Info

work as on previous releases of AIX. As on earlier releases of AIX, IBM will also ship X11R3, X11R4, and X11R5 compatibility installation options for maximum customer flexibility. In this way, client applications will experience no problems with compatibility. The majority of applications using X fall into this category and will not have any difficulties. However, a small number of X applications use the loadable extension facility provided by the X server. The X-server allows for the addition of new function through its extension mechanism. For each extension, part of the extension is loaded into the X-server before it can be executed. X11R6 has modified this mechanism, and it is this part of the extension that must be made compatible with X11R6 to execute properly. All extensions supplied by IBM have been made compatible and will execute properly. In some circumstances, a customer may have an extension that will not work with X11R6, such as: • Customers who have sample extensions downloaded from the X Consortium FTP site. • Customers who have developed their own extensions. • Customers using third-party extensions. In these cases, the extensions will need to be made compatible with X11R6 before they will execute properly. Customer-developed extensions and sample X consortium extensions will need to be recompiled with the X11R6 environment. For third-party extensions, the customer should contact the vendor for a X11R6-compatible update. Customers using non-IBM display adapters may also be using vendor-supplied software specific to those devices that use X-server capabilities. If so, this software must be made compatible with X11R6 to operate properly. The customer should contact the vendor of the display adapter for this software. IBM provides a porting guide with AIX Version 4.3 that also appears on The Developers Connection CD to assist customers and vendors developing adapters or extensions for AIX. The Developers Connection can be found at the following URL: http://www.developer.ibm.com/devcon/ 2.1.3 AIX Version 3 Application Compatibility All AIX applications correctly written using AIX Version 3 Release 2 or greater for POWER, POWER2, and PowerPC-based models will run on AIX Version 4 without recompilation for the same models. Exceptions are applications that use: • Their own loadable kernel extensions • Certain High Function Terminal (HFT) control interfaces • X11R3 input device interfaces • The CIO LAN device driver interface • SCSI device configuration methods (IHVs) • The nlist() interface • DCE threads 14 AIX Version 4.3 Differences Guide
Other exceptions include applications compiled using POWER2 or PowerPC-specific compiler options that run on models other than POWER2 or PowerPC. Any program designed to run in all environments, that is, POWER, POWER2 and PowerPC (601 and above), must be compiled using the common mode option of the compiler. Programs compiled to exploit POWER2 technology must be run on POWER2-based processors. Programs compiled to exploit PowerPC-based technology must be run on PowerPC-based processors. Existing code does not need to be recompiled to run. Note: Applications created on a system using AIX Version 4 may not function properly on a system using AIX Version 3. For these statements to apply, applications must have been created using the AIX shared libraries. 2.1.4 Client/Server Application Compatibility An RS/6000 system using AIX Version 3 Release 2 or greater can operate as a server system for client machines using AIX Version 4 with the following exceptions: • Service of Version 4 diskless/dataless machines • Network install of Version 4 clients • Service SNA or X.25 to Version 4 clients • Service HCON to Version 4 clients • Service CGE extensions of PEX and PEX-PHIGS • Use of AIX Version 4 client install formats An AIX system using AIX Version 4 may operate as a server system for client machines using AIX Version 3 Release 2 or greater as long as the proper compatibility options are installed. All statements about binary compatibility apply in this case. Version 4 applications may not execute properly on Version 3 systems using remote network mounts of file systems. In both cases, minor administrative changes must be made to the AIX Version 3 systems to support the new AIX Version 4 LFT terminal type. 2.1.5 IBM Licensed Program Products Compatibility There are hundreds of Licensed Program Products (LPP) available for AIX Version 4. IBM LPPs currently sold for AIX Version 4 Release 1 or Release 2 will operate without change on AIX Version 4 Release 3 with certain exceptions, such as newer versions or releases of a product being available. For information about a specific LPP, the AIX Version 4 IBM Licensed Program Products RoadMap can be found at the following URL. http://www.rs6000.ibm.com/software/Apps/LPPmap.html This document contains information about latest LPP version levels, support, and AIX release compatibility.
