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 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().
...
}
A2. 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]
+---------------
|M
|...
----------------------------------------------------------------------------
Q3. 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
A3. 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.
----------------------------------------------------------------------------
Q4. Everything seems to be ok except the man page, the man program on my
machine does not understand the manual files in GLOBAL
A4. Online manuals in GLOBAL are written with 'mandoc' macro which is a part
of GNU groff package. You can format these manuals by following command
line manually.
% groff -Wall -Tascii -mandoc global.1
If you replace your system's nroff(1) with GNU's one(nroff.sh) then
you can use man(1) to see GLOBAL's online manuals.
----------------------------------------------------------------------------
Q5. I have built GLOBAL in WIN32 environment. But gtags(1) failed by sort
command error.
A5. It seems that MS sort is executed. Please set your path so that unix
sort will be executed.
