Howto install on android Termux?

[v217]

1. Did anybody manage to install plan9port on Termux? Or at least the rc shell?

2. Is there an easy way to just compile one cmd (the rc shell)?

Thanks!

Yes, `cd src/cmd/rc; mk install`. however if you're interested only in plan9 shell commands, it should easier for you to install from [9base](https://tools.suckless.org/9base/).

@wgrr @aksr Thanks for the links, there seems to exist a convenient way to get a chrooted ubuntu environment in Termux, so I will try this first. I thought somebody has certainly ported a rc version to android.

@wgrr Is there an easy way to build just mk?

[mirtchovski]

see dist/buildmk in p9p. it's the first thing INSTALL does

I just tried 9base-6, then plan9port-master, both in main termux, not chrooted. [9base-6 (which is old now) failed with missing header.] p9p failed with this:

* Running on Linux: checking for NPTL...

I'm always surprised when ulong is missing.

@v217: Thanks for the chroot link. I like that they suggest VNC for GUI; the RealVNC viewer for Android has good 3-button support. I'll be happy if sam & acme work. :)

EDIT: I lied and I missed a bit. Only that test failed, it started building mk afterward, but I didn't want to see how many type errors would appear, so I cancelled the build.

I forgot to paste this:

* Compiler version:
        clang version 9.0.0 (tags/RELEASE_900/final)

I changed my mind (see edit), but ran into this missing getcallerpc error, which is more serious than a missing header. I imagine it will block compilation in the Ubuntu root on my tablet, too.

>>> cd /data/data/com.termux/files/home/p9p/src/lib9
9c getcallerpc-aarch64 unknown.c
clang-9: error: no such file or directory: 'getcallerpc-aarch64'
clang-9: error: no such file or directory: 'unknown.c'
clang-9: error: no input files
>>> cd /data/data/com.termux/files/home/p9p/src/lib9
9a getcallerpc-aarch64 unknown.s
usage: 9a file.s

EDIT: Looks like yet another name translation is required. It's looking for aarch64 when the file is named arm64.
src/lib9/getcallerpc-arm64.c

And then I got the same error as 9base:

>>> cd /data/data/com.termux/files/home/p9p/src/lib9
9c readcons.c
readcons.c:5:10: fatal error: 'sys/termios.h' file not found
#include <sys/termios.h>
         ^~~~~~~~~~~~~~~

Not sure there's much to do here. Termux is not a supported build platform. It's clearly very incomplete.

[eekee]

Fair enough. I had to stop using my tablet for ergonomic issues, TBH. If I take it up again, I could go for one of the complete chroots.

[v217]

rc is now available on Termux!
