Attempting to install the zlib-devel on mac os x mavericks with homebrew doesn't work:
These include GCC, GNU make, xz, perl, libgmp, libffi, and zlib. We also recommend Git and GPG. To install these using your package manager. Manual download. (Windows) or System Preferences (Mac) would not result in stack traffic going through the proxy. Download Composer Latest: v1.8.6. To quickly install Composer in the current directory, run the following script in your terminal. To automate the installation, use the guide on installing Composer programmatically.

Please fix this so we don't need to manually hack CFLAGS to amke it work. This comment has been minimized. On Mac Mojave, add CFLAGS to to the environment. I would have liked to add `I$(xcrun -show.
This install
works fine though.
And finally, verify all the set up details and click the magic button to update. Mac how to setup manual wifi ip.

Just run in the command line:
In OS X 10.9+, the command line developer tools are now installed on demand. So after running this also zlib and zlib-devel should be available (no need for brew install zlib..)
For OS X Mojave
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
The reason is because Xcode Command Line tools no longer installs needed headers in /include. You have to run a separate command to install the needed headers.
As noted here - https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes
The command line tools will search the SDK for system headers by default. However, some software may fail to build correctly against the SDK and require macOS headers to be installed in the base system under /usr/include. If you are the maintainer of such software, we encourage you to update your project to work with the SDK or file a bug report for issues that are preventing you from doing so. As a workaround, an extra package is provided which will install the headers to the base system. In a future release, this package will no longer be provided. You can find this package at: /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg To make sure that you're using the intended version of the command line tools, run xcode-select -s or xcode select -s /Library/Developer/CommandLineTools after installing.
SundarZlib Mac Manual Installer
Sundarxcode-select --install doesn't solve this on Mojave for some reason.
Since this is the only library blocking, go to https://www.zlib.net and download source code. Select the 'US (zlib.net)' hyperlink about halfway down the page for the tar.xz version.
Then find the download on your local machine and double click on the file. This will unzip the download and create a new folder in the same directly.
Then in Terminal:
cdinto the directory with the download- then
tar -xvf zlib-1.2.11.tar.xz(Note thatzlib-1.2.11.tar.xzmay change depending on the latest version you've downloaded. Just run whatever file you're just downloaded.) - Change directories
cd zlib-1.2.11 ./configuremakemake install
After running
Make sure your export these variables for the compiler and the pkg-config to find zlib
For compilers to find zlib you may need to set:
For pkg-config to find zlib you may need to set:

Unfortunately none of the above methods worked for me So I did

I'm completely new to Ubuntu. I got installed it because my school uses a lot of Linux type stuff in my school's Computer Science program so I figured I would use Ubuntu on my own machine and just do my code from there instead of the computer labs. However, I'm having a lot of trouble trying to install the numerous packages that aren't included natively on Ubuntu. Can someone help me install the PNG library, libpng and zlib. This is just one of many things I need to get on here but I think I need to first start off with this. I did download both packages, did the tar xf thingy on the download, and looked at the README files for insight on installing the software. I get weird errors though. I first tried installing libpng and the terminal was like zlib isn't installed so I was like ok, I'll just get zlib but permission is denied. Do I need to get root or something? I remember seeing people say root before, but I don't know if it is relevant. I'm really new so I don't understand a lot of these things and it's kinda scary. Please help.

Zlib For Ubuntu

For zlib, run:
hwezhwezUbuntu uses a thing called apt, which is a package manager. It installs, manages, upgrades, and removes programs. If at all possible, you should try to install programs via Ubuntu Software Center. What you were likely attempting to do was install from source, which is only recommended if you know what you're doing.
Try to get out of the Windows mentality, which is to search google and download an installer. The Ubuntu Software Center searches Ubuntu's online repositories, which are generally guaranteed to work. Programs installed via Software Center or apt will also be updated automatically by Ubuntu's Software Updater.
You can install libpng from the Software Center by searching libpng and choosing 'PNG Library - runtime'. Or from here libpng12-0 by clicking 'available on the Software Center'. Or using sudo apt-get install libpng12-0 from a terminal.
The zlib1g package should be installed automatically when you install libpng12-0, because it is one of the libpng12-0 package's dependencies. The package manager apt installs all of a package's dependencies before it installs the package.
