I suggest that you take a look at the Rust packaging guidelines, or at how other packages in similar situations have handled this. You need to configure the cargo build system correctly, i.e. 1. tell it to not try to download dependencies over the internet, 2. tell it how to use dependencies from Fedora instead, 2. use correct cargo build flags, and 3. use correct Rust compiler flags. All these should be possible without too much trouble: A. Add a call of the "%cargo_prep" macro in the "%prep" scriptlet. Probably doesn't matter where, except that it needs to be after unpacking sources. This sets up cargo configuration that disables loading dependencies over the internet, and specifies the location where cargo can find packaged Rust dependencies. B. Add a build dependency on the "cxx" crate. I looked at the source code, and it seems to be the only Rust dependency - and it's already packaged for Fedora: BuildRequires: (crate(cxx/default) >= 1.0.0 with crate(cxx/default) < 2.0.0~) C. Make sure "cargo build" is called with the correct flags for cargo and the Rust compiler. It looks like cmake just calls "cargo build --release", which ignores Fedora default compiler flags (which is forbidden). You can look at the "%cargo_build" flag for which flags you need: $ rpm -E "%cargo_build" /usr/bin/env CARGO_HOME=.cargo RUSTC_BOOTSTRAP=1 RUSTFLAGS='-Copt-level=3 -Cdebuginfo=2 -Ccodegen-units=1 -Clink-arg=-Wl,-z,relro -Clink-arg=-Wl,-z,now --cap-lints=warn' /usr/bin/cargo build -j16 -Z avoid-dev-deps --release I think RUSTC_BOOTSTRAP=1 is not necessary in this case, but at least setting RUSTFLAGS is mandatory (for example, debuginfo doesn't work if you don't, and these flags also produce better code at the cost of slightly slower compile times). I haven't looked at how cmake calls "cargo build --release", but you might need to patch the CMakeLists.txt file that contains this call to include the flags above, and/or set RUSTFLAGS environment variable before running the build.
