GNU GLOBAL is distributed with a PHP parser generated with an
|
|
old version of flex(1). That parser has some limitation. See:
|
|
http://comments.gmane.org/gmane.comp.gnu.global.bugs/1439
|
|
|
|
Installing GNU GLOBAL with Homebrew will therefor rebuild the
|
|
PHP parser using Mac OS X' newer version of flex(1) which
|
|
generates a parser without the limit.
|
|
|
|
You can install GNU GLOBAL without rebuilding the PHP parser
|
|
(and instead use the parser distributed by GNU GLOBAL) by using
|
|
the option '--without-rebuilding-php-parser':
|
|
|
|
brew install global --without-rebuilding-php-parser
|
|
|
|
Use i.e. if you want to be sure whether a problem is caused by
|
|
the rebuild parser or some other thing in GNU GLOBAL.
