Hi:
I have strange behavior that I can't resolve. I am on ubuntu 14.04 64
bit. I downloaded global-6.5 and did:
./configure --with-exuberant-ctags=/usr/bin/ctags-exuberant
--disable-gtagscscope --prefix=/usr
"make" and "make check" all pass.
I did a "make install" as root. I then use the following C++ code and
generated tags via "gtags" command.
ubuntu-14-64bits> cat -n foo.cc
1 #include <map>
2
3 typedef int DomainId_t;
4
5 typedef std::map<DomainId_t, int> map_t2;
6
7 main(){
8 DomainId_t foo1;
9 map_t2 mymap;
10
11
12 }
When I then use global to find definitions
ubuntu-14-64bits> global -v --result=grep --nearness
--path-style=shorter DomainId_t
foo.cc:3:typedef int DomainId_t;
foo.cc:5:typedef std::map<DomainId_t, int> map_t2; #
<<< UNEXPECTED
2 objects located (using '/home/gthaker/t2/GTAGS').
I don't understand why it also returns foo.cc:5 entry. (Makes no
difference if I use "-d" option.)
I have been chasing this for a few days. I have narrowed this down to
"gtags" command, since if I generate GTAGS (and GPATH and GRTAGS) on a
different machine where I have built global-6.5 earlier I get correct
behavior. (So it is not "global", but GTAGS generated by gtags.)
I have:
ubuntu-14-64bits> /usr/bin/gtags --version
gtags (GNU GLOBAL) 6.5

Interestingly, on a MINT system where proper GTAGS* files get generated
I see:

DomainId_t
foo.cc:3:typedef int DomainId_t;
1 object located (using '/home/gthaker/t2/GTAGS'). # OK, OK, OK
Naturally code snippet I am using is for demonstration only, the actual
code where I see this is a large piece of (open source) software, and
not being able to natigate around has given me a lot of trouble.
Appreciate any pointers.
