[Coin-discuss] Running Bcp on Windows

[Jörg Herbers]

Hi Jesper,

BCP compiles on cygwin and with some modifications on Visual C++ .NET 2003. 
Most of the necessary changes are due to persistent problems of VC7 with 
templates:

BCP_lp_branching.cpp:275: const int maxind = std::max<int>(rownum, colnum);
BCP_lp_colrow.cpp:401: 
std::min<size_t>(p.param(BCP_lp_par::MaxCutsAddedPerIteration),
BCP_lp_colrow.cpp:495: 
std::min<size_t>(p.param(BCP_lp_par::MaxVarsAddedPerIteration),
BCP_lp_create_lp.cpp:125: const int num = std::max<int>(varnum, cutnum);
BCP_lp_fathom.cpp:260: std::max<const size_t>(
BCP_lp_generate_cuts.cpp:166: tout = std::max<double>(0.0, tout - 
(BCP_time_since_epoch() - tin));
BCP_lp_generate_vars.cpp:162: tout = std::max<double>(0.0, tout - 
(CoinCpuTime() - tin));
BCP_lp_main.cpp:32: p.node->vars.reserve(std::max<int>(1000, 3 * bvarnum));
BCP_lp_main.cpp:42: p.node->cuts.reserve(std::max<int>(1000, 3 * bcutnum));
BCP_lp_pool.cpp:8: _violation = std::max<double>( 0.0, 
std::max<double>(_row->LowerBound()-lhs,
BCP_message_single.cpp:251: _lp_prob->upper_bound = 
std::min<double>(_tm_prob->ub(), DBL_MAX/2);

BCP_timeout.cpp needs the following extensions:

#if defined(_MSC_VER) && (_MSC_VER > 1300)
#  include <time.h>
#endif

double BCP_time_since_epoch() {
   BCP_DEFAULT_NAMESPACE;
#if defined(_MSC_VER)
   unsigned int ticksnow;
   ticksnow = (unsigned int)clock();
   return (double)((double)ticksnow/CLOCKS_PER_SEC);
#else
  /* ... as before ... */
#endif
}

Furthermore, I use an OS specific header file (BCP_msvc.hpp):

#ifndef _BCP_MSVC
#define _BCP_MSVC

typedef int BCP_IndexType;

#  define setpriority(x,y,z)
#  define BCP_USE_RUSAGE 0
#  include <Windows.h>
#  define gethostname(c, l) { DWORD cnlen = l; GetComputerName(c, &cnlen); }
#  include <process.h>
#  define BCP_PtrDiff       int
#  define BCP_DEFAULT_NAMESPACE

#    define NEED_TEMPLATE_CLASSES
// #    define NEED_TEMPLATE_FUNCTIONS
// #    define NEED_STD_TEMPLATE_FUNCTIONS
// #    define NEED_IMPLICIT_TEMPLATE_CLASSES
// #    define NEED_IMPLICIT_TEMPLATE_FUNCTIONS
#    define BCP_CONSTRUCT     std::_Construct
#    define BCP_DESTROY       std::_Destroy
//#    define BCP_DESTROY_RANGE std::_Destroy_range

template<class T> inline void BCP_DESTROY_RANGE(T *first, T *last)
{
  for (; first != last; ++first)
    BCP_DESTROY(first);
}

#endif

which is included in BCP_os.hpp:

#if defined(_MSC_VER) && (_MSC_VER > 1300)
#  include "BCP_msvc.hpp"
#endif

>From my viewpoint, it would be helpful to integrate these changes in BCP. 
But since the changes are due to compiler flaws, this again leads us to the 
discussion on how many and which compilers BCP should support...

Hi Jesper,
I believe BCP will compile using CYGWIN on Windows.

Hi Jesper,

Yes, I tried it, and it's a no go. BCP uses templated member functions and
VC++-6.0 can't handle them. It claims that there's a syntax error. I boiled
the problem down to a trivial example, contacted Microsoft and they
admitted
the error in the compiler.

On the bright side, VC++-7 is supposed to be much more standards compliant,
so
you may get Bcp working with it.

Good luck,
--Laci
