Subject: [PATCH] Release 1.0.1 of GNU MPC
Date: Tue, 11 Dec 2012 23:02:35 +0100 [thread overview]
Message-ID: <201212112302.35675.andreas@enge.fr> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 546 bytes --]
Patch attached.
Unfortunately, I could not test it yet, since guix-package starts by
building path(s) `/nix/store/9syafc8xvscaywjldyszzgkc8pljwpj6-gcc-cross-
boot0-4.7.2'
although gcc-4.7.2 (without "coss-boot") is already there. How come?
The previous mpc release built without problem without re-downloading gcc.
Actually, the same holds for the unmodified mpfr - after changing the
definition of mpc in multiprecision.scm, installing mpfr also starts by
redownloading gcc.
Is it related to the dependency of gcc on mpfr and mpc?
Andreas
