Re: New User - Help!

Hi Eric

Once again thanks for your input.

You are correct about the Axiom board. I have uploaded a sample 
application into the RAM and run it using the monitor program. I now 
want to compile the sample program supplied and this is where my 
problems start.

The Axiom support CD supplies a simple 'hello world' application that 
it states was compilied with the Diab compiler....however when I try 
to compile the application as supplied I get error messages as below:

------------------------------------------------------------------
C:\diab\5.2.1.0\src\hello>hello_r

C:\diab\5.2.1.0\src\hello>dcc -tPPC555EN:simple serial.c hello.c -o 
hello_r.elf
-g -XO -Wmhello_r.dld -m2  1>hello_r.map
dld: warning: Don't know where to allocate input section:
dld:   no matching input specification found in linker command file.
dld:   Section name: .ctors
dld:   File: ctordtor.o(C:\Diab\5.2.1.0\PPCE\libimpl.a)
dld: Unable to link without .ctors or .dtors section allocation

C:\diab\5.2.1.0\src\hello>ddump -R -v -o hello_r.s19 hello_r.elf
ddump: warning Can't open file hello_r.elf: No error
ddump: warning
hello_r.elf : Unrecognized file type.  Neither COFF nor ELF
------------------------------------------------------------------

It is obviously down to some linker issue. I emailed Axiom but still 
have received no response. Let's hope they reply soon!

Best regards
