how to install unixodbc on linux

I am trying to install unixodbc on linux (clean install of ubuntu 20), but the directions here are not working for me. When I get the step to ./configure , I get an error saying "configure: error: odbc_config not found (required for unixODBC build)".
Given that this is a popular package and the instructions on the main website don't work, I'm wondering if someone in that community could help me install it?
I tried installing it directly from a .deb file which appeared to work with 0 exit status, but I am still getting an error when I try to run odbc_config, which is how they say to verify the installation. And which unixodbc returns nothing.
Any help installing this package on linux would be greatly appreciated!
Note: On mac, brew install unixodbc works just fine. But I am running into problems when using the compiled binaries from that installation on a linux machine -- it is giving me a mysterious file not found error when I try to reference it, even though it is there, so I believe I need to compile it on linux in order to get it to work.
EDIT: I tried installing from source, but then I got a different error: libpq library version = 9.2 is required. Is there any way to install this package on ubuntu without having to set all kinds of special flags?
EDIT2: I was able to get the installation process to complete after installing libpq-dev.

Trouble met when installing PCL on Ubuntu 18.04

I have trouble in installing PCL 1.9 on my Ubuntu 18.04. Could anybody please help? Really thanks.
I already tried as many tutorials on the Internet. However they both won't work.
When trying to add ppa source and use apt/apt-get to install libpcl-all, it seems that the source doesn't work for ubuntu18.
When I was trying to build the PCL myself, on Ubuntu 18.04, it has lots of dependencies problems. Many tutorials say that using apt to install the dependencies, however some libraries are not available in apt.
There are some people suggesting to use apt install libpcl-dev. Although there is no errors in installation, when I tried to compile an example code, it still doesn't work.
Using pcl-trunk might be your best choice.
git clone https://github.com/PointCloudLibrary/pcl pcl-trunk
cd pcl-trunk && mkdir build && cd build
cmake ..
make
sudo make install

Compiling module using SDK throws warning message: libelf-dev not found

We have customized intel core-i7-64 machine and we developed Yocto Image and SDK for the hardware.
After sourcing the environment script and running "make modules_prepare", I get the following warning:
Makefile:956: "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel"
The same error happens when I compile out of tree modules. How can i remove this error. What all packages should we need to add to avoid this.
Install libelf-dev and elfutils package. If you are using ubuntu or any debian variant then use the following command to install them.
sudo apt install libelf-dev

Path to Node.js Installation in Ubuntu

I am new to Ubuntu (linux).
I installed node.js for a project.
Recently I am getting this error on npm install.
Error: "pre" versions of node cannot be installed, use the --nodedir flag instead
I found a stack link below as
Node pre error
Under the solution it asks for the directory where node.js is installed and currently i am clueless where the nodejs is installed.
Please help me on how can I locate the directory where node.js is installed.
Quick explanation
You have a version with -pre. Get rid of it and put the latest stable version from nodejs.org.
You can use which to locate a command. For your case, type which nodejs.
EDIT: The answer from your link is referring to the path of node source code, not the nodejs binary.
On Ubuntu, most software can be installed from the built-in repositories. This updates it for you (even if it's sometimes a bit outdated).
To install the stable version the Ubuntu way, install the nodejs-legacy package (after uninstalling your version):
sudo apt install nodejs-legacy
To use the latest, refer to https://askubuntu.com/a/663052/438156 (my answer), or https://askubuntu.com/a/711976/438156 (bit more involved, more the Ubuntu way).

error when trying to install libtmcg "configure: error: libgmp >= 4.1 is needed"

I've tried installing different libgmp's from ubuntu app center and I tried installing it manually from http://gmplib.org/#DOWNLOAD but I can't get this to configure it's an old library and I'm trying to run it on the latest version of ubuntu but I didn't think I'd have problems but I'm new to trying to use libraries like this any help would be greatly appreciated.
I've had these kind of errors installing dependencies before, and I realized that you must to force the installation of such pack having it... you didn't mention the version of your Ubuntu, so I'm assuming you're working with 12.10. But if not you always can look up for the version you are running on.
Just download the pack from here, of course, depending on your architecture, and after that run sudo apt-get -f install in order to force the installation of broken packs.
