It's supposedly a Linux environment into which one can install standard development tools etc.

Yes, that's current terminal emulator in my android devices. We can contribute just by making pull request here: https://github.com/termux/termux-packages/pulls

FPC for ARM works correctly with termux, but the program to generate fpc.cfg does not, requiring some manual configuration to get it to find the included units, etc.

Thanks both for that. I've got an Intel-based tablet here and might have a play.

I've copied over a preinstalled x86_64 compiler etc. from my desktop system to a tablet and individual programs appear to be executable, which is quite an achievement in itself: eat your heart out, Dynabook :-)

I agree that fpcmkcfg looks to be a bit of a problem. On one occasion it deigned to tell me that there was an fpcmake (?) problem, I'll see if I can get a better grip on it.

Basic operation of the the text IDE appeared OK, as did a program written using a text-mode dialogue editor (Dialedit3b); however I suspect that an abrupt switch from landscape to portrait mode is likely to be a problem.

Apparently requires libpthread, which in our case we have not got.

Is this really needed, and since this program should be usable as a system's "sanity check" is there any way to improve the error reporting?
