If I disable assembly in my cmake configure, I successfully compiled the 'libx265.a' library.But I found that the library without assembly optimization do encoding more slowly than expected.So I need the assembly version of 'libx265.a'!Then I installed Xcode4.6.3 which has llvm gcc 4.2 for iOS platform. I changed the 'ios.cmake' under 'build/arm-ios' to: set(CROSS_COMPILE_ARM 1) set(CMAKE_SYSTEM_NAME Darwin) set(CMAKE_SYSTEM_PROCESSOR armv7l)
set(CMAKE_C_COMPILER /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2) set(CMAKE _CXX_COMPILER /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-llvm-g++-4.2) set(CMAKE_FIND_ROOT_PATH /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk) # Skip the platform compiler checks for cross compiling set(CMAKE_C_COMPILER_WORKS TRUE) set(CMAKE_CXX_COMPILER_WORKS TRUE) and 'make-Makefiles.bash' under 'build/arm-ios' to: IOS_PLATFORM_SDK=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk IOS_FLAGS="-march=armv7 -mcpu=cortex-a8 -mfpu=neon -pthread -isysroot $IOS_PLATFORM_SDK -I$IOS_PLATFORM_SDK/usr/include -I$IOS_PLATFORM_SDK/usr/include/c++/4.2.1 -miphoneos-version-min=4.0 -Qunused-arguments -DHAVE_STRTOK_R" cmake -DCMAKE_TOOLCHAIN_FILE=ios.cmake -DCMAKE_C_FLAGS="$IOS_FLAGS" -DCMAKE_CXX_FLAGS="$IOS_FLAGS" -DIOS_PLATFORM_SDK="$IOS_PLATFORM_SDK" -G "Unix Makefiles" ../../source && cmake ../../source I can generate the 'Makefile' by run 'make-Makefiles.bash', but when I run 'make' to compile the codes, it reports many warnings like: In file included from /Applications/Xcode.app/Contents/Developer/Playforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/usr/include/semaphore.h:27, from .../source/common/threading.h:36, from .../source/common/frame.h:29, from .../source/common/analysis.cpp:27, /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/usr/include/sys/fcntl.h:493: warning: 'int flock(int, int)' hides constructor for 'struck flock' In file included from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneSDK6.1.sdk/usr/include/sys/proc.h:78, from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneSDK6.1.sdk/usr/include/sys/sysctl.h:84, from .../source/common/threading.h:43, from .../source/common/frame.h:29, from .../source/encoder/analysis.cpp:27: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneSDK6.1.sdk/usr/include/sys/event.h:317: warning:'int kevent(int, const kevent*, int, kevent*, int, const timesspec*)' hides the constructor for 'struct kevent' and finally stopped at the error: .../source/encoder/analysis.cpp: In member function 'void x265::Analysis::checkBidir2Nx2N(x265::Mode&, x265::Mode&, const x265::CUGeom&)': .../source/encoder/analysis.cpp:2190:error:invalid use of incomplete type 'class x265::MotionReference' .../source/encoder/reference.h:38:error:forward declaration of 'class x265::MotionReference' .../source/encoder/analysis.cpp:2190:error:invalid use of incomplete type 'class x265::MotionReference' .../source/encoder/reference.h:38:error:forward declaration of 'class x265::MotionReference' .../source/encoder/analysis.cpp:2190:error:invalid use of incomplete type 'class x265::MotionReference' .../source/encoder/reference.h:38:error:forward declaration of 'class x265::MotionReference' make[2]: *** [encoder/CMakeFiles/encoder.dir/analysis.cpp.o] Error 1 make[1]: *** [encoder/CMakeFiles/encoder.dir/all] Error 2 make: *** [all] Error 2 What's the problem?Did I configure settings right? 在 2016-06-24 22:44:51，"chen" <[email protected]> 写道： We use gcc assembly syntax, so you have to disable assembly in your cmake configure.
