* Improve the architecture-detection mechanismThiago Macieira2012-05-302-34/+29
| | | | | | | | | | | | | | For the Unix part, this now obeys the -v option, printing the full command-line it used to compile, allowing testers to identify why something went wrong. Unfortunately, it requires a full compilation cycle, instead of just preprocessing. Just one more among the many on Unix, but maybe a noticeable slow-down on Windows.

* Ensure that qXXXdetection.h can be included directlyThiago Macieira2012-04-211-0/+1
| | | | | | | | | Those files might have dependency on one another, on qconfig.h and on early qglobal.h definitions, so ensure that the only correct include order is that of qglobal.h. Change-Id: I89098bacaf16353ee8b51604ee885508dc8e201a Reviewed-by: Olivier Goffart <ogoffart@woboq.com>
* Make architecture detection more robust.Girish Ramakrishnan2012-03-222-15/+15
| | | | | | | | | Any message/error in mkspecs or qmake feature files ends up confusing the current arch detection logic. Instead, search for "Project MESSAGE: .* Architecture: <arch>".

* arch: Undefine possible architecture definesHolger Hans Peter Freyther2012-03-161-0/+13
| | | | | | | | | | | | | Some compilers define the architecture to one leading to detecting '1' as target architecture. Always undef the architecture name. Compilers: gcc version 4.6.3 (Debian 4.6.3-1) has '#define i386 1' gcc version 4.5.3 (Broadcom stbgcc-4.5.3-1.3) has '#define mips 1' Change-Id: I7af1bb743579be472467c74e6c08638648823ef3 Reviewed-by: Girish Ramakrishnan <girish.1.ramakrishnan@nokia.com> Reviewed-by: Bradley T.

* Remove -arch argument and #define QT_ARCH from configuresBradley T. Hughes2012-03-132-0/+77
Do not try to detect the host or target architectures using uname or similar, and do not override with the -arch or -host-arch configure arguments. The configures will still accept the -arch and -host-arch arguments, but it ignores them and instead outputs a warning stating that these arguments are obsolete and should not be used. Set QT_ARCH and QT_HOST_ARCH qconfig.pri variables based on the compiler target. This is done by running qmake (twice when cross-compiling) on config.tests/arch/arch.pro, which preprocesses a file that contains all knowns processors. On Windows, configure.exe has never run any config.tests before, and does not currently have a function to run a program and capture its output. Use _popen() to accomplish this (as qmake does for its system() function). This needs to be done after qmake is built, as does the mkspecs/qconfig.pri generation. As a side effect, the configure steps have been slightly re-ordered, but the overall result is the same. The displayConfig() call is moved to just before generating Makefiles, so that it can show the detected architecture(s).
