Build failed on Win 10 64bit: ninja: fatal: CreateProcess: The system cannot find the file specified.

[Ben-Mack]

I'm following this guide to build Ion to use with Seurat: https://github.com/googlevr/seurat/blob/master/BUILDING.md

Build on Windows:
c:\Seurat>git clone https://github.com/google/Ion third_party\ion
c:\Seurat>cd third_party\ion
c:\Seurat\third_party\ion>git submodule init
c:\Seurat\third_party\ion>git submodule update
c:\Seurat\third_party\ion>ion\build.bat -c opt_x64

I'm trying to build on Win 10 64bit but failed at step run build.bat.

> C:\Users\Ben\Desktop\seurat\third_party\ion
ion\build.bat -c opt_x64

python.exe -u C:\Users\Ben\Desktop\seurat\third_party\ion\ion\\build.py -c opt_x64
ERROR: Could not determine what you want to build. Try specifying a gyp file or directory containing one.

Then I tried to cd to seurat\third_party\ion\ion and rerun:

@Ben-Mack I believe the file it can't find is cl.exe. I was able to produce a precompiled version of Seurat on my fork.

I was able to fix this particular issue by opening the Visual Studio 2017 Developer console (which has all the msvc tools in its path).

I didn't go through the lengths of using Visual Studio 2015, but solving this specific issue was only the tip of the iceberg for me. I had to manually edit ~2-3 Ion source files and ~4-5 gyp/configuration files to get Ion to compile nicely on Windows 10/VS2017.

Hi @Ben-Mack!

Are you running from a Visual Studio command prompt? Otherwise, you may need to run one of the VCVARS batch file variants before running the Ion build:

"c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_amd64
