    The documentation for using IBM ILOG CPLEX with Microsoft Visual C++Visual explains how to define a project in "win32 release" mode should be created.
    I'm trying to compile and link my model as "win32 debug" mode to enable debuging the code.
    I'm using Visual C++ 2008 express .

    It seems that there is a conflict between some compliled functions in the debug version libcmt.lib and the realase one that is used by the libraries provided with cplex.

    I get the following error messages

    1>------ Build started: Project: TS_BSRP, Configuration: Debug Win32
    1>Linking...

    It is is possible to force the linker to ignore one of the copies of these function using the command
    line switch "/FORCE:MULTIPLE". This enable compiling the program but with numerous warnnings as follow

    The program seems to work fine for now but I don't feel like go on programming with these warning that I don't fully understand.

    Is there any solution for this issue?
    Alternativly, is it safe to ignore these warinings?
    I vaguely remember that in previois versions Ilog provided a debug version for each library, is there any way tp obtain one from IBM?
