I just installed sagemath binary, latest stable version 9.4 on my Linux VBox. I normally install sagemath using the Linux Manjaro package manager, but it only see 9.3 now. That is why I downloaded the binary from https://www.sagemath.org/download-linux.html (downloaded the 64 bit version).
Uninstalled 9.3 from my box.
Now I started to use sage 9.4 binary, and set the path, and started it. Everything looks OK. I am able to use fricas and maxima integrate, but can no longer use giac. Even though all of these are installed on same Linux I am using, and I was able to use giac from 9.3. But not from 9.4. Here is a MWE
>which giac
/bin/giac
>giac --version
// Using locale /usr/share/locale/
// en_US.utf8
// /usr/share/locale/
// giac
// UTF-8
// Maximum number of parallel threads 2
// (c) 2001, 2021 B. Parisse & others
1.7.0
