Building RPMs

The Makefile contains steps that will build RPMs using the locally-configured rpmbuild environment.

However, a better approach is to use mock which ensures all packages are built in a standard, reproducible environment, and also allows building for targets other than that of the local machine.

The steps to build RPMs with mock are:

• Create tarball + generate spec file from template

  cd packaging/rpm
  make clean && make buildtargz
  

• Create SRPM from tarball and spec file

  mock -r epel-7-x86_64 --buildsrpm --spec qpsmtpd.spec --sources build
  mv /var/lib/mock/epel-7-x86_64/result/*.src.rpm build
  

3. Build RPMs from SRPM

   mock -r epel-7-x86_64 build/*.src.rpm
   mv /var/lib/mock/epel-7-x86_64/result/*.rpm build
   

This builds packages named using the content of the PACKAGE, VERSION, and RELEASE files in the packaging/rpm directory.

These can be overridden on the command-line when building the tarball.

For example, to append the local git commit hash to the RELEASE:

make clean && make buildtargz RELEASE="$(<"RELEASE").$(git rev-parse --short HEAD)"

This will produce a tarball named something like qpsmtpd-0.96-1.83b6aaf.tar.gz
