error: failed to select a version for clang-sys

[yzhang71]

Hi team,

I have successfully built WARF on my machine running Ubuntu 18.04, but when I run the command "make test ", the following error occurs. Could you provide any help?

cargo +nightly build --release --out-dir=. -Z unstable-options

versions that meet the requirements ^1 are: 1.6.0, 1.4.0, 1.3.3, 1.3.2, 1.3.1, 1.3.0, 1.2.2, 1.2.1, 1.2.0, 1.1.1, 1.1.0, 1.0.3, 1.0.2, 1.0.1, 1.0.0

the package clang-sys links to the native library clang, but it conflicts with a previous package which links to clang as well:
package clang-sys v0.29.3
... which satisfies dependency clang-sys = "^0.29" of package bindgen v0.54.0
... which satisfies dependency bindgen = "^0.54.0" of package fizzy v0.6.0-dev
... which satisfies dependency fizzy = "^0.6.0-dev" of package fuzz-targets v0.1.0 (/home/dennis/Documents/Rust_Project/Fuzzing_Wasmer/wasm_runtimes_fuzzing/warf/workspace/targets)
... which satisfies path dependency fuzz-targets of package fuzz-targets-libfuzzer v0.1.0 (/home/dennis/Documents/Rust_Project/Fuzzing_Wasmer/wasm_runtimes_fuzzing/warf/workspace/libfuzzer/fuzz)
Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the links ='clang-sys' value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.
