OpenWRT should make some check to recognize these libraries: ifneq ($(CONFIG_GCC_VERSION_4_3_X),) define Require/gmp echo 'int main(int argc, char **argv) { return ((__GNU_MP_VERSION*1000+__GNU_MP_VERSION_MINOR)*1000+__GNU_MP_VERSION_PATCHLEVEL)>=004001000?0:1; }' | gcc -include gmp.h -x c -o $(TMP_DIR)/gmptest.o -lgmp - endef $(eval $(call Require,gmp, \ Please install lib gmp >= 4.1.0 \ )) define Require/mpfr echo 'int main(int argc, char **argv) { return (MPFR_VERSION>=MPFR_VERSION_NUM(2,3,0))?0:1; }' | \ gcc -include mpfr.h -x c -o $(TMP_DIR)/a.out -lmpfr - endef $(eval $(call Require,mpfr, \ Please install lib mpfr >= 2.3.0 \ )) endif Unfortunately, this code cannot be performed by prereq-build.mk because we don't know if we need gcc4.3 or not. > > > > My self-answer: This error is caused by the "LD_LIBRARY_PATH" that I > > defined into rule.mk.

The solution should be to link statically libgmp and libmpfr to gcc cross-compiler... but How can I say this to the gcc configure? Furthermore I chosen to avoid to compile the mpfr and gmp into the OpenWRT environment... Now I have an error during the gcc-final regarding ctype_base<char>...
