what would be the best way (when, where, how...) to get the 
cygwin work into tcc upstream?  I've sort of assumed that the mob branch 
is the true master from the activity on the mailing list.  Is that 
true?  In the meantime, I plan to set up a mirror on my github so that I 
can stand up a separate branch for the cygwin work for other developers 
to access in the meantime.

Third, any suggestions on how to diagnose and debug the problems of the 
cygwin system includes for gcc to use as simply as possible with tcc 
compilation?

port COS
to build on cygwin and am starting on some of the PDL Next Gen stuff

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.

I think if you select the Devel all you'll get alot of things

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:

https://cygwin.com/cgi-bin2/package-grep.cgi

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.

Looking at the origin of the error message in the skip()

in tccpp.c, I could not find any place that skip() was

an argument of ')'.  Is there some other place that message

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?

[Tinycc-devel] tcc port to cygwin

2016-05-20 Thread Chris Marshall


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:

-Wno-unused-result -Wno-uninitialized -fno-strict-aliasing -fPIC

Subject: [PATCH] Basic port to cygwin of mob tcc

The remaining issues appear to be ones relating to include file
problems.  Specifically, the local include/stddef.h and others
seem to be inconsistent with those from the native gcc (as in
/usr/lib/gcc/x86_64-pc-cygwin/4.9.3/include/stddef.h or others.
