Postcompile

Postcompile, or post-compile, refers to the phase in a software build process that occurs after the source has been compiled into object code or a runnable form. It encompasses a range of auxiliary tasks performed to prepare artifacts for distribution, deployment, or runtime. Depending on the toolchain, postcompile tasks may be invoked automatically as post-build actions or as separate steps in the overall build pipeline.

Common postcompile tasks include linking or additional linking steps, resource embedding (such as icons, localized strings, and manifests), embedding version information, and symbol stripping to reduce binary size. They may also cover code signing for distribution, packaging into installers or archives, and producing deployment artifacts like container images or self-contained bundles. Some environments also regenerate configuration data, create checksums, or run post-processing tools such as minifiers or obfuscators for certain languages. Additionally, postcompile steps often copy built artifacts to staging areas or artifact repositories.

In practice, postcompile is implemented by the build system or IDE. Examples include Visual Studio’s PostBuildEvent in MSBuild, Xcode’s Run Script phases, Gradle tasks configured to run after assembly, and CMake or Makefile sequences that include packaging or distribution steps after compilation. The exact mechanics vary by platform and toolchain, but the aim is consistent: transform compiled output into packaged, signed, and deployable artifacts.

Best practices for postcompile work include ensuring determinism and reproducibility, avoiding exposure of secrets, minimizing build time impact, separating artifact generation from deployment logic, and maintaining clear documentation of each postcompile step.
