RE: gcc v3.4.4; templates and compile errors

[Magyar, Thomas J. CIV NAVAIR]

Thanks Corey, I did file a bug report and it has already been confirmed. It will be fixed in 3.4.5 release. 

Thanks, 

Tom

You are right! Ugggh, all of those 'template's and 'typename's is starting to make my eyes blurry. Thank you!

RE: gcc v3.4.4; templates and compile errors

[Magyar, Thomas J. CIV NAVAIR]

I have found the fix to this compiler error! I re-read the email sent by Corey once again this morning and found that I missed placing the 1st 'typename' at the beginning of the line. I had only put in the 2nd one, which resulted in an internal compiler error (see my previous reply). 

Once I added that one, I got back to getting compiler errors that I could process through. It turns out that the line will get past the compiler with no warnings if it looks like below (with the 'template' keyword added):

typename SAX::basic_XMLReader<stringT>::template Property<typename SAX::basic_DeclHandler<stringT> *>* prop;


Now, I have one last similiar compile error in this file and hopefully I am home free. Here is the function (with my attempt at fixing it with 'template' and 'typename' and the output:

template<class stringT, class string_adaptorT>
327 void libxml2_wrapper<stringT, string_adaptorT>::doSetProperty(const stringT& name, typename std::auto_ptr<typename basic_XMLReader<stringT>::PropertyBase> value)
328 {
329   typename SAX::basic_XMLReader<stringT>::template Property<declHandlerT&>* prop;
330   prop = dynamic_cast<SAX::basic_XMLReader<stringT>::template Property<declHandlerT&>*>(value.get());
331
332 ...
333
334   return;
335 }

/saxlibxml2.h:330: error: expected template-id for type before '*' token

I corrected line 329 with the addition of 'typename' and 'template' as it was giving me errors first. But now I can't figure out what combination to do for 330. I have only added the 'template' keyword so far. Previous to that addition, I was getting:

/saxlibxml2.h:330: error: 'class SAX::basic_XMLReader<string_type>::Property' is not a type.

I think this is my last hurdler, hopefully one of you can recommend a solution!

Thanks,

Tom

I really don't know about that.

You could file a bug report or maybe others here have a response?

RE: gcc v3.4.4; templates and compile errors

[Magyar, Thomas J. CIV NAVAIR]

Thanks for the quick reply. I'm taking a look at that changes documen now. 

I just tried your possible fix by adding the "typename" keyword where you specified. I think I may have tried that before. Here is what happens on that line!!?

.../SAX/wrappers/saxlibxml2.:310: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
gmake: *** [../../Include/SAX/wrappers/saxlibxml2.o] Error 1


That doesn't sound good?!

Thanks again,

Re: gcc v3.4.4; templates and compile errors

[corey taylor]

It looks like you're missing a "typename" keyword on that line.

The reason int works is because that removes the dependency from the
template parameters.

typename SAX::basic_XMLReader<stringT>::Property<typename
SAX::basic_DeclHandler<stringT> *>* prop;

More information on this whole requirement is under the C++ section
of: http://gcc.gnu.org/gcc-3.4/changes.html

gcc v3.4.4; templates and compile errors

[Magyar, Thomas J. CIV NAVAIR]

In upgrading from gcc v3.3 to gcc v3.4.4 on an SGI IRIX 6.5, I'm having a compile error that I can not figure out. We're trying to build the SAX library, and in one of the files (saxlibxml2.h) there is a function that a line is giving me an error:

template<class stringT, class string_adapterT>
std::auto_ptr<typename basic_XMLReader<stringT>::PropertyBase> libxml2_wrapper<stringT, string_adapterT>::doGetProperty(const stringT& name)
{
  if(name == properties_.declHandler)
  {
-->    SAX::basic_XMLReader<stringT>::Property<SAX::basic_DeclHandler<stringT> *>* prop;

    prop = new SAX::basic_XMLReader<stringT>::Property<SAX::basic_DeclHandler<stringT>*>(declHandler_);

    return std::auto_ptr<typename SAX::basic_XMLReader<stringT>::PropertyBase>(prop);
  }

  ...
}

The line beginning with SAX:: is giving us this compile error:

SAX/wrappers/saxlibxml2.h:310: error: expected primary-expression before '*' token


Not very helpful really. In playing around with the line of code and trying to narrow it down, I have found out that if I replace all the '<stringT>' in that line (there are 4 instances of it) with '<int>' it compiles without warning. But obviously, it won't work as intended. So it is something to do with the 'stringT'. Yet there are other functions in this file that use stringT and with no compile errors. 

Does anyone who is good with templates have any ideas in what I may be missing? I'm only familiar with basic templates...this code is what I call template hell!

Thanks,

Tom
