Undefined symbols for architecture x86_64

Hi and welcome to devnet,
What project are you trying to build ?
-
a cryptocurrency wallet, kinda like bitcoin, i can compile these wallets if they are qt4 with no issues but the last maybe 2 or 3 years when i try to do wallet made with qt5 i get the above error
-
Growl notification support through Apple Script has been removed as all current version of macOS provide support for the notification center and AFAIR, Qt uses that.
In any case, that was macOS specific code that would have been used in the corresponding QPA so you would likely have not had direct access to it anyway.
If you really want to use that function, you should copy it into your project but it would be more interesting to update the code that uses it to use the notification center.

@SGaist i found a fix for it and got past it but now i am getting a new issue with a different project but thats boost and not qt but thanks for all your help!
-
maybe y'all can help me with a quick non qt question the issue i am having with compiling with boost is something about the compiler being outdated and is not compiling C++11 how do i fix it so i can compile C++11? i know gcc is 4.2.1 on my mac but other than that i dont know what i need
-
gcc 4.2.1 ?
If that's really the case then you have something off with your Mac development setup. Xcode has been using clang for several versions now which is handling even more recent versions of the C++ standard.
What does
clang --versionreturn ? -
clang shows up as 9.1.0 but i switched it to clang in qt and i still get the boost error
-
Can you show your .pro file ?
-
sure here you go

thank you very much for your help!
