Re: [Quickfix-developers] Question about customized group

[quickfixuser <fw...@ro...>]

Thanks Djalma. Your post is very interesting. It seems quickfix is very
nicely designed. However, though I believe this will work for simple cases,
it seems not work for groups very well. My first problem is that the codes
will stop compiling after I run the script against my modified fix42.xml. I
realized there are duplicate fields generated in some header files though I
have no duplicate fields in xml. Second, the script only run several shared
source file, for a specific class as NewOrderSingle in fix42, I have no xsl
to run aginst. Since the group part need to be part the NewOrderSingle codes
to let it properly added (by addGroup), I still have to manually add it
anyway (please let me know if I misunderstand this part).

I am not familiar with msxml, and maybe I did soemthing wrong, but it seems
to me not work on my case and I finally still have to modify the quickfix
codes directly for this purpose.




Hi,

If you want to use a customized vesion of FIX42::NewOrderSingle, see my post
about regenerating quickfix classes after changing xml files. This is the
easiest way in my opinion.

http://www.nabble.com/Rgenerating-code-after-changing-xml-files-in-spec-fix44-directory-tf3190167.html#a8855920

Basically, you need to change the definition of NewOrderSingle in
FIX42.xmland use spec\generate.bat or spec\generate.sh and recompile
quickfix (if you
are using only C++ I think that this step is not required).

In order to make the script execution faster, comment out the java / .Net
code generation and also FIX versions you don't use in Generator.rb and run
"ruby Generator.rb" or generate.bat, if you are using Windows. It will take
some minutes to generate all the .h files for you.
