Evo-wine app can't copy files

[dividedbymyself]

I'm trying to run the Wine-evo application, but obviously I'm doing something wrong as I get errors. I've installed Wine straight from the repository on Ubuntu 10.04 and extracted the evo.linux.001.tar.gz file to the project directory. I don't have a /usr/bin/wine directory, but I do have a 'wine' executable file in the /usr/bin dir.

When the evo app starts I get tis error:

Code: Alles auswählen

and the stderr out says the following:

Code: Alles auswählen

<![CDATA[

]]>

The in the error mentioned preferences file is in the correct directory. Is there maybe something wrong with the permissions?

I hope someone can help to get Evo running.

I think there is a problem with the permissions. can you post the output of

Code: Alles auswählen

ls -l /path/to/boinc/projects/yoyo/

[dividedbymyself]

Here it is:

Code: Alles auswählen

I think it has to do with the root permission of the files I copied into the dir. If so, how can I change them to give the appropriate permissions to the Boinc account? And will Wine be able to handle that?

Bart

Edit:
I've tried to change the permissions of the files through the GUI (right-click/properties/permissions), but this doesn't change the permissions in the ls -l listing

[Txt.file]

you will ne to do this on a shell. because you have to be root to change root's files. And with Linux you are a normal user as long until you tell the system to become root.

at least you have to change the ownership to boinc. with ubuntu do a

Code: Alles auswählen

sudo chown boinc:boinc /path/to/boinc/projects/yoyo/*

I'm not sure if the permissions then are accurate but it should work.

[dividedbymyself]

I changed the permissions the way you advised. This is the new ls -l directory listing:

In the second column the permission still seems to be root, but I have no clue what's the difference between the second and third columns. Maybe write and read?

I've set Yoyo to allow new tasks again and I'll see what happens let you know how it works out.

Thanks for your help.
Bart

[Txt.file]

the output of ls is:
permissions | owner | owner-group | filesize | date of creation (i think) | name

so I don't think that it will work if only the group is boinc but the owner is still root. but otherwise I wonder why the owner wasn't changed when you used boinc:boinc
someone else any idea?

[dividedbymyself]

I just suspended other projects to get evo running and after 10 minutes it's still running which didn't happen with the previous permissions, so my first impression is that your solution did the trick anyhow.

I'll let it finish before I resume the other projects to see if it finishes and uploads well. With the current DCF it's estimated almost 24 hours, but I don't know if it will go beyond 100% like evo always does in Windows.

Fingers crossed.

Thanks and I'll report back.
Bart

[dividedbymyself]

I'm back somewhat sooner than I had hoped for. Now things have become totally hilarious. I was in the process of suspending of all the rest of the projects to make sure Evo would finish without interruption and then at once the boinc-client stopped and there's no way to get it back running again.
I tried a reinstall of Boinc and several reboots later it still won't work.
There's an error at the end of the install process though:

Does anyone have a quick fix for this? Otherwise I maybe better do a fresh install of Linux tonight (European time). It's only a crunch-box with not much else on it, so this may be a quicker solution then to figure out what's going wrong and get Boinc up and running again...

And he is back again. I did a fresh install of Xubuntu, Wine & Boinc. I also know now what I did wrnog with the file ownership: I forgot the asteriks (*) at the end of the path in the chown command. It must be hard to be dealing with those commandline n00bs Sorry, my mistake
An Evo/Wine Wu is now running and haven't attached to another project yet. Now let's see what it does. It's supposed to take 15 hours according to BM.

Thanks,
Bart

[Txt.file]

I changed the permissions the way you advised. This is the new ls -l directory listing:

because you said that i thought that you did it with * and everything. when i wrote the command i thought about adding "dont forget the * at the end. it's not there just for fun." anyway now it looks working for you.

please report when the WU is validated.

[dividedbymyself]

The stupidest thing is I noticed the asterisk in your instruction, I even know what it means, but I just forgot to type it. Now everything in the owner and owner-group columns is set to boinc, so hopefully it will finish ok now.

I'll report back for sure.

Bart

[dividedbymyself]

Again, like before, the client is stopped and can't get it started anymore . I forgot I can uninstall Boinc with the purge command, but fortunately this emerged in my head again so I tried it and after re-installing I can normally run Boinc again.

I think I better not try Evo again, at least not in Wine, unless someone thinks to know what could have gone wrong. Let's hope someone does, I'd hate to drop this project.

Thanks for the help so far.
