|  | 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 |
