Installation is being failed

[Bondopadhyay]

For Windows, does one need to rewrite the make file?

This is my first time installing and using tippercanoe. My objective is to convert vector data into PMTiles. However, that is secondary.

It failed to build trippercane. I simply ran pip to install tippecanoe.

After the successful preparation of metadata, it was bouncing with errors.

Output:

Assist, please.
If something is amiss on my end, let me know.

The Python pip script for tippecanoe is not something I created, so I don't know what it does. I am also not a Windows user, so I don't know what might need to be different in the Makefile for Windows. Tippecanoe does not use cmake, so you appear to be running a different Makefile than the one supplied with Tippecanoe.

The intent of the Makefile is that you should be able to do:

git clone https://github.com/felt/tippecanoe.git
cd tippecanoe
make

to get a working copy of Tippecanoe. Try that, and if it doesn't work, tell me what happens and I will try to figure out what is wrong.

There isn't a pre-built binary wheel on PyPI for Windows, so pip falls back to trying to build from the source wheel (the CMake build script is just running make on tippecanoe's default makefile). If tippecanoe supports building under MinGW using its current Makefile then I can get a pre-compiled binary wheel for Windows added.

For native builds using MSVC (instead of MinGW) from source on Windows, that would likely require tippecanoe to start using CMake.

I have a draft PR with the changes needed to build tippecanoe using MinGW without compiler errors, however it very likely crashes when you try to run the resulting executable: #293
