The liblept Visual Studio 2008 Solution

The Visual Studio 2008 Solution Explorer shows these three main sections for the liblept solution:

1. liblept168 is the main project for building the library.

2. The prog_projects Solution Folder contains a sample project for building a prog program. As explained later you can use this project as the basis for building projects for the other programs in the prog directory.

3. The prog_files Solution Folder contains entries for all the .c files in the leptonica-1.68\prog folder further broken down by filename, type, and category. These are not Visual C/C++ projects. You can’t use this Solution Folder to build the prog programs. It just gives you an easy way to look at the files.

Note

The free Express editions of Visual Studio do not support Solution Folders. They will be displayed as (unavailable).

Visual Studio 2008 Tab settings

The liblept source files assume that tabs are 8 spaces, indents are 4 spaces wide, and that indentation uses just spaces. To set this in Visual Studio 2008 choose Tools ‣ Options | Text Editor | C/C++ | Tabs and set as follows:

Tab Size: 8

Indent Size: 4

(*) Insert Spaces

( ) Keep Tabs
