undefined reference to ___assert, _impure_ptr, etc.

[Brian Warner]

Hi,

I'm using Cygwin for compiling the Xerces-C library for MinGW. My program 
used the gcc 3.2, and there were no problem, but now I use the gcc 3.2.2 for 
my program, so I need to recompile the Xerces-X library too. But the gcc 
3.2.2 doesn't exist for Cygwin, so I compiled it with the source on Cygwin, 
with the options --enable-threads=posix --enable-shared 
--enable-languages=c,c++. The compilation seems to be passed very well, but 
now when I want to compile the Xerces-C library, at link time, I've got 
several undefined reference errors such as ___assert, _impure_ptr, 
___w32_sharedptr_unexpected, etc. Many of these error are related with 
libstdc++.a. And when I look in this file, I see the reference to these 
functions. So where can this problem come from ? Is my gcc 3.2.2 badly 
compiled ? I've seen there is a gcc-mingw, and its configure file is very 
different from "normal" gcc configure file. Have I to compile it with a 
configure file from the gcc-mingw version ?
Thanks in advance.

Regards,
Fabrice Louis.
