You also need to be able to find the gmp headers. Usually a "make install"<br>
after cross compile installs those somewhere in your toolchain</blockquote><div> </div><div><font class="Apple-style-span" color="#3366FF">Yes. You are right I have not run make Install. Can you please more specific about location I should specify while running make install.</font></div>

You left out the line from CROSSCOMPILE that adds the include file search<br>
path, eg:<br>
<br>
export USERCOMPILE="-Wl,-elf2flt -DCOMPILER_HAS_NO_PRINTF_LIKE -O3 -g ${PORTDEFI<br>
NE} -I$PREFIX/arm-elf/inc -L$PREFIX/lib/gcc-lib -DGCC_LINT -DLEAK_DETECTIVE -Dli<br>
nux -D__linux__"<br>

In this case the gmp.h and other headers was installed in $PREFIX/arm-elf/inc<div class="im"><br></div></blockquote><div><font class="Apple-style-span" color="#3366FF">Yes I do have this setting in CROSSCOMPILE.sh </font></div>

It needs the gmp.h from the crosscompile, not the system one.<div class="im"><br>

What's missing is the header files for that ARM architecture, which are<br>
normally installed running "make install" on the cross compiled libgmp.<br><font color="#888888">
