c++包管理工具conan使用

安裝

sudo pip install conan

參考官網的demo

git clone https://github.com/memsharded/example-poco-timer.git mytimer

命令

查看本地庫
conan search 
安裝庫
conan install zlib/1.2.8@lasote/stable
刪除庫
conan remove zlib/1.2.11@conan/stable

編寫conanfile.txt文件

[requires]
Poco/1.8.0.1@pocoproject/stable


[generators]
gcc

編寫main.cpp源文件

根據conanfile.txt文件生成conanbuildinfo.gcc conanbuildinfo.txt conaninfo.txt文件

conan install .

使用conanbuildinfo.gcc文件
