Joe,
In the course of playing with QuantLib we've found some problems with
the Java compilation of the QuantLib-SWIG project.
We've made some modifications to the configuration files, please see
the attached patch.
Would be great if this can be included into the HEAD of the
QuantLib-SWIG project.
The diffs are based on the QuantLib-SWIG-0.3.14 release, and i don't
think there have been any changes to the relevant files since the
release.
The patch file expects there to be a directory QuantLib-SWIG-0.3.14
and the changes to be made in a dir called
QuantLib-SWIG-0.3.14_java_patch. However, you can just run it with
'patch -p1 < quantlib-swig_java_ver_1.6-head.patch' in the HEAD of
QuantLib-SWIG and it'll apply the changes.
Also, it seems that there's a discrepancy with the SWIG/options.i file
and the way the Option.Type enum is defined. I think the current file
in the HEAD of SWiG/options.i has the values reversed - the
Quantlib option.hpp file has it this way at
http://quantlib.cvs.sourceforge.net/quantlib/QuantLib/ql/option.hpp?revision=1.41&view=markup enum Type { Put = -1, Call = 1 };
while the SWIG/options.i is
enum Type { Call = -1, Put = 1};
I took the liberty of flipping it to look like the option.hpp file in
the patch as well.
The patch file also contains a small test program Hello.java that does
a basic sanity check to make sure the created Java library works.
And it expects the variable JAVA_HOME to be declared and pointing to
the location of the JDK, and tries to place the generated java wrapper
library into the lib/ directory under the JRE.
hope this helps. please let me know if you need me to change anything,
or if things don't work for you.
