FreeBSD and Qt-Jambi
Message 1 in thread
Hello,
I have been waiting a long time for this release and it is wonderful. I am
very impressed (I've used it on Windows) however I have tried to run it on
FreeBSD with little success, here is a record of my attempts:
My first attempt was with a natively build JDK. This version of java works
well however when running the demo ./qtjambi.sh the vm exits with the
problem:
failed to load library: 'qtjambi'
Exception in thread "main"
java.lang.UnsatisfiedLinkError: /usr/home/DragonSA/src/qtjambi-linux-preview/lib/libqtjambi.so.1.0.0: ./lib/libQtCore.so.4:

I have tried copying libraries around and forcing the loading of libc from the
linux version (ABI) but doing so breaks every program on FreeBSD, the two
libc are not compatible and I am unable to get the Qt*.so.4 libraries to
exclusively use the linux version and at the same time let FreeBSD programs
(java) use the FreeBSD version.
My second attempt was greeted with a little more success. I got the libraries
to load and the first screen of the demo. For this I used the linux version
of the JDK, however there was a conflict with the libgcc_s not being new
enough (3.0 instead of 3.3), that was easily solved with a rpm from
FedoraCore 3: gcc3.4.4. After that the vm crashed just after loading (no
display) so I appended "-XstartOnFirstThread" to the end of the command and
the screen loads. But!!! there is limited use but crashes randomly and
without any warning, here is the crash log (hs_err_pid27490.log):

Any help would be greatly appreciated. Idealy I would like a solution to use
the FreeBSD vm of java or to increase the reliability on linux ABI. I am
willing to compile such a verison for FreeBSD and I do have Qt4.1.2
installed.
My system:
FreeBSD 6.0
jdk-1.5.0p3_2
linux-sun-jdk-1.5.0.07,2
Many thanks
David

Hi David,
I must say I'm impressed with your effort to make this work on FreeBSD ;-)
We should have stated more clarly in which platforms are tested and
supported. We intended the binary package to be working for standard
linux distros, and did not consider FreeBSD in this group, so this was
never tested.
The final version of Jambi will of course be available on all relevant
platforms. Hopefully then as a prebuilt binary for the Java crowd.

Any virtual machine that supports Java 1.5 and JNI could theoretically
be used when we build from sources.

I'm afraid I'm going to have to ask you to wait until a later preview or
the final version for FreeBSD to work ;-)
Jambi also requires Qt 4.1.3, because of the way we layered QThread on
top of Java native threads. We require some adoption inside the Qt core
to make this work.
