Build error Qt Declarative

kickoune103

i have compiling for raspberry pi 2 from 5.8 archive.
i follow wiki raspberry beginner

first error build qt5base
error: function ‘QXmlAttributes::QXmlAttributes(QXmlAttributes&&)’ defaulted on its first declaration with an exception-specification that differs from the implicit declaration ‘QXmlAttributes::QXmlAttributes(QXmlAttributes&&)’

I opened the /qt5/qtbase/src/xml/sax/qxml.h file and removed and changed:
QXmlAttributes(QXmlAttributes &&) Q_DECL_NOTHROW = default

to

QXmlAttributes(QXmlAttributes &&) = default

==> solve

now, i have compiling qt base, qtimageformats qtsvg qtsbackend (not found), qt script ok , qt xmlpatterns,

but qt declarative error in make

qmake:

Hi,

Looks like you have a problem with the compiler itself. Which version are you using ?

kickoune103

gcc 4.7 linaro rpi gnueabihf , i have compiled 5.6 with this.

jsulm

@kickoune103 For Qt 5.8 you need at least GCC 4.8, see https://doc.qt.io/qt-5/supported-platforms-and-configurations.html

kickoune103

i have KUBUNTU 16.04 64 bits.
in wiki beginner use for compile this linaro 4.7 or in supported plasform 4.6.3 for qt5.6
i don't understand, is not target os dependent?

for 5.8 GCC 4.8.2...

other tuto use the toolchain
https://github.com/raspberrypi/tools

why fixQualifiedLibraryPaths not work? prefer use sysroot-relativelinks.py

what is the toolchain to use?
