Re: Subversion on AIX

Alas, we don't have "cc", only "gcc".

I finally got everything to work. I had to fudge the flags a bit. And,
I discovered that it wants a later version of Neon than came with the
Subversion package. (I believe the depedencies came with .28 and
Subversion said it needed .29 as a minimum.)

I had to manually compile zlib and set the --with-zlib= flag. It took
me a while to figure out that this flag isn't suppose to point to the
directory where libz.a exists, but instead points to the directory
that contains both the includes and lib directory where the zlib
headers and library are located.

APR presented another nasty trick. When I compiled APR, it created a
liba*.la files that are actually texts file and contains path
information. Despite compiling APR with the path /home/cmuser/lib, and
the fact that it actually installed there, it had set libdir to
/usr/local/apr/lib. I had to manually change all of these.

So, I now have 1.6.13 working on my AIX 5.3 system, but the http
protocol won't work. If I want that to work, I'll have to download the
latest copy of neon from the Apache neon project and recompile
everything again. Fortunately, we're going to try using svnserve, so
that may not be an issue.

I may have already stated this, but the way the build works really
sucks. Running "configure" on AIX powerpc would take 15 to 30 minutes.
Each time, determining whether my version of sed truncates characters,
the name of my default executable created by the linker, etc. And,
when things didn't work, it took hours to trace where the error was
occurring and why. The "configure" shell script is a very long and
confusing mess with almost no documentation.

I do have my build commands in a shell script in case anyone has to do
this again (I did this when I realized I had to do this over and over
again, and the entire Subversion build takes almost 3 hours to do).

I may try again with the latest Neon if we do need the http protocol.
