Trouble initiating BSP

[Bill Gatliff]

Guys:


I'm starting on a MIPS-based BSP.  Per some off-list suggestions, I'm 
using the mongoosev CPU and genmongoosev BSP as a starting point.  I'm 
working with rtems-ss-20030703, and things aren't going well.  I'm stuck 
on the basic infrastructure changes needed to get the configure scripts 
to recognize a new BSP and/or CPU, apparently.

My first step is to "clone" the genmongoosev BSP:

   $ cd rtems-ss-20030703/c/src/lib/libbsp/mips
   $ cp -R genmongoosev csb250

Now I create a config file:

   $ cd rtems-ss-20030703/make/custom
   $ cp genmongoosev.cfg csb250.cfg

... and change RTEMS_BSP_FAMILY:

   RTEMS_BSP_FAMILY=csb250

For now, I'm leaving RTEMS_CPU_MODEL at mongoosev, even though my board 
uses the Au1500.  My strategy is to get all the build procedure changes 
right using the mongoosev system before I start adapting it to the 
Au1500.  (I've confirmed that the genmongoosev BSP builds cleanly).

With these changes--- and these changes only---  I get the following result:

   $ mkdir ~/build && cd ~/build
   $ ../rtems-ss-20030703/configure --target=mips-rtems 
--enable-rtemsbsp=csb250 \
      --enable-maintainer-mode 2>&1 | tee configure-log
   ...
    config.status: creating Makefile
   target architecture: mips.
   available BSPs: csb250.
   'make all' will build the following BSPs: csb250.
   other BSPs can be built with 'make RTEMS_BSP="bsp1 bsp2 ..."'
   config.status: creating Makefile
   config.status: creating make/Makefile
   config.status: creating make/custom/Makefile

  $ make all install 2>&1 | tee make-log
   ...

As best I can, I've been following the BSP guide for this snapshot.  I'm 
clearly missing some required changes in the autoconf/automake stuff 
(and perhaps elsewhere), and I'm thinking that part of the problem is 
that I haven't edited any acinclude.m4 files.  But when I do so and run 
the bootstrap script, I get a ton of errors and then even the configure 
script won't work anymore:

Add these lines to libbsp/mips/acinclude.m4:

   ...
     case "$bspdir" in
*     csb250 )
       AC_CONFIG_SUBDIRS([csb250]);;
*     genmongoosev )
   ...

Run bootstrap (which, as far as I can tell, regenerates configure 
scripts and Makefile.ins):

   $ cd rtems-ss-20030303
   $ ./bootstrap
   .
   cp: cannot create regular file `[$1]/install-sh': No such file or 
directory
   automake: configure.ac: installing `[$1]/install-sh'
       error while copying
   ...
   cp: cannot create regular file `[$1]/mkinstalldirs': No such file or 
directory
   automake: configure.ac: installing `[$1]/mkinstalldirs'
       error while copying
   cp: cannot create regular file `[$1]/missing': No such file or directory
   automake: configure.ac: installing `[$1]/missing'
       error while copying
   cp: cannot create regular file `[$1]/config.guess': No such file or 
directory
   automake: configure.ac: installing `[$1]/config.guess'
       error while copying
   cp: cannot create regular file `[$1]/config.sub': No such file or 
directory
   automake: configure.ac: installing `[$1]/config.sub'
       error while copying
   automake: Makefile.am: required file `./NEWS' not found
   automake: Makefile.am: required file `./AUTHORS' not found
   ...

(lots more errors omitted).  Now the configure step gives me this:

   $ cd build
   $ ../rtems-ss-20030703/configure --target=mips-rtems 
--enable-rtemsbsp=csb250 \
      --enable-maintainer-mode 2>&1 | tee configure-log
   checking for gmake... no
   checking for make... make
   checking for RTEMS Version... ss-20030703

   checking target system type... mips-unknown-rtems
   checking for a BSD-compatible install... /usr/bin/install -c
   checking whether build environment is sane... yes
   checking whether make sets $(MAKE)... yes
   ../rtems-ss-20030703/configure: line 1640: foreign: command not found
   checking for working aclocal... found
   checking for working autoconf... found
   ...

(but otherwise appears to run to completion).  And make all ends in this:

   make[7]: Entering directory 
`/home/bgat/bsp250-rtems/build/mips-rtems/c/csb250/lib/libcpu/mips/shared/cache'

So, I've obviously unglued something!  :^)

Suggestions?  I'll be happy to revise the BSP manual as necessary, once 
I get over this hurdle and get my BSP up!


Thanks!
