sys_stdio_mphal.c compile failure?

Greetings. The last few days, I've had a problem compiling; the problem seems to be with recent changes to sys_stdio_mphal - in particular as related to the #if MICROPY_PY_SYS_STDIO_BUFFER

I'm building on Ubuntu with all the latest code, tool and library updates as described here:


Does anyone else have this problem? Should I open a GitHub issue? (sorry I didn't take time to propose fix)


Code: Select all

Did you rebuild instead of just build? Missing qstr errors are more often than not due to and related issues

hmm... interesting.

well, indeed if I comment out the MICROPY_PY_SYS_STDIO_BUFFER in mpconfigport.h it successfully builds.

and if I put it back and do another make (no make clean) - the error returns.

I'm fairly certain I've fetched fresh code since the April date of the GitHub issue, without seeing this problem.

Thanks for the info; I'll add a comment & not create a new issue.
