Thanks, Ted!<br>
<br>
I added my CPLEX library, added a libOsiCpx project, and changed the
preprocessor definitions from<br>
<br>
__DECOMP_LP_CLP__<br>
__DECOMP_IP_CBC__<br>
<br>
To<br>
<br>
__DECOMP_LP_CPX__<br>
__DECOMP_IP_CPX__<br>
<br>
This results in the algorithm terminating with a range constraint error
(probably an issue with my model). I then changed it to<br>
<br>
__DECOMP_LP_CLP__<br>
__DECOMP_IP_CPX__<br>
<br>
With the option SolveRelaxAsIp = 1 and it runs to optimality. However, it
seems like it is still using CBC for solving subproblems. I noticed that
the MSV text editor shows blocks with<br>
<br>
#ifdef __DECOMP_IP_CPX__<br>
...<br>
#endif<br>
<br>
And<br>
<br>
#ifdef __DECOMP_LP_CPX__<br>
...<br>
#endif<br>
<br>
<br>
As "Inactive Preprocessor Block" (e.g. in decomp.h). I guess
that these blocks are not read for some reason. Anyone have an idea what
might be the issue here?<br>
<br>
I also tried to replace<br>
<br>
#define __DECOMP_LP_CLP__<br>
#define __DECOMP_IP_CBC__<br>
<br>
with<br>
<br>
#define __DECOMP_LP_CPX__<br>
#define __DECOMP_IP_CPX__<br>
<br>
In DecompConfig.h without luck.<br>
<br>
Thanks again,<br>
Jonas<br>
<br>
PS. I am using MSVC++2008<br>

The config.site is for builds using the autotools in *nix<br>
environments. To use CPLEX in DIP with MSVC++, you would have to<br>
manually add<br>
<br>
-D__DECOMP_IP_CPX__ -D__DECOMP_LP_CPX__<br>
<br>
to the compiler defines and also add the CPLEX library as a<br>
dependency. If you're not familiar with how to do either one of these<br>
steps, post more information about which version of MSVC++ you're<br>
using and I can be more specific.<br>
<br>
Cheers,<br>
<br>
