Looking to build the latest cURL installation from the source?
cURL shipped with the OS may not be up-to-date, and if you need the latest version for a particular requirement, then you need to build from the source.
Just, I was testing HTTP/3 using cURL with the default shipped version on CentOS, but that didn’t work.
[root@lab ~]# curl --version
curl 7.29.0 (x86_64-redhat-linux-gnu) libcurl/7.29.0 NSS/3.44 zlib/1.2.7 libidn/1.28 libssh2/1.8.0
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz unix-sockets
[root@lab ~]#
However, the latest cURL version (7.67) supports HTTP/3. So, I had only one option – build from the source. This is just one example; you may have some other requirement.
The following example is for 7.67 (latest as I write). But the procedure remains the same for any other version.
Here is how to cURL Installation work
Let’s get the required dependencies installed.
Update the system. Though this is optional, I prefer doing so. I always have up-to-date installed packages.
yum update -y
Installing the required packages
yum install wget gcc openssl-devel -y
Download the latest cURL source – you can refer to their official download page to know the latest version.
wget https://curl.haxx.se/download/curl-7.67.0.tar.gz
Extract the downloaded gz file.
gunzip -c curl-7.67.0.tar.gz | tar xvf
It would create a new folder on the present working directory.
Building cURL
Once you’ve downloaded and extracted the latest cURL, its time to build them.
Go inside the newly created folder after extraction
cd curl-7.67.0
Configure with SSL as below
./configure --with-ssl
You will see output something like below.
