PHP5 on Cygwin ain’t working for me

php-logo.gif I’m trying to get PHP 5.0.0-dev to work under Cygwin. It hasn’t been much fun so far.

I’m working with George on a non-Yahoo! project, so I’ve gotta get PHP installed on a computer that I can use at home. So I figured I’d just build it our Windows 2000 laptop under Cygwin. Should be a piece of cake, right?

Last week I got PHP-4.3.1 running without much trouble. The only snag I ran into involved some mangling of the symbols in the xml (expat) extension. The workaround was to use the Cgywin installer to install a system (shared object) version of expat, then build PHP4 with ./configure --with-expat-dir=/usr instead statically linking in the bundled expat. It worked correctly as both a command-line binary and also when patched into the thttpd web server.

However, it turns out that George is using PHP 5, so I’ve gotta use the same thing. After a busy week last week, I finally got around to fetching the PHP5 source from CVS and started building it tonight.

First I had to install the Cygwin ports of the GNU build toolchain (autoconf, automake, libtool). Piece of cake. Then, much to my surprise, I got the thing to build with a simple ./buildconf && ./configure --with-expat-dir=/usr && make. But that’s when my luck ended:

radwin@radwin /usr/src/php-dev/php5

$ ./sapi/cli/php.exe -v

Segmentation fault (core dumped)

radwin@radwin /usr/src/php-dev/php5


Investigating in gdb (after I installed the Cygwin port), I found this:

(gdb) bt

Bleh. A core in memcpy()? Something’s messed up. I hate it when this happens.

For kicks, I tried checking out the tree with the PHP_5_0_dev_before_13561_fix tag, on the hunch that if someone bothered to tag the tree at some point, it probably worked that day. No luck; it dumps core in the same place.

I’m sure this would all be soooooo easy if I had a Linux box.

  1. Just a note that cygwin really isn’t a target environment for PHP. If you got 4.3.1 to build – great. You’re better sticking with Microsoft’s VisualStudio environment to build windows packages. Or, of course, you could vmware linux, dual boot the system, or get a cheap, $199 crap computer and run it with linux.

  2. The folks at the IS dept have promised (in advanced) to re-image my hard disk if they discover that I’ve installed a dual boot system. Ain’t that generous of them?

    In any case, I’ll probably get a cheapo Linux box at Wal-Mart instead of installing it on my work laptop (and disabling LANDesk). Ariella has been wanting to play with Linux in her spare time, and it makes sense to use a non-company computer for non-company business.
