This is the error preventing the build: ERROR (dkms apport): kernel package linux-headers-6.15.0-061500rc5daily20250509-generic is not supported
The compiler version warning is just that (a warning), and I've never seen it cause an issue if the numbers match. Re-titling bug and assigning to evdi-dkms, at least for now. ** Package changed: linux (Ubuntu) => evdi (Ubuntu) ** Summary changed: - False detection of mismatched compilers prevents evdi-dkms module build success during kernel installation + Kernel 6.15 support -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2110334 Title: Kernel 6.15 support Status in evdi package in Ubuntu: New Bug description: Hello, I am running Ubuntu 25.04 and trying to install the latest daily mainline kernel (6.15.0-061500rc5daily20250509-generic_6.15.0-061500rc5daily20250509.202505090206_amd64).

Are they in fact the same compiler version? If so, how can I get the module to build successfully? I have attached the make.log file, but could not post the recommended output of cat /proc/version_signature > version.log or sudo lspci -vnvn > lspci-vnvn.log because I get the errors (respectively). cat: /proc/version_signature: No such file or directory pcilib: Error reading /sys/bus/pci/devices/0000:00:08.3/label: Operation not permitted Thanks!
