Hello Akemi thanks for the tip, but it didn't work: [root@raspi4 ~]# rpmbuild --rebuild kmod-mbgclock-4.2.10-5.el8_5.elrepo.src.rpm Installing kmod-mbgclock-4.2.10-5.el8_5.elrepo.src.rpm warning: kmod-mbgclock-4.2.10-5.el8_5.elrepo.src.rpm: Header V4 DSA/SHA1 Signature, key ID baadae52: NOKEY warning: user akemi does not exist - using root warning: group build does not exist - using root warning: user akemi does not exist - using root warning: group build does not exist - using root warning: user akemi does not exist - using root warning: group build does not exist - using root error: Architecture is not included: aarch64 [root@raspi4 ~]# Am 23.12.21 um 19:46 schrieb Akemi Yagi:

Hi Andreas,

ELRepo has 'kmod-mbgclock' built for x86_64:

https://elrepo.org/linux/elrepo/el8/SRPMS/kmod-mbgclock-4.2.10-5.el8_5.elrep... https://elrepo.org/linux/elrepo/el8/SRPMS/kmod-mbgclock-4.2.10-5.el8_5.elrep...

I wonder if you can just build the aarch64 version by modifying the spec file. Maybe worth trying. You'd be building a kmod package that is supposedly kABI-tracking.

The README file says:

Linux kernels 2.6.x, 3.x, 4.x and 5.x up to at least 5.6 - on standard PCs (i386 architecture) - on Intel/AMD 64 Bit systems (x86_64 architecture) - on SPARC64 architecture - partially on IA64 (Itanium) architecture - partially on ARM architecture

I don't know how "partial" it is on ARM.

I'd attempt to install the `kernel-devel` package and trying to compile it again.

It also looks like the latest version (4.2.12) may rectify this as per their website which references this error on newer kernels: https://kb.meinbergglobal.com/kb/driver_software/driver_software_for_linux/l...

I'd suggest snagging the latest version of the driver & install the aforementioned `kernel-devel` package and I believe it should compile cleanly.

Hello Cody, thanks for the info about newer driver software. Even with the latest version mbgtools-lx-4.2.18.tar.gz I always get the same error. raspberrypi2-kernel4-devel-5.10.78-v8.1.el8.aarch64 is installed. I got it work: just reinstall raspberrypi2-kernel4-devel-5.10.78-v8.1.el8.aarch64, then make, make install without make clean. Now I can switch from my old timeserver based on CentOS 7 (32bit) to update AlmaLinux on Raspberry PI 4 Mit freundlichen Grüßen Andreas Reschke Dr. Bierologis causa
