GuixBuildSystem

Use cases

Guix can be used for faster testing: TODO:

Implementation

Guix currently uses android-make-stub to build Android software using Android.mk.

There are some comments in Guix source code that cross compilation isn't supported for the android-ndk build system.

Practically speaking it means that Guix won't be able to build any BUILD_SHARED_LIBRARY, BUILD_SHARED_LIBRARY or BUILD_STATIC_EXECUTABLE, however building the HOST_* counterpart works fine.

To workaround that they simply do replace them in the Android.mk during the build procedude:

For instance we have:

   (arguments
    `(#:phases
      (modify-phases %standard-phases
             (delete 'bootstrap)
             (add-before 'build 'patch-host
                 (lambda _
                   ;; TODO: Cross-compile.
                   (substitute* "Android.mk" 
                        (("BUILD_SHARED_LIBRARY") "BUILD_HOST_SHARED_LIBRARY")
                        ;; (("BUILD_STATIC_LIBRARY") "BUILD_HOST_STATIC_LIBRARY")
                        ;; (("BUILD_STATIC_EXECUTABLE") "BUILD_HOST_STATIC_EXECUTABLE")
                        )
                   #t))
             )))

Here the (delete 'bootstrap) is because the build is done in several phases, and here the bootstrap phase wasn't overriden by the android-ndk build system yet. As a result it tried to run autogen.sh. That might be because in libsamsung-ipc there is both an android build system and an autotools based one.
