Bug 342817 – dev-tex/catdvi-0.14 does not compile with dev-libs/kpathsea-6.0.0_p20100722

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Martin Väth 2010-10-26 19:33:23 UTC]

Apparently, the type of kpathsea_version_string has changed from char *
to const char *
Hence, catdvi will not compile with >=kpathsea-6
I attach a trivial patch which fixes the problem

Fix to change type of kpathsea_version_string

[Comment 2 Ulrich Müller 2010-10-26 20:34:40 UTC]

Unfortunately, your patch breaks compilation with app-text/texlive-core-2009-r2:

gcc -O -march=core2 -ggdb -O2 -pipe  -DCFG_HAS_GETOPT_LONG  -c -o kpathsea.o kpathsea.c
kpathsea.c: In function ‘version_findtfm’:
kpathsea.c:39: error: conflicting types for ‘kpathsea_version_string’
/usr/include/kpathsea/version.h:24: note: previous declaration of ‘kpathsea_version_string’ was here
make: *** [kpathsea.o] Error 1
make: *** Waiting for unfinished jobs....

Variable kpathsea_version_string should be declared in kpathsea header files, so I believe that we can simply remove the declaration.

Does attached patch fix the problem for you?

[Comment 4 Martin Väth 2010-10-27 21:07:54 UTC]

Yes, it works. It is clearly the better solution.

[Comment 5 Ulrich Müller 2010-10-27 21:56:43 UTC]

Fixed in -r1. Thank you for reporting and for pinpointing the problem.

iirc kpathsea/version.h wasn't available with kpathsea versions prior to texlive 2008 (or was it 2007?) and kpathsea_version_string wasn't declared in any header. That's why I used such a patch instead:
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-libs/freetype/files/freetype-1.4_pre20080316-kpathsea_version.patch?revision=1.1&view=markup


if its already included unconditionaly then it's good to remove the extra define though.

[Comment 7 Ulrich Müller 2010-10-28 05:53:41 UTC]

Thanks for this info. It is included from kpathsea.h, but only in TL 2009. So I guess we have to detect version.h in configure and explicitly include it.

[Comment 8 Ulrich Müller 2010-10-28 16:47:48 UTC]

Fixed again, thanks Alexis. (The build system of this package is strange, by the way.)

@Martin: Could you report this bug upstream, too? There's not much activity, but I think it should be done anyway.
