Building qt592 32 bit on 64bit ubuntu 1604

[abarmotov]

Hi, im trying to build qt592 32bit on 64bit ubuntu 1604
My configure options are:

pr="/home/user1/bin/qt592_linux32"
src=/home/user1/src/qt-everywhere-opensource-src-5.9.2
logf="conf_run.txt"

$src/configure -platform linux-g++-32 \
-recheck -v -confirm-license -opensource \
-skip webengine -skip websockets -skip webchannel \
-skip 3d -skip connectivity -skip declarative -skip location -skip quickcontrols -skip quickcontrols2 -skip script -skip sensors -skip wayland -skip serialbus \
-skip gamepad \
-no-icu -no-sql-mysql \
-no-compile-examples -nomake examples -no-qml-debug -release -force-debug-info -separate-debug-info \
-no-strip -v \
-prefix $pr 2>&1 | tee $logf

configure worked fine, but then make starts, it failed with error:

...
/qt-everywhere-opensource-src-5.9.2/qtbase/src/corelib/animation/qabstractanimation.h -o .moc/moc_qabstractanimation.cpp
usr/include/c++/5/bits/stl_relops.:67: Parse error at "std"
make[3]: *** [.moc/moc_qabstractanimation.cpp] Error 1
Makefile:2193: recipe for target '.moc/moc_qabstractanimation.cpp' failed
...

Line # 67 In /usr/include/c++/5/bits/stl_relops.h is "namespace std _GLIBCXX_VISIBILITY(default)"

Qt592 64 bit on this machine builded ok

Hi
it might be a moc issue
https://forum.qt.io/topic/27761/moc-parse-error-at-std-workaround

[abarmotov]

Yes, this issue is related
I added "INCLUDEPATH += /usr/include/x86_64-linux-gnu/c++/5/32" in qtbase/mkspecs/linux-g++-32 and build started, but stopped at

/qtbase/src/network/kernel/qdnslookup_unix.cpp:58:0:
/usr/include/gnu/lib-names.h:8:31: fatal error: gnu/lib-names-32.h: No such file or directory

so topic is "fixed", i`ll try to make a bugreport

Hi,

Maybe a silly question but are you sure you properly installed all development packages needed in their 32bit versions ?

[abarmotov]

Hi, yes i dont )
As configure works fine, i thougth i was installed all
But googling again i found https://stackoverflow.com/questions/22359098/compiling-32bits-qt-sources-on-a-64bit-debian-environement and build was successful
So no bug report needed

@abarmotov, Thank you very much! INCLUDEPATH += ... helped.

in my case it was a problem with .qmake.stash file in project directory transferred from other system - maybe can help someone else.
