[Octave-bug-tracker] [bug #51585] mex.h not compatible with Matlab implementation

[Rik]

Follow-up Comment #1, bug #51585 (project octave):

Which version of Matlab are you using?  Current versions do not seem to
require the extern declaration.  I'm basing that on some help text that I
could find online
(https://www.mathworks.com/help/matlab/matlab_external/compiling-c-mex-files-with-mingw.html).
 This Stack Overflow article also looked useful
(https://stackoverflow.com/questions/35134314/mex-function-unresolved-external).
 In the resolution, the author doesn't need to use extern declarations at all,
but interestingly you have to worry about file naming conventions a lot.

If you look at the implementation of mex.h that Octave uses, it automatically
accomodates compilation with either C or C++.  See these lines:


#if defined (__cplusplus)
extern "C" {
#endif


I would think that Matlab does something similar now.
