4diac FORTE FAQ
4diac IDE Answers
When I open a certain perspective, a view element is missing, how can I get it back?
There are two possibilities to do that:
-
Reset Perspective: When right-clicking on the active perspective’s name in the perspective switcher, you get a context menu with the option Reset. By selecting this item, the perspective is reset to the initial configuration showing all views again and at their original place.
-
Show View Menu: The menu item brings up a selection dialog that allows you to open any view. By searching through the items you can reopen an accidentally closed view. This option is especially of interest when you have a custom perspective layout you don’t like to lose by resetting the perspective.

When I download my application, I get an UNSUPPORTED TYPE error message in the Deployment Console
This message appears for multiple problems: * Make sure that you have the source code (*.cpp, *.h) of all Function Blocks within your Application. Also check if all source files are listed within a CMakeLists.txt file. * Ensure that the missing Function Block is included in your built version of 4diac FORTE. In 4diac IDE the path to your correct forte.exe has to be defined. Or start your forte.exe directly (development tool specific)
When I download my application, I get a STATUS ACCESS VIOLATION error messages in the Deployment Console
Check if you used Composite Function Blocks within your Application. Make sure that you have the source code (*.cpp, *.h) of all Function Blocks within the Composite’s Network. Also check if all source files are listed within a CMakeLists.txt file.
When I download my application, I get a Create FB Instance failed error
Verify that the interface of the Function Block you want to download is the same as those available on your 4diac FORTE executable. In case you download a Composite Function Block, please make sure that its Function Block Network matches the Function Block Network within your 4diac FORTE executable. When in doubt, export your Function Block and compile 4diac FORTE before you download again.
When I want to download my application, I get a connection refused# message
Examine the following topics: * Make sure that the port numbers used in the Runtime Launcher of the Deployment view are the same as those used for the .element4diac]MGR_ID of the Devices in the System Configuration. * Check if 4diac FORTE runs on a different port * Check in Task Manager (Windows) if an "old" crashed 4diac FORTE blocks the port * Check if Monitoring has been started before downloading (FORTE only supports a single connection at the management interface)
How do I use ARRAYs?
When you create a new Function Block, choose the desired type for your array elements in the drop down of the specific data and set the desired array size . For initializing, put the values in curly brackets (e.g., \{1,2,3}).

Windows/Cygwin: The setup script runs to completion but when building the target, I get strange compile errors
-
First, check for any strange output of the setup script. Maybe your system misses something.
-
Do you have spaces in the path to your 4diac FORTE? Some Cygwin versions have problems with these.
CMake/Cygwin: Can not find C and C++ compilers
CMake Errors:
In this case, you need to tick the check box Advanced and look for CMAKE_CXXX_COMPILER and CMAKE_C_COMPILER and set the path and executable for your C and C compiler. As an example, for Cygwin this could be [.fileLocation]#c:\cygwin\bin\g-3.exe# for the C++ compiler and c:\cygwin\bin\gcc-3.exe for the C compiler.
CMake/Cygwin: Can not find RC Compilers
CMake Error:
your RC compiler: CMAKE_RC_COMPILER-NOTFOUND was not found. Please set
CMAKE_RC_COMPILER to a valid compiler path or name.
Again you need to tick the check box Advanced and look for CMAKE_RC_COMPILER. For Cygwin or MinGW on Windows, it needs a file called windres.exe (e.g., C:\cygwin\bin\windres.exe).
FORTE is C, why are you then using the C-style include files for the standard c library instead of the C style include files?
The main reason for this is that not all platforms provide the correct C include files. This especially applies to real-time OS such as eCos where you can freely configure the supported features. Using C style C include files on these platforms would pull lots of stuff from the compilers in and result in a bigger image or even worse it would not compile. So as to current experience, C style include files are more reliable.
Within my 4diac FORTE console, I get UDP-Socket Send failed: Network is unreachable
Consider to explicitly set up multicast IP routing in the kernel with the route command. This has been an issue on Raspberry Pi, where executing the following command resolved the problem:
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
The IPs are the desired multicast IPs.
