h1. GuixBuildSystem
h2. Use cases
Guix can be used for faster testing:
* It can build software that uses autotools and Android.mk Makefiles
* We might be able to use it to iterate over different Android versions, to test libsamsung-ril changes for various RIL API way faster (without even having to use it in a specific Replicant version, use repo, etc).
* It's more self contained than the whole Replicant source code
TODO:
* Import the compilation flags for various Replicant versions like -Werror -Wnounused to make sure that everything is usable in all Replicant versions.
* Finish packaging libsamsung-ril
* Add more automatic testing either in libsamsung-ipc / libsamsung-ril and or in the unofficial Guix packages.
h2. Implementation
Guix currently uses "android-make-stub":https://github.com/daym/android-make-stub.git 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:
* BUILD_SHARED_LIBRARY becomes BUILD_HOST_SHARED_LIBRARY
* BUILD_SHARED_LIBRARY becomes BUILD_HOST_STATIC_LIBRARY
* BUILD_STATIC_EXECUTABLE becomes BUILD_HOST_STATIC_EXECUTABLE
For instance we have:
<pre>
(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))
)))
</pre>
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.
