In Redhat 9.0, I have installed and compiled ICE-1.5.1 successfully. All demos worked fine! Last days, I tried to design a simple test program. At the basis of "hello, world!" code, I inserted a single line:
#include <Ice/Ice.h>
When I compiled this program, it gave the following output:

g++ -DHAVE_CONFIG_H -I. -I. -I.. -I/opt/Ice-1.5.1/include/ -Wall -g -c -o main.o `test -f 'main.cc' || echo './'`main.cc

What's wrong with me?
