Subject: [musl] User mode linux error when compiled with musl
Date: Mon, 30 Mar 2020 19:21:48 +0200	[thread overview]
Message-ID: <d9d3a821b81fd3b92a91b775772b604e@hanne.name> (raw)

Hi,

I'm compiling user mode linux (kernel 5.5) against musl (toolchain from 
musl.cc, tried gcc 6 and gcc 9) and getting the following error when 
booting:
--
Run /init as init process
userspace - ptrace set fp regs failed, errno = 14
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
--

build command: make ARCH=um LD_FLAGS_CMDLINE="-static" 
CROSS_COMPILE=x86_64-linux-musl-

run command: ./linux initrd=test.cpio.gz

test.cpio.gz contains a statically linked "Hello world" init, which 
works when UML is built against the host cc with glibc (Ubuntu 16.04, 
gcc 5, also with "-static").

Any ideas?

Regards,
   Johann
