Using TaskCPP.h, Getting ErrorPosted by groger57 on June 23, 2016 Hello: I have written an application previously in ansi C that is using FreeRTOS and works 100%. Now, I have converted the code to C++ and ready to try using the C++ wrappers and add in the calls to FreeRTOS. At this point it's tasks and queues. I'm using IAR EWARM 7.5. Just including the TaskCPP file has caused a silicon slip in the compiler. The 2 errors I am getting are : Error[Pe265]: member "Task::handle" (declared at line 169) is inaccessible C:UsersgrrDocumentsIAR Embedded WorkbenchFreeRTOSV8.2.0FreeRTOSSourceincludeTaskCPP.h 223 and Error[Pe245]: a nonstatic member reference must be relative to a specific object C:UsersgrrDocumentsIAR Embedded WorkbenchFreeRTOSV8.2.0FreeRTOSSourceincludeTaskCPP.h 223 As you can see, both are at the same line. What is causing this error, and better yet, are there any basic examples to be found on using these wrappers? Thank you, Gary Using TaskCPP.h, Getting ErrorPosted by rtel on June 23, 2016 Where did you get the wrapper files from? Using TaskCPP.h, Getting ErrorPosted by groger57 on June 23, 2016 Here: https://github.com/richard-damon/FreeRTOScpp Is it bad? Using TaskCPP.h, Getting ErrorPosted by rtel on June 23, 2016
No - not at all - quite the opposite - I've not used it myself but heard good things about it. It's just that there are a few wrappers around and I was wondering which you were using to see if it was something that can be supported on this forum. Richard Damon is a regular poster here so hopefully he will see your question and be able to provide some advise. Using TaskCPP.h, Getting ErrorPosted by groger57 on June 23, 2016 Ok, thanks. For some reason, I was under the impression that Richard Damon worked (or contributed time to) for FreeRTOS. Yes, I hope he, or someone that may have used them before can provide some insight. Maybe it would have been better to keep ansi-C and FreeRTOS in it's "home state", and lib the C++ stuff. Using TaskCPP.h, Getting ErrorPosted by richard_damon on June 24, 2016 That's my wrapper, I don't "work" for FreeRTOS but been around a while helping where I can. I will need to look at that error on my machine with the code. Sounds a bit like an error that I remember working on, maybe I got a commit at the wrong time or missed a commit. Looking at the code on GitHub, a quick fix would be to convert the private on line 168 to protected (and best to add a private again after line 169. Using TaskCPP.h, Getting ErrorPosted by richard_damon on June 25, 2016 I've committed a small patch which looks to fix these issues. I have a bigger update in the work, but haven't tested it enough. Using TaskCPP.h, Getting ErrorPosted by groger57 on June 29, 2016 Ok, thanks for the information and update.
