Hi there, while this appears to be Rust specific, it is not as I've seen similar strange differences in other complex build situations (e.g. MozillaFirefox), too. The build of rust for Leap 15.1 failed due to the following results of RPMLINT https://build.opensuse.org/package/live_build_log/devel:languages:rust/rust/...: [15022s] rust-src.noarch: E: env-script-interpreter (Badness: 9) /usr/lib/rustlib/src/rust/library/backtrace/ci/android-sdk.sh /usr/bin/env sh [15022s] rust-src.noarch: E: env-script-interpreter (Badness: 9) /usr/lib/rustlib/src/rust/library/stdarch/ci/dox.sh /usr/bin/env bash [15022s] rust-src.noarch: E: env-script-interpreter (Badness: 9) /usr/lib/rustlib/src/rust/library/stdarch/ci/run-docker.sh /usr/bin/env sh [15022s] rust-src.noarch: E: env-script-interpreter (Badness: 9) /usr/lib/rustlib/src/rust/library/stdarch/ci/run.sh /usr/bin/env sh [15022s] rust-src.noarch: E: env-script-interpreter (Badness: 9) /usr/lib/rustlib/src/rust/library/stdarch/ci/style.sh /usr/bin/env sh [15022s] This script uses 'env' as an interpreter. For the rpm runtime dependency [15022s] detection to work, the shebang #!/usr/bin/env python needs to be patched into [15022s] #!/usr/bin/python otherwise the package dependency generator merely adds a [15022s] dependency on /usr/bin/env rather than the actual interpreter /usr/bin/python. [15022s] Alternatively, if the file should not be executed, then ensure that it is not [15022s] marked as executable or don't install it in a path that is reserved for [15022s] executables. [15022s] ... [15022s] 12 packages and 0 specfiles checked; 6 errors, 27 warnings. Interestingly the same messages are shown in the build log for Leap 15.2, but this build succeeded https://build.opensuse.org/package/live_build_log/devel:languages:rust/rust/... Here there is one error less (due to not having to build the included LLVM, but rather use the system provided one), but still 5 errors. I worked around it (see https://build.opensuse.org/request/show/845063), but I don't understand why OBS behaves differently for OSs older than 15.2 and 15.2 onwards (incl. Tumbleweed). Does anyone have an idea? Fix? TIA, cheers. l8er manfred
