RPM – Fixing ‘Ancient’ Source Rebuilds..

Posted on February 12, 2015 by RGFebruary 12, 2015

I had occasion to install an ancient GTK+ app, recently, and had to use # rpmbuild –rebuild xxxxx.src.rpm to (re)create some old RPMs from source.. I got the following error: /home/rgadsdon/rpmbuild/BUILD/php_gtk-1.0.2/main/php_gtk_object.c: In function ‘php_gtk_args_from_hash’: /home/rgadsdon/rpmbuild/BUILD/php_gtk-1.0.2/main/php_gtk_object.c:410:4: error: format not a string literal and no format arguments [-Werror=format-security] php_error(E_WARNING, buf); ^ So, I needed to remove the –Werror=format-security parameter … Continue reading →

3.19 Final – NVIDIA and (Patched) VMware OK..

Posted on February 10, 2015 by RGFebruary 10, 2015

Updated the test system to Kernel 3.19 ‘final’, and – as expected – the latest NVIDIA (346.35) and VMware 11.0 (with the vmnet patch..) compile and boot/load OK.. Quite a lot of changes from -rc7, and some reverted.. More details here : http://lkml.iu.edu/hypermail/linux/kernel/1502.1/00199.html $ uname -a Linux rg6830l 3.19.0 #1 SMP Mon Feb 9 14:53:53 PST 2015 … Continue reading →

ARM – Odroid U3 Kernel Compilation..

Posted on February 8, 2015 by RGMarch 3, 2015

This is a workflow for compilation of a kernel + device tree for the Odroid U3. There are other ways of doing this, but this one works, for me.. Compilation works fine on the device itself, so no need for cross-compilations.. This is for a device with root filesystem and boot partition on one SDcard.. Source from: … Continue reading →

ARM – Odroid U3 to 3.19-rc7 – Fan ‘Fixed’?

Posted on February 5, 2015 by RGFebruary 5, 2015

Updated the Odroid U3 to Kernel 3.19-rc7, from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Had to ‘refresh’ the config, by # make exynos4412_odroid_defconfig, and then (re)enable selinux etc… One feature is that the CPU fan no longer runs constantly, but I need to do more tests, to see if it is now capable of running at all.. The temperature is OK, at … Continue reading →

Kernel 3.19-rc7 – ‘Final’ Soon?

Posted on February 4, 2015 by RGFebruary 4, 2015

Installed Kernel 3.19-rc7 on the test system, and the same comments apply as for -rc6. The latest NVIDIA driver (346.35) and VMware 11.0 – with the vmnet patches – install and load/run OK..

ARM – New Raspberry Pi 2 – ARMv7 at Last..

Posted on February 2, 2015 by RGFebruary 2, 2015

For those who have a new Raspberry Pi 2 on order – as I have – the kernel source is now available, at https://github.com/raspberrypi/linux/tree/rpi-3.18.y-rebase. To get the correct config, start with # make bcm2709_defconfig For me, one of the additional benefits is that it is ARMv7, which should support the standard up-to-date Fedora 21 distro, instead of … Continue reading →

Posted on January 27, 2015 by RGJanuary 27, 2015

Updated to Kernel 3.19-rc6 on the test system, and – at last – the problem with NVIDIA driver GPL inconsistency has been fixed, and now driver 346.35 compiles and loads OK.. Details of changes since -rc5 are here: http://lkml.iu.edu/hypermail/linux/kernel/1501.3/00776.html And the important change is that /arch/x86/mm/init.c now has EXPORT_SYMBOL(__cachemode2pte_tbl) instead of EXPORT_SYMBOL_GPL(__cachemode2pte_tbl)..etc..

VMware – Backward-Compatible 3.19 Fix..

Posted on January 23, 2015 by RGJanuary 23, 2015

After the solution to the Kernel 3.19/vmnet problem mentioned in previous posts, I have produced a fix that includes tests for kernel versions, and works with Kernel 3.19 and with earlier kernel versions.. This is probably not the most elegant code, but it works – I have tested it with VMware 11.0 and Kernels 3.19-rc5 and 3.18.3 … Continue reading →
