How did you obtain the code? Git clone of the release tag, zip file from the FreeRTOS.org site, or another method?

I just tried the zip file download from freertos.org and the code generated warnings, which it shouldn’t, but not any errors. Compiler output attached as a .c file so I can upload to the forum.

Hi @soumyaims,

FreeRTOS mainline has issues with it’s two Win32 projects because of a PR to update the trace recorder. I have this PR up that fixes the MSVC demo - its currently in a good state Fix and improve WIN32-MSVC demo in FreeRTOS/Demo. by jasonpcarroll · Pull Request #891 · FreeRTOS/FreeRTOS · GitHub and should get merged in today.

I am starting on fixing this project on mainline as well today - you can expect a PR for it sometime today and I would hope it would be merged tomorrow or day after. Will update you here.

Best,

Jason Carroll

Hi Jason,

I downloaded the Pull Request #897 and I am getting the following error:

.\main.c:349:26: error: ‘TRC_START’ undeclared (first use in this function)
…\main.c:368:12: error: ‘RecorderDataPtr’ undeclared (first use in this function)
…\main.c:368:37: error: ‘RecorderDataType’ undeclared (first use in this function)
…\main.c:559:35: error: ‘TRC_START’ undeclared (first use in this function)

Simply I imported the project through project file and linked with include and lib of freertos and I am getting this error.

Hi Jason,
After including one header file path, It started showing some other issues as

E:\New_Project\latest_freertos\patch3\FreeRTOS-fa5f7c70b006aa928adb78031edb3ef1049b2f86\FreeRTOS-Plus\Source\FreeRTOS-Plus-Trace\Include/trcRecorder.h:133:27: fatal error: trcStreamPort.h: No such file or directory

This header file in not there in the entire project.

Where is this header file included? Are you trying to build a project from this fork? Can you share the exact instructions/commands that you used to clone and build the code?

The PR is now merged into main so you can pull mainline FreeRTOS/FreeRTOS then follow the below steps.

Steps I follow are this
I am using Eclipse IDE 2022-09 btw.

Open Eclipse
File->Import->General->Existing Projects into Workspace
Set Root directory to the FreeRTOS/Demo/WIN32_MingW folder
Select the RTOSDemo project
Click finish

The RTOSDemo project is now in the Project Explorer.

I then click the RTOSDemo project then hit the build button at the top and it builds fine for me as well as several other people I’ve had try it.

11

I have also added a Makefile if you have make to the directory. It will also build the demo with just the command make in the directory.
