Event Timeline
| contrib/extract-secp256k1.sh | ||
|---|---|---|
| 4 ↗ | (On Diff #15133) | Rather than follow the linter's advice regarding pushd ... || exit, use something like set -euo pipefail instead. The set -eu is also good practice either way. |
| 9 ↗ | (On Diff #15133) | use mktemp -d rather than a hardcoded workdir. |
| 26 ↗ | (On Diff #15133) | Call this in an exit trap that is set right after the creation of the directory so that it cleans up if the script fails at any point. |
| contrib/extract-secp256k1.sh | ||
|---|---|---|
| 8 ↗ | (On Diff #15150) | wokdir -> workdir |
| contrib/extract-secp256k1.sh | ||
|---|---|---|
| 36 ↗ | (On Diff #15168) | This will fail if secp256k1 already exists. Since the script takes a long time to run, the beginning of the script should bail early if this output dir already exists. |

Note that some cmake modules (from cmake/modules) are required to build secp256k1 with cmake.
This can be easily solved by copying the necessary files to new repo and setting the module path accordingly.
I can do it in a follow-up if desired.
Comment Actions
Nit: I would prefer quoted echo statements, but this is probably best left to a linter.

This produces some lint advice (the only output right now if you run arc lint --everything)
