SCIP not available in jnilinearsolver.jar #9

Closed GoogleCodeExporter closed 9 years ago

I downloaded Google.OrTools.java.x64.1304.zip and tested my installation with 
IntegerProgramming.java using the compiled jars.

When I run the program GLPK and CBC worked fine, but not SCIP. I got the 
following output:

---- Integer programming example with GLPK ----
Problem solved in 70 milliseconds
Optimal objective value = 6.0
x1 = 6.0
x2 = 0.0
Advanced usage:
Problem solved in 3 branch-and-bound nodes
---- Integer programming example with CBC ----
Problem solved in 346 milliseconds
Optimal objective value = 6.0
x1 = 6.0
x2 = 0.0
Advanced usage:
Problem solved in 0 branch-and-bound nodes
---- Integer programming example with SCIP ----
Could not create solver SCIP_MIXED_INTEGER_PROGRAMMING

I was expecting to have access to the SCIP wrapper, but apparently it is not 
available in jnilinearsolver.jar. How can I have access to SCIP from your 
wrappers?

By the way, I run my program on Eclipse Indigo with Java JRE 7 on Windows 7 
Enterprise 64 bit.

Last, but not least, thanks for putting this together. It is amazing!

Hello, 

I have not found a good way to integrate scip inside the windows linear part.
I cannot compile scip on windows using only visual studio.
You can download the libraries, but they are dynamic, which will creates 
problems.
And these libraries do not include the header files. 

So, it is complex.
I will try to make some time to make it work.
