Conan install error

[vithalsm]

Hi,

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

Running `/home/rust-test/rust/rust-conan/target/debug/build/rust-conan-ab89c5392bdc9e1a/build-script-build`

Please let me know how to fix the same.

I could surpass (or mask) the above error by adjusting the input value from the build.rs (listed below). I believe, problem is due to below code snippet, in which argument '-if' is used. Wondering whether it should be '-of' rather.

let output_dir = self.output_dir(); if let Some(output_dir) = &output_dir { let current_dir = env::current_dir()?.to_path_buf(); if output_dir != &current_dir { <<<<<< By passing same value as being derived here, skipped below lines where '-if' is being passed. args.extend(&["-if", output_dir.to_str().unwrap()]); } }

my build.rs >>>>>>>>>> fn main() { let conan_profile = "default"; let opts = ["sign", "True"]; let _cur_dir = env::current_dir().unwrap(); let _dest_path = Path::new(&_cur_dir);

let command = InstallCommandBuilder::new()
    .with_profile(&conan_profile)
    **.with_options(&opts)**
    .build_policy(BuildPolicy::Missing)
    .recipe_path(Path::new("conanfile.txt"))
    **.output_dir(&_dest_path)**
    .build();

Fixed above issue, this is due to the way 'options' being sent to 'install' command. Help text needs to be adjusted.

@vithalsm , I believe I hit a similar problem as you.. and the fix was to remove the following line from the example

        .with_option("sign", "True")

Seems that a PR would help the original author if you can confirm

Hi @EMCP, Yes, it can be removed. However, the right API is .with_options(...). Documentation needs to be fixed with name and signatures.
