[Coin-discuss] VolLp Example

[Daniele Ficcadenti]

Hi everybody,
I have problems on compiling VolLp Example.

I downloaded the tarballs (08/26/2002 version) and
decompressed the following modules:
Vol, Osi, VolLp and VolUfl.

My target is to try and understand the two Examples
VA related: VolLp and VolUfl.

I proceeded as follow:

1. I compiled Vol module successfully.
2. I compiled and tested (with unitTest and
    unitTest -testOsiSolverInterface)
    the Osi module successfully.
3. I compiled and tested VolUfl example successfully.
4. I tried to compile VolLp example, but I obtained
    an "Error 1". Naturally, The executable (vollp)
    was not generated.

    The messages that i obtained from the "make"  command are:
