Cory Fields	bb44d9e754	depends: fix a static qt5 crash when using certain versions of libxcb See here for background: https://bugreports.qt.io/browse/QTBUG-34748 libxcb temporarily had an abi breakage which caused crashes when qt was compiled against a non-compatible version. Building qt with -qt-xcb should have shielded us from this issue, except that incompatible headers were used when building qt's wrapper. Make sure those headers aren't picked up by qt's build. Details: qt's build adds a wrapper around the xcb libs when -qt-xcb is used. This is done to avoid having to link to a handful of different libs, which may not be api/abi stable. This build depends on include-order, so that its files are found before the real libxcb headers. Our build (for other reasons related to qt's complicated build-system) injects our prefix into CXXFLAGS. Because libxcb is found in this path, that reverses the include-order, negating the purpose of the wrapper. To fix, libxcb's includes are simply moved to a subdir. pkg-config ensures that they're still found properly when needed. To make things even more interesting, this behavior in qt's .pro files is broken: INCLUDEPATH += $$QMAKE_CFLAGS_XCB The INCLUDEPATH variable is processed by qmake which automatically prefixes each entry with "-I". The QMAKE_CFLAGS_XCB variable comes from pkg-config and already contains -I, making the path look like "-I-I/path/to/xcb/headers". To work around that, CFLAGS/CXXFLAGS are used here rather than INCLUDEPATH.	10 years ago
Cory Fields	4fe6c3c24f	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.	10 years ago
