Hi,
I would like to install a light linux on Qemu ARM VersatilePB. I use my Intel Core i3 to cross compile linux kernel 3.11. So, i've installed ELDK 5 to cross compile to ARM: http://www.denx.de/wiki/ELDK-5/WebHome I followed installation process and all seems ok. In ARM compilation environment: source /opt/eldk-5.5/armv6/environment-setup-armv6-vfp-linux-gnueabi I've configured linux 3.11 kernel to use "versatile_defconfig" : make versatile_defconfig and I've added EABI option. I can't use make menuconfig because it needs ncurses shared libraries and i don't know how to install them with cross-compilation tools. Any idea how to use ncurses with ARM ELDK ? (i tried to cross compile ncurses but i can't generate shared libraries). So I've edited .config file and modified CONFIG_AEABI to yes: CONFIG_AEABI=y I compiled linux kernel without any problem. For my tiny test, i want to load kernel without root file system, just ram disk (initrd) and just an 'init' programm that displays 'hello' every seconds. I've compiled this code 'hello.c': #include <stdio.h> #include <stdlib.h> main (int ac, char **av) { while (1) { printf ("Hello\n"); sleep (1); } } I tried this : arm-linux-gnueabi-gcc -static -o init hello.c Command failed: ...../arm-linux-gnueabi/4.8.1/ld: cannot find -lc collect2: error: ld returned 1 exit status Like said by Wolfgang Denk, it seems that static option is not well supported by kernel : http://lists.denx.de/pipermail/eldk/2012-July/002162.html Unfortunately my test has became a little bit more complex because I've to manage shared libraries by compiling without static option. Last part, before to test with qemu-system-arm,I created an init ram disk with these files into a tmp directory: /dev/ttyAMA0 /init /lib/ld-linux.so.3 /lib/libc.so.6 I used commands: cd tmp find ./ | cpio --dereference -H newc -o | gzip -9 > ../rootfs_qemu.gz I've launched qemu with : qemu-system-arm -M versatilepb -m 64 -kernel linux-3.11/arch/arm/boot/zImage -initrd rootfs_qemu.gz -nographic -serial stdio -append "console=ttyAMA0,115200 mem=64M" And that fails with : CPU: 0 PID: 1 Comm: init Not tainted 3.11.0 #1 Any idea to help me ? Thank you very much. Bet regards, Gilles.
