It might be just coincidence but if you read the above comments you will notice that people who compiled qemu natively on arm report that they can run various binaries without issue but people who crosscompiled report that they can't run the simplest i386 shell utilities.
How come that the functionality that is missing magically appears for some people? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/739785 Title: qemu-i386 user mode on ARMv5 host fails (bash: fork: Invalid argument) Status in QEMU: New Bug description: Good time of day everybody, I have been trying to make usermode qemu on ARM with plugapps (archlinux) with archlinux i386 chroot to work. 1. I installed arch linux in a virtuabox and created a chroot for it with mkarchroot. Transferred it to my pogo plug into /i386/ 2. I comiled qemu-i386 static and put it into /i386/usr/bin/ ./configure --static --disable-blobs --disable-system --target-list=i386-linux-user make 3. I also compiled linux kernel 2.6.38 with CONFIG_BINFMT_MISC=y and installed it. uname -a Linux Plugbox 2.6.38 #4 PREEMPT Fri Mar 18 22:19:10 CDT 2011 armv5tel Feroceon 88FR131 rev 1 (v5l) Marvell SheevaPlug Reference Board GNU/Linux 4.
