Debug session using copilot suggested the issue explanation is • newer dpkg enables elfpackagemetadata by default (since dpkg 1.22.6ubuntu11), which injects -Wl,--package-metadata=<json> into LDFLAGS between the other flags: -Wl,-Bsymbolic-functions -Wl,--package-metadata=... -Wl,-z,relro -Wl,-z,now . • debian/rules already anticipated this and tries to strip it: sed 's/-Wl,--package-metadata=[^ ]*//g' . That regex removes the flag itself but leaves the two surrounding spaces, producing a double space in LDFLAGS . • BAZEL_LINKOPTS is built by converting spaces to colons ( $(subst $(space),:,...) ) for Bazel. A double space becomes :: , and Bazel's own split_escaped() (in tools/cpp/unix_cc_configure.bzl ) explicitly documents "consecutive delimiters produce empty strings" — so :: yields a literal empty linkopt, which gcc/ld receives as a bare empty filename argument → ld.bfd: cannot find : No such file or directory . I reproduced this exactly locally.
and proposed fix: collapse the extra whitespace after stripping, e.g. in debian/rules : LDFLAGS:=$(shell echo $(LDFLAGS) | sed -e 's/-Wl,--package-metadata=[^ ]*//g' -e 's/ */ /g' -e 's/^ *//;s/ *$$//') -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2167109 Title: bazel-bootstrap 7.7.1+ds-8 FTBFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bazel-bootstrap/+bug/2167109/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
