shared library error when using indoc

[glennpierce]

I am using a nightly compiler and when I use indow I get the error

./target/debug/lasso: error while loading shared libraries: libstd-9f780c2031976271.so: cannot open shared object file: No such file or directory

When running my executable directly.

I have not been able to reproduce this yet. Could you provide some more details? Are you using indoc from a no_std crate? Is your crate a library or binary? What is the date of the nightly you are using? Does it work with the stable compiler? What platform are you on? Do other procedural macro crates work? Can you share a minimal piece of code that reproduces this?

So I have a library I developed and some tests that use this library.

In my Cargo.toml I have included indoc = "0.2"
That's works.

when I include the lib in lib.rs with

#[macro_use]
extern crate indoc;

I get

./target/release/lasso: error while loading shared libraries: libstd-9f780c2031976271.so: cannot open shared object file: No such file or directory

My compiler is

nightly-x86_64-unknown-linux-gnu
rustc 1.21.0-nightly (b75d1f0ce 2017-08-02)

Trying with the crate quote = "0.3" things seem to work.

I can't try stable as I depend on cron crate that does not work on stable. If you still can't replicate I can start trying to remove code.

Thanks

Also on nightly-x86_64-unknown-linux-gnu, this script succeeds for me. Any idea what is different in your setup?

#!/bin/bash

cargo new repro
cat >> repro/Cargo.toml <<-'EOF'
    indoc = "0.2"
EOF

cat > repro/src/lib.rs <<-'EOF'
    #[macro_use]
    extern crate indoc;
    
    pub fn f() -> &'static str {
        indoc!("1
                2")
    }
    
    #[test]
    fn test_indoc() {
        assert_eq!(f(), "1\n2");
    }
EOF

rustc +nightly-2017-08-03 --version

Ok

Change Cargo.toml to

[package]
name = "repro"
version = "0.1.0"
authors = ["Glenn Pierce glennpierce@gmail.com"]

[dependencies]
indoc = "0.2"

[lib]
name = "libtest"
path = "src/lib.rs"
test = false
bench = false

[[bin]]
name = "test"
path = "test/test.rs"

test/test.rs

extern crate libtest;

fn main() {

}

cargo build --release --bin test
./target/release/test
./target/release/test: error while loading shared libraries: libstd-8eeda694d27cc3ba.so: cannot open shared object file: No such file or directory

I also tested this on stable with the same result

Thanks, I was able to reproduce this. I reported it in rust-lang/cargo#4651 as a Cargo bug.

[dtolnay]

I implemented a workaround in ac5c069. Could you confirm that you are able to run binaries depending on indoc 0.2.2?

[glennpierce]

Yep that seems like it is fixed. Thanks
