Olaf,
Apologies to all if this has already been dealt with...
I found that in order to get Maxlib (from a fairly recent CVS download) to compile in Linux with Pd .38testXX I had to delete lines 27 and 29 in the files netclient.c, netrec.c, and netserver.c.
I assume that maybe the "PD_MINOR_VERSION==37" should actually be a ">=".
I have no idea though, I don't actually know what I'm doing. I just guessed that deleting those lines would fix something... :-/
Cheers, David
