I have this source code from 2001 that I would like to compile.
It gives this:
$ make
g++ -O99 -Wall -DLINUX -pedantic -c -o audio.o audio.cpp
In file included from audio.cpp:7:

make: *** [audio.o] Error 1
audio.h contains
#include <stdlib.h>
#include "mad.h"
namespace audio {
class stream {
private:
char* Buffer;
size_t BufferSize, BufferPos;
struct mad_decoder Decoder;
friend enum mad_flow input(void* Data, struct mad_stream* MadStream);
friend enum mad_flow output(void* Data, const struct mad_header* Header,
struct mad_pcm* PCM);
friend enum mad_flow error(void* Data, struct mad_stream* MadStream,
struct mad_frame* Frame);
public:
stream(const char* FileName);
~stream();
void play();
};
}
I have tried to just insert
enum mad_flow {};
but that just gave a new problem.
Can anyone see how to fix this?
