How to rebuild lld of NDK 21.1.6352462 for linux x86

[arderbud]

what have i done?

exec command ./ld.lld --version, i got the build commit:

LLD 9.0.8 (/buildbot/tmp/tmpyQwgD_ e0caee08e5f09b374a27a676d04978c81fcb1928) (compatible with GNU linkers)

so i checkout code from https://github.com/llvm/llvm-project/tree/e0caee08e5f09b374a27a676d04978c81fcb1928

and build lld
cmake -G Ninja ../llvm \ -DCMAKE_BUILD_TYPE=Release \ -DLLVM_ENABLE_PROJECTS="lld" \ -DLLVM_TARGETS_TO_BUILD="X86;AArch64;ARM" \ -DLLVM_INCLUDE_TESTS=OFF \ -DLLVM_INCLUDE_EXAMPLES=OFF \ -DLLVM_INCLUDE_DOCS=OFF \ -DCMAKE_OSX_ARCHITECTURES=x86_64 \

The problem I encountered

when i use the lld build by myself,I found that the symbols that could be exported before are no longer available in the compiled SO，I suspect that my compilation command is different from NDK, so I'm here to ask how LLD in NDK is compiled

The upstream build doesn't really work for multi-arch builds. CMake just isn't built to handle that. You have to run our build. See https://android.googlesource.com/toolchain/llvm_android/+/mirror-goog-main-llvm-toolchain-source/README.md
