Hi folks Looks like I'm answering my own question, in part because I did not RTFM until after asking. I apologise for this all too common peccadillo.
This was a no brainer. My libc is older than Blackdown jdk 1.2.2 wants. Quoting from one of the README files: This is the Blackdown Java-Linux port of the Java 2 SDK Version 1.2.2 Release Candidate 3. [snip] Also note that this version needs at least a glibc-2.1.2 based system with a recent 2.2.xx kernel. This build will not run with glibc-2.0 or glibc-2.1[.1]. The final release may come with builds for older glibc versions, but the supported version will be based on glibc-2.1.2 or higher. Apparently, I have glibc-2.0.7 So I have two questions: 1) Can I safely upgrade to libc-2.1.2 without going all the way to Potato? Please point me to the FM on this topic. 2) Is there a JDK 1.2 version that runs under Slink? Would one of you who said you just untarred the tar ball and set the path to get the jdk to work -- Please tell me your versions of libc and of jkd you are using? --David David Teague, [EMAIL PROTECTED] Debian GNU/Linux Because software support is free, timely, useful, technically accurate, and friendly.
