I am trying to write a User-defined Model in C++ for FLAC in Visual Studio Express 2010 c++. Initially, I am trying to run(debug and build) the built-in Strain-softening Model based on the Mohr-Coulomb criterion (Available in FLAC 8.0) by changing its name only from 'ssoft' to 'i_ssoft'. However, I am getting the following error msg:-
1>------ Build started: Project: i_ssoft, Configuration: Debug x64 ------
1> modeli_ssoft.cpp
1> Creating library C:\Program Files\Itasca\FLAC800\PluginFiles\Models\modeli_ssoft\i_ssoft\i_ssoft.lib and object C:\Program Files\Itasca\FLAC800\PluginFiles\Models\modeli_ssoft\i_ssoft\i_ssoft.exp

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
From the error code, it is clear that I need to add models::ConstitutiveModel::getPluginName library which I have tried (a screenshot is attached), but still, I am getting the same error.
Anyone, please suggest to me any appropriate solution for my problem. Kindly, inform me if you need any further information from my end.
I would recommend to ask this Q at Stack Overflow community too:

Dear Anton Vrdoljak,
I have already posted this question in StackOverflow.
Thank you for your interest in my question.
hi,
to assign it a value in the main function, the linker doesn't find the symbol and may result in an “unresolved external symbol” or “undefined reference”. The way to fix this error is to explicitly scope the variable using '::' outside the main before using it.o fix this issue, add the /NOENTRY option to the link command. This error can occur if you use incorrect /SUBSYSTEM or /ENTRY settings in your project. For example, if you write a console application and specify /SUBSYSTEM:WINDOWS, an unresolved external error is generated for WinMain.
