I tried to follow the answer posted here https://mathematica.stackexchange.com/a/239308/53728, where the version of Mathematica for Raspberry Pi (armhf) was installed on Android phone.
But still I am getting the error
kirill@localhost:~$ wolfram ERROR: ld.so: object '/support/libdisableselinux.so' from /etc/ld.so.preload cannot be preloaded (wrong ELF class: ELFCLASS64): ignored. /opt/Wolfram/WolframEngine/12.3/SystemFiles/Kernel/Binaries/Linux-ARM/WolframKernel: error while loading shared libraries: libopenblas.so.0: cannot enable executable stack as shared object requires: Permission denied
tried to install open-blas libraries, but I think the problem isn't there
Such a pity: modern phone with 8 powerful cores, there is a free Wolfram Engine available, and I still can't utilize it's power in a proper way.
UPD:
Got managed to downgrade the Mathematica to 11.0 and manually install all libs, but now the error looks like
root@localhost:/opt/Wolfram/WolframEngine/11.0/Executables# wolfram ERROR: ld.so: object '/support/libdisableselinux.so' from /etc/ld.so.preload cannot be preloaded (wrong ELF class: ELFCLASS64): ignored. /opt/Wolfram/WolframEngine/11.0/SystemFiles/Kernel/Binaries/Linux-ARM/WolframKernel: error while loading shared libraries: /opt/Wolfram/WolframEngine/11.0/SystemFiles/Libraries/Linux-ARM/libWolframEngine.so: cannot restore segment prot after reloc: Permission denied
It looks like that I need somehow disable SELinux?
Wolfram recently released Mathematica for Raspberry PI, for ARM64. Finally, you can install it in termux just by executing script, provided here.
This is direct link to script. It will download and install Wolfram engine and Mathematica for ARM64. I managed to install it in termux, and even frontend (Mathematica) works just fine in VNC.
