Hi All,
This isn’t an Xcode questions per se,
but I was wondering if anyone has seen the below problem. I also posted to
gcc-help and libstdc++ lists, but no responses. Thanks!
I recently updated my system from gcc 3.3. to 4.0
(Panther to Tiger), and now I am getting a template error. For the below
code, I get the “error: no member function assign declared in
std:::char_traits<myChar>”.
typedef std::char_traits<myChar> myTraits; //
Interestingly, if I change this to
__gnu_cxx::char_traits
// then it compiles, but I’m not sure if this is
correct/acceptable
template <> void myTraits::assign(myChar& lhs,
myChar const& rhs)
{
// definition
}
I looked in char_traits.h and saw that there is a
new namepsace __gnu_cxx, with a base struct of the same name as the derived
struct in std namespace. I also came across an libstdc++ archived posting
about __gnu_cxx’s char_traits masking the one in std, not sure if this is
related to the error I’m getting. Does changing the typedef to
__gnu_cxx::char_traits effectivlely achieve what the previous line of code
(std::char_traits) was doing? Thanks for your help.
- Alex
