# build prerequisites

The build process of libraries (started by https://github.com/compiler-explorer/infra/blob/main/admin-daily-builds.sh)
has a couple of safeguards to not build libraries allday everyday, namely:

- The compiler needs to have supportsBinary=true on in the current
  https://github.com/compiler-explorer/compiler-explorer/blob/main/etc/config/c%2B%2B.amazon.properties
- If all libraries are being built, only a commit hash change will result in a new build.
- If a particular compiler has failed to produce a valid build, it will be marked and will not build the library with
  this compiler anymore.
- There are a couple of hardcoded exceptions that never attempt the build, these can be found in
  https://github.com/compiler-explorer/infra/blob/main/bin/lib/library_builder.py#L29
- You can manually trigger a forced-build, by setting the `--build-for=compilerid` parameter, which can also be set by
  changing the 2nd parameter here -> https://github.com/compiler-explorer/infra/blob/main/admin-daily-builds.sh#L104
- If you want to trigger all compilers to rebuild a certain library, you will need to manually delete the logging
  related to this library.

# manually delete logging

You have to login to the conan instance and delete records from the sqlite database responsible for keeping the logging.

Example:

```
ce conan login
sudo -u ce sqlite3 /home/ce/.conan_server/buildslogs.db
delete from latest where library='unifex' and success=0;
```

You can find more info about the database in https://github.com/compiler-explorer/conanproxy/blob/main/build-logging.js
