Right... I was thinking about /usr/lib/libast.so.1 + /usr/lib/64/libast.so.1 shipped with Solaris 11 (which was added as part of the ksh93-integration project (and now moves over to the POSIX commands community)) ... > It seems that there is an unfortunate > confluence of library names. This is likely to cause problems. Umpf... libast.so.1's name has at least precedent down to 1992 or earlier (and AT&T owns a trademark for "AST", too). > Is there an easy way to get the AT&T Software Technology (AST) library > downloaded and built to run on Solaris 10? Uhm... yes... you could build it "manually" as described at http://www.research.att.com/sw/download/ but that does not mangle the symbol names as defined by PSARC/2006/550&co. ... ... but there is a script we use to generate the includes for OS/Net which does the task nearly 80% complete (still lacking all optimisations done within OS/Net) - see http://svn.genunix.org/repos/on/branches/ksh93/gisburn/prototype021/usr/src/lib/libshell/misc/buildksh93.sh and http://svn.genunix.org/repos/on/branches/ksh93/gisburn/prototype021/usr/src/lib/libshell/misc/buildksh93.readme for a small description how to use it (for Solaris 10 you may need to add "-lrt" to the link flags (and note that you shouldn't install libcmd.so.1 generated by that build on a Solaris 10 machine)). ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.ma...@nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;) _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
