No, that's what you would expect. The problem is being caused because perl amd mod_perl are being built to be largefile aware, whereas by default Apache is not. By following Doug's instructions to let mod_perl build httpd you are building it with the same flags needed to make perl/modperl largefile aware, so Apache too ends up being largefile aware and all the bits then are in sync. If you use APXS you are building Apache seperately and with the standard config, i.e. not largefile aware, so it breaks. If you want to use APXS you have to build Apache to be largefile aware yourself. On Solaris at least the way to do this is to set CFLAGS='-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64' in your environment before invoking the Apache configure. -- Alan Burlison

can you see if this patch fixes the problem? make sure you let mod_perl
build httpd and pass USE_APACI=1 to Makefile.PL

My apologies for taking so long to reply -- it's been a busy week.

Yes. Using the same Makefile.PL invocation that failed before (see my
previous email), this passes "make test." I haven't tried running it
in my full pseudo-production environment because that also uses mod_ssl,
but the test suite checks out okay.
In hopes that this would fix the APXS build, I tried rebuilding with
that, but whenever the httpd tried to load the php3 or perl module, it
would die in pthread_mutex_lock. This was slightly odd, since php3
would load fine when httpd was statically linked against mod_perl.
For the time being, I'll just roll back to using static mod_perl and
dynamic mod_ssl and php3.

My "solution" to this point (suggested by Dave Mee) is to just use APACI to link mod_perl statically into Apache. It's worked perfectly so far, although it is a bit kludgy. Michael
