You can run the boinc client with --exit_before_start. Than boinc exits before the wu starts. In this case boinc copied everything into the slot directory. There should be the wrapper, the dnet binary, the job.xml and the input file in.og2. In the slot directory you should be able to start the wrapper on the command line.

OK, I got the sandbox set up. Which exact command should I run from the appropriate slot directory?

Here's what I got in the directory:

Code: Alles auswählen

$ ls boinc-client/slots/0/ -l
total 1.3M
-rwxr-xr-x 1  somebody  1.3M 2013-03-07 16:44 dnetc*
-rw-r--r-- 1  somebody  4.8K 2013-03-07 16:44 init_data.xml
-rw-r--r-- 1  somebody  1.3K 2013-03-07 16:44 in.og2
-rw-r--r-- 1  somebody   100 2013-03-07 16:44 job.xml
-rw-r--r-- 1  somebody    87 2013-03-07 16:44 stdout
-rw-r--r-- 1  somebody   104 2013-03-07 16:44 wrapper_519.02_arm-unknown-linux-gnueabi

TIA

The wrapper seems to be just a symlink into the project directory. So copy the wrapper into the slot directory and start the wrapper without any parameter. This is what boinc would do.

This is weird:

Code: Alles auswählen

$ cat wrapper_519.02_arm-unknown-linux-gnueabi 
<soft_link>../../projects/www.rechenkraft.net_yoyo/wrapper_519.02_arm-unknown-linux-gnueabi</soft_link>

Copying the program over and trying to run it:

Code: Alles auswählen

$ ./wrapper_519.02_arm-unknown-linux-gnueabi
-bash: ./wrapper_519.02_arm-unknown-linux-gnueabi: Permission denied
$ chmod +x ./wrapper_519.02_arm-unknown-linux-gnueabi
$ ./wrapper_519.02_arm-unknown-linux-gnueabi
-bash: ./wrapper_519.02_arm-unknown-linux-gnueabi: No such file or directory
$ ldd ./wrapper_519.02_arm-unknown-linux-gnueabi
        libm.so.6 => /lib/libm.so.6 (0x40006000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x400ae000)
        libc.so.6 => /lib/libc.so.6 (0x400cf000)
        /lib/ld-linux-armhf.so.3 => /lib/ld-linux.so.3 (0x2a000000)
        ld-linux-armhf.so.3 => not found

It seems that the wrapper was built for ARM with hardware FP. Could you please rebuild it for software FP, since I doubt that it cares?

TIA

I send you a DropBox invitation. There are the Makefile and wrapper source. Can you compile it for me?

I got errors galore. Which version of BOINC should I use?

[yoyo]

This one. Run a make clean before.

Got it. I put the new wrapper here. I believe that it's universal enough even for the Raspberry.

I'm running Dnet again with this new wrapper:

Code: Alles auswählen

$ ps fT
  PID TTY      STAT   TIME COMMAND
 4319 pts/1    Rs     0:01 -bash
13557 pts/1    Sl     0:00  \_ ./wrapper_arm-unknown-linux-gnueabi
13559 pts/1    RN    24:55  |   \_ dnetc -runoffline -multiok=1 ...

Stay tuned.

Dnet finished crunching a WU on the ARMv5 after 2h50min.

I don't see the wrapper in Dropbox?

Sorry, I couldn't write in the shared Dropbox. I put it here.

[yoyo]

Thanks. I create a 519.04 version with it. Please test.
