[Coin-discuss] Compiling error

[Markus Behle]

Hi,

I've seen your COIN session at the ISMP and wanted to start
using your software. So I downloaded it today
and started compiling the Osi Interface
on a Linux Debian with gcc 2.95.4 (and with 3.0, 3.2.1).
But there were always compiling errors:

Compiling OsiVolSolverInterface.cpp
OsiVolSolverInterface.cpp: In member function `virtual CoinWarmStart*
    OsiVolSolverInterface::getWarmStart() const':
OsiVolSolverInterface.cpp:724: cannot allocate an object of type `
    CoinWarmStartDual'
OsiVolSolverInterface.cpp:724:   because the following virtual functions are
    abstract:
${HOME}/COIN/include/CoinWarmStart.hpp:21:   virtual
    CoinWarmStart* CoinWarmStart::clone()

This sounds like a real error. I also tried it with
different GNU Compilers on a Sun Solaris machine
but the error is of course always the same.
Hmm, it sounded so easy to use COIN...
Can you please tell me what I'm doing wrong?

Regards
