error while loading shared libraries: libcgfam.so: cannot open shared object file: No such file or directory

[jmccrae]

I am getting the following error in one of my projects. It seems to be a new issue with more recent version of Cargo.

Steps to reproduce

Create a new project

cargo new rustimization_bug

Add rustimization==0.1.1 as a dependency in Cargo.

Create src/main.rs as follows

extern crate rustimization;                                                     
                                                                                
use rustimization::minimizer::Funcmin;                                          
                                                                                
fn main() {                                                                     
                                                                                
    let f = |x : &Vec<f64>| {                                                   
        0.0f64                                                                  
    };                                                                          
    let g = |x : &Vec<f64>| {                                                   
        vec![0.0f64]                                                            
    };                                                                          
                                                                                
    let mut x = Vec::new();                                                     
    let mut fmin = Funcmin::new(&mut x, &f, &g, "cg");                          
    fmin.max_iteration(10);                                                     
    fmin.minimize();                                                            
                                                                                
    println!("Hello, world!");                                                  
}                                                                               

Build the system with cargo build and the running the executable creates the following error

-> % target/debug/rustimization_bug
target/debug/rustimization_bug: error while loading shared libraries: libcgfam.so: cannot open shared object file: No such file or directory

This works with cargo run

-> % cargo run
