[Qemu-devel] [Bug 1042388] Re: qemu: Unsupported syscall: 257 (timer_create)

[Predrag Radovic]

Until proper patch is available I'm using attached temp workaround.

After some testing GHC and produced executables appear to work correctly
in foreign arch chroot.

I'm sure there will be issues but I only need compilation to work in
foreign arch chroot because I will deploy produced executables to
Raspberry Pi anyway.

cabal-installing works too but I had to comment out anything related to
Template Haskell from (to be installed) packages.

versions:

qemu 1.4.1 (static build)
host: Linux proton 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 
x86_64 GNU/Linux
foreign: Linux proton 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 
armv6l GNU/Linux
chroot created from 2013-02-09-wheezy-raspbian.img
ghc 7.4.1-4+rpi1 armhf


** Patch added: "temp workaround to enable compilation and execution of GHC  
and produced executables in foreign arch chroot"
