Conan install error

Hi,

I tried to use 'conan-rs' following the steps mentioned. However, I am getting an error as below:

Please let me know how to fix the same.

successfully hardcoded the include path for CXX

I had to hard-code the include path

    let include_path = "/home/emcp/.conan/data/twsapi/10.25.01/stonks/prod/package/2a448472971d7718b4207a1ee198ae4f78f2995d/include";

from my conan-rs installed library.. but is there a better more elegant way to get this wired together with CXX?

build.rs

use std::path::{Path, PathBuf};
use cxx_build::CFG;
use conan::*;


fn main() {
    // requires : sudo apt install libintelrdfpmath-dev
    println!("cargo:rustc-link-lib=bidgcc000");

    let default_conan_profile = "default";

    let command: InstallCommand = InstallCommandBuilder::new()
        .with_profile(&default_conan_profile)
        .build_policy(BuildPolicy::Missing)
        .recipe_path(Path::new("conanfile.txt"))
        .build();

    if let Some(build_info) = command.generate() {
        println!("using conan build info");
        build_info.cargo_emit();

        let twsapi:&BuildDependency = build_info.get_dependency("twsapi").unwrap();

        let twsapi_inc_dir:Vec<&str> = twsapi.get_include_dirs();

        for dir in &twsapi_inc_dir {
            let twsapi_inc_dir_path = Path::new(dir);
            // Add TWSAPI Conan Pkg to Includes
            CFG.exported_header_dirs.extend([twsapi_inc_dir_path]);
        }
    }

    let build_command = BuildCommandBuilder::new()
        .with_recipe_path(PathBuf::from("../../../conanfile.py"))
        .with_build_path(PathBuf::from("../../../build/"))
        .build();

    if let Some(exit_status) = build_command.run() {
       println!("conan build exited with {}", exit_status);
    }

    let include_path = "/home/emcp/.conan/data/twsapi/10.25.01/stonks/prod/package/2a448472971d7718b4207a1ee198ae4f78f2995d/include";

    cxx_build::bridge("src/main.rs")
        .file("src/gettingstarted.cc")
        .include(include_path)
        .flag_if_supported("-std=c++17")
        .compile("twsapi_helloworld");



    println!("cargo:rerun-if-changed=src/main.rs");
    println!("cargo:rerun-if-changed=src/gettingstarted.cc");
    println!("cargo:rerun-if-changed=include/gettingstarted.h");
}

Having trouble grasping once the conan package is added.. how best to call the code.. CXX + ConanRS example?

I have two successful separate projects which I am now trying to sort of combine.

Project #1

a basic conanrs setup which pulls in the C++ recipe I wrote .. but I am unsure how to proceed to use it in rust

Project #2

instantiate this project https://github.com/dtolnay/cxx/tree/master/demo

The challenge

How can I start to call my Conan package code.. like the CXX demo example ? are there tutorials out there showing the way to include C++ code via conan.. and start integrating it properly in a rust program.. in my case it will be a GRPC server wrapping my custom conan packages C++

Progress So Far

I've so far just combined the build.rs of the two

use std::path::Path;
use std::env;

use conan::*;

fn main() {

    let target_os = env::var("CARGO_CFG_TARGET_OS").unwrap();
    let target_arch = env::var("CARGO_CFG_TARGET_ARCH").unwrap();
    let default_conan_profile = "default";
    let _conan_profile = format!("{}-{}", target_os, target_arch);

    let command = InstallCommandBuilder::new()
        .with_profile(&default_conan_profile)
        .build_policy(BuildPolicy::Missing)
        .recipe_path(Path::new("conanfile.txt"))
        .build();

    if let Some(build_info) = command.generate() {
        println!("using conan build info");
        build_info.cargo_emit();
    }

    cxx_build::bridge("src/main.rs")
        .file("src/blobstore.cc")
        .flag_if_supported("-std=c++17")
        .compile("cxxbridge-demo");

    println!("cargo:rerun-if-changed=src/main.rs");
    println!("cargo:rerun-if-changed=src/blobstore.cc");
    println!("cargo:rerun-if-changed=include/blobstore.h");
}

Everything builds fine.. but next I need to learn how to start calling the Conan provided code..

conan generate failures

Hi,

While using 'conan-rs' to integrate rust with conan, I see failures as:

[hello 0.1.0] ======== Finalizing install (deploy, generators) ========
[hello 0.1.0] conanfile.txt: Writing generators to /work/rust-app
[hello 0.1.0] ERROR: Invalid generator 'json'. Available types: CMakeToolchain, CMakeDeps, MesonToolchain, MSBuildDeps, MSBuildToolchain, NMakeToolchain, NMakeDeps, VCVars, QbsProfile, VirtualRunEnv, VirtualBuildEnv, AutotoolsDeps, AutotoolsToolchain, PkgConfigDeps, BazelDeps, BazelToolchain, IntelCC, XcodeDeps, XcodeToolchain, PremakeDeps, MakeDeps, SConsDeps

I am using 'conan2' which doesn't seem to support 'json' as generator. However, install.rs pushes '-g json' for install command.

Could you please help to fix the issue?

BuildDependency with multiple include directories doesn't allow for full usage.

conan-rs/src/build_info/build_dependency.rs

Line 78 in 65a4cb8

self.include_paths.get(0).map(|x| &**x)

This gets only one include, which affected us as we needed to include a new dependency which had three separate include folders.

No option for setting options

In InstallCommandBuilder there is a with_profile and other settings related fluent methods, but there is no method to set options (which are required for using some packages.)

We've worked around this issue for a while locally with environment variables, but it would save us hacking to add something like with_option to set an option.

successfully gotten to compile but project in CXX fails at linker stage

I just wanted to checkin if I am doing something wrong with my conan package.. I have updated my recipe to call out the system library dependency.. but CXX still cannot find my libraries built.. everything works in C++ just fine so I am a bit lost

I added the system library dep like so

def package_info(self):
    self.cpp_info.libs = ["twsapi"]
    self.cpp_info.system_libs = ["bidgcc000"]

https://stackoverflow.com/a/74475762/389976

but seems CXX just cannot find what C++ 's GCC normally can via regular conan

Any thoughts? if it's clearly not a conanRS issue feel free to close, thanks for looking

followed instruction but not seeing my library in the build output

Hi first time getting into Rust.. pivoting away from C++.. and I have a custom Conan recipe that is not public.. but have been using it fairly easily for a year or so..

when I went to try the step-by-step instructions for integrating that conan recipe with my test project.. it failed to show any connection or loading had occurred.. is this because the library is private? or did I miss a step possibly?

Cargo.toml

    let target_os = env::var("CARGO_CFG_TARGET_OS").unwrap();
    let target_arch = env::var("CARGO_CFG_TARGET_ARCH").unwrap();
    let conan_profile = format!("{}-{}", target_os, target_arch);

    let command = InstallCommandBuilder::new()
        .with_profile(&conan_profile)
        .build_policy(BuildPolicy::Missing)

        build_info.cargo_emit();
    }

First, great library!!!

What is the state of this project? It is still maintaned?
