Is it possible for "ccall" to call the shared library created by PackageCompiler.jl?

Make sure to follow all the steps

  1. Set the JULIA_DIR environment variable. That should be the folder that contains bin, include, and lib.
  2. The bin folder under JULIA_DIR should be on the system PATH.
  3. To modify the project, I used this main function and needed to add two additional preprocessor directives.
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <julia.h>

int main()
{
    jl_init();
    jl_eval_string("print(sqrt(2.0))");
    jl_atexit_hook(0);
    return 0;
}
  1. Set the project to Debug x64
  2. Using the project Properties dialog, go to C/C++ | General and add $(JULIA_DIR)\include\julia\ to the Additional Include Directories property
  3. Then, go to the Linker | General section and add $(JULIA_DIR)\lib to the Additional Library Directories property.
  4. Finally, under Linker | Input , add libjulia.dll.a;libopenlibm.dll.a; to the list of libraries

I then get the following build log:
