[gtk-osx-users] Hello World with gtk

[David Price <david dcprice ca>]

Hello

I finally managed to use jhbuild to install gtk.  Thanks to John Ralls 
for helping me with the Rust problem.

Now I am trying to do the basic GTK Hello World in Rust from 
"https://gtk-rs.org/gtk4-rs/stable/latest/docs/gtk4/"; and getting the 
following errors :


error: failed to run custom build command for `glib-sys v0.14.0`

process didn't exit successfully: 
`/Users/david/MyStuff/Rust/RustGTK/my-gtk-app/target/debug/build/glib-sys-a2f0018fbdfb445a/build-script-build` 
(exit status: 1)

cargo:warning=Failed to run `"pkg-config" "--libs" "--cflags" "glib-2.0" 
"glib-2.0 >= 2.66"`: No such file or directory (os error 2)


Was I supposed to set up a PATH variable for gtk (which has 
glib-2.68.0)?  If so, how?  Is it looking for glib in .cargo ?

Also, when I run just the build-script-build mentioned above, I get the 
following warning :

    cargo:warning=$CARGO_MANIFEST_DIR not set


If it helps, this is my $PATH

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:~/.dotnet/tools:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Users/david/.cargo/bin:/Users/david/.new_local/bin

I am a newbie at all this, so any patient assistance would be appreciated

    David
