Problems with template instantiation in C++
I use the the g++ 4.3.2 compiler on my linux machine. If I compile the following piece of code I get a bunch of compiler time error. In my opinion the compiler
have all information to process the code properly. I can't imagine, what's going wrong? Sorry for the long code portion, but I have reduced the code as much as possible! You can view the source code and additionally the compiler error message! Code:

The first several lines about the "export" keyword should be pretty clear: "export", used to enable a separation of declaration and definition of template classes/functions, is not supported by GCC.
A common work around to avoid this deprecated keyword and still stay on top of things is to do sort of a reverse include: Provide prototypes (with normal header extension) and definitions (usually with an "impl" ext.) in distinct files as usual but include the implementation file at the end of the header file. This is necessary as template instantiation requires presence of definition so it can instantiate the template "in one go". Another error I spotted at a quick glance is linked with the very last function. Am I right in assuming it should be a total specialization of the function above? Then it should read "template <>". Of course, also here the function's definition is missing. Hth, Gunther |

I thank you for your help.

I have shorten the code to publish it on this forum. In the real world this file is scattered over several files. The core module of this project is about 20000 lines. Every additional module can be rough about 100 000 lines or the multiple size. Therefore I concluded to separate the compile units. Quote:

Dear Gunther,
I have changed my code to Code:
export template <class Ch, class Tr, class In, class Ef, typename SgF>
basic_istream<Ch, Tr> &dataScanStatus(
basic_istream<Ch, Tr> &is,
Ef &un_format, bool mandatory, SgF status) {
ios_base::iostate state = ios_base::goodbit; // good
In eos;
(use_facet<Edifact_get<Ch, Tr, In> >(is.getloc()).*status)
(is, eos, is, state, un_format, mandatory);
return is;
}
template istream &dataScanStatus<char, char_traits<char>,
istreambuf_iterator<char, char_traits<char> >, ElementFormat,
Typedefines<char>::SetGetElementFormat>(
istream &is, ElementFormat &un_format,
bool mandatory, istreambuf_iterator<char, char_traits<char> >
(Edifact_get<char>::*sgef)(
istreambuf_iterator<char, char_traits<char> > begin,
istreambuf_iterator<char, char_traits<char> > end,
basic_ios<char> &s, ios_base::iostate &r,
ElementFormat &token, bool mandatory));
export template <class Ch, class Tr, class In>
basic_istream<Ch, Tr> &begin_of_element(
basic_istream<Ch, Tr> &is, ElementFormat &un_element,
bool mandatory) {
return dataScanStatus(is, un_element, mandatory,
&Edifact_get<Ch, Tr, In>::begin_of_element);
}
template istream &begin_of_element<char, char_traits<char>,
istreambuf_iterator<char, char_traits<char> > >(
istream &is, ElementFormat &un_element,
bool mandatory);
begin_of_element(..). But the g++ compiler throws the errors Code:
xing.class.cc:313: instantiated from here xing.class.cc:307: error: no matching function for call to ‘dataScanStatus(std::basic_istream<char, std::char_traits<char> >&, Edifact::ElementFormat&, bool&, std::istreambuf_iterator<char, std::char_traits<char> > (Edifact::Edifact_get<char, std::char_traits<char>, std::istreambuf_iterator<char, std::char_traits<char> > >::*)(std::istreambuf_iterator<char, std::char_traits<char> >, std::istreambuf_iterator<char, std::char_traits<char> >, std::basic_ios<char, std::char_traits<char> >&, std::_Ios_Iostate&, Edifact::ElementFormat&, bool))’ Code:

Another problem of the introducing code is the following error: Code:
xing.class.cc: In function ‘std::basic_istream<_CharT, _Traits>& Edifact::control(std::basic_istream<_CharT, _Traits>&, In (Edifact::Edifact_get<Ch, Tr, In>::*)(In, In, std::basic_ios<_CharT, _Traits>&, std::_Ios_Iostate&)) [with Ch = char, Tr = std::char_traits<char>, In = std::istreambuf_iterator<char, std::char_traits<char> >]’: xing.class.cc:282: instantiated from here xing.class.cc:271: error: invalid conversion from ‘const Edifact::Edifact_get<char, std::char_traits<char>, std::istreambuf_iterator<char, std::char_traits<char> > >*’ to ‘Edifact::Edifact_get<char, std::char_traits<char>, std::istreambuf_iterator<char, std::char_traits<char> > >*’ I cannot image, what is wrong?

Maybe you could mark which lines of your code excerpt are the relevant ones.
Btw, where's the function body of your template specialization for "dataScanStatus"? PS: I also suggest using gstlfilt. It will also shorten your error messages. |
