PHP for android

1. Get toolchains from CodeSourcery (Choose ARM GNU/Linux and IA32 GNU/Linux).

2. Get php last php source code.

3. Unpack php, run ./configure --disable-all

4. Now you have to patch PHP Makefile, libtool and zend_float.h.
Please make sure you changing the /home/git/arm-2009q3/ to the CodeSourcery location):
(Sorry for the the hacks, i'm sure someone can use the ./configure to make it "the proper way")
