From d095fbb13e4e91a336ef6af6721ef8012b0a928c Mon Sep 17 00:00:00 2001 From: Peter Simons Date: Wed, 6 Oct 2010 10:29:45 +0000 Subject: [PATCH] pkgs/development/libraries/pcre: fixed build on Darwin The gcc version used on Darwin crashes while compiling the C++ interface of PCRE. Building that code with -O0 avoids the crash. svn path=/nixpkgs/trunk/; revision=24107 --- pkgs/development/libraries/pcre/default.nix | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/pkgs/development/libraries/pcre/default.nix b/pkgs/development/libraries/pcre/default.nix index fba3844bf8e4..1dd860aeaeb1 100644 --- a/pkgs/development/libraries/pcre/default.nix +++ b/pkgs/development/libraries/pcre/default.nix @@ -8,10 +8,14 @@ stdenv.mkDerivation { sha256 = "1zsqk352mx2zklf9bgpg9d88ckfdssbbbiyslhrycfckw8m3qpvr"; }; + # The compiler on Darwin crashes with an internal error while building the + # C++ interface.
