7 years ago How I compile kernel modules/drivers natively from a cross-built kernel:
- have your cross compiler generate the deb files
dpkg -i linux-headers-3.8.13xenomai-xenomai-r81_1cross_armhf.deb- all the build tools will now be x86
cd /lib/modules/$(uname -r)/buildmake headers_check && make headers_install && make scripts- if the above fails,
wget https://raw.githubusercontent.com/igorpecovnik/lib/next/patch/headers-debian-byteshift.patch && patch -p1 < headers-debian-byteshift.patchNOTE: this is probably better done by making sure these files are there to begin with - at this point all the build tools will be ARM
- you can now build an example module like this
CONFIG_SND_VIRMIDI yes CONFIG_XENO_OPT_NATIVE_INTR and CONFIG_XENO_OPT_POSIX_INT https://github.com/BelaPlatform/Bela/issues/171
