Nios II SBT Crashing on Linux

I'm having a problem when trying to open the Nios II SBT from Quartus on Linux. I've tried to use Quartus 18.1 and 20.1. When opening from the directory "quartus/nios2eds/bin/eclipse-nios2" using t...

    The following workaround seems to work, it essentially replace Quartus included java engine with Java 8

    cd ..../intelFPGA/20.1/quartus/linux64
    mv jre64 jre64_old
    ln -s /lib/jvm/java-1.8.0-openjdk-amd64/jre jre64

    the path to Java 8 jre might be machine specific, mine is at least placed there

Hi Felipe,


I'm glad to read version 19.1 is running without any issue.

Once again thank you for contacting us, I'll keep debugging the initial issue so we can fix it in future versions.



Regards,

      ln -s /lib/jvm/java-1.8.0-openjdk-amd64/jre jre64

      after those commands, SBT doesn't start anymore.

        This solves the "free():Invalid pointer" error for the Nios II SBT, but the plataform designer started to have problems with some java classes.

        Also, Stephane solution seems to solve the GTK warnings at the eclipse launch.

        @Eliath_G_Intel, is there any update about it?

        Thanks,

      Hi everyone,

      It seems to be an error in GTK

      OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

      (Eclipse:225473): Gtk-WARNING **: 22:27:00.086: Negative content width -6 (allocation 1, extents 4x3) while allocating gadget (node toolbar, owne
      r GtkToolbar)

      (Eclipse:225473): Gtk-WARNING **: 22:27:00.086: Negative content height -6 (allocation 1, extents 4x3) while allocating gadget (node toolbar, own
      er GtkToolbar)
      free(): invalid pointer

        Hi everyone and @Eliath_G_Intel ,

        I found a solution :

        run in konsole:

        export SWT_GTK3=0
        export SWT_WEBKIT2=1
        ./eclipse-nios2

        and GUI will be launched correctly
