According to their wiki Termux does not do chroot to present a standard fs to the user. There is a script to do it called termux-chroot.

Re: [Chicken-users] Is Android not unix?
I don't know how UserLand works, but there's no containerization in Termux. It's just an terminal emulator with its own package manager with quite a few packeges like emacs, gnu make and clang. So building CHICKEN is pretty straight forward. K.

Re: [Chicken-users] Is Android not unix?
I had no problem compiling chicken in termux (though occasionally there are linkage warnings on android6). My understanding is that android is basically stripped down linux with a java overlord layer. No compatibility layer necessary. This is borne out by my current work on cross-system randomness - it behaves exactly like a linux machine, with the same syscalls, etc. (Which reminds me. If anyone has a bsd box i can get a login for, it would be much appreciated. Im trying to do a chicken wrapper for true randomness using sidechannel effects... so something that looks platform independent.) -elf On 26 November 2018 5:15:03 GMT+02:00, Matt Welland wrote: >Isn't Termux similar to UserLand - a compatibility layer of sorts >similar to LXC or LXD?

Re: [Chicken-users] Is Android not unix?
Isn't Termux similar to UserLand - a compatibility layer of sorts similar to LXC or LXD? If so, I would not be surprised to see incompatibilities. I had to do several hacks to get IUP working on UserLand.

Thanks for following up on this, Thomas! tweetnacl 1.4.1 now works ootb on Termux. K.

If there is some other feature identifier I should use that would indicate the system likely supports /dev/random, please let me know so I can adapt the tweetnacl code. Anyway, as a workaround to get tweetnacl running, you can simply do (current-entropy-port (open-input-file "/dev/random")) by hand.

[Chicken-users] Is Android not unix?
Hi guys, I was trying tweetnacl on Termux on Android 9 and ran into this problem: u0_a191@localhost ~/p/chicken-5.0.0> csi -R tweetnacl -p '(make-symmetric-sign-key)' Error: (read-u8vector) bad argument type - not a port: #f This happens because tweetnacl creates its current-entropy-port using cond-expand with unix, windows or else, the latter which is yielding the #f error above. I found this surprising as I'd expect Android to be unix. As I'm sure you know, it isn't: csi -p '(cond-expand (unix 1))' Error: during expansion of (cond-expand ...) - no matching clause in `cond-expand' form: unix u0_a191@localhost ~/p/chicken-5.0.0> csi -p '(cond-expand ((or android unix) 1))' 1 But tweetnacl isn't much use without current-entropy-port, and I hove its /dev/random requirement: u0_a191@localhost ~/p/chicken-5.0.0> dd if=/dev/random bs=1 count=12 ^/dev/null |xxd -p 44ca8634752db3243ac222f0 So, my questions: 1. Is Android non-unix intentionally? 2. Could tweetnacl cond-expand with (or unix android) so it works out-of-the-box on Android?
