This is one of the errors that I get when I launch php
command in my Windows prompt.
I've installed the environment through EasyPHP 12.1 installer. This is a minor problem, since i can use without any problem the full LAMP stack.
I noticed the problem just because ApiGen needs mbstring
to create documentation (picture above actually is related to bz2 library, but nothing changes for other missing library). Last path in the warning sounds strange since don't exist nothing PHP related in my LaTex distribution. Any suggest about the problem???
