KDE Rounded Corners is not supported by Kwin anymore [Error]

[OzzyHelix]

I have this error and have no idea how to make it go away it appears when I start my dessktop every time I start KDE and goes away after failing to build Rounded Corners any help with this is appreciated

The message is clear: "Compile Manually". It allows you to read logs. It happened to me once that my gcc-12 package was removed and I had to reinstall it to make the compile work again.

[OzzyHelix]

I tried to downgrade to 5.15 to fix an issue with an MSI usb wifi card and maybe gcc got messed up in the process of doing that I am not on that anymore but I reinstalled gcc13 hopefully that helps sorry for being dumb

[OzzyHelix]

it fails to install it will build but it fails to install I also don't know where the logs are

[OzzyHelix]

running this results in false it seems to fail to load not sure why

❯ sh ../tools/load.sh
false

[OzzyHelix]

I will try install gcc12 but I'm confused because I have gcc13 and gcc14 so why would I need gcc12?

[matinlotfali]

I am not saying you need a specific version of GCC. I am saying in my case, that was the reason the rebuilding was failing. It was looking for a specific compiler but was failing at the time. It might be different on your distro. What do commands gcc --version and g++ --version show you?

[OzzyHelix]

the thing is compiling it manually doesn't error out I think what might be happening is KDE might be trying to run sh ../tools/load.sh and it returns false because rounded corners is already enabled causing it to be stuck in a loop of trying to upgrade what it thinks is an incompatible plugin

[OzzyHelix]

that is what I think is going on anyways

[matinlotfali]

Run sh ../tools/test-install.sh on terminal inside build directory. What does it show in the output?

looking at the log there is a permission problem with /home/ozzy/Documents/development/KDE-Rounded-Corners/build/install_manifest.txt

[OzzyHelix]

after running that I get this now

KDE-Rounded-Corners is supported by KWin and doesn't need re-installation.

so I guess we will see on restart if its fixed

[OzzyHelix]

yeah I seem to have figured it out with that command thanks
