in Mopub-SDK for iOS.there is an error in calling "mp_safe_block" method.
Macro definition:
// Macros for dispatching asynchronously to the main queue
#define mp_safe_block(block, ...) block ? block(__VA_ARGS__) : nil
Called as:
mp_safe_block(complete, NSError.sdkInitializationInProgress, nil);
Error message:
Left operand to ? is void, but right operand is of type 'nullptr_t'
maybe this error has nothing to do with the SDK itself. how to fix it ?
PS:
that sdk code run correctly in a new xCode project created by myself. but there is an error in a Xcode-project builded by MMF2(clickTeam fusion)
and this xCode-project version is too old. I updateded setting of Xcode.but it still an error.
I have been getting a massive error recently, upon Running any of my flutter applications in Intellij, Visual Studio, etc. I cannot perform git functions because of it either. Any help would be greatly appreciated.

It's honestly a little hard to tell what's going on from just that error message. Do any errors show up in intellij before you build?
The only things I can think of are:
your flutter installation might be corrupted. You could try deleting and re-installing
your build directory might have something wrong. Try running flutter clean before building again
your libraries aren't being included properly. I'd assume this would show up in intellij, but maybe the paths are set differently there? Check Project Structure -> Libraries and see where the paths are set there.
(related to first) you might have multiple instances of flutter on your computer. If intellij is using one while the command line is using another that could potentially cause problems.
If your app happens to be open-source, or you're able to make a new app with the minimum amount of changes to reproduce the error, that would help significantly with diagnosing the problem =).
I'm trying to port some existing code that uses boost into native-client.
I compiled boost according to the instructions here: https://code.google.com/p/naclports/wiki/InstallingSDL (with boost instead of sdl), and tried injecting some boost code into one of the examples.
I was successfully able to use a boost::shared_ptr by editing examples/api/socket/socket.cc by including the header and adding a simple test method:
#include <boost/shared_ptr.hpp>
The test method:
void ExampleInstance::test_shared_ptr() {
boost::shared_ptr<std::string> test_ptr(new std::string("hi"));
PostMessage(test_ptr->c_str());
}
Invoking this method from the constructor results in a "hi" appearing on the console when loading the page you can reach by running "make serve".
Although I'm deeply impressed that this much works, my app uses boost::thread and boost::asio, and there I ran into trouble. In pepper_34, if I add:
#include <boost/threads.hpp>
I get these compilation errors, just by including that file:
~/nacl_sdk/pepper_34/examples/api/socket$ make

make: *** [newlib/Release/socket_x86_32.o] Error 1
(Side Note: I don't think the CHROME_PATH warning at the top is causing these errors, since I get the same warning for the examples even without my edits, but the examples still work. I imagine it's because I'm building on a vm without chrome installed (or a window manager in which to run it), since I had to use linux to build boost according to the error message the boost build process gave when I tried building it on OSX. The error messages suggest this interferes with "make run_package", but otherwise the examples run properly under "make serve", and can be tested from a different machine, using chrome to access the pages. I'm writing this question while waiting for chromium-browser to install, in hopes I can confirm that theory.)
In case it matters, I'm running Ubuntu 12.04.
My questions:
Is there a previous pepper version in which somebody has successfully used boost::asio and/or boost::threads?
Has anyone encountered this problem and discovered a workaround?
Try building the glibc build of boost instead of newlib. You can do this by running:
TOOLCHAIN=glibc make boost
from the naclports directory.
It seems that the newlib build of boost doesn't support many boost libraries:

I am getting the following error in my VC++ COM project. What is the problem in linking the lib files here?
Error 4 error LNK2019: unresolved external symbol _BVUOpen#8 referenced in function "unsigned int __stdcall AFunc(void *)" (?AFunc##YGIPAX#Z) CBillAcceptor.obj BillAcceptorCOM
Here are the explanation of the LNK2019 error : MSDN.
Look for a problem of definition about BVUOPen symbol ! The problem si inside the method AFunc Maybe, you haven't declare it correctly or haven't link the library or haven't export the symbol...
Probably, you need to link against some external library that contains the object code for the BVUOpen function. The name of that library is not obvious from your error message, but it should be possible to work out from the documentation you are coding from.
