It is decentralized, portable, and multi-platform, running on many operating systems, such as Windows . Once there you will issue the following set of commands to create a build folder, change director to that folder, install needed software using conan, and finally use cmake to build and install thge applications. (Note: . Also, the best that can be done is restricted to CMake (and maybe a some others) build system, when conanbuildinfo.cmake is used (which is not strictly necessary). But Conan thought that the dependencies were built with gcc 5.4 (because for whatever reason this was set in the default profile). The "conan(.exe) install" commands below will install the built binaries also to your current working directory so you may want to: mkdir build_dir && cd build_dir; Windows MSVC2019: For MSVC compiler open command prompt and execute vcvars64.bat The main problem is that you have to keep your profile in sync with the compilers you have installed - if you don't, you get an inconsistent state in your built packages. To manage the different configurations and the ABI compatibility, Conan uses "settings" (os, architecture, compiler…). In order to build I had to add gcc 11 to the conan settings in order to allow this compiler. A typical example is when users define custom settings to account for the glibc version, or for different linux distros RH6 vs RH7. It is possible to add new settings at the root of the settings.yml file, something like: If we want to create different binaries from our recipes defining this new setting, we would need to add to How does this 8080 code perform division with remainder? Now Conan supports the Intel compiler. If you customize your settings.yml, you can share, distribute and sync this configuration with your team 3,169 views. I agree that there is place for improvement here, but I also think that part of the conan flexibility to adapt to many different situations and environment is precisely because it is very agnostic of these things.

I am developing on macOS with Apple-clang v12 being the default compiler via the Xcode installation. I would like to add another corner case, if you have a cross build toolchain as a build require, like the Android NDK, until the dependency graph is computed you will never know the usage to the toolchain, even looking at the standard CXX and CC vars, even the OS setting won't match, and as Diego said, you only could know that something is not matching at the build system level. I've read your proposal and I agree it's likely a good piece to a final solution. And even if conanbuildinfo.cmake adds those checks, it can happen that conanbuildinfo.cmake is not used at all (though we suggest that it is good to use it), for example, if the package being created doesn't have transitive dependencies. Adding a native library native-lib and linking it with the Boost libraries.. Open the app/build.gradle file: different platforms, for example the standard C++ library (compiler.libcxx) exists for the gcc compiler, The dependencies were built with gcc 4.9 and so was the consuming project. Another problem I see is with Xcode on macOS - since it comes with the compiler, you always have to remember to keep the conan profile in sync with it, making sharing the conan profiles impractical. If not using cmake, mismatches can go undetected. In the CLion settings I have already overwritten the c++ compiler with the llvm v11.1 compiler: What's the correct solution to properly configure both to use the llvm v11.1 compiler?

Made the change and got deep into it all the way to: CMake Generate step failed. The "0.1" version is the version of the installer recipe, not the MinGW nor CMake tools. for Android or Raspberry Pi). You can remove compilers, OS, architectures, etc. Conan uses python recipes, describing how to build a library by explicitly calling any build system, and also describing the needed information for the consumers (include directories, library names etc.). One of the biggest advantages againts Maven is that conan manages very well some aspects needed by native applications, like: compiler and its version, system architecture (x86, x64, etc), operative system, etc. The branches in this repo are: develop: PR are merged to this branch.Latest state of development .

Build the Additional Library conan package. Based on the above, We can assume that our current directory contains a lib folder with a number binaries for this "hello" library libhello.a, compatible for example with Windows MinGW (gcc) version 4.9: conan export-pkg . This would at least alert people to the inconsistency. To build the applications you need to now navigate to the SimCenterBackendApplications folder that was created with the git clone command. In case, for example, of a header only library, package mantainer can "disable" compiler and compiler.version settings, so the package will be the same for all compilers. For example, I think that setting CC/CXX on macosx with apple-clang and llvm clang installed is not sufficient. The first invocation has CMake think Apple-clang is my compiler while conan is configured to use the llvm version and on the second step (most likely invoked by conan_basic_setup in my CMakeLists.txt) the correct CMake compiler is chosen but Conan ends up without a profile hence a version mismatch.

Those settings and options can come from the command line, profiles or from the values cached in the latest conan install execution. I personally do not want to enable the CONAN_DISABLE_CHECK_COMPILER CMake variable as it is unclear which compiler will be used to compile dependencies in the end. For the first issue, yes, we still have to improve the error checking to catch errors earlier. rev 2021.10.6.40384. Software.
