From ea6dda58c8e9f532671b72eebd95256228c2b179 Mon Sep 17 00:00:00 2001 From: Lucas Dutra Nunes Date: Wed, 30 Oct 2013 15:46:26 +0000 Subject: [PATCH] linux-fslc: kernel build now needs GNU bc to work The kernel now needs to use GNU bc to be built since version 3.9. The following commit message from the kernel explains the reason: commit 70730bca1331fc50c3caacaea00439de1325bd6e Author: H. Peter Anvin Date: Thu Feb 14 15:13:55 2013 -0800 kernel: Replace timeconst.pl with a bc script bc is the standard tool for multi-precision arithmetic. We switched to Perl because akpm reported a hard-to-reproduce build hang, which was very odd because affected and unaffected machines were all running the same version of GNU bc. Unfortunately switching to Perl required a really ugly "canning" mechanism to support Perl < 5.8 installations lacking the Math::BigInt module. It was recently pointed out to me that some very old versions of GNU make had problems with pipes in subshells, which was indeed the construct used in the Makefile rules in that version of the patch; Perl didn't need it so switching to Perl fixed the problem for unrelated reasons. With the problem (hopefully) root-caused, we can switch back to bc and do the arbitrary-precision arithmetic naturally. Signed-off-by: H.
