Extraction brain mask: multiple definition of () First defined here

[Bram Callewaert]

Hi all

I am using the MEDI toolbox using the README file (windows, Matlab 2019b, MEDI toolbox (updated Jan 15, 2020)). 

I am stuck at the extraction of the brain mask using FSL BET. 

When I use runmex(), as suggested by Junghun in my previous question, (using the Matlab add-on MinGW-w64) i get the following error: 

Error using mex

Does anyone know what the problem might be? 

Kind regards,

Hi Bram,

I have the exact same problem. 

(Windows 10, Matlab R2017b)

A few years later, did you find a way to get around this problem ? 
Or anyone in this group ?

Thanks,

Aurélien

Dear Aurélien 

Look up the definitions of value_string, set_value, print, and config_key in MEDI_toolbox\functions\bet2\functions.cpp. 

Insert the word inline at the beginning of the definition. For example

 

template<> string Option<bool>::config_key() const

becomes

template<> inline string Option<bool>::config_key() const

Let me know if this works.
