Am I missing something or is that error entirely down to code inside Boost.ASIO, nothing to do with cpprestsdk?

Also, if you're going to test bleeding-edge Boost, probably best not to do so against the two-and-a-half year old cpprestsdk v2.9.1!

Am I missing something or is that error entirely down to code inside
Boost.ASIO, nothing to do with cpprestsdk?

After reporting to Boost the issue is now tracked as zaphoyd/websocketpp#794

Also, if you're going to test bleeding-edge Boost, probably best not
to do so against the two-and-a-half year old cpprestsdk v2.9.1!

The issue was noticed via automation but before reporting I did try master branch, from where the above error is quoted.

[garethsb]

@jbeich thanks for the explanation. Looks like the right people are on the case!

It seems I still have this issue on macOS 10.15.4 when trying to compile cpprestsdk, with the following Home-brew installation of boost :

same issue on macOS 10.15.4

[garethsb]

@zeetabit Finally resolved in cpprestsdk 2.10.16, I believe.

[zeetabit]

It works for me, thanks!

[JingweiZhangBoston]

I have this issue on Ubuntu 18.04.4. My boost version is 1.71.0

[c72578]

@JingweiZhangBoston Which version of cpprestsdk and websocketpp are you using?

[JingweiZhangBoston]

@JingweiZhangBoston Which version of cpprestsdk and websocketpp are you using?

@c72578 My cpprestsdk version is 2.10.16, websocketpp version is 0.7.0

[c72578]

@JingweiZhangBoston OK, websocketpp 0.7.0 is not compatible (without patching) with boost 1.71.0.
If you checkout the git version of cpprestsdk, you can use the submodule websocketpp, which is version 0.8.2 and works with boost 1.71.0.
Uninstall websocketpp 0.7.0, then run

git clone https://github.com/microsoft/cpprestsdk.git
cd cpprestsdk
git submodule update --init

websocketpp 0.8.2 will then be in this subfolder:
cpprestsdk/Release/libs/websocketpp
And it will be automatically used, when building cpprestsdk

@JingweiZhangBoston OK, websocketpp 0.7.0 is not compatible (without patching) with boost 1.71.0.
If you checkout the git version of cpprestsdk, you can use the submodule websocketpp, which is version 0.8.2 and works with boost 1.71.0.
Uninstall websocketpp 0.7.0, then run

git clone https://github.com/microsoft/cpprestsdk.git
cd cpprestsdk
git submodule update --init

websocketpp 0.8.2 will then be in this subfolder:
cpprestsdk/Release/libs/websocketpp
And it will be automatically used, when building cpprestsdk

Upgrade websocketpp to 0.8.2 works. Thank you.
