All,

I have cross-compiled php-cgi for a MIPS device (mediaplayer), but the
binary is quite large, more than 3MB. I'm using:

./configure --prefix=../result/php-5.3.5 --host=i686-pc-linux-gnu
--target=mipsel-linux-gnu --build=mipsel-linux-gnu --enable-cgi
--disable-all --without-pear --with-config-file-path=/etc/

Which options do I have to reduce size of the binary? E.g. can I
remove the zend engine?

what do you mean by "remove the zend engine"?
zend engine is the core, upon which php is built.

Ah, that explains a lot :-) I thought zend engine is an additional
engine for performance reasons..

Is there any other way to decrease binary size? (workaround is to put
php-cgi on external storage)

php-cgi 5.2.x = ~2.4mb "./configure" without :

For latest 5.3.x it still results in a 3+ MB php-cgi binary.

There are some more swicthes
--disable-all Disable all extensions which are enabled by default

What about "--disable-all" followed by "--enable-feature" for all
you want to have?

The follwoing are not needed in most cases
--disable-ipv6
--disable-posix
--disable-phar
--disable-json

--disable-ipv6 Disable IPv6 support
--disable-libxml Disable LIBXML support
--disable-ctype Disable ctype functions
--disable-inifile DBA: INI support (bundled)
--disable-flatfile DBA: FlatFile support (bundled)
--disable-dom Disable DOM support
--disable-fileinfo Disable fileinfo support
--disable-filter Disable input filter support
--disable-hash Disable hash support
--disable-json Disable JavaScript Object Serialization support
--disable-mbregex MBSTRING: Disable multibyte regex support
--disable-pdo Disable PHP Data Objects support
--disable-phar Disable phar support
--disable-posix Disable POSIX-like functions
--disable-session Disable session support
--disable-simplexml Disable SimpleXML support

I already had --disabled-all. I have now tested with -Os instead of
-O2 which results in a 2.8MB executable. So that helps a bit :-)

2.8M? My php binary with just about everything compiled in is around
1MB. Do this:

file php

See how it says "not stripped" ?

That means you have left all the debugging symbols in. Now do this:

strip php

Then check the file size.

Magic!

Try running `strip` on there to take out the excess symbols.

I'll go through the list of options again and disable everything
possible. I am aware of the fact that you must think that I'm a noob,
which is partly true. I do have some PHP programming experience and
sometimes tried to use a function that was not available because it
was not compiled in. But I just tried to have some really basic
functionality included, I can rebuild again when needed. But still:
thanks for the warning :-)

All,

I have cross-compiled php-cgi for a MIPS device (mediaplayer), but the
binary is quite large, more than 3MB. I'm using:

./configure --prefix=../result/php-5.3.5 --host=i686-pc-linux-gnu
--target=mipsel-linux-gnu --build=mipsel-linux-gnu --enable-cgi
--disable-all --without-pear --with-config-file-path=/etc/

Which options do I have to reduce size of the binary?

Check Makefile and correct cc's -O setting to -Os before compiling. Is
your binary stripped?

you may want to re-generate zend_vm_execute.h
php zend_vm_gen.php --without-specializer
It will save ~300k.

also you may want to try to remove Reflection, SPL and Date extensions and
optimize for size: -O1
instead of performance (-O2)
Don't forget to strip off debug info from the binary.

HI Martin,

Is it only file size you worry about or also memory footprint? I assume it'd also be the latter.
If so, we can share a patch we've worked on which could allow you to reduce the memory footprint at compile time somewhat more (on the expense of performance, ...).
We were going to send it out for review anyway so this could be it :)
