Do you have a patch?

viboes — Thu, 03 Jan 2013 16:14:05 GMT

Please, could you tell me if the warnings appear when you define BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN?

Replying to viboes:

I eliminated Boost form my project and am unable to reproduce the warnings quickly. It will take a several days. Sorry. Please wait. Or may be somebody other will try to reproduce. As far as I remember they happen during Boost build.

Warnings still appears even if i define BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN

Could you please provide me a command line which allow me quickly to reproduce the issue on my set too? Thanks.

#include <iostream>
#include <boost/thread/thread.hpp>
#define BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN
using namespace std;
int main() {
	cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
	return 0;
}

This is the only lines in my file. I included C:\Boost\boost_1_52_0, added this library path : C:\Boost\boost_1_52_0\lib and thoose libraries : boost_system-mgw47-1_52 boost_thread-mgw47-mt-sd-1_52

Thanks.

I remembered that my program was even shorter - just #include <boost/thread/threads.hpp> and main(int,char){}

This gave warnings and one error (I asked about this on StackOverflow).

And I remembered I've just fixed that warnings for my Boost's sources without backup. So, now I'm unable to reproduce the issue because do not have sources.

Hope, now you'll help Boost guys to fix the issue.

But hey! Just noted: seems you have to put define before include. Isn't it?

Therefore, the answer for viboes' question regarding the flag BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN is positive: yes the flag eliminates that warnings.

On 1.54, I would define BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN by default as I don't see any regression on it.

Unfortunately I don't think this merits the change in 1.53 given the advanced state of the release.

Could I close this ticket then?

Yes you can close it ! Thanks again for your help
