 Post subject: Arrow keys in Singular terminal: [[A^[[B^[[D^[[C
PostPosted: Thu Nov 06, 2014 11:41 am 
I have recently installed Singular 4.0.1. However now the arrow keys in terminal return [[A^[[B^[[D^[[C.
This only occurs in Singular 4.0.1 and not in Singular 3 - 1 -5 nor in the terminal when Singular 4.0.1 is running.
How can I fix this?

Please check the build option of your Singular version
(either by starting it as Singular -v or via system("with"); from within Singular).
In the 3rd line it should mention "static readline" and not "fgets":
If fgets is mentioned, please tell us the exact version and OS your are using:
Singular needs to be rebuild to fix it.
On the other side, if readline is mentioned, your terminal type is not recognized
(try system ("getenv","TERM");) - it depends on your OS/terminal etc.

Just checked: the official binaries are built with readline.
For you it means that during the configure readline library or include files are not found:
please install them via
"yum install readline-devel -y"
and run ./configure and make again.
