Fail to Compile in to DTLS library about asio_dtls HOT 10 CLOSED

The error you get does not show where it actually occurred,
it seems to be in the boost\asio\detail\win_static_mutex.hpp header. But i would suspect
a missing include/define but to be certain it would be good if you had a Verbose build showing
what file is actually compiled.

I noticed in your Makefile you have: -UBOOST_ASIO_WINDOWS
Shouldn't that be a -DBOOST_ASIO_WINDOWS ?

Hi,
Thanks for Immediate response.
I was getting that error while compiling the \boost\asio\ssl\dtls\detail\impl\engine.ipp file. I was getting a bunch of error in boost/asio/detail/win_static_mutex.hpp and win_static_mutex.ipp files.
Below i have shared sample errors.
c:\test\releases\projDTLS\3rdparty\boost\boost\asio\detail\win_static_mutex.hpp(55): error C2039: 'CRITICAL_SECTION': is not a member of '`global namespace'' (compi
ling source file C:\test\Releases\projDTLS\3rdparty\boost\boost\asio\ssl\dtls\detail\impl\engine.ipp) [C:\test\Releases\projDTLS\build\3rdparty\boost\boost\a

st_dtls.vcxproj]

To avoid above error i have added -UBOOST_ASIO_WINDOWS macro. still no efftective.
I have commented out below lines in detail/static_mutex.hpp. Now its compiling succusfully. is this good way or what?

After above library compilation.. now linker error with the library. Please let me know how to link library.

_BIO_free is part of OpenSSL, so you probably don't link it correctly.

I don't have a windows system for building available at the moment (maybe on Monday).
What you could try is the ASIO_HEADER_ONLY define.
Also I have only tested with Boost 1.70 so I'm not certain this
works at the moment.

I have to prepare cmake file without the comment. can you please comment on this.

from asio_dtls.

I have tried to compile asio_dtls using:

• Windows 10
• Visual Studio 2019
• boost 1.72.0
• openssl 1.1.1f

And after fixing the linkage of boost i have the error in

• dtls\src\examples\boost\server\example_boost_server

It seems there is an error in the dtls::acceptor .
If you don't need this functionality you can just disable the server example.
I can't say when i will have a fix as i haven't understood what the cause is,
but i will try to get it fixed.

from asio_dtls.

With the latest Commit (c578c3e) i could successfully compile asio_dtls and the boost examples.

cmake call:
cmake -DOPENSSL_ROOT_DIR=C:\Libraries\openssl-vc -DBOOST_ROOT=C:\Libraries\boost_1_72_0 -DBoost_USE_STATIC_LIBS=ON -Dasio_dtls_use_boost=ON ..

Assuming the libraries are located in the respective Directories and you have a static built Boost.
And .. is the path to the asio_dtls source.

from asio_dtls.

I assume this has been fixed, so I'm closing the issue.
