Project settings - "C" compiling

For ultimate performances, the compiler can produce machine code by using a "C" compiler. In that case the p-code is post-compiled to "C" and then compiled using a 3rd party "C" compiler. This box enables you to select the required "C" compiler and setup relevant options.


  • The possibility to use a "C" compiler depends on the T5 runtime implementation. Refer to your OEM instructions for knowing if this feature is enabled and which "C" compiler can be used.

Selecting the "C" compiler

The main list propose possible "C" compilers and indicates for which runtime system. Select the "None" choice if you do not want to enable "C" compiling.


You can ask the workbench to generate both machine code and classical p-code. If this option is selected, then the application will require more space in the runtime system. Some debugging features such as step by step debugging and variable locking are not available when the runtime runs machine code. If this option is set, you will be available during debug to change "on the fly" from machine code execution to p-code interpretation. Turning the runtime to p-code execution will then enable advanced debugging features.

If can slect the "Load compiled code" option, then the code file (typically a DLL) will be automatically downloaded together with the application code.

The "C" compiler is run in a DOS-like prompt window. You can check the "Show compiler window" option if you want this window to be visible when post-compiling.

3rd party tool folder

You must specify where the 3rd party "C" compiler is installed on your computer. You can press the "Check" button to verify that the workbench actually recognizes the compiler in this folder.

Target code file name

Here you can enter the name of the code file to be produced by the "C" compiler. Refer to your OEM instructions if your runtime system does not use the default name.
