Steps to reproduce

I Just create a example conanfile.py

from conan import ConanFile
from conan.tools.cmake import CMakeToolchain, CMake, cmake_layout
from conan.tools.scm import Git
from conan.tools.build import check_min_cppstd

class helloRecipe(ConanFile):
    name = "hellofmt"
    version = "1.0"

    # Optional metadata
    license = "<Put the package license here>"
    author = "<Put your name here> <And your email here>"
    url = "<Package recipe repository url here, for issues about the package>"
    description = "<Description of hello package here>"
    topics = ("<Put some tag here>", "<here>", "<and here>")

    # Binary configuration
    settings = "os", "compiler", "build_type", "arch"
    options = {"shared": [True, False], "fPIC": [True, False]}
    default_options = {"shared": False, "fPIC": True}

    generators = "CMakeDeps"

    def validate(self):
        check_min_cppstd(self, "11")

    def source(self):
        git = Git(self)
        git.clone(url="https://github.com/conan-io/libhello.git", target=".")
        # Please, be aware that using the head of the branch instead of an immutable tag
        # or commit is not a good practice in general
        git.checkout("require_fmt")

    def requirements(self):
        self.requires("fmt/9.1.0")

    def config_options(self):
        if self.settings.os == "Windows":
            del self.options.fPIC

    def layout(self):
        cmake_layout(self)

    def generate(self):
        tc = CMakeToolchain(self)
        tc.generate()

    def build(self):
        cmake = CMake(self)
        cmake.configure()
        cmake.build()

    def package(self):
        cmake = CMake(self)
        cmake.install()

    def package_info(self):
        self.cpp_info.libs = ["hellofmt"]

profile

[settings]
arch=x86_64
build_type=Release
compiler=clang
compiler.cppstd=gnu14
compiler.libcxx=libstdc++11
compiler.version=15
os=Macos

Run the command conan create . --version 9.1.0 --build=missing -vvv

And I just copy https://github.com/conan-io/conan-center-index/tree/master/recipes/fmt/all to my local and run conan create . --version 9.1.0 --build=missing -vvv happen same error

Logs

main error log: ld: library not found for -lstdc++

No problem with same compile command in debian.

memsharded commented 1 year ago

Hi @CaiJingLong

Thanks for your report. Quick question: you sure you want to use the clang compiler in OSX, and not the default and recommended one apple-clang? All packages in ConanCenter are built and tested with apple-clang, it might be possible that there could be issues with that clang compiler. In case it is clang if you can report a bit how it was setup, that also helps. Also if you can try with apple-clang and report if it works or not. Thanks.

CaiJingLong commented 1 year ago

I know why happen the problem.

I created the default profile with conan profile detect --force.

Next, I open the default profile:

[settings]
arch=x86_64
build_type=Release
compiler=clang
compiler.cppstd=gnu14
compiler.libcxx=libstdc++11
compiler.version=15
os=Macos

My problem is stdc++ cannot be found, so I need change the compiler.libcxx.

-- compiler.libcxx=libstdc++11
++ compiler.libcxx=libc++

And, I build success.

Therefore, if possible, the guess of Conan's automatic profile generation may need to be modified, which is very unfriendly to Conan's beginners.

memsharded commented 1 year ago

Quick question: your conan profile detect in Conan 2.0 detects clang instead of apple-clang? Do you have installed xcode and standard dev tools in your OSX machine, or not? Maybe you just installed clang and not xcode?

The default from conan profile detect could be changed if it makes sense, re-opening to check it.

CaiJingLong commented 1 year ago

I installed XCode before conan, I'm a mobile developer.

I don't know whether the conan create command calls apple-clang or clang in the default profile.

Remove the old default profile withrm $(conan profile path default). Run theconan profile detect, and cat $(conan profile path default):

[settings]
arch=x86_64
build_type=Release
compiler=clang
compiler.cppstd=gnu14
compiler.libcxx=libstdc++11
compiler.version=15
os=Macos

CaiJingLong commented 1 year ago

When the default profile, error log have next part:

-- The CXX compiler identification is AppleClang 14.0.0.14000029

....

The C++ compiler
    "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++"

memsharded commented 1 year ago

Thanks for the feedback @CaiJingLong

This is quite unexpected, that you run conan profile detect in a machine with Xcode (and I assume xcode comes with the c++ compilers?) and it detects clang compiler instead. It might be possible if only the AndroidNDK is installed in the machine, because Android uses clang, but otherwise it is surprising. But as you commented, The CXX compiler identification is AppleClang 14.0.0.14000029 shows that there is a valid CXX compiler there, so not sure why the conan profile detect will not define it.

If you could run conan profile detect --force and share the output here, that might give some hints.

CaiJingLong commented 1 year ago

CaiJingLong commented 1 year ago

The system have two clang.

By default, I run conan profile in the zsh shell. However, whether I use sh or bash, I get the clang under the llvm by default.

However, when I run the conan create command, reading the default profile, the compiler tool seems to become apple-clang in xcode, which is the reason why libc++ cannot be found.

CaiJingLong commented 1 year ago

Conan profile detect uses llvm-clang by default. Use llvm-clang
Conan create uses apple-clang after reading the default profile. Use apple-clang.

This seems to be related conan profile find clang with order in $PATH, but it does not follow the same principle when conan create.

memsharded commented 1 year ago

Thanks very much for the feedback.

Lets go step by step:

If you have a clang compiler in the PATH with higher priority than the default apple-clang, that will be the one detected by conan profile detect, so the result in that case makes sense that it returns clang and not apple-clang
The incorrect thing for clang was defaulting to libstdc++11, I am proposing to fix that in https://github.com/conan-io/conan/pull/13359 for next Conan 2.0.2 release.
In any case, as the conan profile detect docs and output message reads, the result of it shouldn't be blindly trusted, and it is recommended that users check it and for production, even providing their own profile files instead of detecting them

What we would need to know a bit more of detail is the other possible errors when building packages. If you could test in your computer (check the arch is correct, if using a modern M1, you need to change it too):

profile "clang":

[settings]
arch=x86_64
build_type=Release
compiler=clang
compiler.cppstd=gnu14
compiler.libcxx=libc++
compiler.version=15
os=Macos

profile "appleclang":

[settings]
arch=x86_64
build_type=Release
compiler=apple-clang
compiler.cppstd=gnu17
compiler.libcxx=libc++
compiler.version=14
os=Macos

conan new cmake_lib -d name=pkg -d version=0.1
conan create . -pr=clang
conan create . -pr=appleclang

And report the full output of both "create" commands, that would hep to understand a bit better what could be failing.

Currently, it does not follow the configuration of profile to use cxx compile. The input of profile is clang or apple-clang, but cxx compile of pkg build and test_package is always apple-clang.

memsharded commented 1 year ago

Thanks very much for the feedback.

To clarify, the purpose of the "profile" is not to configure the environment (compiler) in any way, it is just a declaration of what is supposed to be the configured environment that is going to be used, to define the binary package_id identifier that will be created. But it is the responsibility of the user to setup the environment to match the declared settings in the profile.

In your case, there is indeed a configuration problem:

You have a clang compiler that is not the standard apple-clang in the path with higher priority, so conan profile detect detects it.
As the output of conan profile detect reads, its result doesn't intend to be perfect or stable, just a "best effort guess"
But when CMake executes, it doesn't get the clang (different shell, if I understood correctly) compiler, but the apple-clang one

It seems that Conan can't do much here (besides the bug with the PR to be fixed for libc++), but it is a matter of setup. Depending on what to do, it would make sense to use different approaches, but in the end is how to configure CMake to use the compiler you want. Do you really want to use clang or apple-clang (apple-clang is the standard in OSX)? Do you want to alternate between both compilers for different purposes?

CaiJingLong commented 1 year ago

My goal is compile lib success and make it available.

If the function of profile is not specified but declared, then I understand, but the package manager should not be just that.

The compilation speed and default compilation configuration of different compilers are different, so the compiler specified in the profile should be more intuitive "what you get is what you see". I mean that llvm-clang is configured in the profile, so llvm-clang should be used when compiling. The same is true for gcc or apple-clang.

Ps: Multiple clang are not my requirement, but because the binary installed by brew will be higher in PATH than the '/usr/bin' directory. A vscode plugin is required by cquery, and cquery required by llvm, so the llvm was installed.

memsharded commented 1 year ago

If the function of profile is not specified but declared, then I understand, but the package manager should not be just that.

yes, the role of a package manager is to install packages, not to configure the environment. Because, for a start, there are some mainstream compilers that cannot be even redistributed by third parties, like the Microsoft VS compiler. If Conan is not allowed to distribute and setup that compiler, then this is impossible. Same happens for Apple OSX (and iOS, etc) toolchains.

So installing and configuring the environment like compiler needs to be managed by users, there is no other possibility.

If Conan cannot have control over that, then it is almost impossible to guarantee that a Conan profile can configure the environment in the expected way. What was happening in your case is a good example. Conan "sees" a clang compiler in the path with higher priority, so it thinks "ok, there is a compiler in the path, it is clang 15, lets use it", and then your environment changes that and that compiler is no longer the one, and other tools like CMake will not see it with higher priority. What Conan can do? It just detected clang 15 because it was there in the path, and it worked (conan executed clang --version to get its version)

this issue has been closed by https://github.com/conan-io/conan/pull/13359, fixing the libc++ detection in conan profile detect for clang compiler in OSX.

As commented above, there is little Conan can do about the configuration of the compiler in the system, but please open new tickets if you have any further questions. Thanks!
