| 9 | # Linker flags are a string: a typo in one produces a binary that builds, links |
| 10 | # and runs, and quietly reports the wrong version — or "unknown". Nothing but |
| 11 | # running the binary catches that, so the build runs it. |
| 12 | # |
| 13 | # With a version to expect, the reported number must **equal** it. A substring |
| 14 | # test is not enough: "0.2.0" is a substring of "10.2.0" and of a commit hash |
| 15 | # that happens to contain it, and the case this exists to catch is a stamp that |
| 16 | # is nearly right. |
| 17 | # |
| 18 | # With no version to expect — a build outside a git checkout, where there is |
| 19 | # nothing to describe — the only claim left is that some source named it, so |
| 20 | # "unknown" is the failure. |
