Andrew/Xypron,
In GLPK-4.27, config.h.in contains HAVE_SQL_H, but it does not contain:
HAVE_SQLEXT_H
HAVE_WINDOWS_H
as it was in Xypron's glpk-4.26-tab version for compiling under
Windows.
Am I correct in assuming that, on my Windows platform, I'm currently
limited to xBase and CSV unless I bui
True. However, it requires the user to (know how to) make the ODBC
connection, rather than directly addressing an xBase or sqlite file
from within the MathProg routine. That was my definition of
portability.
While it would be one extra step for me (or you), I'm thinking about
the time when I m
...and here are my notes if you want to do the same using MinGW.
Thanks, Xypron. What I realized, at the end of all of this, is that
ODBC immediately takes away portability because of the requirement to
link the MySQL database using ODBC. So far, for portability, we have
CSV and xBase. Yours an
Xypron/all,
In trying to build the version (glpk-4.26-tab_r100), I must be missing
something. I used the w32 Build_GLPK_with_Dev.bat file, after properly
pointing the HOME variable to Dev-Cpp.
GLPSOL built without error. I used the transp.sql file to create the
necessary data in mysql. Then,
Andrew,
I followed these instructions and successfully compiled and tested
glpsol under WinXP using dev-cpp. Thank you and xypron, too, for
extending MathProg and adding this new feature. I look forward to
using it.

Andrew,
Back in November, you and Xypron had a brief discussion on his mods to
introduce MySQL connectivity into MathProg. Simple declarative
statements, as you'd proposed, would improve its functionality for me.
Can you tell me if that is an issue that is moving forward? If it's
not, what wo
Thanks, Andrew. I started with help-glpk as I'm working in MathProg,
however, I will try sci.op-research, too.

All,
I've been wracking my head over a network flow model issue, googled all
around, and still can't determine if I can model something
successfully.
I have a simple three-node network to be evaluated over 365 days: one
source, one sink, and one node which serves as a reservoir. The source

Thanks. I wasn't thinking of the obvious today.

I'll look at gcc -E. glpsol -d would only work if I could name
multiple data files, since they are getting to be quite large and
unidimensional!
Thanks,

Although the MathProg manual doesn't list it, is there an 'include'
statement that can be used in an input file? Currently, I'm developing
a number of scenarios of daily data over an entire year. It would be
nice to be able to 'include' data by reference, instead of copying it
into each file. Co
Hi everyone,
I am trying to formulate a transportation problem (with intermediate storage

day-to-day over a 365-day period. Google doesn't provide any help, looking for
