An external build script I have for creating an embedded framework relies on libtool, which was in /Applications/Xcode 6.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin
To get the framework to build properly, I had to copy libtool into manually /Applications/Xcode 7.app/Contents/Developer/Platforms/iPhoneOS.platform/usr
Whats the best approach to make this permanent? How about when using Travis CI? I feel like editing xcode is not ideal.
Probably too late for an answer but anyway, it might help someone else in the future. The right way to invoke libtool (or any other binary within Xcode's toolchain) would be to use xcrun to locate it:
xcrun -sdk iphoneos libtool <libtool_args>
Or you could also obtain the actual absolute path to it by calling xcrun with the flag -f and then do as you please with it:
LIBTOOL_PATH=$(xcrun -sdk iphoneos -f libtool)
