 Posted: Fri Sep 30, 2016 3:38 pm Post subject: gcc-5.4 icedtea-7 or 8 lightzone (semi-solved) |
 |
|
Lightzone (installed as per the instructions for gentoo given in http://lightzoneproject.org/lorum/install-lightzone-gentoo)
worked just fine with gcc-4.9.4 and icedtea-7 or icedtea-bin-7.
However since I upgrade to gcc-5.4 it fails with the error
| Code: | ightzone
Starting LightZone version 4.1.7 ...
with options :
openjdk version "1.8.0_101"
OpenJDK Runtime Environment (IcedTea 3.1.0) (Gentoo icedtea-3.1.0)
OpenJDK 64-Bit Server VM (build 25.101-b13, mixed mode)
jh.jar was not found.
This is LightZone 4.1.7 (79fa0e3)
Running Java version 1.8.0_101 (amd64)

... 5 more |
In particular note the error
despite the fact that copies of it exist at | Quote: | | /usr/local/LightZone/jh.jar |
and | Quote: | | /usr/share/javahelp/lib/jh.jar |
Any suggestions on how I can fix this other than reverting to gcc-4.9.4? Is there a known problem with icedtea under gcc-5.4?
PS This is the only problem that I have encountered with my upgrade to gcc-5.4. Icedtea and lightzone do build with gcc-5.4

This appears to have nothing to do with gcc-5.4.
I did revert to gcc-4.9.3 by using a backup. At this point lightzone worked again.
However I then tested by recompiling lightzone using gcc-4.9.3. The problem mentioned above with lightzone not running reappeared,
so I reinstalled the previous backup to get it running again. I have now added lightzone to /etc/portage/packages.mask
to keep it from being compiled again.
I don't know what the cause of the problem is, but I advise that if you have a working lightzone don't recompile it. |
