Hi, I'm trying (and failing) to cross-build lldb according to these instructions <https://lldb.llvm.org/resources/build.html#example-1-cross-compiling-for-linux-arm64-on-ubuntu-host>.
My cmake command line: cd /workspace/build/lldb && /usr/bin/cmake -DLLVM_VERSION_SUFFIX=-custom -DLLVM_PARALLEL_LINK_JOBS=1 "-DLLVM_ENABLE_PROJECTS=clang;libcxx;lldb" "-DLLVM_TARGETS_TO_BUILD=X86;AArch64;ARM" -DLLVM_ENABLE_TERMINFO=FALSE -DLLVM_ENABLE_LIBXML2=FORCE_ON -DLLDB_RELOCATABLE_PYTHON=TRUE -DLLDB_DISABLE_CURSES=TRUE -DLLDB_DISABLE_LIBEDIT=TRUE -DCMAKE_CXX_FLAGS="-static-libstdc++ -static-libgcc" -DCMAKE_SYSTEM_NAME=Linux -DCMAKE_SYSTEM_PROCESSOR=aarch64 -DCMAKE_C_COMPILER=aarch64-linux-gnu-gcc -DCMAKE_CXX_COMPILER=aarch64-linux-gnu-g++ -DCMAKE_CROSSCOMPILING=TRUE -DLLVM_TARGET_ARCH=aarch64 -DLLVM_TABLEGEN=/workspace/build/llvm-host/bin/llvm-tblgen -DCLANG_TABLEGEN=/workspace/build/llvm-host/bin/clang-tblgen -DPYTHON_EXECUTABLE=/usr/bin/python3 -GNinja /workspace/source/llvm When I kick off a build, a few files get compiled, but then a nested build configuration is invoked: cd /workspace/build/lldb/NATIVE && /usr/bin/cmake -G Ninja -DCMAKE_MAKE_PROGRAM="/usr/bin/ninja" -DCMAKE_C_COMPILER=/usr/bin/aarch64-linux-gnu-gcc -DCMAKE_CXX_COMPILER=/usr/bin/aarch64-linux-gnu-g++ /workspace/source/llvm -DLLVM_TARGET_IS_CROSSCOMPILE_HOST=TRUE -DLLVM_TARGETS_TO_BUILD="X86;AArch64;ARM" -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="" -DLLVM_DEFAULT_TARGET_TRIPLE="x86_64-unknown-linux-gnu" -DLLVM_TARGET_ARCH="aarch64" -DLLVM_ENABLE_PROJECTS="clang;libcxx;lldb" -DLLVM_EXTERNAL_PROJECTS="" -DLLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN="OFF" -DCMAKE_BUILD_TYPE=Release -DLLVM_EXTERNAL_CLANG_SOURCE_DIR=/workspace/source/llvm/../clang ... which fails with this error: CMake Error at /usr/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find LibEdit (missing: libedit_LIBRARIES) (found version ".") Call Stack (most recent call first): /usr/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE) /workspace/source/lldb/cmake/modules/FindLibEdit.cmake:54 (find_package_handle_standard_args) /workspace/source/lldb/cmake/modules/LLDBConfig.cmake:104 (find_package) /workspace/source/lldb/CMakeLists.txt:21 (include) As far as I can tell, this happens because LLDB_DISABLE_LIBEDIT is not propagated to this nested build... but maybe I am missing some cmake flag? I'm building off of master, but the same thing happens with 9.0 release branch.
