The INSTALL file says:

= start =
To cross compile, you must specify the correct variables:

1. When running configure (CC, CXX, CXXFLAGS, LDLIBS, etc).
2. Manually edit include/mk/config.mk, as described in Configuration.

Note: Do not specify variables on the command-line. Use config.mk instead.
= end =

I copied include/mk/config.mk.default to include/mk/config.mk and edited include/mk/config.mk to include the my cross-compile variables:

CROSS_COMPILE :=
SYSROOT := --sysroot=
CC := $(CROSS_COMPILE)gcc $(SYSROOT)
LD := $(CROSS_COMPILE)ld $(SYSROOT)

I then ran "./configure --host=x86_64-linux-gnu --prefix=/nobackup/awardak/ltp/ltp-full-20140115/build/" and it overwrote my config.mk changes above.

How do I properly set my cross compilation env?

Thanks,
