gpick will not compile -- gets stuck at source/cssparser/css_grammar_wrap.cpp

[thezbyg]

Original issue 29 created by thezbyg on 2011-04-27T13:13:14.000Z:

1. run 'scons' in the gpick hg checkout directory
2. build continues okay until reaching css parsing.

I am using gcc 4.6, scons 2.0.1, flex 2.5.35 on Arch Linux.
I encountered this bug while adding a 'LAB' mixing mode to 'Mix Colors'. It occurs whether or not I have modified any code.

I tried copying in a more recent lempar.c from http://code.google.com/p/lemonbind/source/browse/lempar.c -- That reduces the errors but does not eliminate them

Please post the contents of 'build/source/cssparser/css_grammar.c
' after the compilation fails (using original lempar.c file). I managed to successfully compile using lempar.c from http://code.google.com/p/lemonbind/source/browse/lempar.c, but it would cause segfaults when actually trying to use the generated parser. If you like to try it anyway, I attached the necessary changes.

build/source/cssparser/css_grammar.c is attached (before the below mentioned changes)

Thanks for the patch! It didn't seem to apply (to lempar.c), then I copied the lines into build/source/cssparser/css_grammar.c and then it compiled ok, and I could use the LAB mixing mode :)

What is the status of this?

I attach what, IME, is a working lempar.c.. it seems to contain changes that are the direct inverse of your patch. I realize I've had this sitting in my local clone of gpick for a while now.

Never mind :|
Clearly this is not fixed. I don't really understand exactly what a fix for it would look like.
