Re: Global can't find GTAGS in link directory

[Qiang Yu]

Hi Shigio,

Thanks for your help. The export method works.

The reason why I do this is I'm working on the X11 code base which has many
modules. Some of them can be reused but some should be one for each. For

example: the xserver/ is common for every machine, but many DDX drivers are
for dedicated cards. 

I want each module has only one copy on disk and several modules form a 
source tree for a card. So I use link directory like this:

Card1:
/home/yuq/card1/{xserver, card1DDX}
Card2:
/home/yuq/card2{xserver, card2DDX}

xserver/ and card*DDX/ are all symbolic link to their directories. So I can create
gtags on each card directory. It seems the reason why my method doesn't work

is:
$ cd dir3/dir1
$ ls ..
dir1/ dir2/ dir3/

The link directory can't go upwards correctly for global to find gtags. Does this
have solution so that I don't need to switch GTAGSROOT each time when I switch card 

source tree?

Here is another question: can global combine many gtags? For example, create
gtags for xserver once, then for every card's DDX, combine them to form a card source 
tree? So I can just update xserver's gtags once for every card source tree.

Regards,
yuq

Symbolic link is such a thing. Why do you make
tag files at /home/yuq?

Or there is also the following method.

$ export GTAGSROOT=/home/yuq/dir3

Good luck!
