[package] Boost/1.85.0: Cannot compile for Android

[cjserio]

Description

I'm experiencing two issues. The first is that when I try to compile with the profile included in this report, I get these assembly errors:

libs/context/src/asm/make_arm64_aapcs_elf_gas.S:61:5: error: unknown use of instruction mnemonic without a size suffix
    and x0, x0, ~0xF
    ^
libs/context/src/asm/make_arm64_aapcs_elf_gas.S:64:17: error: unknown token in expression
    sub x0, x0, #0xb0
                ^
libs/context/src/asm/make_arm64_aapcs_elf_gas.S:68:16: error: expected ']' in brackets expression
    str x2, [x0, #0xa0]
               ^

    adr x1, finish
    ^~~
libs/context/src/asm/make_arm64_aapcs_elf_gas.S:73:16: error: expected ']' in brackets expression
    str x1, [x0, #0x98]
               ^
libs/context/src/asm/make_arm64_aapcs_elf_gas.S:75:5: error: unknown use of instruction mnemonic without a size suffix
    ret x30
    ^
libs/context/src/asm/make_arm64_aapcs_elf_gas.S:79:13: error: unknown token in expression
    mov x0, #0
            ^
libs/context/src/asm/make_arm64_aapcs_elf_gas.S:81:5: error: invalid instruction mnemonic 'bl'
    bl _exit
    ^~

The second issue is that if I disable all of the components (such as context) to get past these error and get boost to compile, when my android app tries to link, I still get these errors:

    ld: error: undefined symbol: boost::archive::detail::basic_oarchive::save_object(void const*, boost::archive::detail::basic_oserializer const&)
    >>> referenced by oserializer.hpp:260 (/Users/me/.conan2/p/b/boostcfd77fc990e6b/p/include/boost/archive/detail/oserializer.hpp:260)

I've made sure the linker log is showing that I'm linking against the serialization library. The library exists in the proper location...it just doesn't seem to accept the library for some reson.

I also ran into this today. According to the Conan documentation, this should work.

It looks like b2 uses /usr/bin/clang instead of the cross-toolchain. This becomes evident when trying to build boost without native clang installed (which fails early). When explicitly adding the location of the NDK's clang to PATH, it will still produce the error you mentioned (using the correct compiler this time), because clang infers the target architecture from its own filename (defaulting to the host). b2 must call clang via the aarch64-linux-android24-clang symlinks instead.

In summary, my workaround is to add this section to my Conan profile:

[buildenv]
PATH+=(path)<NDK_PATH>/toolchains/llvm/prebuilt/linux-x86_64/bin/
CC=aarch64-linux-android24-clang
CXX=aarch64-linux-android24-clang++

Ideally, Conan should either infer these automatically, or the documentation should be fixed to provide a fully functional Conan profile.

EDIT: I changed PATH= to PATH+=(path) to ensure the NDK binaries path gets appended to PATH rather than replacing it. ((path) is a magic string recognized by Conan to handle this appropriately.)

[uilianries]

You have to consider there is no B2 generator available in Conan (there is an open PR for that). So, any customization should be listed in the Boost recipe directly. When using android-ndk, those extra variables are configured already, including the compiler: https://github.com/conan-io/conan-center-index/blob/master/recipes/android-ndk/all/conanfile.py#L300

So, in case using android-ndk as tool requirement, Boost will be built nicely for Android. Otherwise, you should configure everything manually in your recipe:

conan create all --version=1.85.0 -pr:b default -pr:h android

I would not see it as a bug, but a misconfiguration from your environment. Please, add tools.build:compiler_executables to you profile, pointing the expected compiler for Android.

[neobrain]

@uilianries Thanks for the reply!

I would not see it as a bug, but a misconfiguration from your environment. Please, add tools.build:compiler_executables to you profile, pointing the expected compiler for Android.

Makes sense, though this would be a documentation bug then. cjserio and I were just copying the Conan documentation. Any chance a functional profile could be listed on that page?

In fact, mentioning CCI's android-ndk package there would also be useful, though personally I would prefer an example that works with a manually installed NDK. So ideally we'd have both: One example profile that works with manual installs, and a simpler one that uses android-ndk as a tool requirement?

[cjserio]

Yes thank you so much! I was just going to comment that the docs make no mention of using the NDK as a tool_requires. I was following the docs and pointing the path to my local NDK path which was really clunky because other developers and our CI/CD runners have it installed in different locations. Changing my profile to:

[settings]
arch=armv8
os=Android
os.api_level=24
compiler=clang
compiler.version=14
compiler.libcxx=c++_static
compiler.cppstd=20

[tool_requires]
android-ndk/r25c

has made this much simpler and of course Boost builds properly now.

@cjserio @neobrain Thank you for your feedback! Indeed we discussed about Android examples in the documentation this morning in a meeting. Yes, the documentation can be improved and adding hint about those exceptional cases. Thank you again for giving your thoughts.

@uilianries You said

I would not see it as a bug, but a misconfiguration from your environment. Please, add tools.build:compiler_executables to you profile, pointing the expected compiler for Android.

I didn't notice it until now as I didn't need that to properly compile Boost. All I needed to do was stop hard coding my NDK path and just use the tool_requires with the android-ndk, but now I'm trying to compile freetype/2.13.2 on Android and it's failing because meson is sticking a sys_root path in front of all of my cached conan include paths so nothing's working.

I don't mean to hijack this topic but can you either explain more about this compiler_executables or offer a working and complete example of what an Android profile should look like?
