compile error in rtems/confdefs header

[Vishav.Vishav at dlr.de]

Hi Sebastian,


Thanks for the reply. These are the compiler options that I use:

'-march=armv7-a',
'-mthumb',
'-mfpu=neon',
'-mfloat-abi=hard',
'-mtune=cortex-a9'

Optimization flags:
'-O2', '-ffunction-sections', '-fdata-sections',

Warning:
-Wall

-std=c99
Debug:
-g

Regards
Vishav

This is likely due to compiler options which force standard header files
to hide non-standard content. Which options do you use?

If you use

#define CONFIGURE_MAXIMUM_TASKS 1

then you can create at most one Classic API task at a time. See
