How to install wget in macOS? [closed]

Question

Using brew

First install brew:

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

And then install wget with brew:

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.

1. Install Xcode

2. 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".

3. 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.

4. 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
