Getting Started with the LEADTOOLS Linux Libraries and Demo Projects

1.

Install the Java Development Kit (JDK) 1.6 which includes the Java Runtimes (JRE) and libraries. Obtain them from http://www.oracle.com/technetwork/java/javase/downloads/index.html

2.

Using Terminal, install the following required Linux libraries. Use command lines as shown in the following table:

Package

Command

uuid-devel

sudo yum install uuid-devel

gcc

sudo yum install gcc kernel-devel

sudo yum install gcc

sudo yum install gcc-c++

glibc-devel

sudo yum install glibc-devel

kernel

sudo yum install gcc kernel-devel

sudo yum install kernel-devel

sudo yum install kernel-headers.x86_64

libX11

sudo yum install libX11.i686

sudo yum install libX11-devel

xorg-x11-fonts

sudo yum install xorg-x11-fonts*

3.

Create symbolic links for each required library (libX11.so, libstdc++, libuuid.so). The original libraries for these files are in either "/usr/lib" or "/usr/lib64" For example, if you are working on a 64 machine, from within Terminal run the following commands:

A file called "libX11.so.6.3.0" would need a link named "libX11.so" for that file. To  create the link, from within Terminal run the following commands:

Do the same for the remaining required libraries.

4.

Install Eclipse from http://www.eclipse.org/downloads/?osType=linux

5.

Create symbolic links for the LEADTOOLS libraries. The libraries are at /home/user/LEADTOOLS 19/Bin/Linux/x64 (the 64-bit libraries) and /home/user/LEADTOOLS 19/Bin/Linux/x32 (the 32-bit libraries).

Create symbolic links for all libraries.

For example, to create a symbolic link for libltkrn on a 64-bit machine, from within Terminal, run the following commands:

Do the same for the remaining required libraries.

1.

Go to the location where you extracted Eclipse and run it.

2.

From within Eclipse, choose File -> Import. When the Import dialog appears,  select General ->  Existing Project into Workspace.  Click Next.

3.

When the Import Projects dialog appears, select the Select Root Directory radio button. Click the corresponding Browse button.

Navigate to the location where you installed LEADTOOLS and browse for the demo you want to use. Click OK and then Finish to start importing the demo.

4.

From within Eclipse, open the Project Explorer.

5.

Select the project you imported. Right-click the mouse and choose Properties. Go to the C/C++ General section and select the Paths and Symbols selection.

On the Includes tab, click Add. In the Directory dialog, add "/usr/include" and click OK.

On the Library Paths tab, click Add. In the Directory dialog, add ""/usr/lib64" for Linux 64-bit and "/usr/lib" for Linux 32-bit and click OK.

6.

From within Eclipse, open the Project Explorer again. Select the project and expand it. Select a "C" file. Right-click it with the mouse, and choose Properties. Go to the C/C++ General section and select the Paths and Symbols selection. On the Includes tab, click Add. In the Directory dialog, add "/usr/include" and click OK.

Do this for each of the remaining "C" files

7.

Build the project and run it.

8.

Because the demo is a console application, pass the parameters into the Arguments tab of the Run Configuration dialog.
