Problem building RTEMS4.10

Tue Mar 8 06:47:25 UTC 2011

Hi,

As a work around, we commented below code in "bspstart.c" available at below location and the "make all" was successful.

\rtems-4.10.0\c\src\lib\libbsp\m68k\genmcf548x\startup

/* Switch on FPU in CACR shadow register if necessary */
  if ((Configuration_POSIX_API.number_of_initialization_threads > 0) ||
      ((Configuration_RTEMS_API.number_of_initialization_tasks > 0) &&
       (Configuration_RTEMS_API.User_initialization_tasks_table
        ->attribute_set & RTEMS_FLOATING_POINT) != 0)
      ) {
    _CPU_cacr_shadow &= ~MCF548X_CACR_DF;
  }

Thanks & Regards,

You will find a simple hello world and a simple Makefile. Not a
tutorial but enough to understand all you need.
But before to launch executables, you have to determine on which kind
of target you want to run, etc. Compilers and BSP are target
specifics.

With this:
# CPP command to write file to standard output
CPP=$(CC) -E -w -Wp,-$$

I'm having problems in a configure script:

configure:4305: powerpc-rtems4.11-gcc -E -w -Wp,-$  conftest.c
cc1: error: unrecognized command line option "-$"

Anyone know what's up?

There are (were) five reasons the timer calibation could fail on pc386. It did appear to happen in qemu and not on real hardware and in qemu inside a vm more than just qemu. It is something to do with the simulated timer jumping.  I doubt changing the amount of memory helps. It is rather random. Run again and it may not happen.

FWIW I committed a fix to the head where if it hits this situation, it will retry five times before locking up. Should help. Maybe I should apply this to the release branches.

This is a bug in the BSP.  We will have to investigate this further.

gcc-target-default.cfg is junk. Don't use it.

It's included by leaf.cfg which is included in the demos, unless I'm very confused.

In a network-demo Makefile:
include $(RTEMS_MAKEFILE_PATH)/Makefile.inc
include $(RTEMS_CUSTOM)
include $(PROJECT_ROOT)/make/leaf.cfg

In leaf.cfg:
# Pull in the desired "target" compiler
# Programs built on the host use automake generated rules.
# This will not change $(ARCH) -- binaries will still be place as per target
include ${CONFIG.CC}

Adding an echo to the network-demo Makefile:
[dufault at finny12 rtems_main]$ make echo_config_cc
CONFIG.CC=/opt/rtems-4.11/make/compilers/gcc-target-default.cfg
[dufault at finny12 rtems_main]$

If you configure without the --disable-posix,
it will get around this.

Also you can use --enable-rtemsbsp=XXX to configure
a specific BSP
