I don't know either which AIX version your customer runs, but there is a BIG chance it isn't AIX 5.3 of any sort at all. 5.3 is not supported any more since a some years now (even its successor 6.1 is almost out of support) and on newer (POWER8) systems it won't even run. On the other hand the recent AIX version (7.2) will not run on POWER5 or even POWER6 platforms.

From 5.3 to 6.1 and from 6.1 to 7.1 there were two big changes and - lacking intimate knowledge of your application - it is quite conceivable that your code might have problems running on current platforms and/or OS versions.

To what agent.kgb (rightfully) said i'd like to add: get a current platform to compile your software, POWER7 at least or preferably a POWER8.

I hope this helps.

platform

platform(n)						       Tcl Bundled Packages						       platform(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform - System identification support code and utilities

SYNOPSIS

       package require platform ?1.0.4?

       platform::generic
       platform::identify
       platform::patterns identifier
_________________________________________________________________

DESCRIPTION

       The platform package provides several utility commands useful for the identification of the architecture of a machine running Tcl.

       Whilst Tcl provides the tcl_platform array for identifying the current architecture (in particular, the platform and machine elements) this
       is not always sufficient. This is because (on Unix machines) tcl_platform reflects the values returned by the uname command and	these  are
       not standardized across platforms and architectures. In addition, on at least one platform (AIX) the tcl_platform(machine) contains the CPU
       serial number.

       Consequently, individual applications need to manipulate the values in tcl_platform (along with the output of system specific utilities)  -
       which is both inconvenient for developers, and introduces the potential for inconsistencies in identifying architectures and in naming con-
       ventions.

       The platform package prevents such fragmentation - i.e., it establishes a standard naming convention  for  architectures  running  Tcl  and
       makes it more convenient for developers to identify the current architecture a Tcl program is running on.

COMMANDS

       platform::identify
	      This  command returns an identifier describing the platform the Tcl core is running on. The returned identifier has the general for-
	      mat OS-CPU. The OS part of the identifier may contain details like kernel version, libc version, etc., and this information may con-
	      tain dashes as well.  The CPU part will not contain dashes, making the preceding dash the last dash in the result.

       platform::generic
	      This  command  returns a simplified identifier describing the platform the Tcl core is running on. In contrast to platform::identify
	      it leaves out details like kernel version, libc version, etc. The returned identifier has the general format OS-CPU.

       platform::patterns  identifier
	      This command takes an identifier as returned by platform::identify and returns a list of identifiers describing compatible architec-
	      tures.

KEYWORDS

       operating system, cpu architecture, platform, architecture
