Unknown argument -DDEMO=OFF

128ve900 commented 4 years ago

于老师，您好！我在编译动态库，执行 cmake --build . --config Release -DDEMO=OFF 时，报错 Unknown argument -DDEMO=OFF，请问是什么原因导致的呢？

Release前面漏了个等号？

于老师，我尝试Release前面加等号，仍然会报错 Unknown argument --config=Release Unknown argument -DDEMO=OFF

我是按照COMPILE.md 里面的指导逐步进行的：

执行 cmake .. -DCMAKE_PREFIX_INSTALL=install，输出日志是： `AVX512 = OFF AVX2 = ON NEON = OFF OpenMP = TRUE DEMO = OFF -- Configuring done -- Generating done CMake Warning: Manually-specified variables were not used by the project:

CMAKE_PREFIX_INSTALL

-- Build files have been written to: ***/build `

执行 cmake --build . --config Release -DDEMO=OFF，输出日志是： `Unknown argument -DDEMO=OFF Usage: cmake --build
[options] [-- [native-options]] Options:
= Project binary directory to be built. --target = Build instead of default targets. --config = For multi-configuration tools, choose . --clean-first = Build target 'clean' first, then build. (To clean only, use --target 'clean'.) --use-stderr = Ignored. Behavior is default in CMake >= 3.0. -- = Pass remaining options to the native tool.`

请问编译时对系统环境还有要求吗？我现在的系统是： `Distributor ID: Ubuntu

Description: Ubuntu 16.04.4 LTS

Release: 16.04

Codename: xenial

gcc version 5.4.0

cmake version 3.5.1

GNU Make 4.1 Built for x86_64-pc-linux-gnu`

期待您的回复，谢谢！

you can modify the CMakefile.txt by adding "set(DEMO OFF)",then cmake --build . --config Release

note: before the line "if (DEMO)"
