i'm trying to install ATTO H380 SAS HBA Drivers in CentOS7. but i'm getting Error: Unable to find kernel source code directory. i can not found the exact problem and i not able to resolve this problem.
following is the error message when in run ./install.sh :-
""[root@server lnx_drv_esashba_131]# ./install

ATTO Technology, Inc.
Linux Driver Install Script v2.1

Error: Unable to find kernel source code directory

Kernel source code was expected in /lib/modules/4.17.6-1.el7.elrepo.x86_64/build

If the kernel source code is installed in a different
location, build the driver manually from the src/
directory specifying the correct kernel source directory
on the make command line with the KDIR variable, eg:

# make install KDIR=/usr/src/kernel

Press any key to finish... ""

request you to help in this issue. i'm facing this problem since last 3days. but no one help me in this...

thanks

did you try to install kernel sources?

Yes i installed Kernal with latest one. but still the same problem is coming.

not kernel, but kernel sources. That is a different thing.
