Нет libclang.a после успешного создания для iOS?

Question

я извлек из официальных источников LLVM/Clang для 3.7 выпуска, сделали некоторые незначительные заплатки (NSGetEnviron()), сконфигурированные и построить для прошивкой с CMake:

cmake ../llvm_37_ios \ 
-DCMAKE_INSTALL_PREFIX=/Volumes/Transcend/dev/src/llvm_37_ios_armv7_installed \ 
-DLLVM_ENABLE_TERMINFO=OFF \ 
-DLLVM_ENABLE_THREADS=OFF \ 
-DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk \ 
-DCMAKE_C_FLAGS="-stdlib=libc++ -arch armv7 -mios-version-min=8.0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk" \ 
-DCMAKE_CXX_FLAGS="-stdlib=libc++ -arch armv7 -mios-version-min=8.0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk" \ 
-DCMAKE_CROSSCOMPILING=True \ 
-DLLVM_TABLEGEN=/Volumes/Transcend/dev/src/llvm_37_local_build/bin/llvm-tblgen \ 
-DCLANG_TABLEGEN=/Volumes/Transcend/dev/src/llvm_37_local_build/bin/clang-tblgen \ 
-DCMAKE_BUILD_TYPE=Release \ 
-DLLVM_TARGETS_TO_BUILD="ARM;X86" 

Однако я не нашел libclang.a, но нашли еще libclang*.a LIBS:

MBA-Anton:llvm_37_ios_armv7_build asmirnov$ find . -name "libclang.a" 
MBA-Anton:llvm_37_ios_armv7_build asmirnov$ find . -name "libclang*.a"

./lib/libclangTooling.a 
./lib/libclangFormat.a 
./lib/libclangStaticAnalyzerFrontend.a 
./lib/libclangStaticAnalyzerCore.a 
./lib/libclangStaticAnalyzerCheckers.a 

По какой-то причине общей библиотеки была создана, но статичным не было:

Я что-то пропустил или это ошибка конфигурации clang?

Answer 1

libclang по умолчанию используется как разделяемая библиотека, поскольку он упрощает потребление с других языков, таких как Python, с использованием FFI или подобных механизмов.

Для создания статического использования библиотеки LIBCLANG_BUILD_STATIC опцию CMake, определенный в clang/tools/libclang/CMakeLists.txt:

option(LIBCLANG_BUILD_STATIC 
    "Build libclang as a static library (in addition to a shared one)" OFF) 

Вы можете использовать его следующим образом:

cmake -DLIBCLANG_BUILD_STATIC=ON ...
