Re: [Help-glpk] glpk 4.27 release information

[glpk xypron]

Hello Ted,

compiling under windows requires
#include <window.h>

In Andrews release 4.27 this statement is deactivated in glpsql.c

To create a release, that can be compiled under Linux as well as MinGW and 
Cygwin without editing any files, please, replace
configure.ac
configure
config.h.in
src/glpsql.c
with the files from 
ftp://glpk.dyndns.org/glpk/glpk-4.27-patch-for-odbc.zip

The configure script automatically detects if the target system is Windows 
(Cygwin, MinGW). Only in this case the presence of windows.h is checked and  
HAVE_WINDOWS_H defined. Instead of linking to the iODBC library,  odbc32.dll is 
linked. You can then setup the data source in the Windows "Control Panel".

>From the start menu choose
Settings -> Control Panel -> Administrative Tools -> Data Sources (ODBC)

The appended MS Access 95 database glpk.mdb contains the sample data for 
sudoku_odbc.mod and tranps_odbc.mod. Supposed Access is installed You can setup 
a datasource with name "glpk" for glpk.mdb.

Best regards

Xypron
