The thing is, that some people say, that it is necessary to use a patched version of KVM by using it with the realtime preemption patches.

I understood, if I want to compile the kvm package, including the kernel modules, I don't have to use the "--with-patched-kernel". Am I wrong? I'm a bit puzzled at the moment, as it seems, that the "--with-patched-kernel" switch is incompatible with "--kerneldir" ?? kerneldir is a path to my patched 2.6.21.6-rt21 preemptible-kernel for our target, by the way. > > To solve your SDL issue you probably want to cross compile a version SDL > in a directory .. then add to the --qemu-cflags option & > --qemu-ldflags.

A minor problem though and easy to fix... I could send a patch afterwards, when I found a common solution... > > ./configure --arch=i386 > --cross-prefix=/opt/crosstool/i686-pentium-linux-gnu/\ > gcc-3.4.3-glibc-2.3.3/bin/i686-pentium-linux-gnu- \ > --kerneldir=/home/gerdko/thinkiod_work/linux --disable-vnc-tls \ > --prefix=/home/gerdko/thinkiod_work/install \ > --with-patched-kernel \ > --qemu-cflags="--static -I <SDL_DIR>/include -I <zlib_dir>/lib" \ > --qemu-ldflags="-L <SDL_DIR>/lib -L <zlib_dir>/include" > > Another thing that you need to sneak in is that your going to need is > adding "--static" flag into the qemu compilation (which I do in > --qemu-cflags in the example). > > Cross compiling qemu is a little bit of a pain.due to the external > dependencies.
