RE: Assertion failed: __objc_class_hash with Swarm 2.2 snapshot

[Vidrine II,C. Kent]

I have access to gcc via NFS mount to a system that I don't control, so I
didn't apply the gcc patch. In the article at
http://www.santafe.edu/projects/swarm/archive/list-archive.0112/0083.html,
Marcus Daniels states that there is a workaround. I used that workaround
(commenting a line out in one file followed by a complete build) instead of
applying the gcc patch. Is the approach that I took problematic?

Also, I used Sun's Java environment rather than Jikes.

Do you believe that the build process is sensitive enough to the differences
(Sun's Java vs Jikes, hdf5 1.4.4 vs 1.4.3) that it would cause the
initialization failure that I'm seeing?

Hm.  I don't do Solaris, but:

Swarm as distributed should not compile with stock gcc-3.0.2.   You can
search back in swarm-support about 3 months for a message from me
explaining the need to patch gcc in order to compile Swarm as distributed.

Can you tell us if Objective-C programs like Heatbugs works?

On the Java side, we have much better luck with jikes as the java
compiler.  You don't say if you used that or not.

I've not built swarm with hdf5-1.4.4. The newest I've done is 1.4.3
