Need help HP aC++ Version 6.* compiler

[nayeem khan]

Hi

I am porting a product to aC++ version 6 compiler
currently we are using version 5

Old C++ Version =aCC: HP aC++/ANSI C B3910B A.05.52 [Sep 05 2003]

Current C++ Version = aCC: HP aC++/ANSI C B3910B A.06.06 [Nov 7 2005]

However in one of the module i am facing some errors,the error message is


"../../mdds/threadsafestl/iterator.h", line 39: error #2266: "input_iterator_tag
" is ambiguous
inline input_iterator_tag"

It compiles fine with version 5 compiler. I think in new version has come enhancement due to which i am getting this error.

I unserstand that compiler found two versions of "input_iterator_tag".

Can someone give me a hint ,how to solve this issue

Unfortunately without more of the error message or the whole instantiation trace back, it is kind of hard to determine what's wrong.

I don't see Error 2266 on our aCC5 to aCC6 page:
http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,7274,00.html

This could be related to my answer in:

It would help if you could provide more of line 39 and 40 to any "{" or ";".

Does the compiler tell you where the other input_iterator_tag is declared, so you can also show that?

You may have to compile with -E -.i to create a .i file any provide that, if you don't have any IP concerns.

I have attached the error file from version 6 compiler and warning from version 5 compiler

If i compile the same file with same options but with Version 5 compiler it compiles fine(ofcourse with warnings)

We are using a threadsafe STL,where its failing in iterator.h
below is the code,its failing at
"inline input_iterator_tag "
------------------code----------------
template
inline input_iterator_tag
iterator_category(const input_iterator&) {
return input_iterator_tag();
}
--------------------code----------------

>I have attached the error file from version 6 compiler and ...

I only see the useless aCC5 warnings.
Warning 890: warning is being replaced by followed by "using namespace std;"

This may cause there to be two input_iterator_tag. One in std and one in the global namespace.

>We are using a threadsafe STL,

Why do you think you need this alternate STL?
Just compile with -AA -mt.

If you don't use HP's Standard C++ Library, you must compile with +nostl.

>+nommap +inst_v +eh -DRW_MULTI_THREAD

Remove +nommap. +inst_v doesn't work on IPF.
Remove +eh, since it is the default.
-DRW_MULTI_THREAD is not valid with -AA.
(Use -mt for threading.)

>where its failing in iterator.h
template
inline input_iterator_tag
iterator_category(const input_iterator&) {
return input_iterator_tag();
}

I doubt I can figure out anything without a .i file.

I recently had to change to remove all of the __iterator_category functions and replace by one:
template
inline _TYPENAME iterator_traits<_Iterator>::iterator_category
__iterator_category(const _Iterator&) {
typedef _TYPENAME iterator_traits<_Iterator>::iterator_category _IterCategory;
return _IterCategory();
}
