Hi All I have dicovered, that on Cygwin at least, mapserver builds with gcc 3.2 by either 1) including -lstdc++ in the link libs STATIC_LIBS= $(GD_STATIC) $(OGR_STATIC) -lstdc++ or 2) linking with c++ instead of gcc executable: dependencies $(CXX) .... ..... This of course requires that gdal is also built with c++3.2 The resulting executables seem to run fine :-) Cheers Norman
