RE: Using std::basic_string<int> results in link error

I had the same thing -- a kind gentleman named Mathieu Fluhr
<mfluhr@nero.com> sent me a modified version of char_traits.h, which I
simply dropped into gcc-home-directory/include/c++/3.x/bits/ and
replaced the old one with his modified one.  Fixed all my problems.

I don't know if I'm allowed to give the file to you but I'm sure if you
ask him he will send it to you.  They say it's been fixed in libstdc++ 6
which comes with gcc 3.4, but I haven't verified this.  I have to stick
with gcc 3.2.3 for now.

Subject: Using std::basic_string<int> results in link error


The cause of this problem seems to be rooted in the fact that templates
are in libstdc++ instead of being compiled when using the STL. Is there
a parameter that can be passed to g++ to tell it to compile the STL
templates on the fly instead of using the precompiled ones?

Using std::basic_string<int> results in link error

[Jean-Francois Im]

Hi,

I am porting a program to GNU/Linux which uses the ICU library. Parts
of this code uses the std::basic_string<> template with the UChar32
type from ICU (http://oss.software.ibm.com/icu/apiref/umachine_8h.html#a35).
However, this results in errors at link time.

For example, this simple program does not compile(if it does, change
int to long or float or another non-char and non-wchar_t type) :

#include <string>

int main() {
       std::basic_string<int> foo;
       foo+=(int)'a';
       return 0;
}

The cause of this problem seems to be rooted in the fact that
templates are in libstdc++ instead of being compiled when using the
STL. Is there a parameter that can be passed to g++ to tell it to
compile the STL templates on the fly instead of using the precompiled
ones?
