Hello,
I am working on a kernel update from 4.4 to 4.14 in our ptxdist 2016.04
based BSP.
The kernel builds fine, but the modules.dep file is zero bytes long.
I updated libkmod.make from version 22 to 24, but that did not help.
When I run the depmod from sysroot-host/sbin/ by hand it finds no
symbols:
./depmod -a -n -b ~/bsp/platform-xxx/root 4.14.1-00003-gb5f7a9a47e0b
# Aliases extracted from modules themselves.
# Soft dependencies extracted from modules themselves.
# Aliases for symbols, used by symbol_request().
If I run the same with the old 4.4 path I get a lot of symbols / output
./depmod -a -n -b ~/bsp/platform-xxx/root 4.4.79
Does anyone have an idea what could be wrong, or what I can check?
Thanks a lot for your help!
Best regards,
Matthias

Does it work with 'depmod' from your host system? Maybe you enabled module
compression fo 4.14? That's currently disabled in host-libkmod.

Hello Michael,
thanks a lot for the tip!
It was the modules compression which was turned on ...
Best regards,
Matthias
