Running Cython in Windows x64 - fatal error C1083: Cannot open include file: 'basetsd.h': No such file or directory

I have been trying to install Cython for Python 2.7 on my Window 7 system. In particular, I prefer everything in 64 bits. (In case you wonder, I need Cython because Cython is one of the components I need for another package for some specialized numerical analysis. And x64 is potentially an advantage for storage of large data sets.)

So I downloaded the x64 Python 2.7 from the official website. Got Cython from Christoph Gohlke. The amd64 version for Python 2.7 of course. Before I installed, I added Python 2.7 into the registry with the .reg file found in Joe DF's answer here. Afterwards, I installed the Visual C++ compiler from here (I don't think it works) and here (but this one should). At this point, I have in my C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin directory all of vcvars32.bat, vcvars64.bat, vcvars86_amd64.bat, vcvarsx86_ia64.bat. I ran vcvars64.bat and there was no error message.

Subsequently, I followed this page to create a "hello world" test file.

Then, I got this error.

...\Tests>python setup.py build_ext --inplace
running build_ext
building 'hello' extension
error: Unable to find vcvarsall.bat

So I thought to myself: Well, Cython can't find that file because it does not exist. (I searched my whole harddrive for it.) So I copied vcvars64.bat from ...\VC\bin to \VC and changed the name to vcvarsall.bat. Now vcvarsall error is gone. And ... naturally, a new error emerges.

...\Tests>python setup.py build_ext --inplace
running build_ext

e: 'basetsd.h': No such file or directory
error: command '"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64
\cl.exe"' failed with exit status 2

Now I have no idea how to proceed. What should I do? Your help is much appreciated.

(For clarity, I did try setting the compiler to Mingw32. But there are other errors. I am focusing on getting VC to work for now.)

EDIT: I tried using the SDK build environment CMD following the instructions on this page. I received the same error.

Solution 1:

In case anyone is currently (2017) facing same error with visual C++ 2015 tools, launch setup again and also select windows 8.1 / 10 SDK depending upon your OS. This will fix basestd.h error.

If it is still not working, try launching build tools from: C:\Program Files (x86)\Microsoft Visual C++ Build Tools.

Another alternative would be, just install anaconda 2 or 3 (64 bit if also you don't want memory errors). It contains all the important packages prebuilt: sklearn, matplotlib, scipy, numpy, pandas and even web development frameworks such as flask.

Solution 2:

I encountered this problem while trying to install pandas in 'develop' mode. I'm up & running now. My environment:

• Windows XP Pro x64 SP2
• WinPython 64bit 2.7.5.3 (Python 2.7.5.amd64) <-- "registered" as system's python distro using WinPython Control Panel application

Problems encountered when running python setup.py develop:

• Unable to find vcvarsall.bat
• fatal error C1083: Cannot open include file: 'basetsd.h': No such file or directory ... exit code 2

Solution:

1. Download and install Microsoft Visual C++ 2008 Express.
2. Download and install Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1. You will need only:
   • Developer Tools > Windows Headers and Libraries <-- this gives you basetsd.h
   • Developer Tools > Visual C++ Compilers <-- this gives you the 64-bit compilers
3. Copy C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars64.bat to C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\vcvarsamd64.bat. Observe the change in file name.
4. Add C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin to PATH. This may not be required (I did so before re-installing the SDK w/ Headers & Libs; therefore, the necessity is unknown).

At this point, running python setup.py develop completed successfully and python -c "import pandas; print pandas.__version__" resulted in the git tag I expected.

Solution 3:

For those with Windows 10, download the SDK from here to fix the header file basestd.h.

I downloaded the .exe, installed and worked great. SDK was ~2.3GB.

Note: For those like me with 64-bit systems who got an additional error:

`LINK : fatal error LNK1158: cannot run 'rc.exe'
    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1158

There is a great answer here which solves the problem by placing the rc.exe file in the correct folder for your system.

Solution 4:

Add these to the visual studio installation directories to your Environment variables

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools

hope it solves the issue.
