[sword-devel] Can't build on OS X (undefined reference to UnicodeString)

Sorry for taking a while to reply!

I bumped into this issue with iOS a few months ago and then ran out of time to fix it. “Recently” (months ago?) Chris added some more dependencies on ICU into SWORD and iOS chokes on that. When I look for:
<unicode/ucnv.h>
it can’t find it. The available headers under iOS are:

~ 🍉  ls /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/usr/include/unicode 
localpointer.h putil.h        umachine.h     utext.h        utf_old.h
parseerr.h     uchar.h        uregex.h       utf.h          utypes.h
platform.h     uconfig.h      urename.h      utf16.h        uvernum.h
ptypes.h       uiter.h        ustring.h      utf8.h         uversion.h

(This is for iOS 7.1, which was the current version at that point, and the version of ICU included is reported as "51.1")
If I have time, I’m going to #ifdef out the stuff Chris added that breaks the build under iOS so that I can continue to use the built-in ICU rather than having to roll my own for iOS. But due to a lack of time right now, PS is sitting there needing about 1 hour of work, plus a fix for the above error, before the next version is released. However, me #def-ing out new code that Chris added is a band-aid fix, as he’ll probably add more funky features that I then won’t be able to use :( Then again, perhaps I’ll have handed PS over to someone new by then & that can be their problem to fix? :) :)

I don’t have the OS X components required to check how similar this is for OS X (installed on this machine, that is), but this is the current situation with iOS. Perhaps that helps you, perhaps not? :) :) :)

Thanks, ybic

Since Qt already comes with the functionality built in, BibleTime distributes its OS X binary without the extra size of ICU.

Not sure what the story is now). If you have the headers and the link library, you'll need to specify the proper search path. For ICU, you can add the standard search directories to your CMake invocation using the standard mechanism for appending library and header search paths. For CLucene you can use that method, or specify CLUCENE_HOME in your environment variables before invocation.

The relevant files are cmake/Find{ICU,CLucene}.cmake in the Sword source tree.

I believe, however, that BibleTime builds without them as Qt is used in place of ICU and CLucene is linked directly into BibleTime for its custom search functionality. Obviously, feel free to edit your local .sh script. Those are only given there for examples of how to build with CMake for people who are not familiar with the system much as usrinst.sh is more of a guideline. For instance, I doubt you're looking to build the Python or Perl extensions.
