This patch fixes compilation on Solaris 10 platform which provides GNU C 3.4.3 by default by removing unsupported -ftree-vectorize option. This may penalize Solaris 11, where GNU C 4.6.2 is provided but current cabal does not support OSes version detection and Solaris 10 is still supported (by Oracle) and will be at least till 2021 so let's support it too. --- primitive.cabal | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/primitive.cabal b/primitive.cabal index b819e03..666a8f2 100644 --- a/primitive.cabal +++ b/primitive.cabal @@ -44,7 +44,9 @@ Library Install-Includes: primitive-memops.h includes: primitive-memops.h c-sources: cbits/primitive-memops.c - cc-options: -O3 -ftree-vectorize -fomit-frame-pointer -Wall + cc-options: -O3 -fomit-frame-pointer -Wall + if !os(solaris) + cc-options: -ftree-vectorize if arch(i386) || arch(x86_64) cc-options: -msse2 -- 1.8.1.4
