Build error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC0.8.0

[Shree Kantha]

HI Team,

I am hitting below error when compiling ONL. Please help.

I am using UBUNTU to build and have installed (libmpfr-dev, libgmp-dev,gmpc-dev). Am I missing anything here. thanks in advance.

checking for the correct version of gmp.h... yes

checking for the correct version of mpfr.h... yes

checking for the correct version of mpc.h... no

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.

Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify

their locations.  Source code for these libraries can be found at

their respective hosting sites as well as at

ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also

http://gcc.gnu.org/install/prerequisites.html for additional info.  If

you obtained GMP, MPFR and/or MPC from a vendor distribution package,

make sure that you have installed both the libraries and the header

files.  They may be located in separate packages.

Hi Shree,

Thanks for the mail.  My guess is that the buildroot dependency is going to be a pain to compile with any other compiler than what's shipped with the docker image.  That said, it's completely orthogonal to the rest of the system so you can build that with one compiler and the rest of the system with your new compiler.  The buildroot tools go into the initrd image that's part of the ONL loader.  Probably the easiest thing to do is to compile the $ONL/components/$(ARCH)/initrd-$(ARCH) package with the existing 3.x compiler so that it's cached into $ONL/debian/repo/$(ARCH) and then build everything else that you want with the new 4.x compiler.

Or, better yet, just download it from the initrd package from the apt repo:  http://apt.opennetlinux.org/debian/dists/unstable/main/binary-amd64/initrd-amd64_0.1.0bsn1~ubuntu1_amd64.deb

and manually put it in $ONL/debian/repo/amd64 (assuming you're building an amd64 targetted machine).

Please let me know if that makes sense,

- Rob
