Re: SVN on AIX

Hi all,

I managed to get a build of Subversion that at least lets Apache load the
mod_dav_svn and mod_authz_svn modules. I haven't had time to actually test
it out yet due to other duties but it's at least one more step to building a
proper Subversion server on Apache.

What happened was that I decided to try and build PHP as a shared object and
see if Apache could load that. Well, it could, no problems. One thing I
noticed in the PHP Makefile was a reference to the
${APACHE}/modules/httpd.exp file, which I had wondered about cos Subversion
doesn't seem to make use of it but it obviously pertains to modules. Anyway,
it's a linker flag, which I haven't tracked down yet. In PHP's Makefile:

-Wl,-bI:$(INSTALL_ROOT)/usr/pkg/httpd-2.0.48/modules/httpd.exp -avoid-version

So in Subversion's edited Makefile:

LDFLAGS = -Wl,-brtl
-Wl,-bI:$(INSTALL_ROOT)/usr/pkg/httpd-2.0.48/modules/httpd.exp -avoid-version
-module -L/usr/pkg/db-4.2.52/lib
-L/usr/pkg/src/subversion-0.37.0/apr-util/xml/expat/lib $(EXTRA_LDFLAGS)

The "avoid-version" and "module" flags I added for good measure. I'm ashamed
to say I don't know what they mean but will be tracking them down when I get
a chance.

At any rate, I hope if somebody tries to build SVN on AIX, this helps them out
a bit! Thanks to Travis P for doing previous work in getting the client to
work. :)
