matlab dynamic error C2371: 'char 16_t' : redefinition

[mdv]

Hi all

I try to compile the latest openvibe release, but the building gets stuck with following error:

it seems there is a problem with type conversion. Did anyone encounter this before? or is it specific to our matlab version?

thanks,
maarten

Hi Maarten,

It seems like there is indeed a problem with the matlab box. the build process found matlab but not some other dependencies (libeng and stuff). As I only tested with matlab R2011a and sup, it's possible your R2010a version does not work with the box; never tested...

I suggest you disable the compilation of this box manually.
Modify win32-init_env_command.cmd and delete the line

Code: Select all

echo %OpenViBE_plugin_matlab% >> %OpenViBE_build_order%

near the end of file.

The Matlab box won't be compiled, but hopefully you will be able to build the software.

Have you got access to a newer version of Matlab to test ?

I have MATLAB 2007b and what I have found is that I can
compile the MATLAB filter with older version of OpenVIBE
(in this case, 0.9.0), but in the newest version, I get several
errors.
