Compilation error: java.io.IOException: Cannot run program "cp": java.io.IOException: error=12, Cannot allocate memory

[Ulf]

Hi everyone.

I’m almost giving up, this will be my last try: I try to compile
Etherpad on my OpenVZ server. It’s running a Debian 5.0 as the host
system, in the VE I’ve got Ubuntu 10.04. I installed Etherpad in this
VE with the instructions from the official Ubuntu Wiki:
https://wiki.ubuntu.com/Etherpad.

Everything runs fine until it comes to compilation. After calling bin/
build.sh as described in the wiki the first steps are running fine.
But then I’m running into a memory error:

java.io.IOException: Cannot run program "cp": java.io.IOException:
error=12, Cannot allocate memory
Well, I understand the error message but don’t see the cause. The
command free tells me that there’s plenty memory left in this VE:

total used free shared buffers
cached
Mem: 2415236 1140872 1274364 0
0 0
-/+ buffers/cache: 1140872 1274364
Swap: 0 0 0

Beautiful. But even repeating the compilation process doesn’t bring me
any further.

Any help would be appreciated.

you need swap space for etherpad

google search for etherpad minimum requirements.

OK, I managed to add swap space to my VE:

total used free shared buffers
cached

Mem: 4025396 2602484 1422912 0 62164
1048164
-/+ buffers/cache: 1492156 2533240
Swap: 4200888 0 4200888

Another call of the build script results in this error:

Cannot start compilation daemon.
tried command: scala scala.tools.nsc.CompileServer
Cannot start compilation daemon.

Exception in thread "main" java.lang.Exception: fsc failure

Have you tried installing the apt package?

this was recently fixed. new source is

deb http://apt.etherpad.org all .

[Ulf]

I actually did. My installation is more or less 1 day old. And I used
the mentioned APT package.
