Created attachment 577780 [details] all relevant log-files Hello, the configure script for firefox 60.7.0 fails while looking for the rustc command - the offending line is: ### output of: rustc -V -v: rustc 1.34.2 binary: rustc commit-hash: unknown commit-date: unknown host: i686-unknown-linux-gnu release: 1.34.2 error: failed to find a `codegen-backends` folder in the sysroot candidates: * /usr * /usr/lib ### temporary workaround: cd /usr/lib/rust-1.34.2/rustlib/i686-unknown-linux-gnu ln -s ../../rust-1.34.2/rustlib/i686-unknown-linux-gnu/codegen-backends ### retry: rustc -V -v: rustc 1.34.2 binary: rustc commit-hash: unknown commit-date: unknown host: i686-unknown-linux-gnu release: 1.34.2 LLVM version: 8.0 After applying the above workaround, both firefox and thunderbird will compile fine. Inside the tgz archive you'll find all necessary information, including the build.log for firefox. CU Tom
