gcc 3.1.x and std::basic_string< xxx >::replace( xxx ) link errors - please help

["Dylan Cuthbert" <dylan at q-games dot com>]

Hi there,

I have downloaded the very latest 3.11 version of gcc for cygwin.
I have also tried compiling my own version of gcc 3.1.x.

This version - "g++ (GCC) 3.1 20020325 (prerelease) " does *not* give the
link error I'm about to describe:

The current gcc version I am using is:

--- snip ----

 $ g++ -v
Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/3.1.1/specs

Thread model: posix
gcc version 3.1.1 20020710 (prerelease)

---- snip ----

With any long and complicated piece of code using strings I get this error
(and sometimes others from other functions in stdlib).

 undefined reference to `
std::basic_string<char, std::char_traits<char>, std::allocator<char>
>::replace(std::__normal_iterator<char*, std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >,
std::__normal_iterator<char*, std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >, unsigned, char)'
collect2: ld returned 1 exit status

This might be related to the #pragma interface/implementation stuff as we
also tried to use these (we aren't anymore) and got spurious link errors
from symbols in .cpp files that were simply including header files with the
#pragma interface command in them.  I just happened to notice that
"basic_string.tcc" etc. use a similar #pragma.

The things I have tried so far:

I "hacked" the basic_string.tcc file and placed junk in the replace command
above to make sure the file was being compiled - it reported the error
correctly.

2. I #if 0'd the entire basic_string.tcc file and block copied its contents
(minus #pragma and other stuff ) into my own code - it complained about more
symbols being missing (on top of the replace).

Does anyone have any ideas where to even start?

Regards
