Error while build triangle from source: c1: fatal error C1083: Cannot open source file: 'c/triangle.c': No such file or directory

Question

I am getting this error while trying to build triangle (The source file can be accessed from here: https://github.com/drufat/triangle) from source:

` c1: fatal error C1083: Cannot open source file: 'c/triangle.c': No such file or directory error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.37.32822\bin\HostX86\x64\cl.exe' failed with exit code 2

` I am using Windows 11, anaconda 3, python 3.9.17 I tried installing different versions of microsoft build tools but I get the same error every time. I even tried on a different machine with different version of anaconda and python, but still im getting the same error. Can somebody help me in fixing this issue?

The error states `'c/triangle.c': No such file or directory error` is there such a file? What steps have you performed for the installation? — FlyingTeller, Aug 18 '23 at 08:11
Just some wild guess... Is `c/triangle.c` part of a longer filename with a path containing space right before the `c/`? Don't do this. — Gerhardh, Aug 18 '23 at 08:29
Yeah i followed this procedure https://rufat.be/triangle/installing.html of building from source but still the same error. And i cannot see c/triangle.c any of such file — Mohsin Bashir, Aug 18 '23 at 08:32
@Gerhardh im not sure what c/triangle.c is. Also i did not see it anywhere in source code. — Mohsin Bashir, Aug 18 '23 at 08:40
@MohsinBashir HI Mohsin, have you checked Jeremy's answer, does it work for you? :) — Bowman Zhu-MSFT, Aug 21 '23 at 05:44

If you look at GitHub, you'll see there is a c directory but it looks like this:

c @ 8b9e104

This means it is a submodule. You need to do extra steps to pull it down. If you clone the repo, you need to go into it and then execute the following two commands

git submodule init
git submodule update

See the following (done on a Mac but the idea is the same)

jeremyp@mymachine dev % git clone https://github.com/drufat/triangle.git
