Problem with gensrc

[Nicolai Lassesen]

Hi all

I have a problem when I try to build QuantlibXl, ObjectHandler, etc. with the
gensrc projects - these fail to autogenerate the code they are supposed to. I
am compiling the projects in Visual C++ 2008 Express, but I suspect the
problem is related to python, I am using version 3.0.1.

Upon build the following output is generated for the ohgensrc project:
1>------ Build started: Project: ohgensrc, Configuration: All Win32 ------
1>Performing Makefile project actions
1>Microsoft (R) Program Maintenance Utility Version 9.00.30729.01

1>ohgensrc - 2 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

- and similar for the qlgensrc project. Later projects fail to compile because
the autogenerated files are missing.

Does anybody have any comments on this? Has anybody else been able to build
with python version 3.0.1?

Hi Nicolai,

Yes, your problem is related to python, specifically to python version
3.0. The reason is that python is intentionally *not compatible*
between versions 2.x and 3.x.

For the case of the error message you have, you are tripped up by the
change in the "print" functionality: in 2.x print is a statement, in
3.x it is a function.

You need to install python 2.x or, if you are ambitious, try running
an automatic converter that changes 2.x code into 3.x code.

Best,
Bojan

Hi Bojan

Thank you for your reply.

I was not aware of this incompatibility - maybe someone should put a note on
the Quantlib site :-)

I tried editing the python files, altering "print " to "print(...)" and
various other stuff, but when the compiler began to complain about the xml
files as well I gave up and installed the 2.6.1 version of python - now
everything runs and compiles just fine :-)

Br,
Nicolai
