I am writing tot his forum as a friend of mine who has been helping me get the example couette script up and running found a problem with the fftw_loadwisdom function. Commenting it out allows the program to run but leaving it in results in the following error :
terminate called after throwing an instance of ‘std::logic_error’
what(): basic_string::_M_construct null not valid
Aborted (core dumped)
We were not sure of the significance of this function and I am wondering is it just better to leave it out altogether? Also, is there an easy way to link the chflow library as I am currently linking all the cpp and h files by hand meaning it takes longer than it should to compile.
