Looks like it's just missing includes. Try adding:

#include <mutex> #include <condition_variable>

@theuni strange, it does not help. Same issue.

any update for this issue?

Does #8653 fix it for you ?

Thanks for reply. When I did: sudo update-alternatives --config x86_64-w64-mingw32-gcc

It seems missing " x86_64-w64-mingw32-gcc files /usr/bin/x86_64-w64-mingw32-gcc-5-posix "

How to install posix version of x86_64-w64-mingw32-gcc on ubuntu?

Which version are you on ? On Ubuntu 16.04 you just need to install the toolchain:

sudo apt-get install g++-mingw-w64-i686 mingw-w64-i686-dev g++-mingw-w64-x86-64 mingw-w64-x86-64-dev

sudo update-alternatives --config x86_64-w64-mingw32-gcc

Press <enter> to keep the current choice[*], or type selection number: 1 update-alternatives: using /usr/bin/x86_64-w64-mingw32-gcc-posix to provide /usr/bin/x86_64-w64-mingw32-gcc (x86_64-w64-mingw32-gcc) in manual mode update-alternatives: warning: skip creation of /usr/bin/x86_64-w64-mingw32-gcc-5 because associated file /usr/bin/x86_64-w64-mingw32-gcc-5-posix (of link group x86_64-w64-mingw32-gcc) doesn't exist

I got this warning message! How to fit it?

On my side I did not tried again since I posted this error. It is very problematic because most of my tests are done on windows, but get busy on other stuff those last days. I'll test again later.

You'll need version 4.7 or later of mingw/gcc at least for those definitions. Which version are you using?

@sstone you are the man, #8653 fixed my issue.

That is the version of gcc

@wbchen99 this is just a warning, you should be able to select the posix compilers and cross-build bitcoind.exe and bitcoint-qt.exe. Does it work ? If it does, did you test the compiled binaries ?

@sstone Sorry for late reply. I still met same problem. I tried previous version of "depends" directory and it worked fine for bitcoin 12.99. Same environments , gcc, g++ and libs. Not sure for these? Could you help?

There are multiple serious issues with bitcoin core and newer mingw compilers, see #8653. For now the only recommendation I can make is to use an Ubuntu Trusty VM for building as is used for gitian and travis.

Sorry to bring that old topic back up, but is there maybe already a solution for this?

I have the same issue compiling the bitcoin client under Debian Stretch using mingw-w64.

I'm using the default packages from Debian stretch repository. And I also tried to switch to posix version with

$ update-alternatives --config i686-w64-mingw32-gcc
$ update-alternatives --config x86_64-w64-mingw32-gcc

but the error still happens after cleaning and building everything again.

Solved the issue.

Bitcoin uses g++, not gcc

$ sudo update-alternatives --config x86_64-w64-mingw32-g++

then select "2" for switching to posix and that's it. Cleaning the environment or rebuilding dependencies were not necesseary.

I can confirm that

sudo update-alternatives --config x86_64-w64-mingw32-g++

solved it for me as well.

I have GCC 5.3.1, and those are enabled:

• 0 /usr/bin/x86_64-w64-mingw32-g++-win32 60 auto mode 1 /usr/bin/x86_64-w64-mingw32-g++-posix 30 manual mode 2 /usr/bin/x86_64-w64-mingw32-g++-win32 60 manual mode

where 0 was selected. (win32). It seems not to use posix, so just select the g++-posix edition.

After that it compiled successfully.
