Building on Linux

Prerequisites

All requisites should be available for your distribution. The most important are:

• The basic program build tools. On Ubuntu and Debian these are available in the meta-package build-essential. On other distributions, you may need to install the GNU C++ compiler separately. The package is going to have c++ or g++ in its name. If you can't find the equivalent of build-essential meta-package for your distribution, be sure to install the 'make' utility as well.
• CMake, the cross platform build system.
• Qt version 4.4.0 or higher (but Qt version 5.x won't work). If you have KDE 4.1 or later installed then you will have the runtime libraries but you may have to install the header files and utilities. These are in the package libqt4-dev on Ubuntu and Debian. Generally, developer packages have the -dev or -devel suffix.
• Several more developer packages:

These are the package names on Debian and Ubuntu, find the similar ones for your distribution. For Fedora, use '-devel' instead of '-dev' as suffix and drop the version numbers.

Configuration

Open a console window and go to the directory that contains the scantailor sources. From there, run the following (notice the dot at the end):

There will be lots of messages from cmake ending with:

• If you have missing dependencies you will get an error message telling you what is missing. You can then search for the missing package and install it.
• If you have a library and header files installed in a non-standard place then cmake will not find them. In that case you can run the interactive program ''ccmake'' which allows you to specify paths to libraries and header files.

Compilation and Installation

Building on Mac OS X

MacPorts

MacPorts has already scantailor as a package(Xcode prerequisites for MacPorts apply)

Building on Mac OS X is very similar to building on Linux but the package names are different and the MacPorts packaging system needs to be installed in order to get the needed packages. Also the nonstandard location that MacPorts installs qmake to needs to be specified.

Prerequisites

• Xcode. Install it either from your Mac OS X install media or better, go download the latest version from http://developer.apple.com/TOOLS/Xcode/
• MacPorts. Choose and install the correct dmg version for your version of Mac OS X from http://www.macports.org/install.php, then open a Terminal window and run:

• Then install the rest of the needed packages with

This installs:

• CMake, the cross platform build system.
• Qt version 4.6.0 beta currently
• Boost version 1.40.0 including libboost
• libxrender

The rest of the needed packages are installed as dependencies of these.

Configuration

Download the scantailor source code package and then upack the source by entering the following in the directory where the source package resides:

Replace the file name above with the name of the version that you have downloaded. Typing the first few letters of the name and typing tab will autocomplete the filename for you.

Then navigate to the directory that contains the scantailor sources. From there, run the following (single line and mind the dot at the end):

There will be lots of messages from cmake ending with

• If you have missing dependencies you will get an error message telling you what is missing. You can then search for the missing package and install it.
• If you have a library and header files installed in a non-standard place then cmake will not find them. In that case you can specify them as above for qmake or run the interactive program ''ccmake'' which allows you to specify paths to libraries and header files.

Install Instructions

1. Download and unzip to any directory. The unzipped directory structure is shown here:
2. The C/C++ headers are contained in include directory.
3. The static and dynamic libs are located in the libStatic and libDyn directories.
4. Universal libs may be created by running the makeUniversalLibs.sh script. (Make sure this script has execute permission first 'chmod a+x makeUniversalLibs.sh') The contents of this shell script are shown here:
5. This download is both the trial and full version.

How to Distribute a dylib with your Application

(This information is general and applies to any dylib on Mac OS X.) On Mac OS X, a dynamic library (dylib) has an 'install name'. The install name is a path baked into the dynamic library that says where to find the library at runtime. When an application is linked against a dylib, the path is saved in the app's binary so that it can find the dylib at runtime.

The install name of a dylib can be viewed by using otool. For example:

This means that unless the DYLD_LIBRARY_PATH environment variable is set to allow the runtime linker find the dylib, the dylib must be placed in the exact location as specified by the install name.

However, the install name of a dylib can be changed by using the install_name_tool utility. The @loader_path keyword can be used to make it relative to an install directory.

Chilkat recommends becoming familiar with the install_name_tool command and it's various options. For example, this command changes the install name of libchilkat.dylib to be relative to the location of the binary using it:
