i686-w64-mingw32 7.3.0 and 6.3.0
Description
When cross-compiling Qt 5.12.0 Alpha using i686-w64-mingw32 7.3.0 as provided by Ubuntu 18.04 (as well as Debian Testing & Unstable), the cross-compilation fails due to Qt source code causing an internal error in the MinGW compiler. This is also reproducible using i686-w64-mingw32 6.3.0 as provided by Debian Stretch (Stable). This is not reproducible using 7.3.0 and 6.3.0 x86_64-w64-mingw32 – the 64-bit MinGW.
The build error:
global/qrandom.cpp: In function 'qsizetype qt_random_cpu(void*, qsizetype)': global/qrandom.cpp:121:1: internal compiler error: in ix86_compute_frame_layout, at config/i386/i386.c:12793 } ^ Please submit a full bug report, with preprocessed source if appropriate. See <https://gcc.gnu.org/bugs/> for instructions. make[4]: *** [Makefile.Release:12868: .obj/release/qrandom.o] Error 1 make[4]: *** Waiting for unfinished jobs.... make[4]: Leaving directory '/build/qt-everywhere-src-5.12.0-alpha/qtbase/src/corelib' make[3]: Leaving directory '/build/qt-everywhere-src-5.12.0-alpha/qtbase/src/corelib' make[3]: *** [Makefile:36: release] Error 2 make[2]: *** [Makefile:220: sub-corelib-make_first] Error 2 make[2]: Leaving directory '/build/qt-everywhere-src-5.12.0-alpha/qtbase/src' make[1]: *** [Makefile:45: sub-src-make_first] Error 2 make[1]: Leaving directory '/build/qt-everywhere-src-5.12.0-alpha/qtbase' make: *** [Makefile:44: module-qtbase-make_first] Error 2
To reproduce, run the attached build_qt.sh script on Ubuntu 18.04 as root with i686 as the argument:
./build_qt.sh i686
If you prefer using Docker:
mkdir build mv build_qt.sh build sudo docker run --rm -v "$PWD/build":/build ubuntu:18.04 /bin/bash /build/build_qt.sh i686
