Building "fw_printenv" for the target works with make, i.e.: $ git rev-parse HEAD 524123a70761110c5cf3ccc5f52f6d4da071b959 $ head Makefile | grep -E 'VERS|PATCH|SUB' VERSION = 2014 PATCHLEVEL = 07 SUBLEVEL = $ export CROSS_COMPILE=arm-linux-gnueabi-;export ARCH=arm $ . /opt/eldk-5.4/armv7a/environment-setup-armv7a-vfp-neon-linux-gnueabi $ make nitrogen6q_config Configuring for nitrogen6q - Board: nitrogen6x, Options: IMX_CONFIG=board/boundary/nitrogen6x/nitrogen6q.cfg,MX6Q,DDR_MB=1024 $ make env GEN include/autoconf.mk.dep GEN include/autoconf.mk HOSTCC scripts/basic/fixdep HOSTCC tools/env/aes.o HOSTCC tools/env/crc32.o HOSTCC tools/env/ctype.o HOSTCC tools/env/env_attr.o HOSTCC tools/env/env_flags.o HOSTCC tools/env/fw_env.o HOSTCC tools/env/fw_env_main.o HOSTCC tools/env/linux_string.o HOSTLD tools/env/fw_printenv_unstripped STRIP tools/env/fw_printenv $ file tools/env/fw_printenv tools/env/fw_printenv: ELF 32-bit LSB executable, ARM, version 1 (SYSV), \ dynamically linked (uses shared libs), for GNU/Linux 2.6.16, \ BuildID[sha1]=0x50da78ea86f3dc1a5a83529da21206f9a46fc93b, stripped If you need more verbose make output to check which compiler and options are used for building, run $ make V=1 env > If I'm understanding you, what you're saying here is that > tools/env/README is in error and that the directory has now lost the > ability to cross compile and can now /only/ build native. Is that correct? s. above. cross-building works also, provided you configured building for the target first (i.e. "make nitrogen6q_config" step above).
