I am trying to load some XML data into C++ code (classes) using gsoap.

  • 0

I am trying to load some XML data into C++ code (classes) using gsoap. In the examples they have in the documentation they talk about loading web services documents to C++ headers (wsdl2h); but there were no explicit examples using XML files directly. Anyways, I installed gsoap (using pre-compiled binaries) and tried as a first step, doing: 

wsld2h -o <myexample_cpp.h> <myexample.xml>

and I got:

../../bin/linux386/wsdl2h: ../../bin/linux386/wsdl2h: cannot execute binary file

As a last note, I am testing this in Cygwin (using the linux binary), but I doubt that might contribute to any error. Also I wanted to know if the XML file has to have the “xml” extension in order for it to work? Appreciate if anyone with some ideas can share their experiences.

Edit:
Actually this could be due to running the linux pre-compiled binary on cygwin. Anyway I tried this from the Windows command line instead and I got what appears to be a legitimate error:

  <path/to>\tests\gsoap>..\..\bin\win32\wsdl2h.exe -o myexample_soap_cpp.h myexample.xml

    Actually, I resolved this. The problem was the usage. I need to be issuing the wsdl2h executable with the XSD schemas as argument, not the XML files. That fixes all the errors (I tested this only on Windows 64 bit Vista). Thanks.
