Hi,
This is a small test case I wrote in which I can't understand why I have an
undefined reference. I have an undefined reference which I thought only
requires linking w/ the libs that contain this symbol, which I am. The
function dm_connect() is in the library libdm, and this is on the g++
command line when I compile as shown. The libdm is a C library and I'm
calling this in my C++ program.
Can anyone help me understand what I'm doing wrong?
--- Compile and Error
$ g++ $(pkg-config --cflags glib-2.0) -I/usr/include -I/usr/local/include
-I/home/joe/Projects/net-1.0/util -L/usr/local/lib

int fd = -1;
uint16_t port = 11002;
char *dmhostname = "localhost";
fd = dm_connect(dmhostname, port);
if (fd < 0) {
printf("failed\n");
}
return 0;
}
