Re: [Help-glpk] [Fwd: 64 bit]

Hello Francesco

To answer your question about a flag to switch between
32-bit or 64-bit builds.

In general there is not.  Your compiler must know what
kind of system it is on.  If you wish to cross-compile
to another platform, then you will need to specify that
explicitly.  For GCC:

  -b machine : The argument machine specifies the
               target machine for compilation.

GLPK does have several configuration options.  For
example, I use (64-bit Linux) the following because
I don't wish to burden users with run-time dependencies:

  $ ./configure --disable-shared

As Xypron said, pre-build Windows binaries are
available.  The GLPK wikibook also has entries for building
GLPK on Windows, Mac OS X, Linux, and Solaris:
