Re: Problem running gtags on Drupal

[Shigio YAMAGUCHI]

Hi,

It seems a limit of flex(1). The php parser of gtags(1) uses flex(1).

Please try the following to extend the limit.

[in GLOBAL project]

$ vi libparser/php.c

[libparser/php.c]
+-------------------------------
|#define YY_BUF_SIZE 16384
        |
        v
+-------------------------------
|#define YY_BUF_SIZE 65536

$ sudo make install


To Iwamoto san:

It seems that we can change the limit using the -D option of
the latest flex like this:

        flex -DYY_BUF_SIZE=65536 ...

I would like to change the limit using this option.
How about changing the required version of flex to 2.5.6 or later?
