Hi all,
I got the problem that I can't catch an exception which is thrown in a
shared library under MS windows. Since we need to use exceptions to tell
the calling site if something went wrong, we need a working exception
mechanism.
The compilers I tried were g++-4.1.2 and g++-4.2.2, running unter cygwin
with mingw32 target. The compilers where generated from vanilla sources,
configure paramters are ../gcc-4.2.2/configure --host=i686-pc-cygwin
--build=i686-pc-cygwin --target=i586-pc-mingw32 --enable-languages=c,c++
So does anyone know how to enable the exception handling mechanism so it
works under windows?
bye
Rudi
