I have moved your post to a new help topic. Please read our post on Forum Code Formatting and Syntax Highlighting, which explains how to make your post readable.

Did you add gimli to your Cargo.toml?

#3

I have some questions to ask before continuing on this topic:

  • What is your operating system and computer architecture ?
  • How did you install Rust toolchains?
#4

yes i added

#5

Ubuntu x64

#6

It seems like you are compiling with rustc directly. You need to compile with cargo.

#7

cargo simple.rs?

#8

Cargo requires the files to be laid out in a certain way. You can read about it here.

#9

In particular, cargo run --example simple should run the simple.rs example from the directory with the gimli sources, if that's what you're trying to do.

#10

Getting this with the command you told:

For more information about this error, try rustc --explain E0463.
error: could not compile gimli.

To learn more, run the command again with --verbose.

Please read Forum Code Formatting and Syntax Highlighting, which I already linked once, and edit your posts accordingly.

#12

ok

#13

It looks like you may have ended up with two versions of gimli there. Have you changed the Cargo.toml?

#14

yes.
added the dependency given in the guide

#15

If you are building the gimli package itself, you don't need to add any dependencies or edit any files. Just run cargo run --example simple in an unmodifed copy of the gimli repository.

If you want to create a new package that depends on gimli, you can use cargo new to create the package, then add the dependency to Cargo.toml and paste the example code into src/main.rs.
