cmake的问题

lcl1026504480

我的CMakeLists.txt:

1. cmake_minimum_required(VERSION 3.4)
   
2. set(CMAKE_C_COMPILER "gcc")
   
3. set(CMAKE_CXX_COMPILER "g++")
   
4. set(CMAKE_MAKE_PROGRAM  "mingw32-make")
   
5. project(fraction)
   
6. add_executable(fraction fraction2,cxx)

复制代码

结果为什么是这样：
S C:\Users\lenovouser\Desktop\cpp\Lesson17\fraction> cmake . -G  "MinGW Makefiles"

我原来用的最新版的cmake也报错，我以为是版本太新了

lcl1026504480

cmake_minimum_required(VERSION 3.4)
set(CMAKE_C_COMPILER "gcc")
set(CMAKE_CXX_COMPILER "g++")
set(CMAKE_MAKE_PROGRAM  "mingw32-make")
project(fraction)
add_executable(fraction fraction2.cpp)

这个已经解决了，是路径的问题
