Bug 26869 – kvim-6.2.14 build failure

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description dallas.morlock 2003-08-18 10:02:04 UTC]

The latest kvim doesn't compile on my machine. I'm guessing this might be a gcc
2.95 vs. 3.x issue. Does Gentoo still support the old 2.95 compiler?

Reproducible: Always
Steps to Reproduce:
1. emerge kvim
Actual Results:

Reassigning to the KDE folks because I'm sure they have more experience with C++ behavior with gcc-2.95.  Vim proper has no C++ code; this is introduced by the KDE version.

Man, I don't have a good answer to you for this.  It's not that Gentoo doesn't support the 
older gcc, but this particular package looks a little iffy.  You've got a conflict with the alloc 
function in the standard template library.  I can only assume that an upgrade to 3.1 or 3.2 
will help, but I can't make promises.  You may want to see if kvim has dependencies on any 
particular version of gcc.

I talked with the devs in #freehackers, and they posted a patch to kvim-dev. Thanks Mickael!

http://lists.freenux.org/wws/arc/kvim-dev/2003-08/msg00020.html

Edit kvim-6.2.14/src/proto/misc2.pro and change

    char_u *alloc __ARGS((unsigned size));

to

    #ifndef __cplusplus
    char_u *alloc __ARGS((unsigned size));
    #endif

Here's how I tested:

# cd /usr/portage/distfiles
# tar xfj kvim-6.2.14.tar.bz2
# vim kvim-6.2.14/src/proto/misc2.pro  # made change described above
# tar cfj kvim-6.2.14.tar.bz2 kvim-6.2.14

Aron, 
 
Can you apply the patch that's affixed a few comments up?  I don't have kvim on any 
machines so I have no way to test it. 

[Comment 5 Aron Griffis (RETIRED) 2003-08-26 17:02:09 UTC]

Yep, I'll apply the patch (soon)

[Comment 6 Aron Griffis (RETIRED) 2003-09-08 08:18:28 UTC]

Applied the patch, thanks!
