Package: yacas Version: 1.3.6-1 Severity: important Dear Maintainer,
After installing the yacas package, I ran it in order to try out some simple examples from the tutorial. However, nothing worked as expected. The main reason for this seems to be due to the program not finding its initialization file, 'yacasinit.ys'. Here is a sample session showing the incorrect behavior: $ yacas yacasinit.ys(1) : File not found yacasinit.ys(1) : File not found yacasinit.ys(1) : File not found This is Yacas version '1.3.6'.

To see example commands, keep typing Example(); In> 1+1 CommandLine(1) : Error parsing expression, near token + In> N(Sin(1),20) Out> N(Sin(1),20); In> Exit() Out> True; Quitting... $ To diagnose the problem, I ran the program under strace and discovered it was trying to open the file "/usr/share/yacas/scripts/yacasinit.ys". However, that file is actually installed as "/usr/share/yacas/yacasinit.ys". As a workaround, I added a symlink: $ sudo ln -s . /usr/share/yacas/scripts After that, the program worked as normal. Here are those example inputs and outputs with the workaround in place: In> 1+1 Out> 2 In> N(Sin(1),20) Out> 0.84147098480789650665 In> Exit() Out> True Quitting... -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (900, 'testing'), (800, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.3.0-1-amd64 (SMP w/6 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages yacas depends on: ii gnuplot 4.6.6-3 ii google-chrome-stable [www-browser] 48.0.2564.116-1 ii iceweasel [www-browser] 44.0.2-1 ii libc6 2.21-9 ii libgcc1 1:5.3.1-8 ii libstdc++6 5.3.1-8 ii w3m [www-browser] 0.5.3-26 ii yacas-doc 1.3.6-1 yacas recommends no packages.
