Boost C++ Libraries: Ticket #12387: automatic lib link

Andrey Semashev — Wed, 10 Aug 2016 11:56:08 GMT

I can't reproduce this with the latest develop branch. My MSVC version is 19.00.24210 and the test code compiles and links fine:

#include <boost/log/trivial.hpp>
#include <boost/log/sources/severity_logger.hpp>
#include <boost/log/sources/record_ostream.hpp>
#define X 0
int main()
{
    return 0;
}

The command line is:

cl -I. /EHsc /MD -D_DEBUG test_vc14_hang.cpp /link /LIBPATH:stage/lib

If you can reproduce this with the develop branch from git then please provide the source code and compiler command line to reproduce. Also please provide the full compiler version.

Lastly, I suggest you report this to Microsoft as hanging compiler is certainly a compiler bug.

Pls. put the define before the includes...

That makes compilation to fail because X is used as a template parameter in boost::shared_ptr implementation. No compiler hang.

You are right... defining X just gave a rightful error, the hang happened when I have put before the includes: #define X 0 #define Y 1

this happened even in the compilation before the link

I work with Visual Studio 2015 with the default toolset v140

status changed; resolution set

status new → closed
resolution → wontfix

With two defines the compiler outputs errors and then hangs.

I'm sorry, but I don't think I will be able to work around it in the library, especially given that the test code is not supposed to compile in the first place. I suggest you report this to Microsoft so that they fix the compiler hang.

Thanks for looking into it. BTW I checked on my mac as well and the compiler doesn't hang, so I agree it's probably MS issue.
