Thread: Can anyone get this to build in windows?

Hi,

I found this program on the internet but I can't build it under windows. Here is the link: AwesomeBox | Open-Source Real-Time Pitch-Correction (is that enough hyphens for ya?) Can anyone get it to work? I am using Code::Blocks.

A couple of things I have already figured out:
It requires OpenGL
You have to convert usleep to sleep (and add the <windows.h> header for it to work)
You have to include <stdio.h> here and there for some functions.

I finally got it to compile but I am getting some linker errors.

Thanks

Well... as always, read the error messages and try to fix the problem.

Hi,

Thanks for the replies. This is the error message I am getting from the linker. I did modify the code so it would compile by adding some headers but I still get this.

Hi,

I fixed one of the errors. But it is showing an error for this one:

Code:

.objs\smbPitchShift.o:smbPitchShift.cpp:(.text+0x6b1): multiple definition of `smbFft(float*, long, long)'

I did a search for smbFft in the whole project it only showed four hits. All are in this one file. I don't understand why it is showing this. Sorry the code is so long.

Code:

#include <string.h>
#include <math.h>
#include <stdio.h>

#define M_PI_VAL 3.14159265358979323846
#define MAX_FRAME_LENGTH 8192

At a guess: is that file smbPitchShift.cpp, or is it a header file? (If it's the latter, you are entitled to go hit somebody, after you move the actual code into a .cpp file.)

Code:

#include "smbPitchShift.cpp" // Pitchshifter.cpp

There's your problem. While it's not technically a header, you are still entitled to go hit them.

That was my problem indeed. I just moved everything in smbPitchShift.cpp to Pitchshifter.cpp.

I fixed those errors. Now I just have the library errors.

Code:

.objs\RtMidi.o:RtMidi.cpp:(.text+0x174): undefined reference to `vtable for RtMidiIn'
.objs\RtMidi.o:RtMidi.cpp:(.text+0x1a2): undefined reference to `RtMidiIn::initialize(std::string const&)'

The program uses the RtMidi. It says in the help file to use the library winmm.lib. Here is the website: The RtMidi Tutorial

I tired adding the library to the linker options but it doesn't work. I really don't know anything about the linker. Do I need to added other things? Does anyone have any other advice?

Thanks so much, every one has been very helpful.

lol I finally got it to build after adding __WINDOWS_MM__ , __WINDOWS_DS__ , and __MINGW32__ to the #define section of the compiler. As soon as I ran it, it froze my computer for about a minute until I was able to kill it. At least it kind-of worked, it was repeating what I was saying in the microphone. I think I messed with the code too much. Now that I learned you have to define and link the libraries properly I will download the source again and try tomorrow.

Thanks for everyone's help, I will post back if I run into anymore problems.

So I downloaded the code again. I created a new project. I added some needed headers, fixed the problem where it would include .cpp files, added some defines for windows. I decided to start fresh because I messed with the code too much. Now I get "undefined reference to `CoUninitialize@0'" multiple times. I googled CoUninitialize and I found this. Should I add -lOle32 to the linker settings. On the RtAudio website it says nothing about CoUninitialize (This happens in RtAudio.cpp). It says under ApiNotes that you should use "-with-ds" I tired that but the compiler doesn't know what it means.

Here are my current linker settings. How do I know if they are out of order?

Code:

-lopengl32
-lglu32
-lglut32
-ldsound
-lwinmm

Thanks,
