Details

Compiling custom dvb kernel modules with elfutils-0.175 leads to following errors (for every object file):

objdump: /usr/src/linux-dvb-drivers/media_build/v4l/.tmp_mantis_pcmcia.o: unable to initialize decompress status for section .debug_info
objdump: /usr/src/linux-dvb-drivers/media_build/v4l/.tmp_mantis_pcmcia.o: unable to initialize decompress status for section .debug_info
objdump: /usr/src/linux-dvb-drivers/media_build/v4l/.tmp_mantis_pcmcia.o: file format not recognized

Downgrading to elfutils-0.174 (and the corresponding libelf) fixes this problem.
This task depends upon

Binutils version binutils-2.31.1-4 with upstream patches been pushed to [testing]. Please verify that it fixes your issue and works with other your use-cases. Thanks for the feedback in advance.

I had this problem while compiling kernel modules the normal way -- just make oldconfig && make -j$(nproc).

The binutils update from testing does fix it, I'll try recompiling some other aur packages next.
Comment by Gerhard Bogner (slashME) - Wednesday, 26 December 2018, 18:03 GMT
I had no problems recompiling a few other packages, and had no issues running them (or the kernel modules) so far.
Comment by Anatol Pomozov (anatolik) - Wednesday, 26 December 2018, 18:07 GMT
Sounds great. I'll keep binutils in testing for a while. If anyone finds any issues with this patched version please let me know.
