[Valgrind-users] Query regarding valgrind build for Octeon MIPS 64 using cross compiler.

[MUHAMMADSAHEER C <sah...@sa...>]

Hi,
I am trying to build valgrind for Octeon MIPS 64 architecture using cross compiler. 
While linking, build gives following error,
m_main.c:(.text+0xc): undefined reference to `_gp_disp'
Can anyone suggest how to resolve this?
I searched in net, but could not find a proper solution.
I used following configuration options
--host=mips-linux-gnu  -with-float=hard  --with-arch-64=5kc --with-gnu-as --with-gnu-ld CFLAGS="-march=octeon2 -msoft-float -Wall -mabi=64 -G 0 -fPIC -mips64r2 -mplt" 
If you can give detailed configuration option or fix for this issue, it will be very helpful.
Best Regards,
Muhammad Saheer.C

Use, --host=mips64-linux-gnu to build for MIPS64

--with-arch-64=5kc --with-gnu-as --with-gnu-ld -> these are 
unrecongnised options. Remove them.

Also, do not specify "-march=octeon2" in CFLAGS, though your target is 
octeon2.

Hope these changes would fix the build.
