subversion with apache integration apr-util issue

I was compiling subversion 1.4.0 to be integrated with apache httpd 2.2.8. Everything went smoothly during the compilation process until I tried to access subversion through http, it shows the error message below everytime and resulted in error 500 in the browser:

[Mon Mar 17 16:04:17 2008] [error] [client 10.225.32.40] Could not fetch resource information. [500, #0][Mon Mar 17 16:04:17 2008] [error] [client 10.225.32.40] Could not open the root of the repository [500, #22][Mon Mar 17 16:04:17 2008] [error] [client 10.225.32.40] Can’t set position pointer in file ‘/path/to/repo/db/revs/11857′: Invalid argument [500, #22

It turns out that subversion linked with a different version of apr-util than apache httpd, see blow:

[user@hostname bin]$ ldd ./httpd grep aprlibaprutil-1.so.0 => /path/to/httpd-2.2.8/lib/libaprutil-1.so.0 (0×00ca0000)libapr-1.so.0 => /path/to/httpd-2.2.8/lib/libapr-1.so.0 (0×0035b000)
[user@hostname bin]$ ldd /path/to/httpd/modules/mod_dav_svn.so grep aprlibaprutil-0.so.0 => /path/to/subversion/lib/libaprutil-0.so.0 (0×00111000)libapr-0.so.0 => /path/to/subversion/lib/libapr-0.so.0 (0×00ca4000)

The reason is that subversion-deps-1.4.0.tar.gz comes with an older version of apr-util than the one in apache httpd 2.2.8.To resolve this issue, simply copy the new version of apr and apr-util source to subversion build directory and recompile:

cp -pR ../httpd-2.2.8/srclib/apr/ apr
cp -pR ../httpd-2.2.8/srclib/apr-util/ apr-util
make clean; ./configure –prefix=/path/to/subversion –with-apxs=/path/to/httpd/bin/apxs ; make ; make install
