Hello,
I tried to port an TouchGFX-Application from ARM5-Compiler (ARMCC) to ARM6 (ARMCLANG). Both compilers are from KEIL (µVision).
Well it does compile, but it doesn't link:
Warning: L6869W: abstractpainter.o requested the Rogue Wave Standard C++ Library which has been removed from the product. This might cause link errors because libc++ is used instead.
Error: L6242E: Cannot link object abstractshape.o as its attributes are incompatible with the image attributes.
(There are a lot more linker errors)
I do believe the provided TouchGFX-Library is not compatible with ARMCLANG (and there is no other library supplied in ...\TouchGFX\4.10.0\touchgfx\lib\core\cortex_m7\Keil)
Is that the case, or did I miss something else?
Solved! Go to Solution.

Great. This patched version seems to work.
I will do some tests, but it does look good.
I presume you are going to test this library as well? Will there be an official release after successful testing?
Thanks again for your efforts!!!

The library will be a part of the next official release, yes. Nothing i can do right now other than offer it as an add-on and we'll do more rigorous testing when we get closer to release.
I'd be happy to hear back from you about performance. I'm only expecting it to improve, though :)

Hi Martin,
I would like to refresh this topic and ask you if there are any plans regarding library for ARMCLANG?
I have been developing an app with touchGFX, but I prefer rather STM32CubeIDE than Keil as an developement enviroment. Everything worked fine for a long time of testing and evaluating. But when I moved to the Keil (because I have to use certified compiler in production) I hit this problem. I can't and I don't want to use ARM5 compiler, because I use C++14, therefore the best option is to use ARM6.
The library you compiled with arm6 works nice, but I am wondering if there will be any support for the future releases? I would like to be updated with all touchGFX features ( you do a great job), without an updated lib it can be harmful. I will have to ask you to compile it again one day :squinting_face_with_tongue:
@Edit.
Okay, I didn't notice the small button "More answers" at the bottom so I didn't read all posts. Now I can see that you plan to add this into the next version. I worked to much today that I missed it...

There will most definitely be support in the next release :) And yeah, this forum software isn't the best at getting an overview, haha.

HI @Martin KJELDSEN ,
I have come to the same conclusion as @PBull. Sadly, it seems that this issue has not been completely resolved in the release 4.14 of TouchGFX.
If I try adding any Keil middleware to my project (which I need to), the "Short enums/wchar" (-fshort-enums -fshort-wchar) option has to be enabled.
Would it be possible to have a patch of the library with the short enum/wchar enabled? That would be very usefull.
Best regards,
Maxime

Hi,
Martin was so kind to upload a "fixed" version for TouchGfx 4.14
Maybe we will see "native" support in TouchGfx 4.15? @Martin KJELDSEN
