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

Open av4625 opened 2 months ago

av4625 commented 2 months ago

Description

I am unable to cross compile boost using LLVM clang version 18. I installed LLVM clang using:

brew install llvm

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 gtest and nlohmann_json using 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.

/usr/local/opt/llvm/bin/clang++ --target=armv7a-linux-gnueabihf --sysroot=orangepi_sysroot -mfloat-abi=hard -mthumb -march=armv7-a+fp -mtune=cortex-a7 -mfpu=neon-vfpv3 -Wno-psabi -stdlib=libstdc++ -fuse-ld=lld main.cpp -o cross_compile_test

Package and Environment Details

I have tried adding this to the host profile as well: LD=/usr/local/opt/llvm/bin/ld.lld.

I have also tried adding and removing -fuse-ld=lld from the C, CXX and LD flags.

Steps to reproduce

conan install -r conancenter boost/1.85.0@ -pr:b=default -pr:h=host_profile --update --build missing

This issue does seem to be specifically with just the boost recipe. I reduced my projects dependency on boost to be header only and instead included poco for anything I needed from boost that wasn't header only and I am able to successfully build again. So the problem seems to be building boost libraries only.

I am able to build boost/1.86.0 (header only), nlohmann_json/3.11.3, sqlitecpp/3.3.1, poco/1.13.3 and gtest/1.14.0 using the method above including these libraries dependencies. Just not the full boost library.

@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 tools.build:compiler_executables and point the path to your compilers.

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.

av4625 commented 1 month ago

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.

av4625 commented 1 month ago

I added this to the conan profile:

[conf]
tools.build:compiler_executables={'c': '/usr/local/opt/llvm/bin/clang', 'cpp': '/usr/local/opt/llvm/bin/clang++'}

This didn't help, you can see from the included output that it isn't using the compile flags as it errors saying clang++: warning: unknown platform, assuming -mfloat-abi=soft and you can see I set it to hard. This is probably why it can't find std headers either as its probably not using -stdlib=libstdc++.
