Buildroot Package Compilation

We can execute make <package> to compile a package separately. The compilation of the software package mainly includes the process of downloading, decompressing, patching, configuring, compiling, and installing. For details, please refer to package/pkg-generic.mk.

  • Download

    Buildroot will automatically obtain the corresponding software packages from the Internet according to the configuration package/<package>/<package>.mk, including some third-party libraries, plug-ins, utilities, etc., and place them in the dl/ directory.

  • Unzip

    The package will be decompressed in the output/rockchip_rk3568/build/<package>-<version> directory.

  • Patch

    Patches are placed in the package/<packgae>/ directory, and Buildroot will apply the corresponding patches after decompressing the package. If you want to modify the source code, you can modify it by patching.

  • Configure

  • Compile

  • Install

    After the compilation is completed, the required compilation files will be copied to the output/rockchip_rk3568/target/ directory.

For a certain package, we can call a certain step in the package construction through make <package>-<target>, as follows:

Package-specific:
  <pkg>                  - Build and install <pkg> and all its dependencies
  <pkg>-source           - Only download the source files for <pkg>
  <pkg>-extract          - Extract <pkg> sources
  <pkg>-patch            - Apply patches to <pkg>
  <pkg>-depends          - Build <pkg>'s dependencies
  <pkg>-configure        - Build <pkg> up to the configure step
  <pkg>-build            - Build <pkg> up to the build step
  <pkg>-graph-depends    - Generate a graph of <pkg>'s dependencies
  <pkg>-dirclean         - Remove <pkg> build directory
  <pkg>-reconfigure      - Restart the build from the configure step
  <pkg>-rebuild          - Restart the build from the build step
