I have a problem with an executable.

It shows this message when I try to run the executable



exec(): 0509-036 Cannot load program Algorithm because of the
following errors:

0509-130 Symbol resolution failed for Algorithm because:

0509-136 Symbol select (number 46) is not exported from

dependent module /unix.

0509-192 Examine .loader section symbols with the

'dump -Tv' command.



The dump -Tv of the executable shows this :



***Loader Section***

This happens on AIX 5.1.0.0.

I have AIX 4.3.2.0 installed on another machine and the executable works
fine there.



I've understood it's a problem with the select function which is not
exported from the /unix module but don't know what the /unix module is
and where I can find it.



Can someone please help me with this problem?

Many thanks.

looks like your binary is incompatible. are you running 64bit 5.1 kernel
?

PS. if you don't know what /unix is then you are in all sorts of
trouble.....



I would suggest you start reading the docs.



http://publibn.boulder.ibm.com/cgi-b...US&viewset=AIX



Or search the redbooks site for AIX and Certification, there are some
good admin redbooks out there.



Once you have a handle on it, then you can look at symbol resolution and
how it works.

Thanks for the reply Mark,

I think it is a 64bit 5.1 kernel because this command lsattr -E -l
proc0 returns this :



state enable Processor state False

type PowerPC_RS64-III Processor type False

frequency 500040000 Processor Speed False



On the machine with a 4.3 kernel, the command lsattr -E -l proc0
returns this :



state enable Processor state False

type PowerPC_RS64-II Processor type False



Therefore I think it is a 64bit kernel as well (according to the
processor type) and the executable works well there.



My knowledge of AIX is limited anyway.



I think the select() function is in libc.a and it has not moved from AIX
4.3 to 5.1 apparently and I don't think the XCOFF structure has changed
also. I don't really understand what is the problem.



Any help is appreciated. Thanks.



Regards.

lsattr -EHL on the processor will just tell you if the h/w is 64
bit.....



64 bit h/w can run 32 bit or 64 bit kernel



bootinfo -K will tell you what kernel is loaded.



i.e.

bootinfo -K

32



means i am running 32 bit kernel.

also, a binary complied on 4.3.2 will run on 5.1 32 bit, but not 5.1 64
bit, it will need to be recomplied.

Thanks.



I don't have root access on the servers to execute the bootinfo command
but after investigation, it appears that both kernels are 32bit.



Therefore I shouldn't need a recompiled binary, should I?

Do you have any other idea please?



Many thanks.

1st check for this apar



instfix -ik IY38440



then: lppchk -v --> any broken filesets ?



echo $LIBPATH --> /usr/lib ?

instfix -ik IY38440 returns this (on both machines) :

There was no data for IY38440 in the fix database.



And lppchk -v doesn't return anything (I suppose there's no broken
fileset then).



The LIBPATH is not set on any machine. I have tried to set it to various
values, including /usr/lib but it doesn't work (although libc.a is
present in that directory).



Is there a way to know which library the binary uses on the AIX 4.3.2
(so I can use the same on the other machine)?



Thanks a lot.
