What is your question?

Conan: Unknown MSVC compiler version [1940]

Have you read the CONTRIBUTING guide?

[X] I've read the CONTRIBUTING guide

memsharded commented 1 month ago

Conan version? Do you have custom settings.yml? If so, please update them.

Please provide more details to reproduce that issue. What files, commands are you using? What is the full output?

RusuDevelopment commented 1 month ago

Conan version? Do you have custom settings.yml? If so, please update them.

Conan version -> 2.5.0 I don't have any custom settngs.yml, it's the default one.

So it seems you are using the cmake-conan integration, this wouldn't be a Conan issue, but a cmake-conan one Moving the ticket to that repo

So i suppose someone else should reply right?

memsharded commented 1 month ago

It seems you are using an outdated cmake-conan version. Please make sure you are using the latest conan_provider.cmake and follow the instructions at: https://github.com/conan-io/cmake-conan, including passing the provider with -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=../conan_provider.cmake

Sorry, I don't know what you mean, or how you are getting that message. Can you please provide detailed and complete reproduction instructions? I'd need a minimal CMakeLists.txt to reproduce, the exact command you are using and the full output.

My CMakeLists.txt:

add_subdirectory(src)
add_subdirectory(vendor)

The command im using: cmake -B build -S . -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=../conan_provider.cmake -DCMAKE_BUILD_TYPE=Release

Output:

CMake Error: CMAKE_PROJECT_TOP_LEVEL_INCLUDES file does not exist: ../conan_provider.cmake

You need to provide the file

Also, the example is not complete, as we don't have the src or vendor CMakeLists.txt. Even if you pass it, we won't be able to reproduce because we don't have those files.

Tell me what you need to be able to help me and i can send you

memsharded commented 1 month ago

It is explained in the readme: https://github.com/conan-io/cmake-conan

Need to put the conan_provider.cmake in the repo, typically close to the CMakeLists.txt
Put a conanfile with the dependencies
Pass the location to your conan_provider.cmake in the -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES

cmake-conan works with a CMake provider. You need to pass the right location to the provider.

RusuDevelopment commented 1 month ago

I did all of that just right now, i put the conan_provider.cmake text to CMakeLists.txt and conanfile.txt then i used this command:

cmake -B build -S . -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=C:\Users\user\Desktop\Unitedtopia\server\conan_provider.cmake -DCMAKE_BUILD_TYPE=Release

& i still get the same error as before

Output:

-- Selecting Windows SDK version 10.0.22621.0 to target Windows 10.0.19045.
CMake Error: CMAKE_PROJECT_TOP_LEVEL_INCLUDES file does not exist: ../conan_provider.cmake

Also if i open the "src" folder wich contains conan.cmake, i still get the

CMake Error at conan.cmake:61 (message): Conan: Unknown MSVC compiler version [1940]

memsharded commented 1 month ago

Also if i open the "src" folder wich contains conan.cmake, i still get the

conan.cmake doesn't exist anymore, it shouldn't be a folder, it shouldn't be a file. The only file that should exist is the conan_provider.cmake.

I think there is still something else that is not being reported. If you are providing:

cmake -B build -S . -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=C:\Users\user\Desktop\Unitedtopia\server\conan_provider.cmake -DCMAKE_BUILD_TYPE=Release

The error message:

CMake Error: CMAKE_PROJECT_TOP_LEVEL_INCLUDES file does not exist: ../conan_provider.cmake

doesn't make sense. This is CMake, not Conan doing this, and CMake is just failing to find that file, so there is someone else somewhere setting CMAKE_PROJECT_TOP_LEVEL_INCLUDES

conan.cmake is a file, not a folder, i said it;s located in the "src" folder. One of the CMakeLists.txt has this ->

   include(${CMAKE_CURRENT_SOURCE_DIR}/conan.cmake)

If you sayin that this is because of CMake, what am i supposed to do?

memsharded commented 1 month ago

include(${CMAKE_CURRENT_SOURCE_DIR}/conan.cmake)

This is legacy Conan 1 integration, shouldn't be used anymore. The conan.cmake has been replaced by the conan_provider.cmake. This should be removed. You are mixing both Conan 1 and Conan 2 in the same project, this is not possible.

It's an old project that i decided to continue.

So i figured something and i replace a few things. After using the command cmake -B build -S . -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=C:\Users\user\Desktop\Unitedtopia\server\build\cmake-conan/conan_provider.cmake -DCMAKE_BUILD_TYPE=Release

The output is now:

The error message indicates you are doing something else than passing -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES, you might have added an include() to it or something like that. Please provide full reproduction details, including all the CMakeLists.txt involved, otherwise it is not possible to help.

did you solve the problem?

mferrera commented 3 weeks ago

I was able to solve this for conan<2 like so:

Store conan.cmake locally
Modify this condition: https://github.com/conan-io/cmake-conan/blob/df0f64a0920eab35033b17cc1104aa8b37af204f/conan.cmake#L58-L59 to:
```
elseif(NOT MSVC_VERSION VERSION_LESS 1930 AND MSVC_VERSION VERSION_LESS 1949)
```
This resolves MSCV_VERSIONS up to <1949 to Visual Studio 17. 1949 is chosen arbitrarily above 1940, the source of the error
