### 手动编译链接

1. 预编译

```shell
gcc -E helloworld.c -o helloworld.i
```

2. 编译汇编指令

```shell
gcc -S helloworld.i -o helloworld.s
```

3. 生成目标文件

```shell
gcc -c helloworld.s -o helloworld.o
```

4. 自动链接库得到可执行文件

```shell
gcc -v helloworld.o -o helloworld
```

#### 编译静态链接库

```shell
gcc -c helloworld.c
ar rcs libhellowrold.a helloworld.o
ar t libhellowrold.a
gcc main.c libhellowrold.a -o helloworld
```

#### 编译动态链接库

```shell
# linux
gcc -shared -fPIC helloworld.c -o libhellowrold.dll
#widows
gcc -shared -fPIC -Wl,--out-implib,libhellowrold.lib helloworld.c -o libhellowrold.dll

objdump -t libhellowrold.dll
gcc main.c -L. -lhelloworld -o helloworld # 加载链接库默认是运行路径，如果没有则找PATH路径
```

### CMAKE编译

#### 动态链接库子模块

```cmake
if (WIN32)
    set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS 1)
endif ()

add_library(helloworld SHARED helloworld.c)
install(TARGETS helloworld
        RUNTIME DESTINATION bin
        LIBRARY DESTINATION lib
        ARCHIVE DESTINATION lib/static
        )
```

#### 静态链接库子模块

```cmake
add_library(helloworld STATIC helloworld.c)
```

#### 主模块配置

```cmake
set(CMAKE_INSTALL_PREFIX install)

if (APPLE)
    set(CMAKE_INSTALL_RPATH @loader_path/../lib)
elseif (UNIX)
    set(CMAKE_INSTALL_RPATH \$ORIGIN/../lib)
endif ()

add_subdirectory(helloworld)
target_link_libraries(main helloworld)
install(TARGETS main RUNTIME DESTINATION bin)
```

#### 引入Conan生成配置

```cmake
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
```
