Hi,
I tried to compile OpenWrt barrier breaker for my APU1C4 but it fails (obviously, my first doing something like this).
I started from the x86 generic config file in the download section and enabled 64 bit support and SMP (symmetrc multi-processing)
The strange part is that the error says this (I checked, "loadable module support" should be enabled):

Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled.

I hope someone can help me with this. I'm really a newbie here and have no idea where to start looking (except "make menuconfig" and "make kernel_menuconfig")

I would upload the my config file, but I can't find the upload button in this forum.

I have errors like this , I do not know how to overcome it.

OpenWrt creates Kernel config files from defaults at
- target/linux/generic/config-(kernel_version)
- target/linux/x86/config-(kernel_version)
or at other locations (package/kernel/linux/modules ...)

Those errors are missing symbols in one of these two files (or at another location).
there should be a line "CONFIG_NFS_V3=y" in a generic/config-... file
(afaik corresponding to your log "NFS client support for NFS version 3 (NFS_V3) [M/n/?] m")
but a line with

# CONFIG_NFS_V4_1_IMPLEMENTATION_ID_DOMAIN is not set

is missing
