Difficulty compiling Linux kernel for ni/nilrt/nilrt/19.1 and ni/linux/nilrt/19.1/4.14 about nilrt HOT 2 CLOSED

Thank you for the information about the Dockerfile - building that and installing a few extra packages (libncurses-devel for menuconfig, libelf-dev, squashfs-tools) allowed me to successfully build the kernel and modules.

Loading them by following the instructions in KERNEL_SOURCE also worked smoothly and after rebooting into safe mode to disable the startup application (which I think caused some lockup due to the NI drivers not having been reversioned when I first rebooted) I managed to get everything booting, running as before and with a new module compiled.

Thanks for the help!

Yes, nilrt/19.1/4.14 branch in ni/linux is correct.

The kernel sources already contain a defconfig (nati_x86_64_defconfig) that can be used instead of needing to copy config file from target.

I haven't tested gcc 8.3.1 specifically but was able to compile the kernel by running make nati_x86_64_defconfig and make with gcc 7.4.0 and gcc 6.3.0, Some of our team members also had success compiling with gcc version newer than 8.3.1.

If that doesn't work on your machine, there is a Dockerfile in https://github.com/ni/nilrt/tree/nilrt/master/sumo/scripts/docker (that installs gcc 6.3.0 at this time) that I verified works.
