    Can anyone get this to build in windows?


    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.

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

    It sounds like it is not currently made to build on Windows, so you're essentially asking someone here to do the port for you, and that is likely to be a lot of work.
    Post some of the specific error messages and see if others can guide you through those instead.

    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.

    The errors about multiply defined functions probably mean those functions are implemented in a header file, which is included in multiple source files. Move the function definitions out of the header file(s), into a single source file.

    The undefined references mean that some needed code (in compiled form in a library or an object file) is not being supplied to the linker. You need to find the library files, and ensure they are specified in the link. Bear in mind that the order of files specified when linking is often important, particularly when libraries are included in the link.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.

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

    .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.

    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.)

    #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.

    .objs\RtMidi.o:RtMidi.cpp:(.text+0x174): undefined reference to `vtable for RtMidiIn'

    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.

    In order to see what's going on, it's probably easiest to make C::B spit out the entire command line. (Under settings->Compiler and debugger->Other settings, and set Compiler logging to full.)

    In that case you should see a bunch of compiling of source code (actually this time you won't, since they are already compiled), and then at the end the linker. You want the linker command to end with "-lwinmm" (with a lowercase L). If it doesn't then that's what you need to fix.

    EDIT: Also looking at that link, you may want to define __WINDOWS_MM__, as it looks like that may enable the Windows-specific parts of the code. Easiest is to do it as they show for the other OSes, by putting -D__WINDOWS_MM__ as a compiler option. You'd have to recompile everything (Ctrl-F11).

    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?
