Bug 153712 – Kdevelop 3.3.5 requires ctags 5.6

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Paulo J. Matos 2006-11-01 10:08:19 UTC]

kdevelop 3.3.5 requires ctags 5.6. 
Trying to build a ctags database for a C++ project I get from kdevelop: ctags -R --c++-types=+px --excmd=pattern --exclude=Makefile --exclude=.
ctags: unrecognized option `--c++-types=+px`

seems that --c++-types is a 5.6 flag.

Problem is that there's no ebuild yet for 5.6! :-/

Yeah, this is totally retarded.

It is caused by kdevelop hard-coding the binary "ctags".  However, that points to(at least on my system) a ctags from the Emacs package...

root@willbtop ctags2 :) $ equery belongs ctags
[ Searching for file(s) ctags in *... ]
app-editors/xemacs-21.4.17 (/usr/bin/ctags)

Whereas, the file I want is "exuberant-ctags", that belongs to the "ctags" package:

root@willbtop ctags2 :) $ equery files ctags
[ Searching for packages matching ctags... ]
* Contents of dev-util/ctags-5.5.4-r2:
/usr
/usr/bin
/usr/bin/exuberant-ctags

Problem is... There is no "configuration" method I have found of telling kdevelop to use "exuberant-ctags" instead of "ctags".  This breaks code complete on my version also (kdevelop-3.3.2).

But a patch can be had... The file ctags2_part.cpp in the kdevelop project can be patched like so:

        QString argsDefault = "-R --c++-types=+px --excmd=pattern --exclude=Makefile --exclude=.";

And added to the kdevelop-ebuild-dohicky.

Actually, that is a lousy way of doing it (too much burn out)... How about this instead:

Will fix in 3.4.0.

Fixed in 3.4.0, the default for new installs will be exuberant-ctags.
