[bug] Conan generator results are not overwritten on a second run #16274

oweissbarth · 2024-05-16T10:27:38Z

Describe the bug

Linux, Ubuntu 22.04, Conan 2.2.3, Python 3.10.12

How to reproduce it

When re-running the install command a second time with different requirements at a later point the conan generator results are not updated.

Run the following commands:

conan install -g CMakeDeps --requires="poco/1.9.4"
conan install -g CMakeDeps --requires="poco/1.13.3"

Afterwards I would expect PocoConfig.cmake to contain information about poco/1.13.3 instead it still contains information about poco/1.9.4.

In PocoConfig.cmake:

[..]
set(Poco_VERSION_STRING "1.9.4")
[..]

See full log below.

Hi @oweissbarth

Thanks very much for your detailed report.

It is true that Conan was doing something unexpected there, caching the previously existing xxxxConfig.cmake file to preserve previous variable definitions. It is not fully clear why it was there, I am trying to remove it in a draft PR #16279 and see if something break, and understand potential issues.

memsharded · 2024-05-28T16:07:53Z

#16279 was merged, it will be in next Conan 2.4, thanks again!
