[gsoap][C] Undefined SOAP_TYPE_wchar

Question

I'm stuck with gsoap 2.7.13 (wsdl2h v1.2.1 and soapcpp2 v2.7.13). When I tried to map strings to wide chars in a pure C project, I get many compilation errors (SOAP_TYPE_wchar undefined).

Someone have experimented the same issue like me ?

Regards,

My typemap.dat

And my command lines :

wsdl2h -c -o cmis_ws.h -t typemap.dat -x "http://docs.oasis-open.org/cmis/CMIS/v1.0/errata-01/os/schemas/CMISWS-Service.wsdl"
soapcpp2 -c -p cmis cmis_ws.h

The patch to correct this issue:

1. edit gsoap/src/symbol2.c line 11201 and insert

  if (is_wstring(typ)) /* wchar_t* is serializable but wchar_t is transient */
    return 0;

The first part of function is_transient should look like this:

int
is_transient(Tnode *typ)
{
  if (!typ)
    return 1;
  if (typ->type == Tstruct && typ->id == lookup("soap"))
    return 1;
  if (is_external(typ) || is_volatile(typ))
    return 0;
  if (typ->transient > 0)
    return 1;
  if (is_wstring(typ)) /* wchar_t* is serializable but wchar_t is transient */
    return 0;

2. run make again, you can do this in the gsoap/src directory. This builds soapcpp2 in the gsoap/src directory. Copy soapcpp2 to your project or to a bin directory on your $PATH.
