Subversion 1.6.2 runtime error on network access on OS X 10.5

A new SelfSolved solution is up for perusal. The problem I tried to solve:

After compiling Subversion 1.6.2 from source on OS X 10.5 Leopard, the compilation is apparently successful, but svn dies when it tries to connect to the network for the first time. Crash log reports that symbols are missing from libneon.dylib.

Crash report from shell:

dyld: lazy symbol binding failed: Symbol not found: _ne_set_connect_timeout
Referenced from: /usr/local/lib/libsvn_ra_neon-1.0.dylib
Expected in: dynamic lookup

dyld: Symbol not found: _ne_set_connect_timeout
Referenced from: /usr/local/lib/libsvn_ra_neon-1.0.dylib
Expected in: dynamic lookup

Check out the places that I googled and my final solution writeup … at SelfSolved #49: Subversion 1.6.2 explodes on first network access.

The problem is very similar to a previous compilation issue I solved for PHP. In essence, the -L library search path passed to GCC at compilation time has /usr/lib in front of everything else. This means whatever library path you might have given to it at configure time, it’ll always look for the library in /usr/lib first, picking up the old system libneon in the process. Since the bad libneon dynamically linked, the problem doesn’t manifest itself until runtime — and only at runtime with network access involved.

As with the PHP issue, change the very first -L/usr/lib to -L/usr/local/lib (or wherever your newer libneon is located), and it’ll link correctly.

Out of curiosity, I checked MacPorts first. The MacPorts solution of disabling libneon version checking is odd — it also works, but I dunno if it’s linking to the right thing or not.
