mingw-qt5-qtbase fails to build on non-x86 arches with

Because qt5-qtbase builds the qstring.cpp file correctly (checked on s390x) I guess the cross-build system wrongly expects it runs on x86. The problem exists at least on s390x and ppc.

Comment 1 Erik van Pienbroek 2013-01-30 08:44:58 EST
This piece of output looks suspicious:

g++  -o arch arch.o

    Found architecture in binary

Now investigating why the configure script can't determine the host architecture for s390x..
Comment 2 Erik van Pienbroek 2013-01-30 08:52:10 EST
Do you happen to have shell access to a s390x environment which I could temporary use for debugging?

all machines I have are internal in RH, but the PPC people have public machines available, please ping them on #fedora-ppc on FreeNode
Comment 4 Erik van Pienbroek 2013-01-30 09:33:26 EST
I'm not sure if the problem also exists on PPC..but then perhaps you could help me with the debugging.

Could you try to build the package locally (using fedpkg local/rpmbuild) and once it fails, please perform the following commands:

$ cd build_release_static_win32
$ g++ -pipe -g -Wall -W -fPIE  -I../qtbase-opensource-src-5.0.0/mkspecs/linux-g++ -I../qtbase-opensource-src-5.0.0/config.tests/arch -I. -o arch.o ../qtbase-opensource-src-5.0.0/config.tests/arch/arch.cpp -o arch
$ strings ./arch

The Qt5 configure script tries to locate the following text in the output of the 'strings' command:
==Qt=magic=Qt== Architecture
==Qt=magic=Qt== Sub-architecture

During the mock build which you tried earlier these two texts couldn't be located in the output of the 'strings' command.

What output does the 'strings' command give you?
Comment 5 Erik van Pienbroek 2013-01-31 10:51:48 EST
Were you already able to do the test I described in comment 4 ?
Right now I'm prepping an update to Qt 5.0.1 and I would like to fix this bug at the same time as well
Comment 6 Dan Horák 2013-01-31 11:08:58 EST
got distracted by other work, but it's on my list, will try to check it later today
Comment 7 Erik van Pienbroek 2013-01-31 12:20:50 EST
I think I've found the root cause of this issue, but I'm not sure how to fix it. I just filed at bug upstream:
Comment 8 Dan Horák 2013-01-31 12:25:19 EST
Thanks, that corresponds to my understanding what was happening during the non-x86 builds.

Comment 11 Erik van Pienbroek 2013-02-08 12:19:19 EST
I just pushed an updated package to rawhide and f18 which contains a fix which should allow cross-compilation on non-x86 hosts. I did a scratch build of it for the ppc target and it built fine without issues
Comment 12 Dan Horák 2013-02-12 09:42:31 EST
for the record - build on s390/s390x was also successful
