Re: [Repast-interest] Repast HPC compile Error (virtual function override)

[Murphy, J. T. <jtm...@an...>]

Kashif,

Try adding 'virtual' before the declaration of setup() in ZombieObserver.h:

virtual void setup(repast::Properties props);

For some compilers this seems to be handled implicitly; for others it must be specified. What compiler are you using? If this adjustment works as I hope then we can correct it in the upcoming releases.

Please let us know if it works- it helps us a great deal to find these problems.

And- regarding this and the rest of our exchanges- Thanks! Your feedback on RepastHPC is very much appreciated.

Best,
John

Subject: [Repast-interest] Repast HPC compile Error (virtual function override)

Hello everyone

Can anybody resolve this build error in Linux environment.

According to our admin, all the required libraries are enabled and this is a coding error. But I am only using the zombie_model provided in the distribution.


Best.
