xulrunner-1.9 build problem on armel

[Dave P. Martin]

Hi,

I'm trying to investigate the performance benefits of enabling the use of
hardware floating point in Firefox (especially xulrunner) on armel
platforms.

firefox-3.0 (3.0.7+nobinonly-0ubuntu1) builds fine with a modified
--enable-optimize= option to add the extra CFLAGS.  However, I run into a
problem when trying to build xulrunner-1.9 (1.9.0.7+nobinonly-0ubuntu1),
complaining that XPTcall is not implemented for the platform.
I'm building natively on a Freescale i.MX51 based board (Babbage) - it's a
Cortex-A8 based plafrorm.

Seek to the end of the attached log for details of the failure.

I notice that the Makefile for the affected code chooses an implementation
based on some variables, including OS_TEST, which is expected to contain
something like "arm" or "sa110", but is in fact being set to the empty
string.  OS_TEST is derived by some route from the gnu-style platform
string, which configure is detecting as armv5l-unknown-linux-gnueabi for the
firefox-3.0 build, but when xulrunner-1.9 is configured, confiure prints out
"checking host system type... Invalid configuration `c-disable-updater':
machine `c-disable' not recognized".

Any idea what is happening here?  It looks like it may be related to the
--disable-updater configure command line option specified in
debian/rules:DEB_CONFIGURE_USER_FLAGS

I'm assuming that this package must have built OK on your armel buildd
boards, otherwise there wouldn't be binary packages available...


Any help would be appreciated.

Cheers
---Dave
