Upgrade libpng to 1.6

Question

Good afternoon,

I am have an AWS EC2 Instance running centos and PHP 7.4.28. The libpng version included is 1.5.13. There are several bugs in this version, and would like to upgrade to the latest release of 1.6.37. However, yum update cannot find any packages to update.

Is there any plan to make 1.6.37 available?

Thanks,
Ben

Hey! Thank you for reaching out with your question. 
     
    On a running CentOS system with PHP 7.4 and libpng1.5 already configured, you can use the following steps to upgrade to libpng1.6-
     
    1. Install wget to your instance for internet package download capability by running - $ sudo yum install wget
    2. Ensure you have gcc installed to have an available path compiler for packages - $ yum install gcc
    3. Install libpng1.6 to your instance with the following steps
    $ wget https://download.sourceforge.net/libpng/libpng-1.6.37.tar.gz
    $ tar xvfz libpng-1.6.37.tar.gz
    $ cd libpng-1.6.37
    $ ./configure --prefix=/usr/local/libpng/1_6_37
     
    NOTICE- If you receive a "lib not installed" prompt after this step run the following command before continuing with later steps - $ sudo yum install zlib-devel
     
    $ make
    $ make install
     
    And there you go, now libpng 1.6 should be up and running on your system
