Could not find the solution to this issue but I have side stepped this by creating a global variable MAX_SIZE.

okay but will this pass the array by copying it or it will be a reference to original array only.

Post by sean-barton on Ambiguous namespace in library dependencies ^{CODESYS Forge talk (Post)}
I am trying to install the MQTT Client SL in an existing project I have been working on for years. After adding the library to the project, and without adding any other code, upon building I get a C0180: Ambiguous namespace 'MBM' error between the memory block manager (MBM) in the NetBaseSrv dependency of the MQTT Client SL library and the memory block manager (MBM) in the CAA CanL2 dependency of the 3S CANopen stack library. I have tried: * setting "Only allow qualified access to all identifiers." in the properties for both the parent libraries. * deleting the 3S CANopen stack library. Upon (re)building the error simply points to another conflicting library - there are many. * deleting the Library Manager and rebuilding it. * adding the memory block manager library (used in the NetBaseSrv) manually and changing its namespace to MBM3S. None of the above allow me to access the MQTT library through its namespace (MQTT). Adding the memory block manager manually removes the C0180 error, but the MQTT library is not accessible - i.e. mqttClient : MQTT.MQTTClient; highlights the mqttClient as "Identifier 'MQTT.MQTTClient' not defined". Is there anything else I can try?

Old thread, I know - but it still has good answers. I would like to add a bit of info to it, as I was having a problem that lead me to this thread, but didn't give an exact answer. I am porting a project to a different PLC architecture. (Wago PFC300) A GVL named 'GVL' in the POUs section of my project was shadowed by a PLC-specific library in the Application->Library Manager. So all the existing references in the device specific code to 'GVL.something' would not resolve. Right-clicking the GVL in the code and 'Go to definition' would point me to the library in the Application Library Manager. All I had to do from there, was right-click the library, and set the property 'Only allow qualified access to all identifiers' in the library.

Hello, I need a few libraries in CoDeSys 3.5. I want to download them using the "Download Missing Library" option from the Library Manager menu. However, I keep getting a "Download Failed" error. Despite trying at different times, I haven't been able to download them. What should I do?

Post by tyronnosaurus on SysLibMem.lib Where To Download? ^{CODESYS Forge talk (Post)}
It should come by default on a normal install of Codesys 2.3, but it's a bit hidden: Like for any other library, go to Resources > library Manager > Right click on list of libraries > Additional library. On the browser that opens, instead of looking in the default folder, use the dropdown menu at the bottom to change the folder (SysLibMem should be on the 3rd folder).

Hi Suyash! To avoid library mismatch errors in CODESYS, always use the same IDE version your project was created with. Use the Library Manager to check and update libraries. For consistent results, keep a record of project and library versions, and avoid auto-updates unless necessary. https://forge.codesys.com/forge/talk/Engineering/thread/ea1bdacd28/Geometry Dash

Yes, you are right. I think the help is pretty clear: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_library_development.html It helps you to find errors in the source code of your library if you want to create a library which is using pointers and you want to use your library on 32 and/or 64 bit platforms.

I have library projects which has few function blocks. I have assigned security to each FB. I want to protect them and user can only be able to use it without viewing the code inside. What kind of file I should send to user? Is it compiled library file?

Post by alexgooi on How to protect library project? ^{CODESYS Forge talk (Post)}
Hi aniket-b, If you save the library as a compiled library you are not able to see the source code. When the end user tries to view inside the object, CODESYS will give a notification that the source code is missing, see attachment. In short if you don't send the source code, it will not show.

I am trying to create a new proyect using the Raspberry Pi 4.11.0.0 package with Codesys 3.5 SP20, I am able to communicate with the Raspberry and start the runtime application but when I create a new proyect I have these errors. When opening the library manager of the proyect the library of the IoDrvGPIO is used so I dont really know whats happening.

Post by abauza on Image Pool using in other libraries ^{CODESYS Forge talk (Post)}
Hi im Albert, im developing libraries for my PLCs and i have some issues on visualization part. First of all I have done a library that have a image pool with a list of 4 gifs "ImagePoolErrors" (i've tested in other projects and it works) but the problem comes when i create another library that in the visualization part contains images from my image pool library, when i simulate a program that includes a instance of my second library object the visualization images dont show, any of them, i've checked all the references and tried some options of the image properties but without any difference. Here is the screenshots of the first library (that contains Image Pool) and the second library (that includes images of the image pool first library) and the visualization simulation (with the missing image gif issue). Any idea of what i forgotten in the process? If you need any detail of the library or of the project or you need the library file, ask me, thank on advance

Hello, I am getting the following error and warning when trying to download a project into a PLC: - Library CmpTargetVisu has not been added to the Library manager, or no valid license could be found - Unkown type: 'CmpEventMgr.EventParam' As far as I can see, both are included, and licensed, in the library manager (see image). What could the problem be, and how would I resolve this?
