This change breaks the CMake build: https://github.com/boostorg/boost/actions/runs/9594246969/job/26456395308

[pdimov]

Instead of

add_library(Boost::stacktrace ALIAS Boost::stacktrace_windbg)

use

add_library(Boost::stacktrace ALIAS boost_stacktrace_windbg)

and similarly for the other two.

[pdimov]

Also, you need to add CMake jobs to your CI.

[pdimov]

Can this please be fixed? It's breaking my boostorg/cmake CI and interfering with my work.

[leha-bot]

Hello, yes, sorry; hotfix will be ready in no time.
I actually want to ping you to ask about proper boost_install() usage, as I also want to expose it from Boost-config.cmake

#168

@pdimov , may you show the example with CMake CI? I will contribute it also in another PR, thanks in advance.

This might not be easy because boost_install() has never been tested with ALIAS targets and probably doesn't work as-is.

[pdimov]

The Timer CI may be the best starting point

https://github.com/boostorg/timer/blob/develop/.github/workflows/ci.yml#L268-L601

because it's a compiled library (although macos-11 would need to be replaced with macos-14 because macos-11 is going away.)

[leha-bot]

Yes, thanks, will try to play on my own fork with both of them (boost_install() and CI), maybe will come up with some ideas about it. 👍

[pdimov]

For the boost_install() part, maybe the way to do it is to declare boost_stacktrace as an INTERFACE library that links to the corresponding boost_stacktrace_... one. (Boost::stacktrace will be an ALIAS to boost_stacktrace as usual.)

[pdimov]

I'm working on adding CI. Will look into the boost_stacktrace target next.

[pdimov]

Added CMake CI to develop.

Added boost_stacktrace on a branch, but there are weird failures on macos-12 and macos-14. I'm not sure why they happen and what I need to do about them.

macos-12 is just this

/Users/runner/work/stacktrace/boost-root/libs/stacktrace/test/test.cpp(279): test 'boost::stacktrace::stacktrace(1, 1).size() == 1' failed in function 'int main()'
1 error detected.

(https://github.com/boostorg/stacktrace/actions/runs/9617263707/job/26528655980)
whereas macos-14 is more convoluted and probably caused by inlining (https://github.com/boostorg/stacktrace/actions/runs/9617263707/job/26528657050).

[pdimov]

Added the Boost::stacktrace library (now properly installed and tested) to develop.
