Hello,
Please see the second EXAMPLES section of gtags(1).
However, you must set ctagscom variable to uctags path like this:
[/usr/local/share/gtags/gtags.conf]
+----------------------------------------------------------------
|...
|universal-ctags|setting to use Universal Ctags plug-in parser:\
| :tc=common:\
| :ctagscom=/usr/local/bin/u-ctags:\ <=== Please
set uctags path.
| :ctagslib=$libdir/gtags/universal-ctags.la:\
|...
$ GTAGSCONF=/usr/local/share/gtags/gtags.conf
$ GTAGSLABEL=universal-ctags
$ gtags
$ global -x '.*'
Bar 3 Bar.cs public class Bar : IBar
Common.Services 1 Bar.cs namespace Common.Services
Common.Services 4 IBar.cs namespace Common.Services
Common.Services 1 Program.cs namespace Common.Services
Hukarz 5 Bar.cs public void Hukarz()
Hukarz 8 IBar.cs public void Hukarz();
IBar 6 IBar.cs interface IBar
Main 5 Program.cs public static void Main()
Tester 3 Program.cs public class Tester
$ _
Good luck!
