[bug] conan create throws compiler.cppstd 14 vs 17 compatibility error

Open raja777m opened this issue 9 months ago • 4 comments

Describe the bug

Task is to generate static libraries out of the SDKs we currently have for various OSs.

I have generated the artifacts for my project, use it to run a conan install and cmake in the build_release folder.

I was able to generate a single lib (I changed all the settings to false where it says SHARED - so instead of .lib, .dll and some other file, it generated .lib only).

but when I run conan create ., it complains

poco/1.13.3#00..... Invalid


ERROR: There are invalid packages:
poco/1.13.3: Invalid: Current cppstd (14) is lower than the required C++ standard (17).

having 14 vs 17 CMAKE_CXX_STANDARD issue. I made sure CMakeLists file sets this parameter to 17.

even ran the command with 17 explicitly mentioned:

conan install . -o xf_iam_client/*:shared=False --output-folder=build_release --build=missing --profile build_profiles\win_x86_64_msvc_17_193_Release -s compiler.cppstd=17 -v trace

Need help with this error. thanks.

other things I did:

  1. Installed MSVC 2019 first, then downloaded 2022.

  2. cleared cache, cleaned the builds, rebuild the file structure, build_release folder is deleted and started over the process using

    cmake --build . --config Release

  3. explicitly ran this in the command: "-s:b compiler.cppstd=17" with no luck. Still face the same issue.

How to reproduce it

Hi @raja777m

Thanks for your question.

Can you please provide the full output of your command:

conan install . -o xf_iam_client/*:shared=False --output-folder=build_release --build=missing --profile build_profiles\win_x86_64_msvc_17_193_Release -s compiler.cppstd=17 -v trace

It is the same error you are seeing with your conan create command?

The above is what I get for: conan create .

I get this happy message: Install finished successfully

when I run: conan install . -o xf_iam_client/*:shared=False --output-folder=build_release --build=missing --profile build_profiles\win_x86_64_msvc_17_193_Release -s:b compiler.cppstd=17 -v trace

You need to pass the same arguments to the conan create, specially the compiler.cppstd=17, so something like:

conan create  .  <other args, profile, etc> -s compiler.cppstd=17
