Installing touchegg in a proot-distro alias of Debian in Termux

[b9Joker108]

Hi

In Termux , I am endeavouring to launch a XFCE4 GUI, in my proot-distro alias of Debian, with Termux-x11. I have done so, but on my tablet, it isn't very touch friendly. Can I install touchegg in Debian somehow?

Any assistance greatly appreciated.

Thanking you in anticipation Beauford

This is how far I have got so far, and it has been an involved process:

(base) root@localhost:/root/touchegg/touchegg-2.0.17/build # cmake ..

  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

Hi!

I'm not familiar with Termux, and I'm not sure if Touchégg will work on Android (I have never test it), but the error is:

CMake Error at /data/data/com.termux/files/usr/share/cmake-3.29/Modules/CMakeDetermineSystem.cmake:35 (file):
  file failed to open for reading (No such file or directory):

On my Fedora install, I the file can be found at /usr/share/cmake/Modules/CMakeDetermineSystem.cmake (and inside some Flatpak SDKs).

You can try to check if the file is present in a different path:

$ find / -name "CMakeDetermineSystem.cmake" 2> /dev/null

And create a symlink or try to copy it from a regular Linux distro and see if you are lucky enough to make it work.

I'm afraid I won't be able to help you with this issue as I don't have a way to run Termux.

Thank you so much for your response. As it turns out, I don't require Touchégg, as Termux-X11 has built-in functionality to enable touchscreen functionality for the GUI. This works for both launching the GUI of the Termux host environment, and the GUI of chroots. I didn't know this when I began prospecting the Touchégg solution. I learnt much from trying to get Touchégg working in my Debian chroot, so the time and endeavour wasn't a waste. Thank you so much for your code.
