High Sierra issues with symlinking Toolchain directory #96

Closed andrewhavens closed 5 years ago

andrewhavens commented 6 years ago

You might run into this issue when running Mac 10.13 (High Sierra), Xcode (installed via the Mac App Store), and RubyMotion 5.7:

RubyMotion attempted to create a symlink under /Applications/Xcode.app/Contents/Developer/Toolchains, but wasn't able to.
Please run the following command manually: 
ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.13.xctoolchain
You may need to run the command above with `sudo`.

Mixed into this long block of text is a helpful message:

Please run the following command manually: 
ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.13.xctoolchain
You may need to run the command above with `sudo`.

(It would be nice if this message was formatted like the other kinds of RubyMotion error messages so that it would be easier to read).

However, this issue can also cause another issue to happen. The error output could be written to a .bridgesupport file. In my case, my sqlite3.bridgesupport file was generated incorrectly. The workaround solution was to remove the file so that it could be regenerated:

Pretty sure this has been resolved, so I'm going to close this issue.
