Re: Problems on Sparc; redhat 5.1
Red Hat 5.1 on Sparc uses glibc, while the JDK-port for sparclinux is built using libc-5 (which was distributed with Red Hat 4.x). I was working on a glibc-port (http://www.sesuadra.org/~jdk), but since JDK 1.2 is due to be out soon, I think it is better to work on a JDK 1.2 port for sparclinux glibc. - Johan Nothing vanishes without a trace
Re: jdk1.1.6 (sparc) dumping core
Concerning the problems with JDK 1.1.6 on sparclinux: The binary in the distribution is built on a libc5-system, while Red Hat 5.2 comes with glibc. If you have the corresponding libs installed on your RH 5.2 system, the thing should work however. JDK 1.2 will be built on a glibc-system, so you probably won't have problems running JDK 1.2. When I ldd the libc5 executable from a glibc-system, I got this: tinukai-johan:/jdklibc/bin/sparc/green_threads> ldd java libjava.so => not found libm.so.5 => /lib/libm.so.5 (0x50003000) libdl.so.1 => /lib/libdl.so.1 (0x5001e000) libawt.so => not found libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4 (0x5003) libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x50051000) libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x500b5000) libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x500db000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x500f4000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x50111000) libc.so.5 => /lib/libc.so.5 (0x501d4000) libc.so.6 => /lib/libc.so.6 (0x502c3000) /lib/ld-linux.so.1 => /lib/ld-linux.so.2 (0x6000) ... and the thing works: tinukai-johan:~/jtest> /jdklibc/bin/java HelloWorld Hello World!

Re: How can I contact the Sparc port developers?
Hi, I do have an old SS5 somewhere that I used for the JDK 1.1 port. I will try to get it over to my place, and give it some upgrades (it might take a while though before I have it here). Can you send me your configuration (glibc-version and kernel)? - Johan === Johan Vos [EMAIL PROTECTED] Sesuad'ra Projects http://www.sesuadra.org On Wed, 3 May 2000, Avi Cherry wrote: > I've had a few problems with the sparc port of the Blackdown > JVM regarding threading issues and the HotSpot JIT.

Any ideas about how to improve this ? Yes, performance can be increased since: 1) there is currently no hotspot in sparc jdk 1.3.0 2) some parts were compiled without optimization in order to bypass a compiler problem. The intention was to go to 1.4 immediately, and to skip improvements on 1.3.0 or 1.3.1.
