Re : RTEMS 4.10 Autoconf tools

[Yann Sionneau]

Hi, 

I had the same errors, it turned out to be because I compiled gcc with an outdated version of newlib.

A simple fix that worked for me was to compile gcc with the latest newlib source code.
 
I followed this tutorial on rtems wiki page : http://www.rtems.com/wiki/index.php/Building_the_RTEMS_toolset_on_Ubuntu

Hope this will help you !

My 2 cents

Yann.

OK, it turns out the built myself autotools were not the problem, I 
still have a compile fail at cpulit/posix/src/pthread.c

Error below:

This "struct sched_param" is defined in the compiler rtems includes from:

/opt/rtems-4.10/arm-rtems4.10/include/sys/sched.h as:

> /* Scheduling Parameters, P1003.1b-1993, p. 249

And it does not have the extra parameters defined.

It looks like the prebuilt mingw tools are out of sync with the 4.10 source.

We can built this bsp using Ubuntu where the tools were built in house 
using all the RTEMS patches.
