# Package Build Process
* Unpack srpm/tar (optional)
* [Parse spec](https://github.com/rpm-software-management/rpm/blob/master/build/parseSpec.c) - see also [build/parse*.c](https://github.com/rpm-software-management/rpm/blob/master/build/)
* If buildarch detected parse spec multiple times - once for each arch with `_target_cpu` macro set
* Build will iterate over all the spec variants and build multiple versions
* Check static build requires
* Execute build scripts (see [doScript()](https://github.com/rpm-software-management/rpm/blob/master/build/build.c#L95)
* %prep
* %generate_buildrequires if present
* re-check build requires - stop build on errors
* %conf
* %build
* %install
* %check - if present
* Process files
* Turn %files lines into actual files (evaluate globs)
* Read from -f param
* Run [file classifiers](https://github.com/rpm-software-management/rpm/blob/master/build/rpmfc.c)
