This file describes some things to be aware of when building SIP (and PyTQt)
|
|
under AIX.
|
|
|
|
I had success building SIP V3/V4 (and PyTQt) on AIX 4.3.3 and on AIX 5.1 with
|
|
VisualAge C++ and with gcc.
|
|
|
|
VisualAge C++ was version 6.0 but it should also work with version 5.x.
|
|
The GNU compiler was version 3.3.2 downloaded as a binary from
|
|
http://aixpdslib.seas.ucla.edu/aixpdslib.html
|
|
|
|
The TQt-Version was 3.2.3 but it should also work with previous versions.
|
|
|
|
If you are using Python version 2.3.3 or higher, SIP (and PyTQt) should build
|
|
out of the box without any changes.
|
|
|
|
If you are using a Python version before 2.3.3, you have to patch Python,
|
|
because until this version, Python uses the system calls load() and
|
|
loadbind() to load and bind shared objects. These system calls cannot load
|
|
and bind C++ shared objects properly (constructors and destructors for static
|
|
classes are not called with these system calls). Since AIX version 4.2 the
|
|
system calls dlopen() and dlsym() are available and should be used in
|
|
preference.
|
|
|
|
The following patch changes the configure script of Python to use dlopen()
|
|
and dlsym() if they are available. It also fixes a bug with the definition of
|
|
_XOPEN_SOURCE:

Note: I did not mix the compilers when building TQt, Python, SIP and PyTQt. At
|
|
least TQt, SIP and PyTQt must be built with the same compiler because of
|
|
different name mangling schemes.
|
|
|
|
If you have any problems or questions on building SIP or PyTQt on AIX, either
|
|
send an email to ulrich.berning@desys.de or use the PyKDE mailing list.
