[FW] Installing GLPK on a Mac

So you want copy-paste instructions to install GLPK on your Macbook? Here are the steps:

1. Download the latest version of GLPK fromhttp://www.gnu.org/software/glpk/#downloading
   
2. Optional: Follow the instructions to verify the download (you might need to get GNU Privacy Guard or gpg for this. You can get it at http://gnupg.org);
   
   The GLPK distribution tarball can be found on http://ftp.gnu.org/gnu/glpk/ [via http] and ftp://ftp.gnu.org/gnu/glpk/ [via FTP]. It can also be found on one of our FTP mirrors; please use a mirror if possible.
   To make sure that the GLPK distribution tarball you have downloaded is intact you need to download the corresponding .sig file and run a command like this:
   gpg --verify glpk-4.32.tar.gz.sig

   
   If that command fails because you do not have the required public key, run the following command to import it:
   gpg --keyserver keys.gnupg.net --recv-keys 5981E818

   
   and then re-run the previous command.
   (if gpg is not installed, refer to: http://hichenwang.blogspot.com/2011/08/install-pgp-on-mac-os-x.html)
3. Say it’s downloaded to your “Downloads” directory, go there and execute the following commands (using the terminal)
   view sourceprint?

   1.cd ~/Downloads

   2.tar -xzf glpk-4.43.tar.gz

   3../configure --prefix=/usr/local # see note [1]

   4.make

   5.sudo make install
4. At this point, you should have GLPK installed. Verify it:
   view sourceprint?

   1.which glpsol

   2./usr/local/bin/glpsol
5. … and try help:
   view sourceprint?

   1.glpsol --help

Now that you are all set-up, read up this excellent introduction using GLPK:http://www.ibm.com/developerworks/linux/library/l-glpk1
