Hello Julia's fans I am starting studing Julia. As I have some code in Fortran, I really interested in the ccall function to call some specialized code in Fortran.
I wrote a simple function inside a module to do some tests passing a parameter to receive a value from a Fortran value. The Fortran Code is on the file a1.f90 attached I compile using gfortran : gfortran a1.f90 -o a1.o -fPIC -shared For the tests, I created a very simple Julia file test.jl, attached. the module a1.o is on the same directory of test.jl. I invoke using julia test.jl and got error message : julia test.jl +---------------------+ Teste 2: chamando subrotina teste recebendo o resultado no parĂ¢metro b : ERROR: LoadError: MethodError: `convert` has no method matching convert(::Type{Int64}, ::Tuple{Int64}) This may have arisen from a call to the constructor Int64(...), since type constructors fall back to convert methods. Closest candidates are: call{T}(::Type{T}, ::Any) convert(::Type{Int64}, !Matched::Int8) convert(::Type{Int64}, !Matched::UInt8) ... in anonymous at no file in include at ./boot.jl:261 in include_from_node1 at ./loading.jl:320 in process_options at ./client.jl:280 in _start at ./client.jl:378 while loading /discolocal/abimael/simulacoes/testes/julia/workspace/fortran/test.jl, in expression starting on line 6 I write this post asking you for help because I did several changes, trying to figure out what is wrong, but unfortunely I am not able to find a solution. I had changed the type of the parameter in the fortran code, but it does not work. It seems that I am passing parameter wrongly, but by the information of ccall, I should pass using tuples. So,please where am I wrong or doing wrong ? Thanks in advance
