* OpenSSL: force the "1.0.0" soname when loading OpenSSL 1.05.6Giuseppe D'Angelo2018-10-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Linux distributions patch OpenSSL's soname, making builds on such distributions not deployable elsewhere. The problem is that the code loading OpenSSL symbols would attempt to use the soname of the build machine, and therefore not finding the OpenSSL libraries on the deploy system. The binary builds of Qt for Linux are affected by this problem, as they build under RHEL7.4 which changes to soname of OpenSSL to a non-standard string. This makes the binary builds not pick up OpenSSL 1.0 from the machine where the build gets installed on. Given that in the pre-1.1 versions only the 1.0 series is supported, bump the minimum requirement of Qt to that. The 1.0.x releases (up to 1.0.2, at the time of this writing) have kept binary compatibility, and advertise a soname of "1.0.0", which is used by most distributions. So, if loading of OpenSSL with the build-time soname fails, try to load them with the "1.0.0" hardcoded soname. [ChangeLog][QtNetwork][SSL] OpenSSL >= 1.0 is now required to build Qt with OpenSSL support.

* Enable GL prototypes with recent Khronos headersLaszlo Agocs2016-11-103-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | Recent Khronos headers decided to break the world by guarding all function prototypes with GL_GLEXT_PROTOTYPES which has traditionally been used for extension headers only. Until this gets corrected - see https://lists.freedesktop.org/archives/mesa-dev/2016-September/128654.html - add the define to the config tests and qopengl.h. While 5.7 already has some of the qopengl.h fixes due to an upgraded ANGLE shipping with newer headers, this is a cross-platform issue that will surface everywhere eventually. Therefore we target the full set of fixes to 5.6. This time we also make sure the forced define of GL_GLEXT_PROTOTYPES is removed before including the ext header, thus apps get the ext protos only if they actually requested them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In addition to the proprietary Mali Linux driver bundle from ARM, there are a couple of semi open source alternative bundles out in the wild, which are mostly derivatives from the sunxi-mali bundle. The non-ARM bundles lacks the proprietary header file fbdev_window.h which defines the fbdev_window struct. Instead, it has an equivalent mali_native_window struct in the EGL/eglplatform.h (which in turn is included by EGL/egl.h). This change adds an alternative configure test which detects the non-ARM bundles are used. It also removes the dependency on fbdev_window.h by defining the structure ourselves, which actually makes the plugin potentially compilable with *any* EGL SDK.

* | Auto-detect whether 64-bit std::atomic really worksThiago Macieira2015-09-222-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The C++ standard says it must, but some badly-configured toolchains seem to be lacking support. In particular, for some 32-bit platforms without native support for them, GCC implements 64-bit atomics via out-of-line functions in libatomic. If that library is missing... well, then std::atomic 64-bit doesn't work and we mustn't try to use it. This was found when trying to compile Qt 5.6 for MIPS 32-bit: Linking library libQt5Core.so.5.6.0 .obj/qsimd.o: In function `std::__atomic_base<unsigned long long>::load(std::memory_order) const': /opt/poky/1.7/sysroots/mips32r2-poky-linux/usr/include/c++/4.9.1/bits/atomic_base.h:500: undefined reference to `__atomic_load_8' .obj/qsimd.o: In function `std::__atomic_base<unsigned long long>::store(unsigned long long, std::memory_order)': /opt/poky/1.7/sysroots/mips32r2-poky-linux/usr/include/c++/4.9.1/bits/atomic_base.h:478: undefined reference to `__atomic_store_8' Yocto bug report: https://bugzilla.yoctoproject.org/show_bug.cgi?id=8274 Change-Id: I42e7ef1a481840699a8dffff140224d6614e5c36 Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@theqtcompany.com> Reviewed-by: Lars Knoll <lars.knoll@theqtcompany.com> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* | Add detection of C++14 and C++1z compiler featuresThiago Macieira2015-09-054-0/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ChangeLog][General Improvements] Qt's buildsystem now detects whether the compiler supports C++14 and experimental support for C++1z. If the compiler supports it, then Qt is automatically compiled using that support. \ This does not apply to user applications built using qmake: those are still built with C++11 support only. To enable support for C++14 in your application, add to your .pro file: CONFIG += c++14 (similarly for C++1z).

* | Fix pointer size detection when cross-compilingLaszlo Agocs2015-08-211-1/+4
| | | | | | | | | | | | | | | | | | | | | | The initial configure fails to build the pointer size test correctly due to the missing --sysroot argument. This breaks 64-bit targets as the pointer size is set to 4. A subsequent configure correctly builds and picks 8 up, but we expect the first attempt to work as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will automatically add DirectWrite support if the required headers are found. The note about platform support from the help screen has also been removed, since Windows XP is not officially supported. Applications that need to run on XP can still build with -no-directwrite. Also changed the configure test to be a proper compile test, since cross-compiled builds for Windows CE may break otherwise.
