sys/modules Makefile after completing a buildworld. History: The bulk of this code was obtained from NetBSD approximately one year ago (I have taken care to preserve the original NetBSD copyrights and I thank the authors for their work.) At that time, the OSF/1 code was what was left over from their initial bootstrapping off of OSF/1 and did not provide support for executing shared binaries. I have independently added support for shared libraries, and support for some of the more obscure system calls. This code has been available for testing and comment since January of 1999 and running on production machines here at Duke since April. Known working applications include: - Netscape (all versions I've tried) - Mathematica 3.0.2 - Splus 3.4 - ArcInfo 7.1 - Matlab (version unknown) - SimOS - Atom instrumented binaries (built on a real OSF/1 system) Applications which are known not to work: - All applications linking to libmach - Adobe Acrobat (uses libmach) This has been tested with applications running against shared libraries from OSF/1 (aka Tru64) 4.0D and 4.0F.
