Unable to compile on OSX.

[ghost]

I am trying to compile howl on MacOS Mojave. However I get a persistent error whenever I try to compile from source.

I ran the below commands.

$ brew update
$ brew install glib

I received the below output.

==> Pouring glib-2.60.6.mojave.bottle.tar.gz
🍺  /usr/local/Cellar/glib/2.60.6: 429 files, 15.2MB

I take it that this means that glib was installed on my machine. Here is my $PATH.

/Users/sanjayadhith/.opam/default/bin:/usr/local/opt/qt/bin:/usr/local/opt/ruby/bin:/Users/sanjayadhith/.cargo/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:/Library/Frameworks/Mono.framework/Versions/Current/Commands

However, when I tried to compile the howl text editor I persistently get this error message despite running brew doctor and brew reinstall glib.

Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable

I also opened up an issue at homebrew-core to see if the problem was at the homebrew end.

I managed to compile on MacOS Catalina:

• First change src/Makefile (just add glib-2.0):

  
  diff --git a/src/Makefile b/src/Makefile
  index a9e21430..014d116f 100644
  --- a/src/Makefile
  +++ b/src/Makefile
  @@ -3,7 +3,7 @@ UNAME_S := $(shell uname -s)
  
  GTK = gtk+-3.0
  GTK_CFLAGS = $(shell pkg-config --cflags $(GTK))
  -GTK_LIBS = $(shell pkg-config --libs $(GTK) gmodule-2.0 gio-unix-2.0)
  +GTK_LIBS = $(shell pkg-config --libs $(GTK) glib-2.0 gmodule-2.0 gio-unix-2.0)
  
  # If you change the versions and checksums, make sure to also update io.howl.Editor.yaml.

* `brew install gtk+3`
* `brew install pkg-config`
* `export MACOSX_DEPLOYMENT_TARGET=10.15` - 10.15 is the version found by clicking on the apple in upper left corner > "About This Mac"
* `make install`
  * if this fails, carefully read the console output, maybe you need to `brew install` something
* now you can run `./howl`

The only issue is the icons are broken, everything else seems to work!
