Hi ,

I wrote a simple "hello world" program on AIX5.2 using gcc compiler .

The resultant binary exe(name - getpqstatus) when i ran on AIX5.1 it
is giving the
below error :

exec(): 0509-036 Cannot load program ./getpqstatus because of the
following errors:
0509-130 Symbol resolution failed for getpqstatus because:
0509-136 Symbol __strtollmax (number 15) is not exported from
dependent module /usr/lib/libc.a(shr.o).
0509-192 Examine .loader section symbols with the
'dump -Tv' command.


Does anyone has any idea why this is happening ..? Does even simple
programs compiled in AIX5.2 do not run on AIX5.1 ...?


Any help will be really helpful and appreciated ...


Thanks and Regards
Sona .

H'llo Sona,

What you're trying to do is not possible. AIX is being maintained in
such a way that older programs will still run on the newer versions of
AIX. The other way round, however, is not guaranteed.

Apparently, the strtollmax() function was only invented in AIX 5.2, and
AIX 5.1 doesn't have it.

The golden rule is: whenever you want to support multiple versions of
AIX, compile it on the oldest version you want to support. It will
*usually* work on the newer versions as well.

Cheers,
Menno

I can't recall any operating system (or large program) for which one could
expect reverse compatibility (the problem is not specific to AIX).

Try option control various sorts of optimizations -O3 with gcc

That is *supposed* to happen: no UNIX system I know supports
compiling on newer system and running on older.

Because the set of symbols exported from libc.a is bigger on AIX
5.2 then on AIX5.1, and because some code you linked in (probably
from libgcc) depended on a symbol that is not available on AIX5.1

In general, no.

You should build on the *lowest* version you plan to support
(i.e. build on AIX 5.1, and it will work fine on AIX 5.2).
