This section explains the steps to compile and run the FairCom DB API C tutorials from the Microsoft Visual Studio Developer Command Prompt window (also called the Native Tools Command Prompt window).
This section is oriented toward a command-line running on Microsoft Windows. The principles are similar for other environments that provide .NET support, such as Linux/Unix.
Where 2017 is your version of Visual Studio and X64 is for a 64-bit version of c-tree (note “64” in the name of the default installation directory) or X86 for a 32-bit version of c-tree.
Warning - the Developer Command Prompt Start menu entries which do not specify a bit depth, it will open the 32-bit version of the Developer Command Prompt.
For more details, see the Microsoft Developer Command Prompt web page.
This batch file will determine the version of the Microsoft C compiler you are using and will set the internal paths accordingly. It will then compile the tutorials included for this driver.
After the tutorials have been built, the batch file will run them one-at-a-time. A prompt will ask you to press <Enter> before running each tutorial.
If you see a c-tree error, you can look it up in the Error Code Reference. See the "Troubleshooting" section below for solutions to common problems.
The first tutorial should look similar to the image below when running:
INIT
Logon to server...
DEFINE
Open table...
Add fields...
Create table...
MANAGE
Delete records...
Add records...
Display records...

DONE
Close table...
Logout...
Press <ENTER> key to exit . . .
Executing the Tutorials by Hand
You can run the tutorials individually using the executables located in sdk\<your-API-folder>\tutorials\cmdline. sdk\<your-API-folder>\tutorials\cmdline.
ctdb_tutorial1.exe
ctdb_tutorial2.exe
ctdb_tutorial3.exe
ctdb_tutorial4.exe
Running in Debug Mode
To fully observe this API in action, you can single-step through the code with the Visual Studio integrated debugger. You can call this as follows:
devenv ctdb_tutorial1.exe
devenv ctdb_tutorial2.exe
devenv ctdb_tutorial3.exe
devenv ctdb_tutorial4.exe
Hint: A better way to single-step and debug is to open the Visual Studio solution that we provide. See Compile Using Microsoft Visual Studio IDE.
Troubleshooting
This section lists some of the errors that can occur when compiling and running these tutorials:
cl.exe not found! Please set environment for Visual C/C++ compiler.
The most common cause of this error is running the BuildTutorials.bat file from a DOS shell or normal Windows command shell rather than from the Visual Studio Developer Command Prompt window.
ERROR: [133] - Initialize(): ctdbLogon()
The most common cause of this error is that the FairCom Database Engine is not running on your machine. Remember that the c-tree evaluation license times out after 3 hours, so the server might have exited and needs to be restarted. See Starting the FairCom Database Engine.
