Qt 5.13.1 for raspberry pi CM3: "#include<random>" build error

Hello everyone!
I'm trying to cross-compile qt 5.13.1 for raspberry pi3 (CM3) but I these problems:qt-everywhere-5.13.1/qtbase> ./configure -release -opensource -confirm-license -no-use-gold-linker -c++std c++17 -opengl es2 -make libs -no-gbm \ -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/raspi-qt/gcc-linaro-7.4.1-x86_64_armv8l-linux-gnueabihf/bin/armv8l-linux-gnueabihf- \ -sysroot ~/raspi-qt/raspbian-sysroot -prefix /opt/qt5 -extprefix ~/raspi-qt/qt5-pi -hostprefix ~/raspi-qt/qt5-tools \ -skip qt3d -skip qtandroidextras -skip qtdatavis3d -skip qtmacextras -skip qtpurcheasing -skip qtwebchannel -skip qtwebengine -skip qtwebplugin -skip qtwebview -skip qtscript -skip qtwinextras -skip qtx11extras -nomake examples -nomake tests -no-compile-examples ...bla bla bla...

I have followed this tutorial but using the linaro toolchain 7.4.1 for armv8l. The original raspbian toolchain gives me the same errors.
What ca I do?
Many thanks! -

@jsulm how can activate c++11?
When I perform the second compilation (without -c++std) the configure process gives:Building on: linux-g++ (x86_64, CPU features: mmx sse sse2) Building for: devices/linux-rasp-pi3-g++ (arm, CPU features: neon) Target compiler: gcc 9.2.1 Configuration: cross_compile enable_new_dtags largefile neon precompile_header shared rpath release c++11 concurrent dbus reduce_exports stl Build options: Mode ................................... release Optimize release build for size ........ no Building shared libraries .............. yes Using C standard ....................... C11 Using C++ standard ..................... C++11 Using ccache ........................... no Using new DTAGS ........................ yes Using precompiled headers .............. yes Using LTCG ............................. no Target compiler supports: NEON ................................. yes Build parts ............................ libs
so I think that c++11 is activated... Is it true?

@dxvx said in Qt 5.13.1 for raspberry pi CM3: "#include<random>" build error:

Looks like it is, yes
