Java on linux Sparc, is there a light at the end of the tunnel ?
Hi,
I'm trying to run the only 1.4 jdk released for the linux sparc arch.
Unfortunately, the only version available for sparc is the 1.4.1 which
began to broke around the availability of the glibc 2.3.6.
Now, some bug have been filed against this but noone ever responded to
it.
The symptom is a sigsegv in the jvm at certain condition.
So for now, this jvm is broken - is there a workaround ? - .
I would like have some 1.4 running (or even 1.5, let's be fun).
I had a look at the sources and I was able to build them on my x86
machine.
The port seems to be possible. I even think that the blackdown java team
has already done it.
So, I was wondering if it is possible to have a .diff file against the
SUN sources available (without sublicensing) like there was one for the
jdk1.1.8 and jdk1.2.2 or to sub-licence the source just to be able to
regenerate a
workable version for the sparc ports which is lagging behing the i386
and amd64?

According to Jurgen Kreileder, there is one bug left that prevents a release. At this time, no JVM is running on the sparc port because of some changes in the glibc that cause the 1.4.1 (only 1.4 jdm released) to crash on non trivial load. Don't ask me, I don't know how to fix it. The status release is that sparc-linux jvm is dead, as far as I know. Seb -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I have linux on it and plans to keep it like this. I've been bitten by the java JVM 1.4.1b not in shape. I've tried to recompile from JVM 1.2, which went almost to the end (there is some problem with a float to text conversion wich makes the build choke). This one is almost ok. But almost is not ok. I don't know if there are more bugs lurking behing the surface. I've been able to build it because the sources were available. For 1.3, 1.4 and 1.5, the diffs against the source are not even available. Don't know why. Licence didn't changed, and diffs of previous JVM were released, leading me to the conclusion that it was ok to release diffs against the SUN source. The hotspot client and server VM has already been ported on the linux/sparc architecture but noone seems to maintains it anymore. Some people released a beta or some earlier work, but no final version were ever released for arch other than x86 and x86-64. There seems to be lacking some continuity in the blackdown's efforts. However, I'm confident that the efforts needed to reactivate the java port should be minimal. Maybe a refresh build for 1.4.1b to make it work with the new glibc should be enough to have a working port again. At least enough to use J2EE and tomcat (which is the most needed apps on sparc/linux). Look at the BSD effort, they keep the diffs available against all java JVM. This is IMHO the way to go. If we only could have the diffs of the impressive work the blackdown team did, it would be a great step toward a working JVM for sparc.

Diffusion of Blackdown diff ?
Hi, Sun opened the code of the JDK. Could the ports done by blackdown team be incoporated to the JDK ? The developements seems to have stalled (no update since the 2005 year). last port of the linux sparc dates from the 1.4.1. I wouldn't be pleased if all this hard work be lost due to lack of interest and obscure licence agreements. At this time, blackdown is the only one to have a java linux port to the SPARC, ARM, PowerPC and MIPS. There was some difs againts the jdk published on the site but none since the 1.3.1 jdk. Is there any possibility to republish the diffs from the recent jdk ? Is there any possibility to contribute to the openjdk ? Is there someone still reading this ml which seems completely dead now ?
