I have the same problem. Win 10, Python 2.7.10 and have VCForPython27 installed.

@hungrh That is a problem caused by MS C compiler not supporting C99. Source code of one of yowsup's dependences (python-axolotl-curve25519), uses variable definitions mixed with code, a feature introduced in C99 (in C89, variables should be defined at the begginning of the scope). To get rid of this problem without modifying that module's code, I will tell you what worked for me:

1.- Install Python 2.7.9 for Windows x32. I do not know if it works with Python 3 or the x64 versions, just know that it works well with 2.7.9 and that it does NOT work with 2.7.10.

2.- Download and install MinGW from http://sourceforge.net/projects/mingw/files/ (Select Installer, download the mingw-get setup package and follow instructions to install MinGW with MSYS and C compiler). We need it as the gcc included with MinGW supports C99.

3.- Navigate to C:\Python27\Lib\distutils (providing you installed Python in C:\Python27) and create a plain text file called distutils.cfg with the following content (two lines):

[build]
compiler=mingw32

4.- Download zlib for MinGW32 from http://sourceforge.net/projects/mingw/files/MinGW/Extension/zlib/zlib-1.2.7-1/ (pick the dev version) and copy the files to include and lib directories in your MinGW installation.

5.- Now go to your yowsup folder and attempt python setup.py install again, it should complete without problems.

Thank you @antonio9213 ! Looks like your text is worth updating README.md

Still getting the error regarding the axolotl curve25519. Can you help me resolving the issue?
