rvm install ree complaining about readline on Ubuntu - rvm

I'm trying to install ree-1.8.7 on Ubuntu 11.10, but I get the following:
$ rvm install ree-1.8.7
$ ...
$ ERROR: Error running './installer -a $HOME/.rvm/rubies/ree-1.8.7-2011.03 --dont-install-useful-gems -c --with-readline-dir=$HOME/.rvm/usr', please read $HOME/.rvm/log/ree-1.8.7-2011.03/install.log
$ ERROR: There has been an error while trying to run the ree installer. Halting installation.
If I check the install.log file as suggested, it says that:
GNU Readline development headers... not found
...
Please run apt-get install libreadline5-dev as root
That didn't work because the package is no longer available, so I finally found out about using libreadline from a rvm package. So I install it and run the install again:
$ rvm pkg install readline
$ rvm install ree-1.8.7 -C --with-readline-dir=$rvm_path/usr
I still get the same error even if I run rvm remove ree beforehand.
I'm stuck, what can I do?
UPDATE: I'm still stuck, but I found something that might be useful for others with a similar issue even though it didn't work for me. From the RVM REE page:
NOTE: on any OS, if installation of REE fails and the output file reports missing readline-devel, zlib-devel, and openssl-devel headers AND you are sure that you have read the packages install instructions - or you are otherwise positive that you have the necessary packages installed in a known location - check your PATH environment variable to make sure something like "/usr/lib" is NOT present. See this REE issue for more information. If you don't want to change your PATH variable then this patch fixes the issue in REE 2010.02
I checked my path and all I had that contained /usr/lib was /usr/lib/lightdm/lightdm. My full $PATH is this: bash: /home/michel/.rvm/gems/ruby-1.9.3-p0/bin:/home/michel/.rvm/gems/ruby-1.9.3-p0#global/bin:/home/michel/.rvm/rubies/ruby-1.9.3-p0/bin:/home/michel/.rvm/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games: No such file or directory.

I finally got it working by running this line:
rvm install ree --with-readline-dir=$rvm_path/usr --with-iconv-dir=$rvm_path/usr --with-zlib-dir=$rvm_path/usr --with-openssl-dir=$rvm_path/usr
Running only rvm install ree --with-readline-dir=$rvm_path/usr didn't work, so maybe they all need to be run at the same time.
Note that I ran the following commands some time before succeeding:
rvm head update; rvm reload;
# remove any file from previous failed installations
rvm remove ree
# as suggested in a comment on the question
sudo apt-get install libreadline6-dev
I'm not sure if the libreadline6-dev was necessary, but maybe and it's worth a try if you're having trouble.

How do I install an older ethtool version on a machine?

I need to test if some firmware is compatible with older ethtool versions.
The machine I am using currently have ethtool version 5.16, but I need to install ethtool version 5.13
I got the compressed file from https://mirrors.edge.kernel.org/pub/software/network/ethtool/ and have used tar -zxvf https... to extract the files. This extracts a directory with the contents shown below:
After reading the INSTALL file, I ran ./configure but it gave me the following error: configure: error: The pkg-config script could not be found or is too old. Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config
This meant that I could not run make or make install and thus am stuck.
After speaking to colleagues, the solution was found:
apt-get install -y pkg-config. Thereafter the following package was also needed: apt-get install -y libmnl-dev
Simple installed it with ./configure, make and make install and saw the ethtool version was as desired.

Ubuntu Cannot reinstall coreutils

I deleted the usr/bin/env directory/file in my Ubuntu16.04 by mistake. Everytime i try to reinstall coreutils with this command:
sudo apt-get install --reinstall coreutils, i get this error:
Reinstallation of coreutils is not possible, it cannot be downloaded.
I can't use npm because it needs that directory.
Please help.
I solved this by manually getting the env file from the coreutils package i downloaded from the Ubuntu site and replacing where i deleted it.

Not able to install mod_perl module on the server

In my site I am getting an error : an error occurred while processing this directive
It was working fine before moving to the new server. So when I checked I found that mod_perl module is missing. So I tried to install it by downloading the module to the server and then tried to run using Perl Makefile.pl but it was asking for apache src and I was not able to find it. I can see /usr/bin/apache/ folder but no source file inside the folder.
So I tried to install the module from Cpanel but I got the following error:
The C compiler is not functional and auto repair failed. Perl module installs require a working C compiler. Please repair the C compiler and try again.
Please let me know how to install it as I have tried most of the cases searching the net.
Thanks in advance
It's probably best to use your distro's packaging system to install mod_perl, especially, if apache is installed from a package too.
Yum based systems:
yum install mod_perl
Deb based systems
apt-get install mod_perl
you may need to enable the module using a2enmod
Mostly gcc is either corrupted or not present on your system. Please try to re/install gcc on your system
sudo apt-get update
sudo apt-get install build-essential
On Redhat:
yum update
yum install devtoolset-2-toolchain
It seems like a problem with your installation of gcc. You're using CloudLinux, so you should use yum to reinstall gcc.
$ sudo -i yum install gcc
But you don't need gcc if you install the pre-build packages.
$ sudo -i yum install mod_perl
Either way, you're going to need to get to grips with package installation for your system - and for that you're going to need root access.

cmake not working, could not exec qmake

I am using Ubuntu 14.04. I'm trying to install a program which requires cmake. When I run cmake src/ I get:
qmake: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qmake': No such file or directory
What am I doing wrong?
Does the trick:
sudo apt-get install qt4-qmake
You do not need to install half a gigabyte of qt sdk!
I read on another post that the problem has something to do with CMake not being able to find Qt4 qmake.
However in my case, it was simply a matter of not having qt4-qmake. This solved it (but weighs a heavy 440MB):
sudo apt-get install qt-sdk
For newer versions of Ubuntu, if you have only installed version 5 of the Qt Framework, you may get this error. If you want to use Qt version 5 by default, then you should run the following command to fix the error:
sudo apt install qt5-default
You need the qt dependences:
sudo apt-get install qt4-qmake libqt4-dev
as it says in docs: https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#debian--ubuntu
sudo apt-get update
sudo apt-get install qt5-default libqt5webkit5-dev gstreamer1.0-plugins-base gstreamer1.0-tools gstreamer1.0-x
works for me in Ubuntu 18.04
You can use QtCreator to compile the cmake project too. This is only advantageous over the accepted answer if you already have QtCreator installed, I notice you are using a qmake project so this might be likely.
The main advantage of this is that qt creator will be configured to use the qmake tool without the need to install the command line configured version of qmake.
Incidentally, I get this error if I try to run the qmake executable bundled with QtCreator on the command line.

Passenger/Apache missing gcc/zlib-devel on AWS/CENTOS

I am trying to install Passenger for Apache on an AWS instance running CENTOS. When I try to install it, it tells me:
GNU C++ compiler... not found
Zlib development headers... not found
These have both been installed (yum install gcc zlib-devel) and are at the latest version. gcc -v says that it's at 4.6.2.
I have seen similar questions where the accepted answer was to run
mount -o remount,rw,exec,nosuid /tmp
This returns the following:
mount: can't find /tmp in /etc/fstab or /etc/mtab
I have tried changing the permissions on the /tmp directory (it does exist, just doesn't appear to be mounted) with chmod 777 /tmp, but this did not allow the Passenger install to see the two packages.
Could someone please help me with this? I'm not sure what else to do at this point.
I couldn't solve the issue above, but I managed to install anyway by adding EPEL, then installing mod_passenger through yum:
rpm -Uvh http://ftp.linux.ncsu.edu/pub/epel/6/i386/epel-release-6-8.noarch.rpm
yum install mod_passenger
