mpfr and gmp packages #1

Open oakad opened 14 years ago

libgmp may be required by openssl and newer versions of gcc. libmpfr is used by newer versions of gcc.

When hosting cross-compilers on a network share, it is convenient to update them all in one go. Some of the machines connecting to the share run x86 OSes, so cross-compilers must be built in two flavors (amd64 and x86) for each target. Unfortunately, newer gcc requires libmpfr and libgmp to build, and those are not provided either by emul-linux-x86 or this overlay.

I shall also add, that for unknown reason gmp tends to specify certain sizes explicitly in its include files, depending on a build ABI. Therefore, its include files can not be perused for multi-abi builds unchanged as they are - some patching of those is required.

The worst consequence of the above is that everything compiles fine and then fails with nasty run-time errors.

The header issue is not really a problem if the installed headers are wrapped for multilib.

I'll see about getting mpfr and gmp into multilib-master...

I need dev-libs/gmp for mit-krb5 and openssl. Please add it.
