[xsd-users] Cross compile c++ classes to use in openwrt

[Micael Santos]

Hello,

Recently I have been trying to use codesynthesis to generate c++ classes from a xml schema for an embedded board that uses openwrt as it's operating system.
So far I have been able to compile the xerces-c library using the feed bellow and it seems to be working fine.
https://github.com/openwrt/packages/blob/master/libs/libxerces-c/Makefile

Now when I try to execute the "hello world" example bellow I can't make it work on my board. But when I try it on my PC works fine.
http://www.codesynthesis.com/projects/xsd/documentation/cxx/tree/guide/#2

I'm using eclipse to do the cross compiling which is been working fine for the other code using the following setttings
                Included libraries -   xerces-c
                Compiler - i486-openwrt-linux-g++

I installed the package "xsd_4.0.0-1_i386.deb" on my computer in order to able to generate the c++ classes using the command
$ xsd cxx-tree hello.xsd

The only thing I had to "cheat" was copying the folder "/usr/include/xsd" to my cross compiler includes folder. I think probably the copying of the header was not the way to go  but since it compiled afterwards I assumed it was ok.

The problem is that I can't make the program run, getting the following output. When I compile it and run it on my pc without the cross compile it works fine.

/tmp/hello.xml:1:29 error: no declaration found for element 'hello'
/tmp/hello.xml:1:39 error: no declaration found for element 'greeting'
/tmp/hello.xml:1:61 error: no declaration found for element 'name'
/tmp/hello.xml:1:77 error: no declaration found for element 'name'
/tmp/hello.xml:1:94 error: no declaration found for element 'name'
Segmentation fault

I tried everything that crossed my mind so far without luck. Anyone has any ideia what I'm making wrong?
Do I need to compile the entire "XSD" using my cross compiler? And if so how will I call xsd from my pc since it was compiled for other platform?
I'm sure must be something really simple but I'm kinda stuck :(

Thanks for the help
