Re: Compilation error EPICS for RTEMS

[Bruno Seiva Martins <brunoseivam@gmail.com>]

Hi Eric,

Only now I was able to get back at working with RTEMS/EPICS. I tried your recipe. I used the exact versions you mentioned and your updated script. Everything compiled, except for EPICS base (step 8). I skipped step 7 because I'll only use the pc386 BSP. I am compiling on a Ubuntu 12.04 64 bits machine.

The compilation process fails with:

Where "Saindo do diretório" means "Leaving directory"

I don't believe the problem lies within the toolchain, because the example ticker.exe runs fine.

I have no clue where the problem might be...

Why doesn't libbspExt compile? I don't see any output.

I have never understood why you all didn't work to
get the libbspExt capabilities into the PIC interrupt
model code. In particular, the new shared implementation
by Sebastian Huber. 

FWIW I am not even sure at this point what capabilities
it offers that you don't have in the shared implementation
of the PIC interrupt model.

AFAIK the RTEMS-4.11 stuff is still a development branch.

I just checked and found that I could use EPICS/RTEMS-4.10 on my OS X "Mountain Lion" host as follows:

1) Download and install gmp-5.0.5, mpc-1.0., mpfr-3.1.1, automake-1.11.1and autoconf-2.68 with PREFX=/usr/llocal/rtems/rtems-4.10.

2) Run the getAndBuildTools-4.10.sh script (attached).

3) Downloaded and unpacked rtems-4.10.2.tar.bz2 and rtems-addon-packages-4.10.2.tar.bz2 from http://www.rtems.org/ftp/pub/rtems/4.10.2/

4) Ran the bootstrap script in the top RTEMS source directory.

5) Build RTEMS:

/usr/local/rtems/rtems-4.10/src/rtems-4.10.2/configure --prefix=/usr/local/rtems/rtems-4.10 --enable-cxx --disable-rdbg --enable-tests=samples --enable-networking --enable-posix --target=powerpc-rtems4.10 '--enable-rtemsbsp=mvme3100 mvme2100 beatnik'

make -w

make -w install

6) Build the RTEMS add-on packages (to get readline)

7) Build 'extended BSP' support.

8) Build EPICS with the attached configure/os/CONFIG_SITE.Common.RTEMS

I tried the above with the RTEMS-4.11 stuff but ran into problems at step (7) -- I couldn't get the the 'libbspExt' stuff to build.  I don't think that there's anything wrong with the source, just the Makefile arrangements seem to have changed between 4.10 and 4.11.  It would be nice if the bspExt stuff could migrate to RTEMS itself….
