[gentoo-soc] cross_container_support - progress report #7

[Jing Huang]

Hi,

   == Progress of last Week ==

In the last week, I continue to debug the lxc script for arm-gentoo
container and investigate how to execute x86 program in arm container.


First, I try to fix the ping issues in qemu-user of arm-gentoo
container. The patch is attached.

* The do_setsockopts function in qemu-user does not support SOL_RAW
socket which is used in ping program.

* The recvmsg in main_loop of ping_common.c could not fetch
sockaddr_in struct. That is because do_sendrecvmsg in qemu-user does
not pass the msg->msg_name to the target.
So the ping will show "64 bytes from 0.0.0.0: icmp_req=1 ttl=64 time=1.16 ms".


Second, I am investigating how to execute local gcc toolchain in
arm-gentoo container.

At begging, I want to use ldd to parse each cross-gcc toolchain
executable in arm container. Then copy the related libraries to
gentoo-arm rootfs and config the ld.so.conf to make cross-gcc running
locally.

Now, I think I could modify the crossdev script and build cross-gcc
with LDFLAGS="-static". So the cross-gcc can be executed locally in
arm-gentoo container.


I have about one week behind the schedule. I hope I could catch up it
as soon as possible.


Jing.
