Since gcc doesn't actually produce object files, it would
probably be binutils/gdb that are out of sync.

If you want to send me your ELF file (or put it somewhere I can
download it), I could try loading it with gdb 5.1.1.

Hi,
here's a copy of what happens:
$ msp430-gdb --se=test_1
GNU gdb 6.0
Copyright 2003 Free Software Foundation, Inc.
GDB is free software, covered by the GNU General Public License, and
you are
welcome to change it and/or distribute copies of it under certain
conditions.
Type "show copying" to see the conditions.
There is absolutely no warranty for GDB. Type "show warranty" for
details.
This GDB was configured as "--host=i686-pc-cygwin
--target=msp430"..."/home/tst/
LCD/test_1": not in executable format: File format not recognized
(gdb) file test_1
"/home/tst/LCD/test_1": not in executable format: File format not
recognized
(gdb)
Is it possible that the new version of msp-gcc isn't compatible with
msp-gdb?
I downloaded it all from Sourceforge 3 days ago.
Cheers,
Martin.

That looks right. If msp430-objdump recognizes the file as an
MSP430 ELF file and msp430-gdb doesn't, then msp430-gdb must be
broken.
Can cut/paste a sample gdb session into a posting?

Hi,
yeah I tried naming the binary test.elf, test and test_1 just in case.
I simply renamed the same file each time.
I ran "msp430-objdump --section-headers test_1":
test_1: file format elf32-msp430
Sections:
Idx Name Size VMA LMA File off Algn
0 .text 00000780 00001100 00001100 00000094 2**1
CONTENTS, ALLOC, LOAD, READONLY, CODE
1 .data 00000002 00000200 00001880 00000814 2**1

4 .stabstr 00002879 00000000 00000000 00002404 2**0

That certainly indicates that the binary file is ok.

After thinking about it more, I do remember that many years
ago, the Cygwin-hosted Gnu linker had a bug where if you
specified a filename without a "suffix", it would create an
output file with ".exe" tacked onto the name of the file even
though the file definitely wasn't a ".exe" file. That fun
little bit of brain-damage caused a lot of Makefiles to break.
But, I thought that was fixed a long time ago.
In any case, I don't see how that problem would have caused the
symptoms the OP is reporting.

That only matters if you're trying to run a program named
"test" from the shell without specifying a path. Some shells
have a built-in named "test". Other shells will find the "test"
executable in /usr/bin.
However that has absolutely no impact on creating or using a
file named "test" in other contexts.
> So you might have use another name after -o
Using a file named "test" is perfectly fine.
For non-native ELF files, I generally use a ".elf" suffix, but
that's purely a matter of personal taste: Unix doesn't care
least if I want to name a file "test" or "test.elf".
> or use './test' at the prompt.
It doesn't matter. It's not a program he's trying to execute
from a shell prompt, so there's no difference between using
"test" and using "./test":
$ echo "hi there" >test
$ cat test
hi there
$ file test
test: ASCII text
$ wc test
1 2 9 test
$ tr '[a-z]' '[A-Z]' <test
HI THERE

In a *NIX environment test is a reserved word: man test
So you might have use another name after -o
or use './test' at the prompt.
HTH, I don't suscribet do a msp430 mailing list.

Is the name of the object file created by msp430-gcc "test" or
"test.elf"? The command line you showed in your posting on the
mailing list was creating "test.elf", but then you were trying
to do things with a file named "test".
Where did the file "test" come from?

That depends on which command line you really used -- the one
you posted on the mailing list, or the one you posted here.
What do the following commands display?
msp430-objdump --section-headers test
msp430-objdump --section-headers test.elf

Hi,
hadn't seen your reply! My messages have to be vetted for the mailing
list and so take a little longer. As you can see I tried "file test"
and msp430-gdb replies that it doesn't recognise the format. This
doesn't make any sense since msp_gcc created the executable.
Cheers,
Martin.
