Send then to bug-cfengine@gnu.org.

on AIX 4.2

A:

Only AIX 4.3 supports POSIX threads fully. You should compile without thread support.

Q:

One of our Sysadmins has noted a limitation with line length under AIX. I'm not sure how easy it is to fix but it might be worth noting it somewhere in the cfengine docs. It appears that on the AIX machines the maximum line length we can use for cfengine files is defined by the constant YYLMAX which is set to be 200. On the Suns this constant is set to be the same as BUFSIZ which is currently set to be 1024. This manifested itself by very unusual behavior as cfengine variables began to be overwritten when line lengths in the config file exceeded 200 bytes. Peter can attest to this. Be forewarned "keep line lengths in cfengine less than 200 if you want them to work on AIX machines" Moral of the story "AIX users beware" Do you think we could just recompile cfengine and use larger buffer sizes all over, I don't know if this constant is all that should be tweaked or if it is somehow tied into the lexx implementation also, since lexx is used to create the parser for the config files.

A:

This is a problem with lex and yacc, not with cfengine. The variable BUFSIZ is a system quantity, not related to cfengine's internal variable bufsize. I would recommend getting bison and flex and doing away with the old lex and yacc from the system. Michael Lachowski reports that this is also a problem with HPUX 10's lex/yacc.
