It assumes that you already have +adb and root through adb setup. + +First you need to stop the RIL daemon because ipc-modem currently +doesn't support running in parallel of the RIL or other programs that +talk to the modem: +$ sudo adb root +$ sudo adb shell stop ril-daemon + +Then we can tell Guix to build everything for us. +$ echo '(list libsamsung-ipc-static)' >> scripts/guix.scm +$ guix build --target=arm-linux-gnueabihf --file=scripts/guix.scm + +Note that adding '(list libsamsung-ipc-static)' scripts/guix.scm is +not only used to shorten the build time, but it is also necessary +because the Android packages in that file don't cross compile due to +some limitations in Guix. + +If the build succeeds, it will print the path where you can find the +result of the build, it will look like that: +/gnu/store/<some hash>-libsamsung-ipc-static-0.0-HEAD.<some hash> + +You can then copy the binary on the phone and test libsamsung-ipc: +$ sudo adb push \ + /gnu/store/<hash>-libsamsung-ipc-static-0.0-HEAD.<hash>/bin/ipc-modem \ + /storage/ + +And run it: +$ sudo adb shell /storage/ipc-modem start --debug --call=<local number to call>
