I'm installing OpenACS 4.6.3 and initial attempts to start AOLserver fail when trying to load the nssha1.so module.
nssock.so and nslog.so load successfully and then this:
[04/Sep/2003:21:18:20][32196.16384][-main-] Warning: modload: failed to load '/usr/local/aolserver/bin/nssha1.so': '/usr/local/aolserver/lib/libnsd.so: undefined symbol: Tcl_GetMemoryInfo'
[04/Sep/2003:21:18:20][32196.16384][-main-] Fatal: modload: failed to load module '/usr/local/aolserver/bin/nssha1.so'
How to fix?
