Asio 1.33.0 has this change:

  • Removed deprecated alias io_service.

This breakes compilation of Wt when compiled using WT_ASIO_IMPLEMENTATION="standalone"

Hello Stefan,

I believe this was resolved in #13361 (where various fixes were applied). The Github master branch should contain the latest of these. I am able to build Wt using standalone Asio 1.33.0.
Before I reject the ticket (denoting no implementation changes are attached to it), can you verify this?

Best,
Matthias

Hi Matthias,

I've tested compilation of current release Wt 4.12.0 using Clang and Windows 10 with WT_ASIO_IMPLEMENTATION="standalone", with Asio library version 1.34.2-1.

Compilation fails with this error:

I've downgraded my environment back to Asio 1.30.2-1. This compiles fine with Wt 4.12.0 and previous Wt-versions.

(Though, currently I'm not able to use any newer version than Wt 4.11.1 due to https://redmine.emweb.be/issues/13861, could you PLEASE please look into this issue?)

Thanks,
Stefan
