Build error 71 on Xcode

I've been working on a GUI program for a while now, and I just can't get it to compile correctly, I am constantly receiving the following error -

Command /Developer/Library/Xcode/Plug-ins/CoreBuildTasks.xcplugin/Contents/Resources/copystrings failed with exit code 71

I've done some searching around to try to find a solution, and found a question on StackOverflow with the same problem over at - copyplist failed with exit code 71 - however I've tried following the steps provided as the best answer, to no avail, and I've had no luck tryi开发者_开发知识库ng anything else.

I do think, however, that this is a problem with my Ruby install, because I did some installing only a short time back.

I've tired re-installing Xcode, deleting the Developer folder and getting Xcode to rebuild, and a number of terminal tricks to try to fix the problem. At the moment I'm unable to compile.

Everytime I had copystrings failing it was due to a syntax error. Make sure every string starts with quotation marks and ends with quotation marks, make sure every string assignment has a semicolon at the end.

"foo" = "bar";

Also watch out for quotation mark escaping:

"foo" = "bar with \"escaped\" quotation marks";

For me, it was missing semicolons most of the time.
