The package cannot be compiling

[WHULMQ]

I try to compiling the package today.But there are some errors as:

error: failed to run custom build command for gdal-sys v0.3.1

Caused by: process didn't exit successfully: D:\VScode\rust\read_tif\target\debug\build\gdal-sys-21e0a3b3239f1c3a\build-script-build (exit code: 101) --- stdout cargo:rerun-if-env-changed=GDAL_STATIC cargo:rerun-if-env-changed=GDAL_DYNAMIC cargo:rerun-if-env-changed=GDAL_INCLUDE_DIR cargo:rerun-if-env-changed=GDAL_LIB_DIR cargo:rerun-if-env-changed=GDAL_HOME cargo:rerun-if-env-changed=GDAL_VERSION

Did you try to download GDAL and set those environment variables (at least GDAL_HOME and/or GDAL_INCLUDE_DIR and GDAL_LIB_DIR)? ~~Windows binaries are a bit hard to find, but https://www.gisinternals.com/release.php should be fine. Make sure to download the one that matches your C compiler.~~ Looks like you might need a MinGW version instead.

How can I set those environment variables? I did not download GDAL. I just add ' gdal = "0.7.2" ' in Cargo.toml .

Cargo.toml: [dependencies] gdal = "0.7.2"

You need to either compile or install/download a GDAL version compiled with MinGW (it might be easier to install VS Community, switch to the stable-msvc Rust toolchain, then download a MSVC GDAL), then you can set the environment variables like:

SET GDAL_HOME=D:\gdal
SET GDAL_INCLUDE_DIR=D:\gdal\include
SET GDAL_LIB_DIR=D:\gdal\lib

or similar.

After we upgraded to the latest from 0.6, we found that $env:GDAL_VERSION must be set or the gdal-sys build script will just quit (Windows)

it would be great if we could add a solution to the readme

may i ask how to do that and the version is the windowns gdal version like "3.8.4" or the toml denpandenice version like "0.16.0"
