Linux distributions come with "packager managers" that let you install software that they offer. Most Linux distributions offer curl and libcurl to be installed if they are not installed by default.
aptis a tool to install prebuilt packages on Debian Linux and Ubuntu Linux distributions and derivatives.
To install the curl command-line tool, you usually just
apt install curl
…and that then makes sure the dependencies are installed and usually libcurl is then also installed as an individual package.
If you want to build applications against libcurl, you need a development package installed to get the include headers and some additional documentation, etc. You can then select a libcurl with the TLS backend you prefer:
apt install libcurl4-openssl-dev
apt install libcurl4-nss-dev
apt install libcurl4-gnutls-dev
With Redhat Linux and CentOS Linux derivatives, you use
yumto install packages. Install the command-line tool with:
yum install curl
You install the libcurl development package (with include files and some docs, etc.) with this:
yum install libcurl-devel
Nix is a package manager default to the NixOS distribution, but it can also be used on any Linux distribution.
In order to install command-line tool:
nix-env -i curl
curl is located in the core repository of Arch Linux. This means it should be installed automatically if you follow the normal installation procedure.
If curl is not installed, Arch Linux uses
pacmanto install packages:
pacman -S curl
With SUSE Linux and openSUSE Linux you use
zypperto install install packages. To install the curl command-line utility:
zypper install curl
In order to install the libcurl development package you run:
zypper install libcurl-devel
These versions of SUSE/openSUSE Linux are immutable OSes and have a read only root file system, to install packages you would use
zypper. To install the curl command-line utility:
transactional-update pkg install curl
And to install the libcurl development package:
transactional-update pkg install libcurl-devel
