I have recently been involved in bug reports etc for a new problem in Fedora 40, where a recent update has effectively broken all QT applications, resulting in KDE not functioning, and even # make xconfig is broken. The Fedora bug report is here: https://bugzilla.redhat.com/show_bug.cgi?id=2272758 The problem is: # kwrite Illegal instruction (core dumped) # kate Illegal … Continue reading →
Kernel 6.9-rc1 has been released, and brief details are here: https://lkml.iu.edu/hypermail/linux/kernel/2403.3/00300.html As discovered in pre-rc testing last week, the latest NVIDIA driver – now 550.67 – is OK, and this now compiles successfully with GCC14.. VMware 17.5.1 (patched) vmmon compiles OK, but vmnet fails: ……………… CC [M] /tmp/modconfig-a8Fcf5/vmnet-only/smac.o CC [M] /tmp/modconfig-a8Fcf5/vmnet-only/vnetEvent.o CC [M] /tmp/modconfig-a8Fcf5/vmnet-only/vnetUserListener.o In file included … Continue reading →

I have been carrying out some preliminary tests to see how feasible it is to compile the Linux Kernel, and NVIDIA drivers, and VMware, using the ‘alternative’ to GCC – CLANG.. The kernel compile is relatively easy, and well documented: # make CC=clang HOSTCC=clang -j8 (for a 4-core system) The compile seems to be slower than GCC, … Continue reading →
There is an updated patch for NVIDIA 440-59 with Kernel 5.3, which includes the Y2038 fixes, at https://gitlab.com/snippets/1937313 This compiles with GCC10 now, and I have briefly tested it on my Fedora32 system, with KDE/Plasma and VMware, and it seems to be working OK.

Thanks to Isaak I. Aleksandrov, there is now an additional patch for NVIDIA driver 440.59 to accommodate the Y2038 changes in Kernel 5.6-rc3. This should be applied after the original 5.6-rc1 patch ( https://gitlab.com/snippets/1937313 ), and can be found here: https://gitlab.com/snippets/1944237 I have tested this, and it compiles OK with GCC9 (current distros) but fails with GCC10 … Continue reading →
I have updated some test systems (x86_64 and aarch64) to pre-beta Fedora 32, which now includes GCC 10: $ gcc –version gcc (GCC) 10.0.1 20200216 (Red Hat 10.0.1-0.8) There have been a couple of problems with kernel compilation, but in each case there was already a patch/workaround available.. https://www.spinics.net/linux/fedora/fedora-arm/msg13193.html and https://lkml.org/lkml/2020/1/29/494 The most serious problem was a … Continue reading →
Just updated to the pre-release Fedora 30 (Rawhide) on the test system, and tried out the new version of GCC: $ gcc –version gcc (GCC) 9.0.1 20190209 (Red Hat 9.0.1-0.4) Kernel 5.0-rc7 compiled successfully, and runs OK.

Running Fedora 28 on the test system, I have encountered the following issues with various applications, and found substitute rpm workarounds.. Usually, these can be installed by downloading them ,and then using # rpm -Uvh……… –force.. Grub-customizer still crashes, but the F27 version works ( grub-customizer-5.0.6-6.fc27.x86_64 ) Wine crashes with some windows apps, and the workaround is … Continue reading →
