回答1:

Whosever having problem building ldid, he can get prebuild ldid from here http://joedj.net/ldid

Just download and place it in Theos/bin folder

回答2:

First download Apple's "Command Line Tools" for Xcode if you haven't already.

/usr/bin/xcode-select --install

Change into the appropriate ldid directory.

cd $THEOS/bin/

Download this already compiled version of Theos.

sudo wget http://ac3xx.com/ldid && sudo chmod +x $THEOS/bin/ldid

Apparently it seems to be an issue with Xcode 5.

Information from http://iphonedevwiki.net/index.php/Updating_extensions_for_iOS_7#Theos_and_ldid_errors .

Hope this helps.

I am assuming you are using OSX Mavericks and have the latest XCode installed. If yes, then this issue is occurring because the OSX upgrade Apple wipes out many of the core Posix libraries that were earlier present. Not sure why. Previously you could rectify this by installing "Command Line Tools" from Xcode. Unfortunately with the latest release of xcode there is no option to install command line tools from Xcode UI directly. You have to use a little hidden utility called xcode-select

Type the following command in terminal as an administrator to get things working again:

/usr/bin/xcode-select --install

Hope this helps.
