RE: Run objdump under windows XP for XCOFF object file created from IBM AIX system

[David Du]

HI, Ben, thanks for your response, I checked and redid my testing, I used
the right objdump.exe file, after I did make all and built the binutil, all
the  exe files are under the binutils directory, so I just ran the
objdump.exe file under that directory, ./objdump -i, and also I tried and
changed the objdump.exe of cygwin to objdump1.exe, and the objdump.exe under
binutils directory to objdump2.exe, ran each of them, here is the results:
And also I configured the target to just rs6000-aix, and build the binutils
and then ran make install, they then were installed under
cygwin/usr/local/bin directory, called rs6000-aix-objdump.exe, after I ran
this file, it said invalid target as shown in the following:

Any other idea what is wrong?

THanks for your help.

David


This is from cygwin:

THis one is from binutils, I rename it to objdump2:

$ which objdump2
./objdump2
$ objdump2 -i

THis one is after I configure target to rs6000-aix and ran make install:

C:\cygwin\usr\local\bin>rs6000-aix-objdump -i
rs6000-aix-objdump: can't set BFD default target to `rs6000-ibm-aix':
Invalid bfd target

At the risk of being the next bunny to answer a spate of newbie questions ..

David, it sounds like you aren't running the right objdump.  You may have
one
installed with Cygwin already.  When you build binutils, where are you
installing it
with `make install'?  Are you sure that when you run `objdump', it's the one
you're
expecting?  Try `which objdump' to be sure.
