REW and linux mint

Hi,


recent versions fails to run, only Rew 5.0 runs fine but a bit outdated...
OS is linux mint 18, I try with openjdk and Oracle's jdk with same results.
So I'm asking for some help...

Rew 5.18 fails with :

$ java -jar RoomEQ_Wizard_obf.jar
Exception in thread "main" java.lang.NoClassDefFoundError: com/install4j/api/launcher/StartupNotification$Listener

Thanks,

Re: REW and linux mint

I having similar issue

REW was able to run in ubuntu 16.04 with Java 6, but had problem with the sound output preference. Then I realized REW runs in Java 7 or 8, so I uninstalled java 6 and installed Java 8. Now REW 5.18 and 5.17 refuse to run.

Looking forward to any help rendered.

Thanks.

Re: REW and linux mint

Try the latest 5.19 beta version, the installer was updated just before that was generated so if the exceptions are due to an installer bug it may have been fixed in the update.

Re: REW and linux mint

I found something similar from a couple of years ago, in that case it would start as Admin but not as a normal user. Solution was to edit the roomeqwizard.vmoptions and adjust the maximum memory usage to 768 MB (-Xmx768m). That was from here.

Re: REW and linux mint

Changing the maximum memory doesn't solve the problem, error message is still the same. Tried with 512M, 768 and 1024 as a normal user and as the super user.

Re: REW and linux mint

I don't know what to suggest then. All it really seems to be saying is the application couldn't start, see that same pattern from a Google search for various applications packaged with install4j. If the latest Oracle Java 8 JRE doesn't help then I'm out of ideas, sorry.

Re: REW and linux mint

Ok, thanks for the replies.
I have it running in a fresh install of linux mint 18 in a virtual machine, sound trough the networking capabilities of pulseaudio. Seems to be usable...

Re: REW and linux mint

Not sure if this helps, but I have REW 5.19 Beta 4 running in Linux Mint 18 (Sarah) with Oracle Java 8 JRE. Everything works great. I don't know if I can provide any kind of setup/data/log info that might help you figure out. I'm using an old HP Elitebook with a Behringer UCA222 external USB soundcard. It's a native installation of Linux, it used to have Win10, which completely broke all normal functionality of the laptop, so I just installed Mint over it and it has worked awesome ever since.
