I recently bought a Raspberry Pi 3 with Raspbian NOOB preconfigured on an SD card. I had the need to install the TLS extension. It was suggested in comp.lang.tcl to use [Undroidwish]. Below are the steps I took to build [Undroidwish] (there was a bit of trial and error but I hope I remembered correctly and didn't miss something!). First upgrade your Raspbian NOOB with sudo apt-get install upgrade sudo apt-get install dist-upgrade With advice from [chw], I installed the following packages with sudo apt-get install <package> bc libx11-dev libusb-dev libudev-dev freeglut3-dev librsvg2-dev libdbus-1-dev libaugeas-dev libasound2-dev zip Download the latest Source code (tarball) from the [AndroWish] Downloads page [http://www.androwish.org/download/index.html] and place it in say /usr/local/src. Then uncompress and untar the file: tar -xvzf androwish-a05b615f58.tar.gz Created a directory outside the source tree, I named mine undroid mkdir /usr/local/src/undroid Change directory to undroid cd /usr/local/src/undroid Enter the following command and hopefully everything builds without an issue: /usr/local/src/androwish-a05b615f58/undroid/build-vanilla-generic.sh So hopefully all the packages build and two files are created with all the packages wrapped up and placed in the current directory. The files are vanillatclsh and vanillawish. The directory should look like this : raspberrypi:/usr/local/src/undroid# ls 3dcanvas curl libdmtx sdl2tk tbcload tclkit tclx tkpath tkvnc v4l2 zint assets dbus-intf libressl snack tcl tcludp tdom tktable tls vanillatclsh zlib assets.zip dbus-tcl Memchan tassets tcl-augeas tcluvc tkhtml tktray trf vanillawish build.log itk opt tassets.zip TclCurl tclvfs tkimg tktreectrl trofs ZBar Now test it out raspberrypi:/usr/local/src/undroid# ./vanillatclsh % info patchlevel 8.6.6 % package require tls 1.6.7 A similar approach can be used to generate [undroidwish] which has the added benefit to not require an X server and X11 runtime environment on the Raspberry due to support of the Raspberry frame buffer. /usr/local/src/androwish..../undroid/build-undroidwish-generic.sh Current releases of the AndroWish source tree (>= 2019) turn on the "RPI" SDL2 video driver which uses the VideoCore libraries below /opt/vc for driving the frame buffer. This allows to run it with the minimal Raspbian images for Debian versions 8 (jessie), 9 (stretch), and 10 (buster) without requiring installation of additional packages. There's a ready made [undroidwish] for Raspbian as of 2020-01-20 in http://www.ch-werner.de/AndroWish/undroidwish-raspi which has been successfully tested with an HDMI monitor and with the official Raspberry 7" touch display. Support for /dev/input (evdev based) capacitive and resistive touch screens is built into the SDL2 layer. While capacitive touch screens work OOTB, resistive ones require calibration, see the https://www.androwish.org/home/dir?name=assets/touchcal0.1%|%touchcal package%|% and its use in the https://www.androwish.org/home/artifact/8c4639b2aea261b4%|%vncviewer demo%|%. ---- '''[lai] - 2020-02-05 02:42:39''' I've installed tls 1.6.7 on the RasPi 3 this way: - sudo apt-get install tcl-dev libssl-dev - download tls 1.6.7 from sourceforge - to install tls 1.6.7: ./configure; sudo make; sudo make install <<categories>> AndroWish
