I am trying to cross-compile a .go file for the GTK binding package Linux => Windows and can't figure it out. Tried going the route of setting up MSYS on Win but it was god-awful.
I looked for a Docker image but there is none.

As part of an engineering project for school we were asked to make a program that could play a simple song. We have created the code based on the example ToneMelody for the arduino program. we get an error after all of are notes are listed that highlights red on both are music_code file and our pitches.h file. However, on our pitches.h file the error stops at #define Note_AS3 233 it says exit status 1 expected declaration before '}' token. What does this error mean and how exactly can we fix it because the example tonemelody program works fine?
So, there's a number of errors in your posted sketch which would stop it from compiling.
NOTE_A3 is referenced but not defined
On the very first line of the definition of int melody[], there is no comma between NOTE_GS4 and NOTE_A4
On the third line of the definition of int noteDurations[], you are missing a comma between 8 at the end of the line, and the next element
If you correct all three of these, the code should compile just fine. You should, however, receive more than just one error like you describe from the Arduino IDE. I received notably more, which allowed me to at least figure out where each problem was. If you don't see it in the Arduino error box, you should at least see it through the command line output, which will allow you to track these down in the future.
I have a IS_TESTING boolean flag indicating whether the current build is testing
I want to hide NSLog if IS_TESTING is NO. And it should also support a single string parameter.
This is CCLog from cocos2d:
#define __CCLOGWITHFUNCTION(s, ...) \
NSLog(#"%s : %#",__FUNCTION__,[NSString stringWithFormat:(s), ##__VA_ARGS__])
#define __CCLOG(s, ...) \
NSLog(#"%#",[NSString stringWithFormat:(s), ##__VA_ARGS__])
#if !defined(COCOS2D_DEBUG) || COCOS2D_DEBUG == 0
#define CCLOG(...) do {} while (0)
#define CCLOGWARN(...) do {} while (0)
#define CCLOGINFO(...) do {} while (0)
#elif COCOS2D_DEBUG == 1
#define CCLOG(...) __CCLOG(__VA_ARGS__)
#define CCLOGWARN(...) __CCLOGWITHFUNCTION(__VA_ARGS__)
#define CCLOGINFO(...) do {} while (0)
#elif COCOS2D_DEBUG > 1
#define CCLOG(...) __CCLOG(__VA_ARGS__)
#define CCLOGWARN(...) __CCLOGWITHFUNCTION(__VA_ARGS__)
#define CCLOGINFO(...) __CCLOG(__VA_ARGS__)
#endif // COCOS2D_DEBUG
This is what I write:
#define __CCLOG(s, ...) \
NSLog(#"%#",[NSString stringWithFormat:(s), ##__VA_ARGS__])
#if IS_TESTING == 0
#define CCLOG(...) do {} while (0)
#elif IS_TESTING == 1
#define CCLOG(...) __CCLOG(__VA_ARGS__)
#endif
use:
CCLOG(#"single string parameter");
CCLOG(#"string format %#", #"parameter");
It runs without crash, but nothing gets printed out.
EDIT:
#define IS_TESTING YES
I have tried
#if IS_TESTING == YES/NO, but still the same as 0/1, nothing gets printed out
Your code works perfectly. But IS_TESTING must be defined before you start the __CCLOG definition stuff.
So, in the .pch file, I wrote:
#define IS_TESTING 1
#define __CCLOG(s, ...) \
NSLog(#"%#",[NSString stringWithFormat:(s), ##__VA_ARGS__])
#if IS_TESTING == 0
#define CCLOG(...) do {} while (0)
#elif IS_TESTING == 1
#define CCLOG(...) __CCLOG(__VA_ARGS__)
#endif
And later:
CCLOG(#"%#", #"YES");
Since I have defined IS_TESTING to 1, we log. If I change it to 0, we don't.
As a bonus, I'll show you what I do. It's much simpler. Here it is:
#define MyLog if(0); else NSLog
This makes MyLog equivalent to NSLog. To turn off logging, change 0 to 1.
I just upgraded to cocos 2.1, and am seeing a ridiculous amount of logging to the console, such as:
2013-09-18 23:15:38.120 Notes and Clefs[842:907] cocos2d: deallocing <CCSprite = 0x1182aa0 | Rect = (816.00,640.00,32.00,64.00) | tag = -1 | atlasIndex = -1>

etc..
From looking at the code, I see:
#if !defined(COCOS2D_DEBUG) || COCOS2D_DEBUG == 0
#define CCLOG(...) do {} while (0)
#define CCLOGWARN(...) do {} while (0)
#define CCLOGINFO(...) do {} while (0)
#elif COCOS2D_DEBUG == 1
#define CCLOG(...) __CCLOG(__VA_ARGS__)
#define CCLOGWARN(...) __CCLOGWITHFUNCTION(__VA_ARGS__)
#define CCLOGINFO(...) do {} while (0)
#elif COCOS2D_DEBUG > 1
#define CCLOG(...) __CCLOG(__VA_ARGS__)
#define CCLOGWARN(...) __CCLOGWITHFUNCTION(__VA_ARGS__)
#define CCLOGINFO(...) __CCLOG(__VA_ARGS__)
#endif // COCOS2D_DEBUG
And I set COCOS2D_DEBUG = 0, but I still get the same verbose logging...
I have Cocos2D in my project as a static library .a file.. Is it possible that this .a already has a macro/constant defined at level 2 or something, and that's why I'm seeing it not make any difference?
Can anyone recommend a way to turn this off?
Yes, when the static library is compiled using the Debug scheme, it'll print all these debug messages out. Try recompiling the static library with the COCOS2D_DEBUG preprocessor macro set to 1.
Why are you adding it as a static .a library though? I just add the cocos2d-ios.xcodeproj to my own project and add libcocos2d.a to Build Phases under Link Binary with Libraries. That way it'll automatically recompile cocos2d whenever a change occurs.
Running the code below to write 1 GB in global memory in the NVIDIA Visual Profiler, I get:
- 100% storage efficiency
- 69.4% (128.6 GB/s) DRAM utilization
- 18.3% total replay overhead
- 18.3% global memory replay overhead.
The memory writes are supposed to be coalesced and there is no divergence in the kernel, so the question is where is the global memory replay overhead coming from? I am running this on Ubuntu 13.04, with nvidia-cuda-toolkit version 5.0.35-4ubuntu1.

I had the impression that global_store_transation could not be lower than gst_request. What is going on here? I can't ask for both events in the same command, so I had to run the two separate commands. Could this be the problem?
Strangely, the API profiler shows different results with perfect coalescing. Here is the output, I had to run twice to get the proper counters:
$ cat config.txt

inst_executed

_Z12kernel_writePjj,7807.584,7831.000,1.000,557058
Here gst_request and global_store_transactions are exactly the same, showing perfect coalescing. Which one is correct (nvprof or the API profiler)? Why does NVIDIA Visual Profiler says that I have non-coalesced writes? There are still significant instruction replays, and I have no idea where they are coming from :(
Any ideas? I don't think this is hardware malfunctioning, since I have two boards on the same machine and both show the same behavior.
