hi,

when i m trying to use libgpp-types like String, strstream i always
get the same linker errors - it looks like this (message):
/*

There were some errors
*/
i dont understand these errors, because i lokked into the libgpp.a and
found string.o with the above listed references. i also tried using
gxx (resp. g++) instead of gcc, but problems stay.

i downloaded ver 2.80 from ftp.univie.ac.at (simtel-mirror) by first
using delories zip picker and rhide1.4. my systeme is running on dos.
am i missing any libraries (i also tried listing the gpp explicitly in
the libraries-dialog)?
if you have any idea, i d be really happy....
