Frequentry Asked Questions about GLOBAL.
|
|
|
|
----------------------------------------------------------------------------
|
|
Q1. Htags(1) aborts by short of memory. Why? Any workaround?
|
|
|
|
% htags
|
|
Out of memory!
|
|
% _
|
|
|
|
A1. It seems that Perl4 leaks memory. If you use that version of perl,
|
|
then you had better to use Perl5. This works well.
|
|
|
|
----------------------------------------------------------------------------
|
|
Q2. Global(1) and btreeop(1) sometimes core dumps when using a large tag file.
|
|
Any workaround?
|
|
|
|
A2. Btree(3) core dumps with a certain data set.
|
|
Please apply the patches in this package. See ./dbpatches/README.

Q3. GLOBAL skip some functions.
|
|
For example, GLOBAL skip the function 'func' in this example.
|
|
|
|
#define M(a) static char *string = a;
|
|
|
|
M(a)
|
|
|
|
func() { <= GLOBAL skip func().
|
|
...
|
|
}
|
|
|
|
A3. GLOBAL cannot recognize that pattern, because M(a) seems to be
|
|
a function definition.
|
|
|
|
It should be follows.
|
|
|
|
#define M(a) static char *string = a
|
|
|
|
M(a); <= end with ';'
|
|
|
|
func() {
|
|
...
|
|
}
|
|
|
|
Otherwise, you can tell gtags(1) that by listing the macros in
|
|
'.notfunction' file in current directory.
|
|
|
|
[.notfunction]

Q4. I have set up 'global.conf' to use emacs's ctags command with GLOBAL
|
|
but I cannot use htags.
|
|
|
|
% gtags
|
|
% htags
|
|
htags: GTAGS and GRTAGS not found. Please make them.
|
|
% ls G*
|
|
GPATH GTAGS
|
|
|
|
A4. Emacs's ctags cannot locate function referencies. So, gtags cannot make
|
|
GRTAGS tag file with it. With the result that you cannot use htags and
|
|
global's -r option.
