Build information was modified from original at Fragrant Memories.
wget and curl are utilities for downloading files and webpages via the command line.
You can install a pre-built wget 1.12 from msys:
mingw-get install msys-wget
The instructions below will install a newer version of wget with some bugfixes.
libssh2 (It is optional, remove --with-libssl2=/usr/local option to do without it).
You can use 7-zip for extracting files instead of tar.
Download the latest release of wget from the GNU FTP site, currently wget-1.18.tar.gz.
Move the download to your home directory.
Extract using tar:
cd
tar xvfz wget-1.18.tar.gz
Change to the build directory:
cd wget-1.18/
Configure the makefile to use pthreads, OpenSSL, and disable native language support (NLS). This takes a few minutes:
./configure --enable-threads=win32 --disable-nls --with-ssl=openssl CC=-std=c99
The default --prefix option was /usr/local, change this if desired to install elsewhere.
The last version of MinGW changed some headers causing problems. TODO: fix this error:
spawn-pipe.c: In function 'create_pipe':
spawn-pipe.c:193:41: error: 'environ' undeclared (first use in this function)
(const char **) environ);
Run make, then install wget:
make
make install
OpenSSL based programs can check a certificate bundle file when making secure connections.
If you built openssl yourself:
cd /usr/local/ssl/certs/
If you used the msys-openssl package:
cd /var/ssl/certs/
Download the file from the curl website using wget:
wget --no-check-certificate http://curl.haxx.se/ca/cacert.pem
If you don't have wget, you can copy cacert.pem from your browser: http://curl.haxx.se/ca/cacert.pem
Verify the fingerprint:
openssl x509 -noout -fingerprint -in /var/ssl/certs/cacert.pem
Add this line to your .profile:
export SSL_CERT_FILE=/usr/local/ssl/certs/cacert.pem
You could use wget to download curl source, or do it the "old-fashioned way" from web browser at curl.haxx.se.
cd
wget https://curl.haxx.se/download/curl-7.51.0.tar.gz
tar xvfz curl-7.51.0.tar.gz
I needed to set an environment variable for SSL support to be included, it shouldn't have been needed:
export LIBS=-lz
Change to the directory, configure for MinGW, make, and install:
cd curl-7.51.0
./configure --build=i686-pc-mingw32 --with-zlib --with-libssh2 --with-ssl=/usr/local
make
make install
You can run configure --help to see all configuration options. For example, --disable-shared will build curl with static libraries. This increases the file size, but removes dependencies on DLLs.
TODO: more options, like IPv6, Kerberos, international domain names
/usr/local/lib/
libcurl.la
libcurl.a
pkgconfig/*.pc
/usr/local/include
curl/
/usr/local/bin/
curl.exe
curl-config
Here's an example to download a file from a redirected URL:
curl -LOJ https://api.github.com/repos/SFML/SFML/tarball/master
-L, --location
If the server returns a 3XX redirect code, redo the request at the new location
-O, --remote-name
Write output to a local file
-J, --remote-header-name
Use the server-specified filename instead of extracting a filename from the URL.
