The compilation of a C++ program involves three steps: Preprocessing: the preprocessor takes a C++ source code file and deals with the #includes, #defines and other preprocessor directives. The output of this step is a “pure” C++ file without pre-processor directives. Compilation: the compiler takes the pre-processor’s output and produces an object file from it. … Read more
How about saving user’s code somewhere in the device as .java file and then running shell command for compiling file and processing user’s code. refere below code try{ Process su = Runtime.getRuntime().exec(“su”); DataOutputStream outputStream = new DataOutputStream(su.getOutputStream()); outputStream.writeBytes(“screenrecord –time-limit 10 /sdcard/MyVideo.mp4\n”); outputStream.flush(); outputStream.writeBytes(“exit\n”); outputStream.flush(); su.waitFor(); }catch(IOException e){ throw new Exception(e); }catch(InterruptedException e){ throw new Exception(e); … Read more
Check http://en.cppreference.com/w/cpp/language/eval_order especially the part which discusses “Undefined behavior”. Basically it’s not a bug in the compiler. The language says what you’re doing is undefined.
Circular dependencies are just bad design. If you feel the urge to have a child/owned object “know about” its parent/owner, you should pass the child a std::function instead of a full reference to the owner.
