oofatfs problem with macro concat ##
Posted: Wed Jan 13, 2021 11:19 am
Hey there,
I am rebasing my port on the newest version of the upstream project and I am getting this error for lib/oofatfs/ffunicode.c and ff.c (after adjusting to the unicode.c rename):
It seem the preprocessor cannot process the tokens
properly.
If I replace them like this it compiles:
I am using arm-none-eabi-gcc in gnu99 mode.
Do I need special compiler flags to make this work?
I am using these:
My project was built on 1.9.4 and I didn't regularly update or anything.
Thanks in advance!
