Hi, Do you mean you have two different executable started ?

Thanks for the feedback and link !

@rggarcia said in Qt 5.8 installation - MacOS Sierra: qtpcre_debug Looks like qtpcre_debug was not built. Did you have any errors while compiling? Do you have to build Qt by yourself?

Hi, You can react on the QGuiApplication:: applicationStateChanged signal.

Thank you @SGaist. Sorry for this stupid mistake. I'll try with this and compile QT on mac. Thanks again

Hi everyone! I'm found the solution of my problem with cross compilation on OS X. The solution is MXE. Here is script to install: #install all need tools using home brew. brew install autoconf automake coreutils gdk-pixbuf gettext gnu-sed gnu-tar intltool libtool p7zip wget xz #install scons tool ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null brew install scons mkdir mxe && cd mxe #install mxe git clone https://github.com/mxe/mxe.git . export PATH=$PATH:/usr/local/opt/gettext/bin #install qt 5 for windows 32 bit by default. make EXCLUDE_PKGS='gsoap' qt5 After install you will need to add compiler to QtCreator. Also add path to MXE bin folder: <path_to_mxe_foler>/usr/x86_64-apple-darwin16.1.0/bin <path_to_mxe_foler>/usr/bin Thats it! Now I test it on my project and let you now about results.
