RE: cfexecd segfaults under Solaris 8

[Baker, Darryl]

I'm going to sound a lot like Mark. Are you sure you have the same versions
of the shared libraries on all the machines? Are you relatively current on
you Sun patches? I have 80+ Solaris 8 machines and 40+ Solaris 9 machines,
patched to within 3 months of current, and have no problem with cfexecd. I
did have a SIGSEGV problem with cfenvd when sent a SIGTERM but I
retro-fitted code from the snapshot into 2.1.15 and that went away.

Sut since cfengine uses threads, it can also be a reentrency bug or
something more obscure. But it can be a compiler issue as well:

-My first compile was with gcc 3.0, as that's what was installed on the
system. It would throw a compiler error at cfenvgraph.c
- My last compile was gcc 3.3.2, it compiles without problems, cfagent
runs perfectly, but I have the segfault with cfexec.

Can you tell me what's needed to compile cfengine? What
packages/versions, etc.

I can't believe I'm the only one who has these problems... 

Sorry if it has already been answered, but I spent days on Google, on
the cfengine.org web site, on the cfwiki, and I haven't found anything
on that topic.
