it appears a one-character typo in the cmake_minimum_required line prevents it from compiling under CMake 4.0. in order to fix that, I had to take this thing out of submodules... it is recommended to do this after you pull; git submodule deinit extern/libsndfile

** ****************************
|
|
**
|
|
** How to use:
|
|
** - libsndfile.dll must have already been compiled and be in this
|
|
** application's search path
|
|
**
|
|
** - You must edit this file to point to the file you want to convert. Set
|
|
** the following line of code (found in the Main() function further below)
|
|
** to the name of a .WAV file that exists on your system.
|
|
** 186: string sfn = "input.wav";
|
|
**
|
|
** - From a command prompt type
|
|
** csc generate.cs
|
|
**
|
|
** - Run the resulting executable 'generate.exe'
|
|
**
|
|
**
|
|
** Note: You will obviously need the csc compiler and the .NET runtime. I think
|
|
** these are freely available for download from Microsoft's website
|
|
** (part of the .NET SDK?).
