Description:
------------
Compiling PHP 5.1-dev on Woody:

[Machine is an Pentium-3 running Debian GNU/Linux Woody 3.0r6, plus the backport of the 2.6 kernel from backports.org]

wget http://snaps.php.net/php5-200506170030.tar.bz2
bunzip2 php5-200506170030.tar.bz2
tar xfv php5-200506170030.tar 

# steps for building the standalone PHP executable:
cd php5-200506170030

# configure: 
# Note: need to disable all the xml stuff as wants a quite recent version on libxml that an old debian/woody server install simply doesn't have.
./configure --disable-libxml -disable-dom -disable-simplexml -disable-xml --without-pear

# Now compile:
make clean
make 

# use the recommended php.ini
cp ./php.ini-recommended ./sapi/cli/php.ini

# Finally update ownership to stop "unowned files" error messages:

chown -R root.root ~/tmp/

# Should get a compiled PHP5.1 executable in sapi/cli/php
# Run it:
./sapi/cli/php

Results in a seg fault:

Install gawk for now. (see also bug #32144 which is about to be fixed soon)

[2005-06-18 00:19 UTC] nickj-phpbugs at nickj dot org

That fixed it - Thank you!

I.e., for anyone who experiences the same problem:

ludo:~# dpkg -l | grep awk
ii  mawk           1.3.3-8        a pattern scanning and text processing langu
ludo:~# apt-get install gawk
ludo:~# apt-get remove --purge mawk


Then configure, make clean, make, and then ran without segfault.
