Unhelpful error message when building without checked out submodules about labstreaminglayer

[cboulay]

The repository uses submodules. When you clone it you have to use --recursive, or you'll have to git submodule init && git submodule update

I'm really sorry if that was the likely cause, I'm not used to using Git/Github. Thank you, I will see if this solves my problems.

I built the liblsl64.dll file thanks to your help. However, after placing it in liblsl-Matlab/bin I now receive the following error upon running vis_stream() from MATLABViewer:

Undefined function or variable 'lsl_loadlib_'.

Error in lsl_loadlib (line 65)
hlib = lsl_loadlib_(dllpath);

Error in vis_stream (line 73)
lib = lsl_loadlib();

On line 71 of vis_stream() I notice the following:

try
lib = lsl_loadlib(env_translatepath('dependencies:/liblsl-Matlab/bin'));
catch
lib = lsl_loadlib();
end

Which produces:

Undefined function or variable 'env_translatepath'.

What am I missing? Further help is greatly appreciated.

For some reason the mex files have to be rebuilt for some configurations. In the liblsl-Matlab folder there's a script called build_mex.m that takes care of it. Could you run it and see if it helps?

I tried running build_mex and received a similar error message:

Try changing your working directory (the folder in the long white bar above your editor) to liblsl-Matlab.

Switching to the liblsl directory in MATLAB worked for using build_mex(), and now I can use vis_stream().

Thank you!
