Hallo Alex,

If you use g++ to link, libstdc++ will be linked in automatically,
that was the reason why I wrote:
gcc -o your.exe your.o -L/your/path -lstlport

> $ g++ -o foo_orig.exe foo.o

If you use gcc here as well then you'll need top specify -lstdc++ at
the linkline.

> Is foo_port.exe really STLported?

No, obviously not.  Cygcheck should show stlpot as dependency.  There
are some useful switches for the compiler / linker.  You can specify
the include directory to be used during compilation with:

-I/path/to/stlport-headers

and the path to the libraries you want to link with:

-L/usr/lib/stlport

Usually there is no need to move the libraries around.
