help needed with apache build on FreeBSD (9-ish)

[Julian Elischer]

I've been banging my head agains this for a couple of days now and I'm 
ready to swallow my pride and look for help :-)

For $DAYJOB we have an apache 2.2 installed and for reasons I can't go 
into it can not be done via a port, so We are doing it manually.

The build is done in a chroot, which contains a pretty much standard 
FreeBSD install of vintage 9.0 (ish).
The standard apache build is run in the chroot and if the chroot is on 
an 8.0 based (real) machine is succeeds.
If on the other hand the build is on a 9.1 based or 10.0 based VM. if 
fails with the following error:

gmake[3]: Entering directory 
`/usr/build/buildroot/build/cloudcc/build_x86_64/httpd-2.2.11/srclib/pcre'
gmake[4]: Entering directory 
`/usr/build/buildroot/build/cloudcc/build_x86_64/httpd-2.2.11/srclib/pcre'
libtool --silent --mode=link /usr/bin/gcc   -g -O0 -L/usr/local/lib 
-L/usr/build/buildroot/tools/x86_gcc4.2.4/usr/lib 
-L/usr/build/buildroot/tools/x86_gcc4.2.4/opt/pixel8/lib -o libpcre.la 
-static  maketables.lo get.lo study.lo pcre.lo
libtool: link: unable to infer tagged configuration
libtool: link: specify a tag with `--tag'
gmake[4]: *** [libpcre.la] Error 1
gmake[4]: Leaving directory 
`/usr/build/buildroot/build/cloudcc/build_x86_64/httpd-2.2.11/srclib/pcre'
gmake[3]: *** [install-recursive] Error 1

Now if I go to that directory and run the command EXACTLY as show, I 
do indeed get
that error, but if I run it by hand and as suggested, add "--tag=CC"  
then it succeeds.

to make things more puzzling, the arguments that are run when the same 
chroot is running in an 8.0 system are slightly different.
This also succeeds if I type it in by hand on the 10 based system.

libtool --silent --mode=link /usr/bin/gcc -Wall -Wno-unused-parameter 
-nostdinc -isystem /usr/build/buildroot/tools/x86_gcc4.2.4/us
r/include --sysroot /usr/build/buildroot/tools/x86_gcc4.2.4   -g -O0  
-L/usr/build/buildroot/tools/x86_gcc4.2.4/usr/lib 
-L/usr/build/buildroot/tools/x86_gcc4.2.4/opt/pixel8/lib -o libpcre.la 
-static
maketables.lo get.lo study.lo pcre.lo

I have two questions.

1/ given that apache has a maze of autoconf/libtool/configure files 
all over the place, many of which are autogenerated,
where, in the original distribution would I find a file into which I 
can add the aforementionned --tag argument,
or failing that, is there any environment variable or make argument to 
teh main build of apache that would result in that getting set..

2/ does anyone have any idea why one would fail and the other succeed, 
when it's the same identical chroot (nfs mounted to different 
machines. I have set the UNAME_xxx variables and confirmed that they 
are working. The only environment differences in the chroots are the 
SUDO_USER and USER variables.  (1003 vs 1005)  Does anyone know how to 
find out WHY configure is acting different?  hte config.lo files show 
that configure is deciding the same things, and yet, the command lines 
differ.. the whole -Wall section is missing from the one that fails.
