Problem installing asterik


I have a problem to install asterisk.
When I do “make install” under asterisk I have the following message
/usr/bin/ld: cannot open output file asterisk: Is a directory
collect2: ld returned 1 exit status
make: *** [asterisk] Erreur 1
[root@sip asterisk]# CD /USR/sbin
bash: CD: command not found

What is the problem ? How to solve it ?

what kernel do you have? try just the word “make” also is this when you are trying to install some drivers possibly zaptel?
