[Android Q&A, Help & Troubleshooting] greatogreat:
I'm trying to compile the LineageOS kernel source for my device Galaxy S4 (jfltexx).

Kernel: https://github.com/LineageOS/android_device_samsung_jflte

Toolchain: https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/

System: Xubuntu 17.10 (64 bit) with gcc 7.2.0 and GNU Make 4.1

In order to compile the kernel for my target, I'm using the build script from the kernel repository:

python build-all.py jf_eur

The compilation usually stops at one point and the log contains the following:

GEN /home/computer/Desktop/output/all-kernels/jf_eur/Makefile

I have been searching the internet, but only found one topic where a user mentioned that 'tracing' caused them this error:

https://xdaforums.com/showpost.php?p=53850620&postcount=32456

Since I'm using the latest kernel sources and the device is still actively supported with complete LineageOS builds, I thought the kernel should probably compile just fine. I also watched some Youtube videos where people compiled kernels the same way I am trying to.

Am I using a wrong toolchain or other programms?

I'm glad for any help, thanks!
