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
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).
Thanks
Allan
(Yes, I am reading the notes at cygnus, and am looking into
