I downloaded the stl headers from rpmfind.net and
found a problem with it. The package name is:
hacklibstdc++-2.96-0.6mdk.i586.rpm and the problem was
in the <string> header. How ever did the
implementation, went ahead and commented out the
wstring definition. If you uncomment that line,
wstring will work as long as you are not calling
c_str() on it. The reason is that c_str() was
implemented with the following line:
return "". This means it will return a single wide
char when it really shoud return a wchar_t. However,
since the template is used for char and wchar_t, a
problem will be facing you to choose between return ""
or return L"".
Two ways to solve this. One to define an empty string
inside the implementation file
(/usr/include/g++-3/std/bastring.h) and it has to be
defined as char or wchar_t depending on the
instantiation.
The second solution (which I did) is to derive a class
from basic_string (I called the derived class
basic_wstring) and all I did is overridden the c_str()
function in basic_string. Then, in
/usr/include/g++-3/string, I modified the typedef
basic_string <wchar_t> wstring (which was commented
out) to typedef basic_wstring <wchar_t> wstring.
Everything started working out after that. I wonder
who will be taking care of this bug and when and where
would I get the new package?
Thanks
Abdul.
