Linking the binary using a class with user-defined type (template) V6.2 Up2
Hallo,
I am using the the following CC version:
CC: Sun WorkShop 6 update 2 C++ 5.3 Patch 111685-23 2005/10/14
We are porting some code to Solaris. I am using a template-based user type:
typedef vector<CMyClass *> CMyClassListType;
then a simple class
class CBatchClass
{
public:
....
private:
CMyClassListType Classes;
};
It's quite simple (there are just more similar cases). I can compile it but the linker prints some errors due to undefined symbols:
...
__rwstd::__rb_tree<std::basic_string><char,std::char_traits><cha r>,std::allocator<char> >,std::pair<const std::basic_string><char,std::char_traits><char>,std::allocator&l t;char> >,CThreadGroup*>,__rwstd::__select1st<std::pair><const std::basic_string><char,std::char_traits><char>,std::allocator&l t;char> >,CThreadGroup*>,std::basic_string<char,std::char_traits><char&g t;,std::allocator<char> > >,std::less<std::basic_string><char,std::char_traits><char> ;,std::allocator<char> > >,std::allocator<std::pair><const std::basic_string><char,std::char_traits><char>,std::allocator&l t;char> >,CThreadGroup*> > >::iterator __rwstd::__rb_tree<std::basic_string><char,std::char_traits><cha r>,std::allocator<char> >,std::pair<const std::basic_string><char,std::char_traits><char>,std::allocator&l t;char> >,CThreadGroup*>,__rwstd::__select1st<std::pair><const std::basic_string><char,std::char_traits><char>,std::allocator&l t;char> >,CThreadGroup*>,std::basic_string<char,std::char_traits><char&g t;,std::allocator<char>
...
I found that the probably cause is the C++ incompatibility of the standard STL implementation shipped with Sun Studio:

Hmm. Is that really the right reason? I've tried some tricks with "-instances" option but without success. How shall I correct this? The Sun people write:
>>You have to write explicit conversions in your source code as a workaround.<<
I've tried to rewrite the type definitions to
typedef vector<void *> CMyClassListType;
but even the native types are unresolved! Can anybody provide me with the information how to solve it without upgrading the Sun CC? Thank you very much.
Best regards
