[users@httpd] Apache 2.2.10 - apxs - cross-compiling modules failing
Short: I need to cross-compile modules which use apxs, but apxs fails.
Long: I've tried the mod_python list, since that's the list dealing
with my problem module, however after a few rounds of emails, it
became apparent that the problem seems to be with the fact that there
isn't a version of apxs that can be used during cross-compiles.
Either:
1) The host version (if it even exists!) could be used, in which case
the resultant module is likely unsuitable for the target platform or
2) The target version could be used, but that tries to use files that
aren't (yet) in their correct place, since it's being executed from
the host.
Is there some magic I need to be able to cross-compile modules that
require apxs, or a page describing what I need to do that Google
hasn't yet thrown at me? Searches for 'cross-platform apxs' and
'cross-compile apxs' haven't been too illuminating.
TIA.

I haven't tried too many external apache modules, but cross-compiling
mod_python is certainly difficult. It tries to run apache to
determine its version, and the same with python. There's no way to
set an 'ac_cv_foo' variable to override this step. This part is
easily patched in mod_python's configure (just remove the tests if
you're certain your apache/python are version 2), but it doesn't stop
there.
The cross-apache's apxs doesn't run very well on the build host (stuff
generally isn't installed on host where it'll end up on target, etc),
so when mod_python wants to run apxs to build and link the .so, it
fails.
I got somewhat further along by changing $(APXS) to $(CC) (and fixing
up some flags) in src/Makefile.in, but when it came to the 'dist'
subdirectory, I gave up. The makefile requires PYTHON_BIN to do a lot
of compiling, and it also builds C files seemingly without looking at
$(CC) (but rather $(APXS)).

Because there is (currently) no evidence when trying to compile
modules. Apache cross compiles fine. It's the associated tools
supplied with the apache build to build cross-compiled _modules_ I'm
having problems with.
And as the logs show, the configure doesn't get very far since the
target version of apxs (part of apache) isn't compatible with the
cross-compilation procedure, so it doesn't even get as far as calling
any version of apache, cross-compiled or not (either of which would be
invalid in a cross compilation environment.)
Basically there are three 'sets' of programs used/created when cross compiling
1) Host executables
2) Cross-compiler executables
3) Target executables.
(1) are used to make (2) that are then used to make (3)
The apache build does not appear to produce any in group (2) even
though they are needed when cross compiling (Specifically apxs (so
far) in my example.)

Appropriate configure options or hints would be nice. Which --options
do I need to set?

No - I need ./configure options. This happens before 'make install'.
The makefile is generated from configure.
If I'm abjectly wrong here, I apologise, but my problems start before
even attempting 'make build'

If the copy/paste didn't make it clear enough, there are two versions
of apxs to choose from,
1) the host one. (here)
2) the target one. (there)
Both refer to their own 'local' one.
Cross compilation requires a third one: 'run here, but act as if
you're running there.'
How do I (a) generate this third version (b) refer to it when compiling.
I'll still admit ignorance in this, and ask, 'am I still on the right
list here?'
Am I?

Exactly. You'll need to "make install" the cross-compiled apache
to get an apxs that'll pick up the right tools and options.
You may find you need some dependencies cross-compiled too.

You told configure that a valid version of apxs was
at /f15/usr/local/bin/apxs.
apxs is just a perl script that explains how to build apache modules. If
you look at it, the first thing it does is to include the file
$installbuilddir/config_vars.mk. As you can see from the output of
running it, it tries to include /usr/local/conf/build/config_vars.mk,
which obviously is not where it is.
apxs has its installbuilddir calculated when the apache binaries it
accompanies are compiled and installed. Since yours doesn't look in the
right place, I'm guessing your cross built apache was not
installed/configured correctly.

Copy/paste from the mod_python list from my initial stab at finding a solution:
Version of mod_python: 3.3.1
Apache: 2.2.10
Python: 2.4.4 (I realise this is an old version, but this was
requested due to compatibility issues with other software that's
used.)

Dunno, I've not tried it.
How about telling us what happened when you just tried using
the apxs from a build cross-compiled for your target platform?
