[question] What's the replacement of `virtualenv` generator in Conan 2?

[PauloCarvalhoRJ]

Hello,

So, I have in an Conan 1 recipe:

    generators = "cmake", "virtualenv"

How do I rewrite this in order to get the activate.bat script in Conan 2? Is it the VirtualRunEnv? I don't want to get fooled by a possibly misleading namesake.

best,

Hi @PauloCarvalhoRJ thanks for your question.

Yes, the virtualenv generator was replaced with the VirtualRunEnv and VirtualBuildEnv generators. Those are available in Conan 1 too, and their usage is pretty similar, as described in their documentation sections

In fact, these 2 generators are injected by Conan 2 by default, so if you don't need to customize anything, you can drop them from the generators expression too :)

Let me know if this helps, we're always happy to help in the transition from Conan 1 to Conan 2!

Hello,

Thank you for the feedback. Continuing on the issue, I have a legacy Bootstrap.cmake script that expects a Conan 1-generated conanbuildinfo.cmake. What is the new name of the corresponding file in Conan 2? I found several .cmake files in the build directory, but I couldn't identify which one would do.

regards,

In Conan 2 (and also using the CMakeDeps and CMakeToolchain integrations in Conan 1), the integration is transparent. No need to modify the CMakeLists.txt to include anything Conan-specific. Just standard find_package().

Check for example how it works:

mkdir dep && cd dep
conan new cmake_lib -d name=dep -d version=0.1
conan create
cd ..
mkdir pkg && cd pkg
conan new cmake_exe -d name=pkg -d version=0.1 -d requires=dep/0.1
conan build

The pkg uses the CMakeToolchain and CMakeDeps, inspect the CMakeLists.txt to see how it works.

Also, the tutorial, in the first section explains about this, see: https://docs.conan.io/2/tutorial/consuming_packages/build_simple_cmake_project.html
