: Note: it appears that gcc DID NOT 'link with the standard C++ library',
: although the cpp file extension appeared in the second command line.

: now I try it again with manual link option with library:
: gcc -O2 -g -Wall dxe2api.o dxe2stat.o -I../include dxe2gen.cpp -o
: dxe2gen.exe -lstdcxx

: ...and it works fine. it seems that GCC is not automaticly pulling up the
: standard C++ lib here, even when a .cpp file is being specified.

Well it looks like you didn't uninstall the previous version of gcc
before installing the one you're trying to use.


Right,
