# php5 for the Blackfin
# David Rowe March 2008
#
# usage: make -f php.mk php-package
#
# Thanks Mike Taht for working out initial Blackfin config, and Astfin
# guys for helping me with sqlite3 support.
#
# Build options have been selected for running FreePBX on the
# Blackfin.
#
# You need to build a bunch of other stuff first, e.g. from a scratch BAPS
# check out:
#
# [baps]$ make -f uClinux.mk && make -f libssl.mk && make -f libiconv.mk
# [baps]$ make -f gettext.mk gettext-package
# [baps]$ make -f sqlite3.mk sqlite3-package
# [baps]$ make -f libxml.mk libxml-package
# [baps]$ make -f php.mk php-package
# Notes:
#
# 1/ Run time memory is still around 6.6M for dynamic linked (e.g. just
# ./php). Would be nice to reduce this....
# 2/ Strip reduced exe size from 8.3M to 2.4M
# 3/ Idea: further weight loss might be possible by looking at
# all the options reported in php_info() and working out
# which ones we can disable at ./configure time.
# 4/ Can php and php-cgi be combined in some way, e.g. via exporting
# some of their functionality to .so's?
