What is bundle1.o that is added to xlf.cfg in ibm.py in the
get_flags_linker_so() function?

os.name = posix
sys.platform = linux2
I added ibm to _default_compilers for linux.* in __init__.py. But I was
still getting 'None' for compiler.get_version(). In the def
get_version() in ibm.py there is this code:
l = [d for d in l if os.path.isfile(os.path.join(xlf_dir,d,'xlf.cfg'))]
if not l:
from distutils.version import LooseVersion
self.version = version = LooseVersion(l[0])
However 'l' is defined in this case ['8.1'], so I added the else statement
else:
version = l[0]
Now the ibm compiler is detected correctly.
However the build is failing with cannot find 'bundle1.o'. This appears
to be added to the xlf.cfg in ibm.py in the get_flags_linker_so()
function. I am not sure what this does. Let me know if this is AIX
specific. Also, in the same function '-bshared' is added as an option
for the linker. As far as I can tell there is no such option for the
8.1 (or 9.1) versions of the compiler for Linux.
Continuing..
