c++ - libpng warning in Eclipse -

-

i on ubuntu 12.04 lts using eclipse 3.7.2 trying use mathgl. simple, c++ looks like:

#include <iostream> #include <mgl2/mgl.h>  using namespace std;  int main() {   mglgraph gr;  gr.fplot("sin(pi*x)");  gr.writepng("test.png");  return 0; }

when run following warning :

libpng warning: application built libpng-1.2.46 running 1.5.13

and test.png cannot displayed.

any ideas on how fix it?

thanks!

you have re-build app use libpng-1.5.13. built 1.2.46. or read release notes 2 versions , determine supported in 1.2.46 , stay within boundaries. must trying use functionality in lidpng not in 1.2.46

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
