I added the following into $(TOP)/rule.mk (and I don't like what I
do...):
export LD_LIBRARY_PATH=$(TOP)/staging_dir/host/lib:$(LD_LIBRARY_PATH)
Anyway I decided to change approach: install directly on the host
environment the GMP and MPFR library need to GCC4.3 compiler... OpenWRT
should make some check to recognize these libraries:
ifneq ($(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.

I would patch OpenWRT as little as possible, of course. 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>...
Thanks and Best regards,
