Static Install Fails on OSX



  • I'm following the instructions on this page to install a static version of Qt5 on El Capitan. The configure and make commands go through without a hitch, but make install fails (I've tried a couple times starting from scratch). The last message before the error is this

    Any help would be greatly appreciated! I can provide any more details as needed as well, but not sure where to start

    Hi and welcome to devnet,

    You're likely building Qt with Xcode 8 or 8.1.

    Apple did some changes with the 10.12 SDK. You need to clone a more recent version of the QtConnectivity module.



  • Looks that was it, thanks! For anyone coming across in the future, I simply clone the qtconnectivity repository from here, and simply put it in place of the qtconnectivity module in the full codebase. Not sure if that's the proper way, but it seems to have compiled and installed properly
