Hi,
Thank you @yangx30 for the hint, but… well, I know about this commit, it has been integrated in the master branch since more than a year. I checked the branch and didn’t found a “rollback” at least in the commit messages. So it is supposed to work out of box, even in the 2.9.1 release.
I tried the latest commit of that repository, it still doesn’t work. So there is probably a regression somewhere.
@yangx30 Actually, you opened this issue and closed it right after. But in my case I still have the same compilation errors as you had.
So, for now, I’m stuck with mbed, but I have some succes with the other … OS/solution/whatever?
