If this command is actually executed at install time, then it looks like it is trying to install in the build machine's modules dir, since it does not specify INSTALL_MOD_PATH Is that the command that fails? As stated above, please post the full build log, starting with the configure message. It will easier to help if we can *see* the actual error. Otherwise, we also have an infrastructure to build a kernel module, similar to the other package infras. Look for 'kernel-module' in the manual. Regards, Yann E.

OK, so I've had a quick look at your build log, and it looks like linux-gpib is quite a mess and will be difficult to package properly. So, first, let's look at the configure log: Checking Linux kernel directory... ok checking Linux kernel compile flags... FATAL: /home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/util/linux_flags/fake.o has no symtab? make[3]: *** [__modpost] Error 1 make[2]: *** [modules] Error 2 configure: WARNING: Failed to get compile flags from Linux kernel directory. ok checking for arm-buildroot-linux-uclibcgnueabihf-gcc... /home/vagrant/buildroot-2016.05/output/host/usr/bin/arm-buildroot-linux-uclibcgnueabihf-gcc This sounds like it is incorrectly looking for Linux directory for the build system and/or kernel-land headers. Besides, it did not already checked for the cross-compiler, as we can see that it does so *after*, so it is probably using the host compiler at that point (and this will be confirmed later during the build, see below...). That one will be very difficult to fix, especially since their configure.ac is very badly written: 90 dnl get compile flags for modules from linux kernel source tree 91 AC_MSG_CHECKING([Linux kernel compile flags]) 92 FLAGDIR=$(pwd)/util/linux_flags 93 env LDFLAGS="" CFLAGS="" make --quiet -C ${LINUX_SRCDIR} V=1 SUBDIRS=${FLAGDIR} LINUXDIR=${LINUX_SRCDIR} modules > /dev/null 94 if [[ $? != 0 ]]; then 95 AC_MSG_WARN([Failed to get compile flags from Linux kernel directory.]) 96 fi 97 AC_MSG_RESULT([ok]) Since it is not using standard and not passing the compiler, we can't override it will configure flags or any ac_cv_* variable. :-( That will be tough to fix. Unless this is not really needed in fact, and we can in fact pass the expected values in the environment or some such afterwards. And it seems we could do that, as the intermediate file generated in this command (util/linux_flags/flags) is only used later to actually build the driver. So we don;t need it at configure time, and the check can very well fail, we don;t care (but it is nonetheless completely borked). And then, it means we can also probably use our kernel-module infra as well to build the kernel module instead of letting their weirdly borked buildsystem do it. Then not much of interest, until it starts trying to build the kernel module. And there, everything goes down hill pretty quick (lines slightly reformatted by me): /usr/bin/make -C /home/vagrant/buildroot-2016.05/output/build/linux-26f3b72a9c049be10e6af196252283e1f6ab9d1f/ V=1 modules\ CC="gcc -I/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3 -I/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/drivers/gpib/include -I/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/include" \ CONFIG_GPIB_ISA="no" \ SUBDIRS="/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/drivers/gpib" Bing, it uses the host compiler! That's just so utterly broken... :-/ And then (again, reformatted and elided by me): gcc -I/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3 -I/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/drivers/gpib/include -I/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/include -Wp,-MD,/home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/drivers/gpib/ni_usb/.ni_usb_gpib.o.d [--SNIP--] -DMODULE -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(ni_usb_gpib)" -D"KBUILD_MODNAME=KBUILD_STR(ni_usb_gpib)" -c -o /home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/drivers/gpib/ni_usb/.tmp_ni_usb_gpib.o /home/vagrant/buildroot-2016.05/output/build/linux-gpib-4.0.3/drivers/gpib/ni_usb/ni_usb_gpib.c So, really, it *is* using the host compiler, and there is no way, with their infrastructure, to tell them to use another one. Definitely broken beyond repair... So, all we have to do is: - convince it not to try to build the kernel module, - build it ourselves with our kernel-module infra. I'll try to have a deeper look latter... Dinner now. :-) If you hang around on IRC tonight UTC+2, we can talk about it, too. Regards, Yann E.

Thanks again! So, I've done some work to build the kernel modules, too. It works now, but it was far from being easy. linux-gpib uses such a weird, deviously-twisted buildsystem, that building the kernel modules, especially in cross-compilation, is not trivial: - they forget to pass correct include paths; - they override standard kernel headers because they want to provide legacy handling (but even fail at that). I've done a few patches to fix that (and the rest of the install procedure, btw) so that linux-gpib now should work, except for the language bindings, that are yet another challenge to address... :-/ You'll find my branch updated there: https://github.com/yann-morin-1998/buildroot/commits/yem/linux-gpib Regards, Yann E.
