Build error with some boost libraries

[jmcmon]

Hi Antony,

I've been able to get a substantial amount of the build completed, but it fails towards the end of the boost build.
I can see that's item 21 of 29, so that looks like good progress so far.

When I reran the conan install command, the output was naturally more succinct and is shown below.

Thanks,
John

Hi John,
From a first research it seems a specific build issue of MacOS for boost:
conan-io/conan-center-index#4097
Cheers,
Gianmario

[Twon]

Hey chaps,

I've definitely seen this this issue locally on my Mac, I may need to dust if off to investigate properly. However, the CI does build this project for MacOs so we should treat that as the source of truth: https://github.com/Twon/Morpheus/actions/runs/6252622058/job/16976273577#step:15:14

However, the CI only builds apple-clang version 14 so there may be further failures. However, the main thing I see is that the Conan profile on CI sets the C++ version to 20 which your profiles does not do. The profiles on CI is:

[settings]
arch=x86_64
build_type=Debug
compiler=apple-clang
compiler.cppstd=20
compiler.libcxx=libc++
compiler.version=[14](https://github.com/Twon/Morpheus/actions/runs/6252622058/job/16976273577#step:15:15)
os=Macos
[conf]
tools.cmake.cmaketoolchain:generator=Ninja Multi-Config

It is specifically this line that is the important one:

compiler.cppstd=20

Without that boost will build under the default version of C++ which is C++03. However, boost generally dictates that library must be C++11 compliant (which is what I assume most build as) but there are also exceptions allowed, so some may only build under C++14/17 which may be the reason that there are some library refusing to build. Certainly these library have built on the CI. Note that most of the time on the CI the library are not build, but fetched from a cache by this step:

Morpheus/.github/workflows/cmake.yml

Line 58 in 31ec023

- name: Cache Conan data

If you actually want to see what happens when building these libraries then you need to find a run on the CI when they were built. Or delete the cache and rerun the CI step so they rebuild (this will take 45 minutes or so which is why we cache to begin with). John, I have just added you as a collaborator for this project so you have this ability once accepted.

Hi all,
I've been looking into this today, including on the conan issues page and haven't got to the bottom of it yet.
My compiler.cppstd is set to 20 in my default profile under .conan2, but I assume there's a bit more to solving this issue.

The CI log I found is at https://github.com/Twon/Morpheus/actions/runs/5985550044/job/16237752886

I can see that the boost libraries built successfully on CI.
On the readme conan install command, both host and build are set to use gcc.
In CI it uses apple clang (the default)

conan install "/Users/runner/work/Morpheus/Morpheus" --build missing -pr:b default -c tools.cmake.cmaketoolchain:generator="Ninja Multi-Config" --build catch2/3.3.2

======== Input profiles ========
Profile host:
[settings]
arch=x86_64
build_type=Release
compiler=apple-clang
compiler.cppstd=20
compiler.libcxx=libc++
compiler.version=14
os=Macos
[conf]
tools.cmake.cmaketoolchain:generator=Ninja Multi-Config

Profile build:
[settings]
arch=x86_64
build_type=Release
compiler=apple-clang
compiler.cppstd=20
compiler.libcxx=libc++
compiler.version=14
os=Macos

So, I decided to do the following and set both to the default profile:

(.venv) bash-3.2$ conan install ./ -pr:h .conan2/profiles/default -pr:b .conan2/profiles/default --build missing

======== Input profiles ========
Profile host:
[settings]
arch=x86_64
build_type=Debug
compiler=apple-clang
compiler.cppstd=20
compiler.libcxx=libc++
compiler.version=15
os=Macos

Profile build:
[settings]
arch=x86_64
build_type=Debug
compiler=apple-clang
compiler.cppstd=20
compiler.libcxx=libc++
compiler.version=15
os=Macos

This got me a lot further and build boost successfully.

Looks like it fell over trying to get details of the linker.
using --version doesn't work with ld:

I'm still digging, but wanted to provide an update.
Thanks,

Hi John,
In Linux I have also ld -V command which is showing the version. Don't you have in MacOS the man pages? If in bash you write man ld is not showing anything?

Hi Gianmario,
yes I've got output for man ld on my Mac and I use bash as my shell.
Only ld -v returns version info for me. Neither ld -V nor ld --version are accepted.

The ld man page states:
-v Prints the version of the linker.

@jmcmon I'm closing this as from discussing this with you directly I believe you got past this step and got it building correctly. If I am incorrect then please reopen and we can solve it.
