Linker error

Jump to solution

I am converting a QW program from CVF to IVF with VS2013.  When I try to build, I receive several error messages I do not understand. Please see blow. Can someone give me a tip?

Some of your objects depend on LIBCMT.lib and some others on LIBCMTD.lib; linking these causes multiple definitions to occur.

My suspicion is that the library C:\DVFORTRAN\PCLIBDF\Release\PCLIBDF_.lib was compiled without /dbglibs. If so, and you have the sources for that library, recompile the library with /dbglibs. If not, do not specify /dbglibs when compiling your sources in C:\CALC\CaFeMS.

Thank you for your comments, meceg4.

The /dbglibs is for debugging purposes, right? It  was my believe you could build using  obj files compiled with or without the above /dbglibs, but then, in case of stepping into a routine in the PCLIBDF_lib would get a  message telling that the code is not available.. Buts that is not correct...

/dbglibs simply means that you want to link against the debug version of the MSVC libraries. (There are debug versions of the ifort libraries but they are there just so that the MSVC debug libraries can be used.) The MSVC debug libraries enable you to step into the MSVC library code (if you have installed the CRT sources) and, perhaps most important, adds consistency checks to malloc/free to warn you against some memory allocation errors. 

Unlike for Fortran, the C compiler generates different code when /dbglibs is on, so if you have a mixed-language application you need to make sure that all the projects set this option consistently. Finally (I think), the debug libraries are not redistributable, so if you are building an app to be run on a different computer, be sure to do a Release build or at least turn off /dbglibs consistently.
