Libwebsockets庫的構建

Libwebsockets庫的構建

• 若未安裝CMake，則先進行CMake的安裝

安裝CMake安裝如下步驟進行：

1. wget https://cmake.org/files/v3.3/cmake-3.3.2.tar.gz 

 

1. # tar xzvf cmake-3.3.2.tar.gz
2. # ./bootstrap
3. # make
4. # make install

 

#mkdir build

#cd build

#cmake ..

#make

#提供libcrypto.so  libssl.so

編譯成功後：將build下的share/libwebsockets-test-server文件夾拷貝到/usr/local/share/路徑下，然後執行服務器：./bin/libwebsockets-test-server

• 使用交叉編譯器arm-linux-gnueabihf-gcc編譯libsockets庫：

cmake .. \

-DCMAKE_INSTALL_PREFIX=/usr/local/libwebsockets-master/myout \

-DCMAKE_SYSTEM_NAME=Linux -DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc \

-DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++ \

-DLWS_OPENSSL_LIBRARIES="/usr/local/gcc-linaro-arm-linux-gnueabihf-4.9-zmm720-64/arm-linux-gnueabihf/lib/libssl.so;/usr/local/gcc-linaro-arm-linux-gnueabihf-4.9-zmm720-64/arm-linux-gnueabihf/lib/libcrypto.so"
