error building showcase in mac

[vrescobar]

Hello, I tried to compile the showcase in mac and doesn't work at all, I followed all the instructions for the setup (with latest hxcpp from git recompiled as the instructions say).

hxcpp=3.4.0 wxwidgets 3.0.2_4 MacOs version 10.12.4

Any idea on where to start debugging this? How could I provide more information?

If I try to build another simple project (using haxeui2-hxwidgets) I get the exact same error so I guess the problem might be in hxwidgets.

Here is the output for haxe build.hxml:

Yeah, the right step is to start with hxWidgets, but im not 100% the best way to debug this, i dont have a mac, just a VM and its really old. Is there anything else on this issue list that might help?

@sumo961?

https://github.com/haxeui/hxWidgets/commit/a640921b4f304c044ee8baf90c372606d6b24cb8 should have fixed this.

Could you retest?

I updated to the latest version, deleted the previous build and recompiled.... but unfortunately I still get an error:
