From 4fe6c3c24fbd84fec7d7952a521e0cb443a3d72b Mon Sep 17 00:00:00 2001 From: Cory Fields Date: Tue, 30 Dec 2014 19:10:15 -0500 Subject: depends: major upgrade to darwin toolchain tl;dr: Update to the newer stable toolchain and SDK for OSX without giving up any backwards compatibility. We can move to clang 3.5 as a next step which allows use to use libc++ and the 10.10 sdk, but we'll need to find a build that works in gitian/travis first. Switch to a new, better maintained fork of cctools: https://github.com/tpoechtrager/cctools-port I've forked this and will be working on it some as well: https://github.com/theuni/cctools-port This brings in: cctools v862 ld64: v241.9 It also fixes 64bit builds, so there's no longer any need to use a 32bit clang. Since clang is no longer tied to an old/crusty 32bit build, clang has been upgraded to 3.3. Unfortunately, there's a bug in 3.4 that breaks builds. 3.5 works fine, but there are no binary builds compatible with precise, which is currently used for gitian and travis. We could always build our own if necessary. After updating to stable clang/linker/cctools, it's possible to use a more recent SDK. The current SDK (10.7) through the most recent 10.10 have all been built/tested successfully, both with and without 10.6 compatibility. However, 10.10 requires clang 3.5. SDKs >= 10.9 use libc++ rather than libstdc++. This is verified working as well. --- depends/hosts/darwin.mk | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'depends/hosts') diff --git a/depends/hosts/darwin.mk b/depends/hosts/darwin.mk index 8d718eba17..c1070d8775 100644 --- a/depends/hosts/darwin.mk +++ b/depends/hosts/darwin.mk @@ -1,8 +1,9 @@ OSX_MIN_VERSION=10.6 OSX_SDK_VERSION=10.7 OSX_SDK=$(SDK_PATH)/MacOSX$(OSX_SDK_VERSION).sdk -darwin_CC=clang -target $(host) -mmacosx-version-min=$(OSX_MIN_VERSION) --sysroot $(OSX_SDK) -darwin_CXX=clang++ -target $(host) -mmacosx-version-min=$(OSX_MIN_VERSION) --sysroot $(OSX_SDK) +LD64_VERSION=241.9 +darwin_CC=clang -target $(host) -mmacosx-version-min=$(OSX_MIN_VERSION) --sysroot $(OSX_SDK) -mlinker-version=$(LD64_VERSION) +darwin_CXX=clang++ -target $(host) -mmacosx-version-min=$(OSX_MIN_VERSION) --sysroot $(OSX_SDK) -mlinker-version=$(LD64_VERSION) darwin_CFLAGS=-pipe darwin_CXXFLAGS=$(darwin_CFLAGS) -- cgit v1.2.3
