Minimum OS version to run apps made with Cocoa
« on: March 31, 2020, 04:37:45 pm »
What is the minimum MacOS version to run apps made with Lazarus Cocoa widgetset?
I have tested my app on Mojave, but wonder if it would run on previous versions.
Especially since I use AudioQueue to input the Mic.

As far as I can find out they run well on macOS 10.12 Sierra (and, of course 10.13 High Sierra, 10.14 Mojave and 10.15 Catalina), but they don't run on macOS 10.6 Snow Leopard. I am not sure about the versions in between.

Cocoa widgetset code is macOS 10.6 compatible.

However, when compiling on a newer macOS, it might be necessary to specify compatibility framework during linking the project.

By default, the linker uses the "current" macOS system.
Meaning a project compiled on a certain macOS version will run on the version, and likely will run on future versions.

Yet, it's not guaranteed to run on previous macOS versions.

How do we do that?

try to add "-WM10.6" to your FPC command-line parameter.
(which specifies the minimal macOS version to 10.6)

IF it doesn't work you, you might need to explicitly specify SDK folder . (SDK folder will look like /Developer/SDKs/macOS10.6.sdk) using "-XR" parameter. as well as "-FD" for utility binaries (pretty much the linker)
