Difficulties to install Oscar

[maxime...@univ-lille1.fr]

Hello,
 
I tried to install OscaR to use it in a sbt project.
I was unsuccessful. I have done the following steps.

0a. Install glpk lp_solve i.e.
brew tap homebrew/science
brew install lp_solve
brew install glpk
0b. Install gurobi7.0.2_mac64.pkg
1. Download oscarlib-oscar-2daaec79ae02
2. cd oscarlib-oscar-2daaec79ae02
3. sbt -Djava.library.path=lib/macos64/:/usr/local/lib/
4. project oscar-algebra
5. package
6. project oscar-linprog
7. package
8. copy oscar-algebra_2.11-3.1.0.jar and oscar-linprog_2.11-3.1.0.jar in MYPROJECT/lib/
9. Create a simple example

import oscar.linprog.modeling._
import oscar.linprog._
import oscar.algebra._
object TestLinProg {
  def main(args: Array[String]) {
    val lp = LPSolver()
    val mip =MIPSolver()
    val x0 = LPVar(lp,"x0",0,40) // can take value in continuous interval [0,40]
    val x1 = LPVar(lp,"x1",0, 1000)
    val x2 = LPVar(lp,"x2",0 ,17)
    val x3 = LPVar(lp,"x3",2,3)

    lp.maximize(x0+2*x1+3*x2+x3) subjectTo {
      lp.add(-1*x0 + x1 + x2 + 10*x3 <= 20)
      lp.add(x0 - 3.0*x1 + x2 <= 30)
      lp.add(x1 - 3.5*x3 == 0 )
    }
    println("objective"+lp.getObjectiveValue())
    println(x1.getValue())
  }


10. sbt -Djava.library.path=/usr/local/lib/
11. compile

I have the following error :
Compiling 1 Scala source to .../scala-2.11/classes...
[error] .../TestLinProg.scala:12: not found: value LPSolver
[error]     val lp = LPSolver()


Any idea ?


Thanks in advance for your help,


MM.

Dear Maxime,

Which version do you depend on in your SBT?

We will remove the linprog package from OscaR pretty soon.

As you seem to have a university affiliation, we advise you to use gurobi/cplex java api instread.

Best regards,

Pierre
