From: starksb@ebi.ac.uk (David Starks-Browning) Newsgroups: comp.parallel.pvm Subject: 64-bit compile on Solaris 7 (and 32/64-bit libraries in general) Date: Thu, 22 Jul 1999 14:10:06 +0100 Organization: EMBL-EBI Message-Id: Xref: ukc comp.parallel.pvm:8596 Greetings, Someone here has attempted to build 64-bit versions of PVM-3.4 under Solaris 7 (aka SunOS 5.7) using the SUNWspro 5.0 compiler. They encountered some difficulty. Before I investigate further, rule out user error, etc., I wonder if anyone has gone through this excercise already? (Perhaps someone at SunHPC has patches handy.) Our particular need is because we have to link with other 64-bit libraries, which in turn must support "large" files (>2 GB -- not very large!). This also begs a more general question of "augmenting" the choices for $PVM_ARCH. To permit development of both 32-bit and 64-bit PVM programs, is it sensible to introduce, for example, SUN4SOL2_64? And can 64-bit and 32-bit PVM tasks cooperate in the same virtual machine and (more precisely) on the same host? Or, alternatively, should 32-bit and 64-bit versions of PVM be segregated by choice of $PVM_ROOT? (This is a classic advanced topic for PVM, and this ought to be the forum to establish "best practice".) Thanks for your help.
