How to install wget in macOS? [closed]

I try to install wget in MAC OS 10.11.1 but when I run ./configure --with-ssl=openssl I get this error:

configure: error: --with-ssl=openssl was given, but SSL is not available.

How to resolve this problem in OSX 10.11.1?

Using brew

First install brew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And then install wget with brew and also enable openressl for TLS support

brew install wget

Using MacPorts

First, download and run MacPorts installer (.pkg)

And then install wget:

sudo port install wget

For macOS Sierra, to build wget 1.18 from source with Xcode 8.2.

Install Xcode
Build OpenSSL

Since Xcode doesn't come with OpenSSL lib, you need build by yourself. I found this: https://github.com/sqlcipher/openssl-xcode, follow instruction and build OpenSSL lib. Then, prepare your OpenSSL directory with "include" and "lib/libcrypto.a", "lib/libssl.a" in it.

Let's say it is: "/Users/xxx/openssl-xcode/openssl", so there should be "/Users/xxx/openssl-xcode/openssl/include" for OpenSSL include and "/Users/xxx/openssl-xcode/openssl/lib" for "libcrypto.a" and "libssl.a".
Build wget

Go to wget directory, configure:
```
./configure --with-ssl=openssl --with-libssl-prefix=/Users/xxx/openssl-xcode/openssl
```
wget should configure and found OpenSSL, then make:
```
make
```
wget made out. Install wget:
```
make install
```
Or just copy wget to where you want.
Configure cert

You may find wget cannot verify any https connection, because there is no CA certs for the OpenSSL you built. You need to run:

New way:

If you machine doesn't have "/usr/local/ssl/" dir, first make it.
```
ln -s /etc/ssl/cert.pem /usr/local/ssl/cert.pem
```
Old way:
```
security find-certificate -a -p /Library/Keychains/System.keychain > cert.pem
security find-certificate -a -p /System/Library/Keychains/SystemRootCertificates.keychain >> cert.pem
```
Then put cert.pem to: "/usr/local/ssl/cert.pem"

DONE: It should be all right now.

You need to do

./configure --with-ssl=openssl --with-libssl-prefix=/usr/local/ssl

Instead of this

./configure --with-ssl=openssl

I update mac to Sierra , 10.12.3

My wget stop working.

When I tried to install by typing

brew install wget --with-libressl

I got the following warning

Warning: wget-1.19.1 already installed, it's just not linked.

Then tried to unsintall by typing

brew uninstall wget --with-libressl

Then I reinstalled by typing

brew install wget --with-libressl

Finally I got it worked.Thank God!

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And then install wget with brew and also enable openressl for TLS support

brew install wget --with-libressl

It worked perfectly for me.
