Re: Error installing Python Extension on Windows 10 - SaxonHEC1.2.1

Thanks, O'Neil.

Yes, I'm aware of that question and the idea of installing Windows 10 SDK. I tried most of the methods there and was hoping to avoid installing the SDK. I'll do that if there's no other solution.

FYI, I also ran into another solution - open the Administrator Developer Command Prompt for VS 2017 (never heard of it, nor knew it was installed on my machine...) and make sure you do that as administrator (!) and run "saxon-setup.py build_ext -if " inside that.  Doing that got me past the  "Cannot open include file: 'io.h': No such file or directory" stage (it's something, at least...) but smack into another error message:

fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'x86'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\BuildTools\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x86\\link.exe' failed with exit status 1112

I'm still try to research that one; seems even worse than the "missing" io.h" error.

Maybe you guys should consider just releasing a virtual machine image  (an Ubuntu guest for example) with the most recent Python and Saxon HE versions pre-installed...

Hi,

This error message is a new one for me. Not seen it before. Have  you tried installing Windows 10 SDK?

As you mentioned this problem many do experience. You might find a resolution to your problem on the stack overflow link below:

On running
saxon-setup.py build_ext -if

(Windows 10, 64 bit using Powershell as administrator)

I get this error message:

fatal error C1083: Cannot open include file: 'io.h': No such file or directory
error: command 'C:\\Program Files (x86)\\Microsoft<file://Microsoft> Visual Studio\\2017\\BuildTools\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

io.h is installed, in several places, actually; on of which is in PATH variable, and another one in the same directory as cl.exe.

I understand the disappearance of io.h is a fairly common occurrence, but all my research did help me resolve it.

Any help would be appreciated.
