Hi,
I'm trying to build DirectFB 1.5.3 with gcc-4.6 on debian-armel sid,
targeting armv7. I'm attempting to build it on the device, as opposed
to cross-compiling, and I'm currently running into assembler errors.
I'm attempting to build from source, as opposed to using DirectFB
1.2.6 currently in apt, because of the support for PowerVR in the
newer DirectFB releases.
Here's the output of /proc/cpuinfo and autogen.sh:
root@cm-debian:/opt/som/DirectFB# cat /proc/cpuinfo
