Re: [tbox-l] libm.a not a COFF file

What level AIX are you on? What level libm? ("lslpp -l bos.adt.libm").
Those look like they match the dates/sizes from a 4.3.3 system.
Are you trying to link 64-bit objects using gcc? If so, add "-maix64"
to you arguments. For 32-bit, I don't see anything wrong with the command.
But, there is not a separate 64-bit libm; the 64-bit objects are also
in the same archive, so your "ar -X64 -tv libm.a" command *should* show them.
Unless....
OK, here's a theory: You are on a 5.1 or 5.2 system, and instead of
installing the "bos.rte.libm" for your OS level, somebody has copied
/usr/ccs/lib/libm.a from a 4.3.3 system onto your 5.2 system.
Could that be it? If so you'll want to install the correct level
of bos.adt.libm.
