[Boost 1.85.0] boost/1.85.0: Fail to cross compile using LLVM clang #24981

This issue does seem to be specifically with just the boost recipe. I am able to build |

@av4625 Hello, I believe it could be a misconfiguration. Please, read the example of cross-building in Conan 2.x docs: https://docs.conan.io/2/examples/cross_build/tricore.html I see you are still using Conan 1.x, but that example should work as well. The key is using the configuration Also, consider moving to Conan 2.x when possible. It seems 19 months since its release and Conan 1.x is the way of deprecation. |

I will try and give that a go asap. I currently have cmake-conan incorporated into a fairly big project, which is why I’m stuck on conan 1.x. |

I added this to the conan profile: This didn't help, you can see from the included output that it isn't using the compile flags as it errors saying |
Description
I am unable to cross compile boost using LLVM clang version 18.
I installed LLVM clang using:
When I try to build boost using a separate build and host profile it fails. The header files it can't find are in the sysroot in an expected place.
I am able to build
gtestandnlohmann_jsonusing the same command and profiles. Building the dependencies for boost also seems to work fine.I think it might be a linker issue, like it might be using the wrong one or something, or not using the sysroot properly but not sure.
This is the command to build one file using clang as a cross compiler incase this helps.

I have tried adding this to the host profile as well:

-fuse-ld=lldfrom theC,CXXandLDflags.Steps to reproduce
conan install -r conancenter boost/1.85.0@ -pr:b=default -pr:h=host_profile --update --build missing
