Thank you very much.

Please download glpk-4.46.tar.gz and glpk-4.46.md5 from .

To test the package please do the following:

1. Build the package. On running the configure script under Linux you do
not need to specify --with-zlib, because now zlib is incorporated into
the distribution.

2. Take some (large enough, say, 100-200Kb) lp/mip file, say, foo.mps,
pack it to foo.mps.gz with gzip or equivalent utility, and pass it to

   glpsol --check foo.mps.gz

Make sure that the file has been successfully read.

2. Run glpsol as follows:

   glpsol --check bar.mps --wmps bar.mps.gz

and make sure that bar.mps.gz can be correctly unpacked with gzip.

Please test the package under both 64-bit Linux and Windows. If there
will be some compiler warnings, please inform me.

Best regards,

Andrew Makhorin
