Re: when does gtags generate empty GTAGS, GPATH, GRTAGS？

[liang tang]

By the way, following gtags warning maybe not right. when using some macro definition, such as '#define DATA_NAMESPACE_BEGIN namespace  data {;'  warning such as "missing left '{'" may be found in gtags output.

all the project can be compiled.

I don't think so.

The big project which has a long time develop history may have something gtags cannot generate the right file.  You may see  https://github.com/ludovicchabant/vim-gutentags/issues/225, many people come across this problem, not only me. so I think this is gtags bug.
If some files cannot build gtags file, use '--skip-unreadable  --skip-symlink' cannot work. Now we cannot know why gtags generate empty files.

Why did you find out that the size of the project was the cause?
I think you should start by simplifying the reproduction environment.
How about solving the following warnings first?

> Warning: cannot stat 'abs'. ignored.
> Warning: cannot stat 'lib32_debug'. ignored.
> Warning: cannot stat 'lib32_release'. ignored.
> Warning: cannot stat 'lib64_debug'. ignored.

> Warning: different level before and after #define macro. reseted.

> Warning: failed to parse template

...

I suggest moving this thread to the help mailing list.
