release 0.8.0 fails to build on linux

[ImOnALampshade]

Importing yaml-cpp via vcpkg is broken due to this.

When trying to build locally, the following error occurs:

The issue here seems to have been fixed in the master branch. If I clone my own version and build the master branch, everything compiles cleanly.

However, if I git checkout 0.8.0, the build fails with the same errors.

Perhaps a simple version tick would fix this issue?

I just ran into the same thing. I fixed it by

sed -i -e 3i\"\#include <cstdint>\"  src/*.cpp

Considering that a commit seems to have been made 2 months ago, is it time for a new release?

Hello, I experiment the same issue than @ImOnALampshade. I saw the issue was fixed in August 2024. The master branch includes the fix but not the release tag ( 0.8.0 ). Is possible to release a micro version (e.g. 0.8.1 ) ? This will fix the issue for a lot of people.

Building from the master branch worked fine on Slackware64-current using GCC 15.2
