I'm running Debian 8.5 (jessie), but I need cmake 3.5.2 and with apt-get it installed 3.0.2.
So, I downloaded from cmake.org site: wget https://cmake.org/files/v3.6/cmake-3.6.0-rc2-Linux-x86_64.sh
When unpacked I got the files
$ ls -la
total 24

I didn't find any script, make file, or something like that. So, I copied manually bin to /usr/bin,
/man/man1/* to /usr/share/man/man1,
/man/man7/* to /usr/share/man/man7, and
/share/cmake-3.5 to /usr/share/cmake-3.5
But there is not a script to do this automatically?
On the site https://cmake.org/install/, they talk about a ./bootstrap script, but it didn't come on the package.
There are several possible approaches for building CMake from a source tree: If there is no existing CMake installation, a bootstrap script is provided:
Meaning if you got the source tarball, do this. Since you got the binaries you don't need this.
It is however considered bad practice to just copy over installs like this to your /usr tree. For one this will interact with updates to the cmake package from debian. Have you tried installing the cmake packages from sid?

I have a proxmox server so under debian, and I want to mount a remote directory from my Nas Synologies to make backups.
I normally use ssh mounts without any problem.
But this time I have an error that I have never encountered, I can create files, but not delete them.
I find this very strange and I don't see where this can come from
root#proxmox:/mnt/# sshfs user#192.168.0.1:home/data /mnt/dist-folder/ -o reconnect,

This is finally a problem specific to synology.
For the assembly of the file it is absolutely necessary to respect the path by starting with
/homes/<user>home/
So it's give
sshfs user#192.168.0.1:/homes/proxmox/home/data /mnt/dist-folder/
And it's works fine !
It's not the first time that I have an abnormal configuration for this synology tool... AGrrrr
I'm setting up a new website on a new Ubuntu droplet at Digital Ocean. I set this up previously on a different droplet and rsynced the website contents to it. I followed directions I found on the web, but didn't keep detailed-enough notes. I'm just trying to replicate this on the new Droplet. But I've messed up somehow. My knowledge of permissions, etc. is rudimentary :-(
My server has: /var/www/html
This is what I did:
• sudo usermod -a -G www-data [myusername]
• sudo chown -R www-data:www-data /var/www
• sudo chmod -R g+rw /var/www
• sudo chmod -R g+rws /var/www
I then created “/var/www/howardmann.us/public_html” for my website.
(I didn't put the public_html directory in var/www/html. I didn't on my other Droplet. Perhaps I should.)
sudo ls -la /var/www
total 16
drwxrwsr-x 4 www-data www-data 4096 Feb 25 15:43 .
drwxr-xr-x 14 root root 4096 Feb 24 14:27 ..
drwxr-sr-x 3 root www-data 4096 Feb 25 15:43 howardmann.us
drwxrwsr-x 2 www-data www-data 4096 Feb 25 15:42 html
sudo ls -la /var/www/howardmann.us/public_html
total 8
drwxr-sr-x 2 root www-data 4096 Feb 25 15:43 .
drwxr-sr-x 3 root www-data 4096 Feb 25 15:43 ..
Now, excerpts of rsync script (successful to my other Droplet) result from my laptop now:
1.
howardm$ ./deploy.sh
sending incremental file list
rsync: failed to set times on "/var/www/howardmann.us/public_html/.": Operation not permitted (1)
rsync: recv_generator: mkdir "/var/www/howardmann.us/public_html/css" failed: Permission denied (13)
* Skipping any contents from this failed directory *
3.
rsync: mkstemp "/var/www/howardmann.us/public_html/.DS_Store.8zaaQg" failed: Permission denied (13)
Question: How do I fix ownership and permissions on the server directories for 1) proper permissions for a website and 2) permit a rsync deploy?
For comparison, here is the status of my current working web site on the other Droplet:
howardm#howardmann:~$ ls -la /var/www/
total 20
drwxrwxr-x 5 howardm www-data 4096 Mar 5 2016 .
drwxr-xr-x 13 root root 4096 Mar 28 2015 ..
drwxrwxr-x 4 howardm www-data 4096 Jun 8 2016 howardmann.us
drwxrwxr-x 2 howardm www-data 4096 Mar 29 2015 html
Thanks!

Well, I fixed this after reading some more about permissions for a website.
My website folder is titled howardmann.us, which contains a public_html folder with the website contents.
So: /var/www/howardmann.us/public_html. (/var/www also contains a html directory)
I achieved the relevant ownership/permissions with:
sudo chown -R howardm:www-data /var/www/
I'm the owner, and www-data the group.
sudo usermod -a -G www-data [myusersername]
I'm a member of the www-data group
sudo chmod -R 2775 /var/www/
This yields the proper permissions, I believe for a web site.
I made sure the same owner:group applied to all these directories:
ls -l /var/www
total 8
drwxr-sr-x 3 howardm www-data 4096 Feb 26 19:23 howardmann.us
drwxrwsr-x 2 howardm www-data 4096 Feb 25 15:42 html
ls -l /var/www/howardmann.us
total 4
drwxr-xr-x 11 howardm www-data 4096 Feb 5 2017 public_html
Now rsync works without errors.
If anyone believes these ownership/permissions for a website are (substantially) improper, please comment.

I downloaded nagiosql_320.tar.gz and installed NagiosQL. When I click on check configuration file, it shows error as:
Cannot find the Nagios binary or no execute permissions!
I created symlink as below for nagios binary with following permission.
lrwxrwxrwx 1 root root 28 Jul 5 16:07 /usr/sbin/nagios -> /usr/local/nagios/bin/nagios
-rwxr-x--- 1 nagios apache 692624 Jun 27 14:40 /usr/local/nagios/bin/nagios
How can I correct the error?
chmod +x /usr/local/nagios/bin/nagios and try again
I downloaded the RALINK driver from their web site
untar -xvf rtl*
and then i ran "make" in it. google search suggested "kernel-devel"
needed to be installed.
i installed the kernel-devel package but i still get this error
make: *** /lib/modules/2.6.32-279.el6.x86_64/build: No such file or directory. Stop.
when i check to see if that file exists..
i cd into /lib/modules/2.6.32-279.el6.x86_64/
i believe this error happens right after "make" command tries to execute this command
make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/2.6.32-279.el6.x86_64/build M=/home/a/Desktop/3/rtl8712_8188_8191_8192SU_usb_linux_v2.6.6.0.20120405 modules
and it's there it is called "build"
so why is it saying no such file or directory ?
**EDIT**
If your problem is like the one I was having (see below), it seems the kernel development package isn't installed.
Try:
yum install kernel-devel
Original Message
I am having the same problem. But, interestingly, when I ls-l on the parent directory to the "missing directory" (so, ls -l /lib/modules/2.6.32-431.el6.x86_64/) it shows that build is a broken link pointing to /usr/src/kernels/2.6.32-431.el6.x86_64, but /usr/src/kernels/ is empty.
So, I don't know if this is much help, but hopefully it gives someone else a better idea of what's wrong.

Notice that the "source" link is also broken because it points to build.
cd /lib/modules/2.6.32-431.el6.x86_64
sudo rm build
sudo ln -s ../../../usr/src/kernels/2.6.32-431.29.2.el6.x86_64/ build
The above commands fixed the issue for me
But basically you must be able to use any version of 2.6.32* directory in the last command.
Thanks to Nighthawk663.
I have the same problem in ./configure --with-linux=/lib/modules/uname -r/build/. It says "not a file..." too.
Reason:
The kernel head files are missing for the current kernel.
How I solved it:
find current kernel: uname -r
yum install kernel-devel-$(uname -r)
you may not find it...
just google that version of kernel-devel-... download the rpm file, and do
rpm -i kernel-devel-xxxx.rpm
Then it works for me!
/usr/lib/modules/your-kernel-edition/build is a link file.
the link file exists. but the target file might not exists. So It is ok to see the link file, but the folder can not be changed into it (cd).
Similar Example on fedora 29.
lrwxrwxrwx. 1 root root 40 Oct 21 07:38 /usr/lib/modules/4.18.16-300.fc29.x86_64/build -> /usr/src/kernels/4.18.16-300.fc29.x86_64
Just install kernel-devel.
Example.
sudo dnf install kernel-devel-$(uname -r)
Because the link is not with your kernel version.
Delete the wrong link.
$ rm build`
Use $ uname -r to check the kernel version
Build new link with your kernel version.
$ ln -s ../../../usr/src/kernels/($(uname -r)/ build
Done
when i install netbeans it gives me the option to select the java environment, i have 3 options, the oracle java and these two (java-1.7.0-openjdk-i386 and java-7-openjdk-i386). what is the difference between these two?The os if ubuntu.
The two OpenJDK are same. However OpenJDK is slightly different from Oracle JDK. Read this post for more clarification.
The reason why you are getting two options for OpenJDK is PROBABLY that you have two copies of OpenJDK installed (or two different references to the same directory on your system.)
For further investigation, try to ls -lh /usr/lib/jvm. The /usr/lib/jvm is usually the directory where Java gets installed. Check if one of them is a symbolic link. Also, check in netbeans the location of the two JDK and see if in fact you have two versions or references of Java on the system.
For example, here is the output of ls -lh on my system:
ls -lh

As you can see java-1.6.0-openjdk-i386 is just a symbolic link/reference to another directory named java-6-openjdk-i386
You installed it twice
From openjdk, following instructions from here
sudo apt-get install openjdk-7-jdk
From Stackoverflow, following instructions from here
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
Would recommend the second one and remvong the first one by typing
sudo apt-get remove openjdk-7-jdk.
