Hey there! Let's sort out your SDL2 installation issue with Conan. Here's what's happening and how to fix it:

Why the Error Happens #

The SDL2 package you found (SDL2/2.0.5@dotfloat/stable) is outdated and incompatible with modern Conan versions. The ConfigureEnvironment module it tries to import was part of early Conan 1.x releases and has since been removed. This means the package itself is effectively broken for current Conan setups—so it's not your operation that's wrong, it's the package's age.

Correct Way to Find & Install SDL2 with Conan #

Forget that old bintray package. Instead, use the officially maintained SDL2 packages in Conan Center (Conan's official, up-to-date package repository). Here's how to do it properly:

1. Using conanfile.txt #

First, create or update your conanfile.txt with a valid, maintained SDL2 version:

[requires]
sdl2/2.26.5  # Pick any stable version you need—2.0.x branches are also available in Conan Center
[generators]
cmake

Then run the install command from your project directory:

conan install . --build=missing

The --build=missing flag tells Conan to compile the package from source if pre-built binaries aren't available for your system.

2. Using Command-Line Installation #

If you prefer installing directly via command line, run:

conan install sdl2/2.26.5@ --build=missing

If you need to target a specific build configuration (like debug/release, or a specific compiler), add profile flags, e.g.:

conan install sdl2/2.26.5@ --profile:build=default --profile:host=my_custom_profile --build=missing

Extra Tips #

• Update Conan: Make sure you're on the latest stable Conan version. Check with conan --version, and update if needed with pip install --upgrade conan.
• Search for Packages Properly: Use Conan's built-in search to find valid packages in the official repository:

  conan search sdl2 --remote=conancenter
  

  This will show you all available SDL2 versions and their details.
