R: Re: R: Re: R: Adding new function to QuantLib XL

tarpanelli@libero.it
Hi ,

may be you can help me on this small homework....

I can build the  xll file adding the stock class as explained into the
tutorial (http://quantlib.org/quantlibaddin/extend__tutorial.html)

What I tried to do it was just insert into the xll a simple inline function
(just for a test).
The steps I followed are:

1. add in QuantLibAddin/qlo the file myfun.hpp having the content:

#ifndef qla_myfun_hpp
#define qla_myfun_hpp

#include <oh/libraryobject.hpp>

namespace QuantLibAddin {
     inline double myfun(double npv)
          {
               return npv;
          }
}
#endif

2. then I've added a new category into QuantLibAddin\gensrc\config\categories.
xml
<categoryName>myfun</Vategoryname>

3. then I added a new xml file into QuantLibAddin\gensrc\metadata\Functions
heving the following contents

<Category name='myfun'>
  <description>test</description>
  <displayName>myfun</displayName>
  <xlFunctionWizardCategory>QuantLib - Financial</xlFunctionWizardCategory>
  <includes>
    <include>qlo/myfun.hpp</include>
  </includes>
  <copyright>
    Copyright (C) 2010
  </copyright>

  <Functions>

    <Procedure name='qlMyFun'>
      <alias>QuantLibAddin::myfun</alias>
      <SupportedPlatforms>
        <!--SupportedPlatform name='Excel' calcInWizard='false'/-->
        <SupportedPlatform name='Excel'/>
        <!--SupportedPlatform name='Cpp'/-->
      </SupportedPlatforms>
      <ParameterList>
        <Parameters>
          <Parameter name='npv'>
            <type>double</type>
            <tensorRank>scalar</tensorRank>
            <description>npv value</description>
          </Parameter>
        </Parameters>
      </ParameterList>
      <ReturnValue>
        <type>double</type>
        <tensorRank>scalar</tensorRank>
      </ReturnValue>
    </Procedure>

  </Functions>

</Category>

4. Then I go to build qlgensrc and I get the following error

fatal error U1077: '..\..\gensrc\gensrc.py' : return code '0x1'


Any clue?

Thanks
Regards,
Paolo

Look further up, in the text that is output before the fatal error.
gensrc should have told you what's wrong in your xml.
