The new version of LODA works perfectly under Windows 11. However, it doesn't work at all under Linux (Mint and CachyOS).

Here's a Stderr.txt file from one of my computers:

<core_client_version>8.2.8</core_client_version>
<![CDATA[
<message>

</stderr_txt>

I hope LODA can fix this quickly.

For Ubuntu or Linux MInt try this:
apt install libzip4t64 -y; apt install libzip4 -y;

When both commands fail, you might have a higher version of Ubuntu / Mint, which does not have this library in repositories anymore, so try the zip library version 5 and symlink it to v4:
apt install libzip5; ln -vs /usr/lib/aarch64-linux-gnu/libzip.so.5 /usr/lib/aarch64-linux-gnu/libzip.so.4

Still this error on my Win11 machine, even after the reset of the project.

Solved with the upgrade of the Git to the latest version for Windows...

Now, after i upgraded Git to the newest version and resettet Boinc and resettet the Project, it is working.
But what i saw at the Task manger from Windows is quite unnormally. The 8 WUs of mine got 0% of CPU-Times for ca. 9-10 Minutes After this they run with the normal rate. The RAM increased in this time from 500-700 Mb to at least 1.5 Gb.
But on my Linux machines its not working. I tried the hints i found in the forum but none of them worked.

Conan: which OS and version are you running on? Can you plese try to test executing the loda binary in the project folder? I suspect a missing library.

Sorry for taking so long to respond.

The problem is not a missing library but too old a GLIBC version as I get this

./loda-260310-linux-x86: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by ./loda-260310-linux-x86)
./loda-260310-linux-x86: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by ./loda-260310-linux-x86)
./loda-260310-linux-x86: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by ./loda-260310-linux-x86)

Would need to upgrade the Linux version that I have.
Not really wanting to do this as it works for the many other projects that I run and I don't want it to fail like it did once before when I tried to upgrade so I will leave that computer out for the time being.

I will let the project run on my other computers

Getting a heap of these again, last 39 all failed

I also got this issue on Mac and Linux today

i crunch for Ukraine

Version 260314 was build with GLIBC 2.31. Can you please try to run this loda binary manually and share error messages?

May I kindly ask, if there is a solution? For me the error seems unchanged for a longer time meanwhile on my windows 10

Not sure if this is the same bug but I saw many errors like this on my Windows 10 machine. I wonder if that is some concurrency issue triggered by multiple WUs running at the same time...
