#229 Build fails with bison-3.0

[Mike Ressler]

I encountered this build failure on Archlinux with both the xxdiff-4.0 package and the Mercurial version. Things proceed until resParser_yacc.cpp where I get the following message:

resParser.y:41:48: error: ‘resources’ was not declared in this scope

(full build log is attached). If I drop bison back to bison-2.7.1, then the build is successful with only a few warnings.

Are you using bison-3.0?
Bison-3.0 makes %pure_parser obsolete.
I just installed it, and I can reproduce the problem you see, thanks for your detailed report.
I'll try to look at this over the next few weeks; I need to find a solution that works for both 3.0 and 2.7, for many distros.

[Martin Blais]

What version of flex are you using?

[Mike Ressler]

bison-3.0 and flex 2.5.37. Changing only bison allowed me to compile it.

I'm happy to supply any extra information, or to test things when you think you have a solution. I'll try to pay attention here, since I didn't get an email notification that you posted.

Thanks for maintaining a great tool. I consider xxdiff a "must have", so I'm very happy to see that it is still alive.

The attached patch fixes compilation with Bison 3, and should work with Bison 2.x as well (untested)

[Martin Blais]

Fixed by applying other patch.

Hi,

When is this patch going to appear in the source tarball? Alternatively, would you mind posting a link to that "another patch" here?

[Martin Blais]

I'll have to look at this in a week or two, I'm swamped at the moment. The patch also had to be reverted.

[Martin Blais]

I've applied a patch by John Schmerge which makes it build with bison 2 and bison 3. If you run into any problems, let me know.

About the source tarball: I don't release a source tarball anymore. Is that a problem? Can you clone from the default branch in Mercurial instead?
Thanks,
