Re: Embarassing question on linking

Now under hello.c, I have no errors,  I'm guessing that I need to do something to link the correct libraries which are needed under (G)C++, and were included by default under GCC (ansi).
----

1. use g++ instead of gcc

2. use void if the function does not return anything. ( the default return type is int if not specified)

The following is the similar code compiled and run in my Windows 95:

//g/tmp/tmp ) cat hello.cpp
#include <iostream.h>
 
void main()
{
cout << "Hello there GNU++ world!" << endl;
}
//g/tmp/tmp ) g++ -o hello.exe hello.cpp
//g/tmp/tmp ) hello
Hello there GNU++ world!
 

Sincerely,
Wei Ku

Subject: Embarassing question on linking

I am learning C++ using cygwin32, so I am not too well versed in these
unix type utilities (previous experience with IDE based products).

I'll cut to the chase..  hello world based C++ program yields the
following:

The code:

bash$ cat hellopp.cc
#include <iostream.h>

main()
{
        cout << "Hello there GNU++ world!\n";
}
bash$

The error:

bash$ make -f hellopp.mak
/gnuwin32/b18/H-i386-cygwin32/bin/gcc.exe -pedantic -o hellopp.exe
hellopp.cc
C:\TEMP\cc0010051.o(.text+0x2a):hellopp.cc: undefined reference to
`cout'
C:\TEMP\cc0010051.o(.text+0x2f):hellopp.cc: undefined reference to
`ostream::ope
rator<<(char const *)'
gcc.exe: Internal compiler error: program ld got fatal signal 1
make: *** [hellopp.exe] Error 1


Thanks
