Thanks to all!

Abdelhakim: That script mentions ndk, which makes it look to me like a cross-compiler for building apk applications from a Linux host. I want to compile on the tablet itself, and call the program from the Termux command line.

Bradley: Sorry to hear that. But I'm not actually compiling on Android, I'm trying to compile on Termux, which is a Unix-like (not Android-like) environment.

Vincent: I'm not in any way wedded to Termux. I'll take a look at GNURoot.

Alexander: Sounds great! I'll look forward to hearing from you again this evening.

Again: Thanks to all!

Hi Phil, dear list,

In the past I have successfully built Gambit 4.8.5 for Android /Termux.

You have to say ($PREFIX is predefined by Termux) :

CONFIG_SHELL=$PREFIX/bin/sh . /configure ...

IIRC. Also you have to fix the shebang path in 2 more scripts for installation to work. I am currently on my way to work, but can look them up in the evening.

Good luck and best regards,

Alexander

I recently purchased an Android tablet, a Lenovo TAB2 A10; it uses a Qualcomm Snapdragon 210 ARM7 32-bit processor with 2GB RAM. I installed the Termux program from the Google Play Store, which provides a unix-like command-line environment with BusyBox and a host of programs including gcc. Termux is rather non-standard in its directory structure, with the root of the system at /data/data/com.termux/files (call that directory TERMUX) and high-level subdirectories $TERMUX/home for the default user u0_a111 and $TERMUX/usr where you will find bin, etc, include, lib, libexec, share, src, tmp and var. All of the normal unix executables are in $TERMUX/usr/bin, even those that normally reside in /bin.

I would like to have a Scheme REPL on my tablet. Can Gambit Scheme be compiled on my machine? What configuration options will I need to supply? What problems should I expect? Has anybody successfully compiled Gambit Scheme in this environment? I've never compiled Gambit Scheme before, and I'm not an accomplished C programmer, so please keep things simple.

Here's an example of the kind of problems I expect. I downloaded Gambit 4.7 and did tar -zxvf. The I ran ./configure, but had an error because /bin/sh isn't in /bin/sh. I edited the shebang line on ./configure and ran it again, and got an error "cannot run /bin/sh ./config.sub".

I expect some pain. . . .

Many thanks,

Phil
