Re: [Qemu-devel] [PATCH] -chroot and -su options.
Hi, On Mon, Mar 3, 2008 at 8:28 PM, Rob Landley [EMAIL PROTECTED] wrote: Quick and dirty patch to teach qemu application emulation how to chroot (and drop privs), so you don't have to pollute a target filesystem with host code, and/or figure out how to build qemu static in order to run a dynamic binary.

Re: [Qemu-devel] fix for qemu-* looping forever on symlinks (patch attached)
On 7/13/06, Paul Brook [EMAIL PROTECTED] wrote: The whole point of the -L option is so that it picks up target shared libraries, eg. in lib and usr/lib. By my reading your patch makes the -L option do absolutely nothing, which can't be right. The proper fix is to do the lookups when a file is accesses (possibly with caching) not pre-scan the whole tree. Is it possible to use the same cache format as ld.so (/etc/ld.so.cache)? So a command like qemu-arm -L /target program would make qemu look for /target/etc/ld.so.cache as its cache, and a command like: qemu-arm -L /target /target/sbin/ldconfig would update this cache. Unless the cache you are proposing has different purposes than ld.so's cache?

[Qemu-devel] [PATCH] Add support for compiling outside the source tree
Hi,
The attached patch adds (or, strictly speaking, fixes, as the source
tree had already initial support for this) support for compiling QEMU
outside the source tree (or in a subdir). As a side effect, it also
removes the requirement to call configure with an absolute path. The
changes are fairly small and don't affect the normal build.

[Qemu-devel] qemu regression 0.7.2 - 0.8.0 (ARM user emulation)
Hi,
I was having some issues with the latest qemu (ARM user emulation),
which I tracked down to the following reduced test case:
#include stdio.h
int main(void)
{
float a, b;
a = 0.1f;
b = 0.8f;
printf(a b: %d\n, (a b));
return 0;
}
Compile it with an ARM cross-compiler and run it with qemu-arm. It
should print
a b: 1
for qemu 0.7.2 and
a b: 0
for 0.8.0. Obviously, the first one is right.
Tested with the following setup:
qemu 0.7.2/0.8.0
arm-linux-gnu-gcc (GCC) 3.4.5
glibc 2.3.5
