三、编译报错问题解决
3.1 编译报Curses问题处理
【问题描述】
执行命令python3 ./toolchain/llvm-project/llvm-build/build.py
报错如下:
CMake Error at /home/wen_fei/OpenHarmony/llvm-toolchains/prebuilts/cmake/linux-x86/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message): Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH) Call Stack (most recent call first): /home/wen_fei/OpenHarmony/llvm-toolchains/prebuilts/cmake/linux-x86/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE) /home/wen_fei/OpenHarmony/llvm-toolchains/prebuilts/cmake/linux-x86/share/cmake-3.16/Modules/FindCurses.cmake:258 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) src/CMakeLists.txt:92 (find_package) -- Configuring incomplete, errors occurred!
【问题分析】
出现该错误的是因为在系统中找不到libncurses.so
库的原因
【问题处理】文章来源:https://www.toymoban.com/news/detail-824423.html
-
安装如下软件
sudo apt-get install liblua5.1-dev sudo apt install libncurses5
-
进入
/usr/lib
目录下执行find ./ -name libncurses.so*
,发现这些库都在x86_64-linux-gnu
目录下# find . -name libncurses.so* ./x86_64-linux-gnu/libncurses.so.6 ./x86_64-linux-gnu/libncurses.so ./x86_64-linux-gnu/libncurses.so.5.9 ./x86_64-linux-gnu/libncurses.so.5 ./x86_64-linux-gnu/libncurses.so.6.2
-
添加软链接
sudo su cd /usr/lib ln -s ./x86_64-linux-gnu/libncurses.so libncurses.so
-
重新编译即可

【问题分析】
出现该错误是需要安装binutils-dev
【问题处理】
-
执行如下命令
sudo apt-get -f -y install binutils-dev
-
使用以下命令查找
plugin-api.h
