Topics

• Setting up IBM LoP SDK

• Import sample Code to SDK

• Build, analyze code and execute.

• Using Migration Advisory tool.

• Familiarizing with SDK plugins


Setting up IBM LoP SDK

• Installation documents and Binaries are available at–https://www-304.ibm.com/webapp/set2/sas/f/lopdiags/sdklop.html

• Using the software repository package, installation is just 3 step process.

Install the IBM PowerLinux Repository initialization RPM package. This will define repository in the system.

Run update on the repository.

Install IBM SDK Package using commands like Yum or Zypper Will automatically download the all the necessary packages

from internet and completes the installation


Setting up LoP on a standalone/Isolated System

Download ISO image of IBM SDK from IBM site.

Download the Advance Tool chain -ftp://ftp.unicamp.br/pub/linuxpatch/toolchain/at/

Define Repository of for packages downloaded (using package managers such as zypper , yum etc)

Install the SDK tools using Package manager


• SDK can be run as a user• Concurrent multiple users are possible.• Some advance plug-ins need root privileges

• Select the path for your unique Workspace.

• Needs a Graphics User interface – such as X windows or VNC

• Default Installation path is /opt/ibm/ibm-sdk-lop

• Execute ibm-sdk-lop to launch the SDK

• SDK can be run as a user• Concurrent multiple users are possible.• Some advance plug-ins need root privileges

• Select the path for your unique Workspace.

Launching IBM LoP SDK


Create a simple C Project

Create an empty Project

Specify a name for the project & select Advance toolchains

Import a C Code


Build project and analyze views

Building the Project • Most menu options in SDK can be accessed directly by right clicking on the project in the Project explorer view

Check out the views on the bottom half of the SDK.

Note the Console and Problem Window Console window shows similar output as one would see in Shell window Problems window lists out all issues found during build.

If views are not visible or are accidentally closed, they can be opened from the Window Menu

Double clicking on issues in the Problems view, will show the line of code of concern. Hovering the mouse over it provides more details on the issue and in some cases an autofix option


gdb/server option is used if the binaries need to be run remotely on a ppc system. Cleints can reside on x86 linux system

Running the project

Running the imported C code.

Output is shown in Console window view


Behind the scene – Files and Layout

Check out how files are laid out in the filesystem

Note : Makefile is generated automatically for the sample C code imported.

Here is a sample of Makefile generated


Migration Advisor & import a makefile project

Importing an existing Makefile project and a new project.

Choose a name for the project and Select the path of the source.

Run Migration Advisor

Plug-ins are installed on the system,but may need enabling if you get this message:


Migration Advisor(Cont.d)

• Enabling the Migration advisor Plugin

–This maybe required the first time when the tool is run.

–Enable Linux/x86 to PowerLinux application Migration.

Run Migration Advisor tool after enabling features.

In some cases Autofix solutions are offered for issues .. Note the inserted code fixes do preserve exisiting platform specific codes
