-
Hi Everyone,
I am attempting to cross compile Qt 6.5.0 for qnx 7.1.0. I am following the following guide:
https://doc.qt.io/qt-6/building-qt-for-qnx.htmlmy cross compile command is as follows:
cmake -GNinja -DCMAKE_TOOLCHAIN_FILE=/home/matt/qnx.cmake -DQT_HOST_PATH=~/qt6Host -DCMAKE_INSTALL_PREFIX=~/qnx_install ~/qtbasewith qtbase contain the 6.5.0 branch of the repo
I am getting the following output from this command:

I am rather lost at the moment so any suggestions would be welcome.
Thanks!
