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
