Hugin Compiling OSX

Building environment

1. Download and install the XCode Tools version for the operating system on the machine that you will use for the building job.
2. You may find Fink Commander helpful. Unfortunately it seems unsupported / unmaintained. The Fink FAQ may help. Can somebody please describe here how to install Fink and Fink Commander?
3. You may find Porticus helpful with MacPorts
4. Get and install Subversion

Compiling Hugin.app on OSX

OSX Users: Do you wish you could test those snazzy new Hugin features, provide feedback on its development, or contribute patches to make it a better tool? Here are the steps necessary to compile your very own Hugin.app direct from the latest sources:

1. Get and install the build system CMake, version 2.4.7 or later, from CMake.
2. If you don't have it already, install MacPorts, which provides the port command, from MacPorts, giving you compilable package access to thousands of pieces of open source software. If you already have macports (formerly darwinports) installed, update it:

   $ sudo port selfupdate

   Make sure you have synced the latest port files:

   $ sudo port -d sync

3. Use port to install the necessary libraries and commands for Hugin:

   $ sudo port install boost tiff jpeg libpng wxWidgets subversion openexr exiv2

   Wait as all of these source packages (and it's dependencies) are downloaded and compiled, and installed into /opt/local. Go get a frappe, walk the dog, and total the first 1000 prime numbers in binary. Rinse, lather, repeat as necessary.
4. Download and build libpano13 from SourceForge. Alternatively, use SVN to checkout a fresh copy of libpano13 (Instructions). Build and install it (configure might need to be used with "$ ./configure --with-jpeg=/opt/local/ --with-tiff=/opt/local/ --with-png=/opt/local/", by default it will go into /usr/local/lib).
5. Fix a problem on Tiger (10.4.x): Tiger comes with WxWindows version 2.5. The Hugin cmake will search OS paths first and will find it's own version 2.5 instead of your freshly compiled 2.8. You need to get Tiger's 2.5 version out of the way as you won't be able to build hugin succesfully.

$ sudo mv /usr/bin/wx-config /usr/bin/wx-config-2.5
$ sudo mv /usr/include/wx-2.5 /usr/include/wx-2.5-macTiger

1. Check out the hugin sources from SVN, like:

   $ svn co https://hugin.svn.sourceforge.net/svnroot/hugin/hugin/trunk hugin

2. Create another directory alongside the newly created hugin/ for the build files (a cool feature of CMake: it doesn't need to pollute your source directory with build files!):

   $ mkdir hugin_build; cd hugin_build

3. Configure hugin using cmake from inside the build directory:

   $ cmake ../hugin

4. Fix a (hopefully temporary) issue with Macport's threaded Boost library not providing generic link names for libboost_thread:

$ cd /opt/local/lib
$ sudo ln -s libboost_thread-mt.a libboost_thread.a
$ sudo ln -s libboost_thread-mt.dylib libboost_thread.dylib
$ cd -

1. Compile hugin and friends:

   $ make

   Watch the pretty colors go by. Give the dog another quick spin around the block; you're finished. Look for the new bundle src/hugin/Hugin.app. Copy it to /Applications, or your preferred location, and commence testing.

Note: This is a new build configuration and you may encounter problems. Report them on the Hugin mailing list.

Important Note on the produced Bundle

Since the produced Hugin.app bundle links dynamically to libraries outside of the bundle, it is not yet portable, i.e. cannot be copied or shared unless the other machine has the same collection of libraries available in the same places. This is to facilitate development and testing (re-compile external libraries and test without re-building). Building a fully portable universal binary version at the command line is planned.

Notes on wxWidgets

Note: For testing purposes you might use wxWidgets 2.6.4, but the newer versions of the 0.7 version no longer fully support 2.6.

wxWidgets, the GUI toolkit currently employed by Hugin, is currently at version 2.8.4. You can use either this version or try the older version 2.6.4. Switching to the older version 2.6.4 is easy:

$ sudo port deactivate wxWidgets; sudo port install wxWidgets26

and recompile by typing cmake ../hugin; make in your build directory. Switching back is as easy as:

$ sudo port deactivate wxWidgets26; sudo port activate wxWidgets
