**Building TDE R14.0.4 on the Raspberry Pi3**
BUILD-TDE.sh has been set up with an option to build TDE on the Raspberry Pi3, with [Sarpi](http://sarpi.fatdog.eu/index.php?p=home) supplied kernel/modules/firmware.
All packages build on Slackware current and 14.2. There have been a number of patches to the source code for gcc 7.x.x, which is used on current.
Build times are as shown, with the number of parallel jobs set at 8 [1], and with one internationalization locale being included. The build was run with the top off the Pi casing, and the cpu temperature generally remained below 80 °C, occasionally peaking at about 82.5 °C. All four cpus ran @ 1200MHz [2].
[1] This may not be the optimum. Based on a sample, builds may be quicker or slower at -j6, some with little difference at -j4, so YMMV. I assume this is because [performance is degraded](https://www.raspberrypi.org/documentation/configuration/config-txt/overclocking.md) at temperatures in excess of 80 °C.
[2] `echo ondemand > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor` if needed.
[3] Avahi-tqt needs libdaemon and avahi packages installed, and these can be built on the Pi from the SlackBuilds.org scripts.
[4] The inkscape build is memory intensive, and using too much swap slows the build. The best compromise is to build it separately and set NUMJOBS to -j3. ( [a] - inkscape-0.91, built with '-j1'/gcc-7.1.0/poppler-0.57 // [b] inkscape 0.92.2 cmake build with '-j3'/gcc-7.2.0/poppler-0.59.).
[5] Both inkscape 0.91 and tdegraphics builds on current with poppler 0.59 failed because of the introduction of a new Object API in poppler 0.58. The tdegraphics build was done with poppler 0.57.
