[Cbc] CBC Binaries for the Windows 64-bit VC14 Platform

[James Howey]

I can't answer your question directly, but I can suggest that the quickest
way to get online is to go ahead and download the source and build it. 

 

The source comes with vs10 projects. When you first open the solution, allow
vs to upgrade the projects to your version. I don't believe the available
binaries are built for any other vs version.

 

It almost builds out of the box. 

*         There are a couple missing libs in the project include file lists.

*         There are a bunch of expected .h files which are to be found in
the windows sdk. Download it and update references to point properly.

 

You should be ready to go in an hour or two.

Dear all,

 

I am trying to link the CBC binaries with my Windows 64-bit application
which is built using Visual C++ VC14. I am unable to find such libraries
from the CBC repositories:

According to the CBC homepage (https://projects.coin-or.org/Cbc/wiki
<https://urldefense.proofpoint.com/v2/url?u=https-3A__projects.coin-2Dor.org
_Cbc_wiki&d=DwMFAg&c=Ngd-ta5yRYsqeUsEDgxhcqsYYY1Xs5ogLxWPA_2Wlc4&r=TNTf22dcc

6MZE&s=k3YIUR6LyciHCi8XSkmlXVI_gg-1-bnLDo04OfFv2HM&e=> ), we can request for
the latest version for the missing platform (Cbc-2.9.9-win64-msvc14) to be
built and posted. If that is true, can it be done please? Thanks!

 

I attempted to link my Win64 application with the 32-bit binaries
(Cbc-2.9.9-win32-msvc14.zip) that are available, but my build failed due to
mismatched symbols everywhere. For example, for the OsiClpSolverInterface
constructor, the linker is looking for:

my_main_test.obj : error LNK2019: unresolved external symbol "public:
__cdecl OsiClpSolverInterface::OsiClpSolverInterface(void)"
(??0OsiClpSolverInterface@@QEAA at XZ) referenced in function "int __cdecl
my_main_test(void)" (?my_main_test@@YAHXZ)

but the supplied win32 libOsiClp.lib contains:

??0OsiClpSolverInterface@@QAE at XZ (public: __thiscall
OsiClpSolverInterface::OsiClpSolverInterface(void))

 

Are the mismatched symbols due to 32/64-bit incompatibility, or due to
special compiler flags utilized by CBC (and, if so, where can I find these
CBC compiler flags for the Visual C++ platform)?

 

Your help will be greatly appreciated!

 

Best regards,

 

Thomas
