MEX Errors #13

Open xueao opened 6 years ago

xueao commented 6 years ago

Hi Loicland: When I tried to compile cut-pursuit with matlab using mex, the following errors occured： ..\cut-pursuit\include\Common.h(38): error C2131: expression is not a constant. ..\cut-pursuit\include\Common.h(38): note: A call to a function that is undefined or a function that is not declared as "constexpr" causes a failure. Do you know how to fix it? thank you!

Hi,

Which version of GCC are you using?

You could also rewrite this part using new if you don't want to change compilers, see this thread. I would rewrite it but I am away for a few weeks so I won't be able to do it myself in the very short term.

same for the Matlab demo code:
