Re: [Help-glpk] [Fwd: Question on installation of glpk]

[Heinrich Schuchardt]

Dear Wei,

your mail had to be forwarded manually because you are not subscribed to
the GLPK help list, see,
https://lists.gnu.org/mailman/listinfo/help-glpk

The current version of GLPK is 4.60.

The result that you see for the signature is what is expected because
Andrews key was not signed by anybody you trust.

In fact Andrew's key has not be signed by anybody. (And it should only
be signed by somebody meeting him in person.)

Furthermore a key length of 1024 bit was ok in 2003 when Andrew created
the key but has to be considered too short today.

To install GLPK you have to run:

wget http://ftp.gnu.org/gnu/glpk/glpk-4.60.tar.gz
tar -xzf glpk-4.60.tar.gz
cd glpk-4.60
./configure
make
make check
sudo make install
sudo ldconfig

Please, observe that the library is installed in /usr/local/lib by
default. This directory is not in the library search path of some Linux
distributions like Fedora. One way to overcome this is setting
LD_LIBRARY_PATH.

Best regards

Heinrich Schuchardt
