Problem of Qt 5.6.0 Cross Compile for Olimex A20 Micro With Debian Jessie?

jsulm

Well, the errors you see just tell you that some things will not be available (for example ICU or libproxy). Whether this is an issue depends on your needs. If you do not need any of them then you can just continue with make.

If you need any of these you have ot install headers and libs.
C++14 is not available because your compiler does not support it.
SSE2 is not supported because your target CPU is not an Intel CPU.

Thanks jsulm,
I dont know whether how many out of 18 disabled things I do not need in future.
Means As I can see Mysql or SQLite2 in disabled list.
If I continue 'make' with errors which I seen when ./configure...command.
& In future if I want to create QT application which use those Mysql or SQLite2 etc things...then?

jsulm

Then you will need to rebuild at least parts of Qt later

Thanks jsulm,
I found

Turn on verbose messaging (-v) to ./configure to see the final report.
If you believe this message is in error you may use the continue
switch (-continue) to ./configure to continue.

So I use ' -v -continue' in ./configure command, Then run command:-

make -d -j4

I got error as follows:-

Live child 0x00ab0210 (.obj/qlatincodec.o) PID 14536 
Reaping losing child 0x00ab0210 PID 14536

Any help?

jsulm

Are there any other messages before?

Mandar Khire

Yes there are lots (huge log due to '-d' option in 'make') of

g++: error: unrecognized command line option ‘-std=c++14’

jsulm

For some reason -std=c++14 compiler option was passed to the compiler. Your GCC version does not support it. Actually in your previous post it was stated that C++14 was disabled. So, I'm wondering why this flag was passed to the compiler. You can check whether it is possible to specify which C++ standard should be used when you call configure (configure -h).

Mandar Khire

Thanks jsulm,
I found '-std=c++14' in following files

/qt-everywhere-opensource-src-5.6.0/qtbase/mkspecs/common/g++-base.conf has

QMAKE_CXXFLAGS_CXX11    = -std=c++14

qt-everywhere-opensource-src-5.6.0/qtbase/src/tools/bootstrap/Makefile has

CXXFLAGS      = -pipe -ffunction-sections -O2 -fPIC -std=c++14 -fno-exceptions -Wall -W -D_REENTRANT $(DEFINES)

Steps taken:-

After ./configure command I run make command & got error.
After it I run make clean.

Qustion:-

Is my ./configure command wrong?
My configure command as below:-

./configure -v -continue -opengl es2 -device linux-a20olimex-g++ -device-option CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- -sysroot /mnt/a20 -opensource -confirm-license -optimized-qmake -release -make libs -prefix /usr/local/qt5a20 -no-pch -nomake tests -no-xcb -eglfs -v -tslib -dbus -icu -pulseaudio -glib -no-cups -qt-harfbuzz -gtkstyle

Should I edit those two files where I found c++14?
What about other disable things? Previously I found 18 things as disable but after make clean & might due to -v option in ./configure command I found more things as disabled which as below:-
1 to 18 in first question I mentioned.
19. PulseAudio
20. OpenGL ES 3.0
21. OpenGL ES 3.1
22. libudev
23. xkbcommon
24. GBM
25. KMS
26. Mir client
27. EGL-X11
28. eglfs-brcm
29. eglfs-egldevice
30. eglfs-mali
31. eglfs-viv
32. OpenVG
33. OpenVG (lc includes)
34. alsa

Need Guidance!
Thanks,

jsulm

You can try to replace

QMAKE_CXXFLAGS_CXX11    = -std=c++14

with

QMAKE_CXXFLAGS_CXX11    = -std=c++11

in qt-everywhere-opensource-src-5.6.0/qtbase/mkspecs/common/g++-base.conf
And then run configure and make again.

Regarding other disabled things: it really depends on your needs. Do you need any of them? If not then just build. If you need any of them then you need to make sure you have header files and libraries needed to use them.

Mandar Khire

Thanks jsulm,
I change g++-base.conf as per instructions.
Then I run 'make' command.
There are errors while make command run.
