Hugin Compiling OSX

Introduction

OSX Users: This tutorial describes how to build hugin on OSX via MacPorts. Fink users should also be able to use it even though the commands and directory structure is different from MacPorts.

• Directory structure where everything is built and installed:
  • MacPorts: /opt/local
  • Fink: /sw
• Main commands to install/update/uninstall/deactivate packages:
  • MacPorts: sudo port [install][update][uninstall][search] <package1> <package2> <packagex>
  • Fink: sudo apt-get [install][update][uninstall][search] <package1> <package2> <packagex>

Note: These are only the bare command options for both port and apt-get. See their respective websites Macports.org and Finkproject.org for documentation.

Building environment

Download and install XCode

Download and install the XCode Tools version for your MacOSX version: Xcode 2.4.x for MacOSX 10.4.x or below and Xcode 3.x for 10.5.x (Leopard). You will not use the Xcode development environment itself, but the MacOSX system comes without the GNU compiler, builder, linker and so on. For those who are brave enough to ponder into the dark corners of the installed base: You will find a 4.x version and a 3.3 version of the GNU compiler and it's "companions". Do not remove either of them. The 4.x version is used for i386/X_64 builds and the 3.3 version is used for the "older"PPC builds.

Install CMake

Get and install the build system CMake, version 2.4.7 or later, from CMake.

Install Macports

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

Fink commander

Note: This tutorial describes how to build Hugin with MacPorts. This should more or less be the same for Fink. All references to /opt/local that are mentioned here for MacPorts shoudl be changed with /sw for Fink. 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?

Subversion (SVN)

Get and install Subversion

Install necessary libraries

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.

Build libpano13

Download and build libpano13 from SourceForge. Alternatively, use SVN to checkout a fresh copy of libpano13 (Instructions).

Build SVN libpano13

To build and install the svn version (preferred) you first need to edit the bootstrap file and change LIBTOOLIZE=${LIBTOOLIZE:-libtoolize} to LIBTOOLIZE=${LIBTOOLIZE:-glibtoolize}.

$ ./bootstrap --with-jpeg=/opt/local/ --with-tiff=/opt/local/ --with-png=/opt/local/
$ ./configure
$ make
$ sudo make install

By default it will go into /usr/local/lib).

WxWidgets on Tiger (10.4.x)

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

Fix lib_boost

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 -

Get and compile hugin

Get Hugin from SVN

Check out the hugin sources from SVN, like:

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

====Create hugin_build directory==== 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

Configure build

Configure hugin using cmake from inside the build directory:

$ cmake ../hugin

Compile Hugin

Compile Hugin and friends:

$ make
$ sudo make install

Watch the pretty colors go by. Give the dog another quick spin around the block; you're finished. Look for the new bundle Hugin.app in usr/local/Applications/ or in usr/local/bin/. Copy or link 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
