No, I don't have any idea how or if any of this applies to Mandrake 9.

With today's release of Red Hat 8.0 there are significantly excellent changes to Red Hat to make life with multithreaded programs, like AOLserver, more convenient. 1) gcc-3.2 is used exclusively throughout Red Hat 8.0. This means that C89, C99, C++, ANSI C++, and friends will work together in harmony as AOLserver shared objects. Please note that there is an inconsistency in the Red Hat 8.0 release notes that claims that the C++ ABI will change in future releaes, but this directly contradicts the actual GCC 3.2 release notes that state clearly that the C++ ABI will not change in future releases. If you're a C++ head be sure to watch out for this but it's probably as easy as keeping your code easy for other people to recompile. 2) Multithreaded program support is getting better and better! The top and ps commands now only display the main (initial) thread of thread-aware processes. To show all threads, use the command ps -m or type H in top. 3) gdb seems to know what it's doing with multithreaded programs and core dumps--I think the jury is still out on this one. 4) The version of Tcl does not have thread support enabled so AOLserver 3.5 users will need to build their own copy of Tcl with --enable-threads --enable-shared. At runtime, AOLserver at this time does not detect that a proper version of Tcl with threads is installed but it's likely we can do this in a future release for all systems. 5) Long ago the default file descriptor limit on Linux was made configurable even if you don't have a 64-bit system. The default Linux installaion has about three zillion times more file descriptors than even Solaris 9. 6) ns_sendmail will work as long as you use localhost or 127.0.0.1 as your smtphost. Red Hat 8 only listens on localhost for security reasons. 7) OpenSSL should be rebuilt according to the documentation that comes with nsopenssl, otherwise nsopenssl will not recognize it. That's all I can think of right now. In the meantime, download Red Hat 8.0 and tell us what you think! Kris

Compare the patches for each distribution and see what the differences are. Install the .src.rpm, and check the spec file as well as the individual patchsets (found on Red Hat in /usr/src/redhat/SOURCES and /usr/src/redhat/SPECS). Being 100% compatible != having the same kernel patches. As I don't do Mandrake anymore (my having some bad compatibility problems a few cycles back, as well as having a close relationship with Red Hat, as well as maintaining the PostgreSQL RPMset), I can't check the differences myself. -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

Speaking of distributions, SuSE ships AOLserver, but they allways compile it without database support :/ Can you convince them to enable it in the future? Daniël

Here's how my friend Dave explains this: First there was gcc 3.2 release. The docs said C++ ABI will not change, because there were no architectural changes in plan. So it should have been stable. But then they found a couple of bugs in the ABI implementation. Fixing those bugs requires ABI change, so the future version will not be binary compatible with 3.2. And since Red Hat Linux 8.0 was being prepared at the time this defect was known, Red Hat's release notes brought you the latest information. -- Branimir

Some of those features sound a lot like the new Linux Native POSIX Thread Library Red Hat has been working on. But, that was just released as version 0.1 a few weeks ago, so that can't be what Red Hat is shipping in 8.0 just yet... And I think the kernel modifications to support that library are all in the 2.5 series too. So unless Red Hat backported the kernel stuff already, it must be something different. http://openacs.org/bboard/q-and-a-fetch-msg.tcl?msg_id=0006JW http://sources.redhat.com/ml/libc-alpha/2002-09/msg00350.html -- Andrew Piskorski [EMAIL PROTECTED] http://www.piskorski.com

6) ns_sendmail will work as long as you use localhost or 127.0.0.1 as your smtphost. This reminds me, if you have downloaded the latest nsadmin package from www.scriptkitties.com in the last few days, it includes a modified ns_sendmail package. It is much enhanced, but it reverses the from and to args. In retrospect, it was a dumb move but years ago it seemed more logical. Daniel P.
