Package: wx-common Version: 3.0.4+dfsg-7 wxrc (command line compiler for wxWidgets XML resources) binary is installed in /usr/bin. This blocks installing the same package with different architecture - required for cross compile. This can be moved to /usr/lib/<triplet> as described at https://wiki.ubuntu.com/MultiarchCross#Executables_in_-dev_packages.
I'm trying to install this on an amd64 host: apt-get install libwxgtk-webview3.0-dev:armhf wx-common
