Re: [gtk-osx-users] Error when compiling gobject-introspection on macOS 10.13

[Jiří Techet <techet gmail com>]

Hi John,

that's strange. I don't need python at all for the project myself and there's no need to bundle it - it's just used when building gobject-introspection. Simple

jhbuild bootstrap && jhbuild build meta-gtk-osx-bootstrap && jhbuild build meta-gtk-osx-core 

used to work fine - now it fails when gobject-introspection starts compiling. I don't know, it may not be because of macOS 10.13 - it could also be because of some recent change in the modules (haven't tried them in the last 2 months).

That’s always been true. Build python as part of your project and include it in the bundle. Note that it needs openssl. Another user found that building both of them before bootstrapping allowed openssl to build and install without manual intervention, but I haven’t been able to get that to work for me.

BTW have you tested your build on a 10.6 system? When I tried to build for 10.6 using the 10.11 SDK it built but crashed when I tried to run on a 10.6 VM.
