======================================================================== Java installer for Tiny Core Linux by Sercan Arslan <arslanserc@gmail.com> ======================================================================== Before proceeding You must download jdk-8u65-linux-i586.tar.gz from http://www.oracle.com/technetwork/java/javase/downloads/index.html to /home/tc
When i went to the Oracle site i did not find "jdk-8u65-linux-i586.tar.gz" but only "*.sh" ; a "*.tar.gz" file existed only for the jre kind (?)

Jou just need to click on the download banner..

Directly below "Java SE Downloads" click on the download banner with the description "Java Platform (JDK) 8u65 / 8u66".
This leads you to "Java SE Development Kit 8 Downloads". This is what you want.

Admittedly, not the most intuitive info message.

Yes, seems so. Might that be an effect of zram? I remember, to have the GetLatestFirefox script to work, i had to turn off the zram feature (nozswap in the bootcodes). Should i try that?

More generally, is it reasonable to have the zram feature turned on or better turned off? My netbook has 1 gig of ram ... (And i have this problem even in other circumstances, sometimes, so if you think this machine might work smoother without, i'd follow your advice :D ).

Thanks in advance!

Post by: emninger on November 26, 2015, 10:51:03 AM: I changed the following:
- added nozswap to the bootline
- added swapfile=sda1 (after i created a file /mnt/sda1/tc.swp - had to do it by hand, the control panel didn't do it)

Now, the java-installer went a bit further. It still failed, but i didn't get anymore a compromised ram. So i could look into /tmp/java-installer.log:

Code: [Select]
sed: /usr/local/share/applications/sun-javaws.desktop: No such file or directory cp: error writing '/usr/local/src/java/jdk8/usr/local/java/./jre/lib/i386/libprism_common.so': Auf dem Gerät ist kein Speicherplatz mehr verfügbar
(There are still many other rows like the second, referring to other files but with the same error msg: No space available on the device).

Now, that's what i do not understand:

free -m says:
Code: [Select]
tc@box:~$ free -m total used free shared buffers cached Mem: 999 892 106 0 7 457 -/+ buffers/cache: 427 572 Swap: 1023 650 373 tc@box:~$
And on sda1 there are used 3,6 GB while still 12 GB are available (so says xfe). With conky i could follow how the swapfile got populated during the installation attempt (but it was never more than 60%).
