Build Emacs 27 with XWidget Patch on OS X

Build Emacs 27 nsxwidget Patch on OSX.md

Steps

1. Get the webkit patch for emacs 27 (0_all_webkit.patch) here: https://gist.github.com/fuxialexander/0231e994fd27be6dd87db60339238813

• https://gist.github.com/orther/8c04af954bf746d7a020be75614a527c (gist fork, old don't use)

2. Clone Emacs repo locally: git clone git@github.com:emacs-mirror/emacs.git emacs-mirror

3. Create branch for patch git checkout -b nsxwidget-patch

4. Apply Patch: git am --signoff < 0_all_webkit.patch

5. Build:

make clean
make
./configure --prefix=$HOME/work/emacs-mirror --with-xwidgets
make install

6. Locate Emacs.app and emacsclient:

ln -s /Users/brandon/work/code/emacs-mirror/nextstep/Emacs.app/Contents/MacOS/Emacs /usr/local/bin/emacs
ln -s /Users/brandon/work/code/emacs-mirror/nextstep/Emacs.app/Contents/MacOS/bin/emacsclient /usr/local/bin/emacsclient

Notes

May need to install texinfo with brew install texinfo and export the PATH and LDFLAGS that brew prints. Mine were:

export PATH=/usr/local/opt/texinfo/bin:$PATH
export LDFLAGS=-L/usr/local/opt/texinfo/lib
