Using a RedHat 6.x distro, I have a lot of things updated: kernel 2.2.19 with reiserfs java 1.2.2 ( Sun and Blackdown ) java 1.3 ( Sun, Blackdown, and IBM ) glibc 2.1.3 binutils 2.9.5 cpp 2.95 gcc 2.95 gcc-c++ 2.95 gcc-java-2.95 qt 2.3 Xfree 4.0.3 kde 2.1 I have upgraded gcc from 2.9.1 ( that came with egcs ) to gcc 2.95 ( from libc6 contrib RPM ) due to a compiler bug that I encounered compiling some apps with "march=i686". I want to upgrade from glibc 2.1 to glibc 2.2. I was wondering what the effect of this would be on the java binaries distributed by blackdown ( since the site only mentioned glibc 2.1.3 ), sun, and IBM. With the exception of installing a new distro, I have not done a major glibc upgrade. So my questions are: 1) Is it safe? Will java ( and other the existing apps ) that were compiled, static or shared, with glibc 2.1 still work with glibc 2.2? The only general information I can find about this is on the link below: http://www.imaxx.net/~thrytis/glibc/glibc-FAQ.html#2.3 ... but it seems that the document is about a move from libc5 to libc6. Is there a more updated version of this doc specifically for a move from glibc 2.1 to glibc 2.2? 2) There are glibc 2.2 RPMs from RedHat's contrib directory. Has anyone with a Redhat 6.x distro tried upgrading glibc with these RPMs? If yes, what were the effects on Java? Any help appreciated, John -- Homepage: http://homepages.tig.com.au/~jmsalvo/ Public Key: http://pgp5.ai.mit.edu:11371/pks/lookup?op=get&search=0x51F47D34 ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
