PaddleSpeech/demos/TTSArmLinux 编译提示Could NOT find OpenMP_C

[newuser123k789]

CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)
Call Stack (most recent call first):
/usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE)
/usr/share/cmake-3.16/Modules/FindOpenMP.cmake:511 (find_package_handle_standard_args)
CMakeLists.txt:51 (find_package)

请问这个是什么原因造成，一般怎么解决?这个openMP需要自己安装还是系统自带的

这个问题解决了，可以编译成功了。

我理解有问题，这个demo应该是跑在有Ubuntu的arm板子上的，若要在电脑上虚拟机中编译，需要交叉编译，需要修改cmake的配置。cmake -DCMAKE_TOOLCHAIN_FILE=cfg_file_path cmake 会执行 CMAKE_TOOLCHAIN_FILE
变量所指定的源文件，对交叉编译进行设置。
可能需要重新编译paddle-lite,里面也同样需要修改cmake的配置。

需要修改的位置：-DCMAKE_TOOLCHAIN_FILE=/home/paddle/cross-compile/arm-linux-setup.cmake
PaddleSpeech/demos/TTSArmLinux：build.sh config.sh
src/CMakeLists.txt（可能需要增加set(TOOLCHAIN_DIR /opt/atk-dlrv1126-toolchain)
set(CMAKE_CXX_COMPILER ${TOOLCHAIN_DIR}/usr/bin/arm-linux-gnueabihf-g++)
set(CMAKE_C_COMPILER ${TOOLCHAIN_DIR}/usr/bin/arm-linux-gnueabihf-gcc)
set(SYSROOT ${TOOLCHAIN_DIR}/arm-buildroot-linux-gnueabihf/sysroot/usr/include)
set(CMAKE_SYSROOT ${TOOLCHAIN_DIR}/arm-buildroot-linux-gnueabihf/sysroot)

target_include_directories(paddlespeech_tts_demo PRIVATE /home/paddle/PaddleSpeech/demos/TTSArmLinux/src/TTSCppFrontend/third-party/build/include)
target_link_directories(paddlespeech_tts_demo PRIVATE /home/paddle/PaddleSpeech/demos/TTSArmLinux/src/TTSCppFrontend/third-party/build/lib)

target_include_directories(paddlespeech_tts_demo PRIVATE /home/paddle/Paddle-Lite/build.lite.linux.armv7hf.gcc/inference_lite_lib.armlinux.armv7hf/cxx/include)
target_link_directories(paddlespeech_tts_demo PRIVATE /home/paddle/Paddle-Lite/build.lite.linux.armv7hf.gcc/inference_lite_lib.armlinux.armv7hf/cxx/lib)
）

PaddleSpeech/demos/TTSCppFrontend： build.sh build-depends.sh third-party/CMakeLists.txt(可能需要增加-DGFLAGS_NAMESPACE=gflags）

Paddle-Lite/lite/tools :build_linux.sh

cmake的交叉旁边有配置文件：
arm-linux-setup.cmake：
set(CMAKE_SYSTEM_NAME Linux) #设置目标系统名字
set(CMAKE_SYSTEM_PROCESSOR arm) #设置目标处理器架构
指定编译器的sysroot路径

set(TOOLCHAIN_DIR /opt/atk-dlrv1126-toolchain/bin)
set(CMAKE_SYSROOT /opt/atk-dlrv1126-toolchain/arm-buildroot-linux-gnueabihf/sysroot)
指定交叉编译器arm-linux-gcc

set(CMAKE_C_COMPILER ${TOOLCHAIN_DIR}/arm-linux-gnueabihf-gcc)
set(CMAKE_CXX_COMPILER ${TOOLCHAIN_DIR}/arm-linux-gnueabihf-g++)

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
