Adding support for Android (Termux)

[Sam2159]

Some changes needed to run this project also on Android.

For the wiki:
The commands to install the dependencies are:

pkg install glib cmake git wget autoconf nettle ninja binutils x11-repo mesa git dtc zlib ninja cmake gnutls capstone xorgproto && pkg install sdl2 mesa-dev libtasn1 xorg-server xterm fluxbox libssh attr sdl2 gtk3 libpixman pkg-config texinfo m4 libssh capstone xorgproto automake libtool python termux-x11-nightly xfce4

git clone https://github.com/lzfse/lzfse.git && cd lzfse && cmake -DCMAKE_INSTALL_PREFIX=/data/data/com.termux/files/usr/ -DCMAKE_POLICY_VERSION_MINIMUM=3.5 && make && make install

The rest of the commands are the same as for Linux, except for ../configure , where the --disable-guest-agent flag needs to be added. This avoids using the getloadavg function, which is not supported on Android (as far as I know). And before running the vm, a graphical environment should be started, using, for example, Termux:X11.

Hey I'm trying to build lzfse but it this happened

CMake Error at CMakeLists.txt:2 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.                                                                                                                      Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.    
  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

Is there a way to fix this?

[TERMZL0ckd0wn]

Ok I've fixed it by changing the cmake_minimum_requirement to VERSION 3.5 in CmakeLists.txt

[Sam2159]

You just need to add the

-DCMAKE_POLICY_VERSION_MINIMUM=3.5

flag in the cmake command. I'll edit my pull request comment to include it.

Is there a way to install img4 and img4tools without root?

[TERMZL0ckd0wn]

img4tool needs libgeneral and it requires root to install

[aspauldingcode]

With termux you can do propt or chroot (rootful)
So the propt way might allow without root

[TERMZL0ckd0wn]

How can I do that?

[Capibarak]

The --disable-guest-agent doesn't work when I need to do the ../configure command

[v1sh4l420]

Hi, I'm a noob. Have you successfully booted it on Android device? If yes then can you make a noob friendly tutorial?

Have you tried compiling img4tool and img4 from source?

[VisualEhrmanntraut]

img4tool should no longer be required

[theoparis]

Won't this break Android compilation outside of Termux (e.g. with the android NDK)?
