Got a project that compiles on another computer (which I now cannot access to test whether it's still so), but now that I'm an another machine, same version of CubeIDE (1.12.1), I get the error quoted above. I'm not sure when I updated last & whether I tried to build then.
Why would the compiler not find a type within library stuff? I haven't touched those files.
Well, if, in sysmem.c, I add
#include <sys/types.h>
it compiles. I don't like messing with the vendor library files, though ;)
EDIT:
This was with toolchain GNU Tools for STM32 (11.3.rel1).
When I chose Fixed: 10.3, it compiles as before.
Why did I try that? Because, in a related project, I was suddenly also getting BS errors that prevented the build, e.g. about casting from a pointer type to a uint32 in a constexpr - this compiles just fine with 10.3, and it's essential, using unsigned values from a linker script, to address certain memory regions in the program.
Note to self: never let IDE select toolchain willy nilly, and not waste time with BS.
(I didn't even know it did that by default)
