Makefile.cross_compile or Makefile.cross might suit better Could you provide more details help/doc on how to use it and what it's actualy doing? > $ make ARCH=arm CROSS_COMPILE=arm-linux- LDFLAGS="-static" > > Auto-detecting system features: > ... dwarf: [ on ] > ... glibc: [ on ] > ... gtk2: [ OFF ] > ... libaudit: [ on ] > ... libbfd: [ on ] > ... libelf: [ on ] > ... libnuma: [ OFF ] > ... libperl: [ OFF ] > ... libpython: [ OFF ] > ... libslang: [ on ] > ... libunwind: [ on ] > ... libdw-dwarf-unwind: [ OFF ] > ... zlib: [ on ] > ... lzma: [ on ] > > Signed-off-by: Rabin Vincent <[email protected]> running the command from changelog failed on my setup, please check attached log jirka --- [jolsa@krava perf]$ make ARCH=arm CROSS_COMPILE=arm-linux- -f Makefile.deps mkdir -p dl && cd dl && wget -N https://people.redhat.com/sgrubb/audit/audit-2.4.4.tar.gz --2015-10-12 13:36:45-- https://people.redhat.com/sgrubb/audit/audit-2.4.4.tar.gz Resolving people.redhat.com (people.redhat.com)... 10.5.19.28 Connecting to people.redhat.com (people.redhat.com)|10.5.19.28|:443... connected.
