installing ddd

[Hyondeuk . Kim]

Hello, I have a problem installing ddd.
I get this error when I do ./configure

configure: error: You must set the environment variable CXX to a working
                  C++ compiler.  Also check the CXXFLAGS settings.
                  See the file 'config.log' for further diagnostics.

I tried
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure

and get the same error.

I also tried

CXX=/usr/egcs/bin/g++ CC=c89 CFLAGS=-02 LIBS=-lposix ./configure

and got this error.

checking for C compiler default output file name... configure: error: C compiler
cannot create executables
See `config.log' for more details.

Please tell me what I need to do. Thank you.
