Hi all,
Using this code as example:
/*----------------------------------------------------------------------------
Class: CPsXmlHlp
Description:
XML extraction helper.
----------------------------------------------------------------------------*/
class CPsXmlHlp
{
public :
CPsXmlHlp();
virtual ~CPsXmlHlp();
static U32 GetU32Value(const TiXmlNode* Node) throw(CPsXmlHlpError)
// Returns the value of an XML element
{
if (!Node)
throw CPsXmlHlpError("GetU32Value: Node is NULL", NULL);
return atol(Node->ToElement()->Attribute("index"));
}
static R64 GetChildR64Value(const TiXmlNode* Node, const char* Name)
throw(CPsXmlHlpError) // Returns the value of an XML element
{
TiXmlNode* ChildNode = Node->FirstChildElement(Name);
if (!ChildNode)
throw CPsXmlHlpError("GetChildR64Value: Item Not Found", Name);
return atof(ChildNode->ToElement()->Attribute("value"));
}
static U32 GetChildU32Value(const TiXmlNode* Node, const char* Name)
throw(CPsXmlHlpError) // Returns the value of an XML element
{
TiXmlNode* ChildNode = Node->FirstChildElement(Name);
if (!ChildNode)
throw CPsXmlHlpError("GetChildU32Value: Item Not Found", Name);
return atol(Node->FirstChildElement(Name)->Attribute("value"));
}
private :
// Not implemented, to prevent automatic generation and use
const CPsXmlHlp& operator =(const CPsXmlHlp&);
CPsXmlHlp(const CPsXmlHlp&);
};
Using the 2.9.5 compiler, I get linker errors
/appl/sde/home/scheinr/public_html/work/atarps.prj/atarps.exe/atarps_sim.mod/PsUtil.cpp:617:
undefined reference to `CPsXmlHlp::GetChildU32Value(TiXmlNode const *, char
const *)'
If I remove exception handling, the application builds successfully. Is there
a known bug with exception handling in this compiler version? Is there a
compiler switch I'm missing? What may be a good workaround?
Thanks in advance,
