dictionarymacos
There is generally a dictionary.app on the Mac-OS.
But there isn't any dictionary development kit on the X-Code.
Now i use the X-Code (Mavericks and Yosemite).
So I downloaded the the auxiliary tools package from developer.apple.com/downloads and applied it to the /Applications/Utilites/.
And run the command "make" and "make install".
But when I reopen Dictionary.app, it couldn't do any action about of my Dictionary file.
What's the problem?
I want to make my own dictionary now.
You can install the command line tools within XCode.
Open XCode and navigate to the preferences.
From here you have to go to the Downloads-Section. Here you can see the ability to install the command line tools:
EDIT: I can see the right command line tools on the download-page from Apple:
Xcode no longer comes with Dictionary Development Kit, but you don't even need Xcode to use it.
/Applications/Utilities/DictionaryDevelopmentKit/ (without the spaces), and copy the project_templates folder to ~/Desktop/~/Desktop/project_templates/Makefile and change DICT_BUILD_TOOL_DIR from /DevTools/Utilities/Dictionary Development Kit to /Applications/Utilities/DictionaryDevelopmentKitcd ~/Desktop/project_templates/; make && make installThe dictionary should show up in Dictionary.app after you quit and reopen it. After that, try editing MyDictionary.xml or MyDictionary.css. The dictionary name is the same as CFBundleName in the Info.plist, and the bundle name is DICT_NAME in the Makefile.
If the lookup popovers show results from an older version of the dictionary, try logging out and back in. Terminating com.apple.lookupd or removing ~/Library/Caches/com.apple.Dictionary* didn't seem to work.

If you successfully made a dictionary you should put the file in
/Library/Dictionaries.In Sierra you have to make that folder yourself, as Apple has moved its own dictionaries to another location and no longer has this one. It should still work, however.
