- Secondary build host (if the AIX on the main build host is too low-level, e.g., for some C++ stuff)
- My main build host for AIX5L v5.1 is running AIX 5.1 ML 09.
- I use the IBM XL C/C++ compiler version 7 with all applicable patches for AIX 5.1 ML 09.
Compiling on AIX5L v5.2
- My build host for AIX5L v5.2 is running AIX 5.2 ML 01.
- I use the IBM XL C/C++ compiler version 7 with all applicable patches for AIX 5.2 ML 01.
Compiling on AIX5L v5.3
- My build host for AIX5L v5.3 is running AIX 5.3 ML 01.
- I use the IBM XL C/C++ compiler version 7 with all applicable patches for AIX 5.3 ML 01.
Compiling on AIX v6.1
- My build host for AIX v6.1 is running AIX 6.1 TL 00.
- I use the IBM XL C/C++ compiler version 9 with all applicable patches for AIX 6.1 TL 00.
Compiling on AIX v7.1
- My build host for AIX v7.1 is running AIX 7.1 TL 00.
- I use the IBM XL C/C++ compiler version 11.1 with all applicable patches for AIX 7.1 TL 00.
IBM XLC/C++ vs. GCC
- I always try to use the IBM XL C/C++ compiler.
- Only if it is absolutely not possible to build the software with XLC/C++ I use GCC (e.g., lftp). The "drawback" is that this requires in most cases that libgcc must be installed on the system.
- Some exceptions exist, e.g., Perl is intentionally built with GCC.
Environment settings XL C/C++
- I always use the BASH shell (from this web site).
- For the different AIX versions I use exactly the environment settings listed below, i.e., you need to put those statements in you
.bashrc so that they are activated.
- If any different settings are required they are explicitely specified in the SPEC file contained in the Source RPM (SRPM) file.

Source code and SPEC files
Remarks
- I always provide the source code as well as all patches and the SPEC file. The only exception is GCC where the source code is linked directly to the GCC GNU website as this package is so big in size.
- All this is contained in the SRC RPM file that you find exactly on the same webpages as the binary RPM. Here are direct links to all
- The SRC RPM is installed in the same way as binary RPMs, e.g.,
rpm -ivh <package>-<version>.src.rpm
Afterwards you'll find the sources and patches in /opt/freeware/src/packages/SOURCES and the SPEC file in /opt/freeware/src/packages/SPECS.
- Here is an example how you can extract the
abc-1.2.3-1.src.rpm SRC RPM file into a local directory tmp:
mkdir tmp
cd tmp
rpm2cpio <path-to-SRPM>/abc-1.2.3-1.src.rpm | /opt/freeware/bin/cpio -idm
Note: You need GNU cpio as AIX cpio produces I/O errors.
Building the binary RPM file
- Start out in the directory
/opt/freeware/src/packages/SPECS.
- Normally, I use the following command to generate the RPM (binary and source) packages:
rpm -ba <SPEC-file>
- However, whenever there is Perl somewhere involved I use the following command instead:
PATH=/opt/freeware/bin:$PATH rpm -ba <SPEC-file>
- To build only the binary RPM package:
rpm -bb <SPEC-file>
- To build only the SRC RPM package:
rpm -bs <SPEC-file>
