[julia-users] library called by ccall

Hello colleagues, i'm trying to debug a strange case where ccall-s by julia fail (with an error message from the called function) and the implementation in C succeeds. My first guess is, that actually different versions of a libXXX.so are called. How can i read which library julia is accessing?

[julia-users] associative property of export/include/import?

Hello colleagues, i was for some time under the impression, that the exact sequence of imports do not matter (let's say, i hoped) as the definitions of types and functions are cumulative, modules should be self contained and use require where needed. Today: lobi@maroon:~/juliarepo$ ../julia/j
