[Bug] conan export-pkg has seemingly all values from profile propagated with the exception of CONAN_CMAKE_GENERATOR

[trondhe]

When I want to export to local cache from a local source dir, I first run the setup commands and build my project

conan install . -if=build -pr=myprofile
conan build . -sf=. -bf=build

then when I run either of these commands the wrong generator is used

conan export-pkg . user/channel -sf=. -bf=build -f
conan export-pkg . user/channel -sf=. -bf=build -pr=myprofile -f

Looking at the command variable at line 195 in the cmake.py cmake helper class, the command given to cmake is exactly the same for both versions of export-pkg above. The cmake command value is how I expect it to be with the exception of that the generator given in the profile is not respected, but uses the default given in conan.conf. If no default in conan.conf is given it defaults back to MinGW Makefiles.

A workaround is to set the correct generator as default in conan.conf. But this can only be temporary as projects sometimes includes C# so a mix of generators is to be used.

hi @trondhe,

Could you please share here the code in the package() method of your recipe?

I do not understand why the export-pkg is conditional to CONAN_CMAKE_GENERATOR. Probably you are missing the cmake.configure() before a cmake.install() or something similar.

Thanks!

The setup is identical with another issue I had, and this error appeared when I solved it, as you said by having cmake.configure() in the package method: #4710

It was maybe a bit badly explained, but the issue appears when executing conan export-pkg... which then runs the package method. Then it will run the given cmake.configure() method which sets the variable command which is used to run cmake. This line is set at line 195 in cmake.py. This variable contains the default generator as -G <generator, and not the one specified in the profile given by the conan install... It has also no regard for if the conan export-pkg... command is given a profile argument or not.

Will try to reproduce the error. Thanks for the details!

I have submitted a PR in #4852 trying to solve this issue.

Merged, will be released in next Conan 1.14, please try then and report. Thanks
