[Buildroot] autoconf Makefile in sub-directory

[Buildroot] autoconf Makefile in sub-directory

[Bassem Fahmy]

Hi All,

I have been given a package that is built using autoconf tools. The
package builds fine under native compilation.  The package however
produces the main Makefile under a linux subdirectory

CFLAGS="$CFLAGS
-I/home/bassem/projects/morse_buildroot/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/include/libnl3"
AC_CONFIG_FILES([linux/Makefile
])
;;

Adding an autoconf package in buildroot, buildroot can pass the
configure step, however Make target is failing:

PATH="/home/bassem/projects/morse_buildroot/output/host/bin:/home/bassem/projects/morse_buildroot/output/host/sbin:/home/bassem/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/bassem/tools/riscv64-unknown-elf-gcc-8.2.0-2019.02.0-x86_64-linux-ubuntu14/bin:/home/bassem/tools/riscv-openocd-0.10.0-2018.12.0-x86_64-linux-ubuntu14/bin:/home/bassem/tools"
 /usr/bin/make -j9 -C
/home/bassem/projects/morse_buildroot/output/build/dpp-custom/linux -C
/home/bassem/projects/morse_buildroot/output/build/dpp-custom/
make[2]: *** No targets specified and no makefile found.  Stop.

As you could see in the log, buildroot is sticking to the PKG_SRC_DIR
as the makefile source.

Trying to use LIBFOO_MAKE_OPTS (forcing -C xxxx) didn't work either.

Any clue how can I fix this?

Regards,
Bassem

So the configure script is at the root of the source tree, but the main
Makefile is in a sub-directory ?
