I am currently trying to create a unittest for a function I have defined in my shared fortran library. This function receives an integer value and inserts it into a previously allocated and declared array of a specific fortran type (the equivalent to a c++ struct in fortran) My julia code looks lik…

[image] dmmpie: param_pointer = cglobal(param_sym, Ptr{jul_param}) One possible here: the type should probably just be jul_param because returning a pointer to the global is part of what cglobal does. (Btw, it’s conventional to capitalized types in Julia.) I don’t really understand the Fortra…

changing this line to param_pointer = cglobal(param_sym, jul_param) still produces a segmentation fault, is that what you meant?

That is what I meant. As I said, I don’t really understand what the Fortran code is doing, so it’s hard to give any further help. If you had a comparable example in C, I’d be able to help.

It’s really the same as creating a global struct and a global array of that struct in c, and having a function that takes an integer which refers to the index of the global struct array. During this array access a segmentation fault occurs, so I am trying to figure out how to properly assign this gl…
