Hello,

I'm trying to get GuestAddtions running withing CentOS. I'm running Windows7 host and CentOS 6.5 guest. When I issue the mount command, I see:

/dev/sr0 on /media/VBOXADDTIONS_4.3.12_93733 ......etc.

I then run the following command:

sudo sh VBoxLinuxAdditions.run

Everything goes smooth, except I keep getting this error message:

Building the main Guest Additions module [FAILED]

Any help would be appreciated. I'm going through an Intro to Linux course through edX and need to get this going so I can cut and paste between Win and CentOS.

Thanks,

ANdy

We need the rest of the error message. The part that says what went wrong or if it told you to look at a specific log then we need to see that log.

I went back and looked at the error messages and noticed it said the "gcc utility could not be found". I installed gcc and tried to install GAs again, but got another error message. See the attached screenshot (sorry for the screenshot, but I currently can't cut and paste between my host and guest. I'm guessing that will be fixed once I get GAs fixed).

Thanks,

Andy

It tells you what to do to fix this in the error message.

I checked out the log and it repeats this message about 5 times.

***Error: unable to find the sources of your current Linux kernal. Specify KERN_DIR=<directory> and run Make again. Stop.
Creating user for the Guest Additions.
Creating udev rule for the Guest Additions kernel module.

I have no idea how to "run Make". What is it telling me to do exactly?

Thanks,

Andy

Read the image you posted earlier. It tells you to install a missing package and even gives you the command that is needed.

Correct, and I did that (I noted that I installed gcc). But I'm still getting that error message. That's why I re-posted. I'm not sure what step to take next.

Thanks,

Andy

I have no idea what you are reading but the message says that you need to install kernel-devel for your running kernel. It even tells you what to type.

I will quote it for you.

"The missing package can be probably installed with
yum install kernel-devel-2.6.32-431.el6.x86_64"

Can't see the forest for the trees. Don't know how I missed that. I ran that, installed Guest Additions again, and it completed with no
errors this time. Thanks for your help (and patience!).

Took me awhile to get everything installed myself. I want to add that I needed to run "su" then enter my password to be a superuser to get everything to work. I also had to install gcc.

At least we're learning how to do things!
