The tests in BCP_lp_user::test_full() (similar tests in test_binary() and test_integer())
if (val < vari->lb() - etol || val > vari->ub() + etol)
return(NULL);
might make test_full() return "infeasible" for a solution where all integer variables are indeed integer (with precision etol), but a continuous variable is slightly below its lower bound. Then BCP will fail, as no branching variable can be found.
I would use this test only for integer variables.

Removing -mno-cygwin gives a successful build, but isn't really a fix.

Hi,
when using Bcp as part of CoinAll on Solaris, the configure is failing in the section related to the copying of the examples

The message I get in configure is:
...
checking whether this is a VPATH configuration... yes
Creating links in test/BAC ...
cat: cannot open ..../../../../code/Bcp/examples/BAC/testfiles.txt

I have a directory ./code where I checked out CoinAll, and do a VPATH-configure from ./debug .
It looks like something with the path is not working correct there.
Unfortunately, I do not have the right autotools on this machine, so I did modification on Bcp/configure to get it working.
The first thing was as follows:

Hi,
I am using Mac OS X 10.6.8 (10K549) with gcc4.3 +gfortran (Not directly related to this problem but I could not compile the code with gcc45 and gcc46). As instructed in the configure.site file, I have declared the cplex include and library directories as follows:

with_cplex_lib='-L/CPLEX/cplex/lib/x86-64_darwin9_gcc4.0/static_pic -lcplex -lpthread'
It says it can't compile the simple test code that calls CPXgetstat. I don't think the problem is a cplex licence problem because the ILM file path is a global env var on my system.
I couldn't attached the configure log, so here is a snapshot:

Keywords: make build compile mac OSX
I get a compile error when compiling the file Bcp/src/include/BCP_os.hpp
under mac OS X 10.4 / Darwin:
/usr/include/sys/resource.h:218: error: declaration does not declare anything
make: *** [BCP_cg_main.lo] Error 1
See file: Bcp/src/include/BCP_os.hpp
:
#if HAVE_SYS_RESOURCE_H
# include <sys/resources.h>
#else
# define setpriority(x,y,z)
#endif
Firstly, when I build, HAVE_SYS_RESOURCE_H is incorrectly undefined. I think this is due to a bug in autoconf. I get around this by manually export
ing the CXXDEFS
environment variable to "-DHAVE_SYS_RESOURCE_H
" prior to running configure.
Secondly, I think # include <sys/resources.h>
should be changed to # include <sys/resource.h>
in the code quoted above (at least, this is the case for Darwin / Mac OS X 10.4).
Making this change gets rid of the compile error. However, note that the code also doesn't compile for me even when HAVE_SYS_RESOURCE_H
is not defined. This is because, on my system, resource.h
gets #include
d via a different dependency, and its definition of setpriority
is messed up by the code above. So I think a better plan is to remove the whole block of code quoted above from Bcp/src/include/BCP_os.hpp
, and change line 33 of Bcp/src/include/BCP_os.hpp
to
#ifdef HAVE_SYS_RESOURCE_H
setpriority(PRIO_PROCESS, 0, p.par.entry(BCP_cg_par::NiceLevel));
#endif
This successfully compiles on my system.

Hello,
I am trying to build Bcp on Windows (MSVC++), but now using the svn code just the way I downloaded it. I had a problem in the file BCPconfig.h, line 53.
/* a few things that exists under unix, but not under windows */
#include <Windows.h>
#define gethostname(c, l) { DWORD cnlen = l; GetComputerName(c, &cnlen); }
#include <process.h>
My suggestion would be enclose those lines in a #ifndef, so that there is no need to change the code when working on Windows.
An addition, when I checked out the BCP project I got the file OsiCpxSolverInterface.hpp in folder E:\MVSProjects\COIN_svn\Bcp\Osi\src\OsiClp (OSi CLP folder), but I think this file was not suppose be there.
Thanks and congratulations for the nice work,

This is important when BCP works with Cplex and uses cut generators requiring access to the optimal basis.
This is not necessary when using Clp.
The difference is in the implementation of OsiCpx and OsiClp.
In OsiCpx, any change of bounds on the variables makes all
information about the optimal basis disappear. For OsiClp,
it remains there and can be used if primal feasibility
is not lost.

This is for the tar ball BCP-1.0.0, but the code in the stable version looks similar.
It seems that the counting of processed nodes when BCP hits the time limit is incorrect. I get:
TM: Time has ran out.
TM: Best lower bound in this phase: 17.000000
WARNING! processed != p->search_tree.processed()
WARNING! Please file a bug report.
When printing these values, I get:
processed: 2195 p->search_tree.processed(): 1329
This happens using stein27.mps with an upper bound of 18.1, a time limit of 10 seconds and BCP in Branch-and-Bound (using best bound) mode.
This comes from BCP_tm_user::display_final_information(). Moreover, when using
BCP_RemoveExploredBranches 1
it happens that in the loop of BCP_tm_user::display_final_information()
starting with
for (BCP_vec<BCP_tm_node*>::iterator node = p->search_tree.begin();
node != p->search_tree.end();
++node) {
(around line 291 in BCP_tm_user.cpp), *node is sometimes NULL, creating a crash. I fixed this by adding at the beginning of the loop:
if(*node == NULL) {
continue;
}
I am not sure if this is the best fix.

Dear Sir/Madam,
I tried to install Bcp by following the instructions from the INSTALL file. After downloading I did the following within my Bcp directory:
mkdir build
cd build
../configure
During configuration I got these messages:
checking sys/resource.h usability... no
checking sys/resource.h presence... yes
configure: WARNING: sys/resource.h: present but cannot be compiled
configure: WARNING: sys/resource.h: check for missing prerequisite headers?
configure: WARNING: sys/resource.h: see the Autoconf documentation
configure: WARNING: sys/resource.h: section "Present But Cannot Be Compiled"
configure: WARNING: sys/resource.h: proceeding with the preprocessor's result
configure: WARNING: sys/resource.h: in the future, the compiler will take precedence

configure: WARNING: ## --------------------------------------------------------- ##
checking for sys/sysinfo.h... yes
So I do the report ...
I've got these errors with version 1.2.2, and 1.2.3 as well on a SUSE 11.2 system. The make command was successful, but not make test (segmentation fault). Maybe, that this is related to the messages during configuration? I don't have no idea.
I checked the Autoconf documentation, but I don't have no idea what to do in this special case.
I would be grateful for any assistance you can offer.
Thank you very much in advance!
