Hi Bernard,
Yes I would agree compiling msp430-gcc is complex,
there are quite a few pieces that all need to hang together to make it
work, and many of the tools are changing also. A lot of the problem is
the support for the ever increasing number of devices in all parts of
the tool chain (binutils, gcc, msp430-libc, gdb and gdbproxy are all
affected by new devices).
I did also find that the patches for binutils 2.18 didn't work for 2.19,
although I think I have a working build for 2.19 now.
The
windows build is done using the makefiles and scrips in the packaging
directory, this way the source for the tools is controlled and its a
package we know works.
Yes there is a problem with binutils-2.18
and a modern compiler because its header files specify that the return
value should be checked, I found that this had been fixed in
bintuils-2.19. Attached is a patch that fixes this problem for
binutils-2.18
Looks like we have to roll some of this into the packaging directory, and get
patches working for 2.19.
I had to use make MAKEINFO=/usr/bin/makeinfo to get binutils-2.18 to find
makeinfo on ubuntu
Hope that helps,
Peter

Hi Peter,
Compiling the tools is becoming a real pain. I have never had trouble like this
compiling mspgcc in the past ( a year or two ago..).
I have applied the patches fine to a fresh get of binutils-2.18 (these patches
would not work for 2.19).
However when I tried to compile 2.18 I now get this error.

Any further ideas? Do I also have to patch the msp430-gcc compiler with the
appropriate files from the packages/patches directory?
It seems pretty bad to me that you can't build the tools with "released"
versions because of the "released" msp430-libc !!..
Cheers,
Bernie

Ok If you use binutils 2.18 (or 2.19) then you need to apply the patches in
http://mspgcc.cvs.sourceforge.net/viewvc/mspgcc/packaging/patches to get
support for the 2001 device.
You get get these files from cvs by,
cvs -z3 -d:pserver:[email protected]:/cvsroot/mspgcc co
packaging
apply these to the binutils tree,
eg
cd binutils-2.18
export PATCHES=../packaging/patches
patch -p1 <
$(PATCHES)/binutils-2.18-14x1-20x1-20x2-20x3-22x4-42x-42x0-461x.patch
patch -p1 < $(PATCHES)/binutils-2.18-msp430x24x-msp430x26x.patch
patch -p1 < $(PATCHES)/binutils-ld_scripts.patch
patch -p1 < $(PATCHES)/binutils-2.18-430X.patch

The version of gcc to use is 3.2.3 (as on the web page), gcc-4.x does not work,
3.2.3 is the only choice and is the one that the latest devices have been added
too.
