testcpplib's Introduction

linux下将c++代码打包成静态库和动态库并使用的方法。

# 1. 静态库
脚本为:test_static_lib.sh

生成静态库:
[hwang@MJ_Dev:~/test/TestLib]$ ls
test.cpp  wind.cpp  wind.h
[hwang@MJ_Dev:~/test/TestLib]$ g++ -c wind.cpp -o wind.o
[hwang@MJ_Dev:~/test/TestLib]$ ar -crv libwind.a wind.o
a - wind.o
[hwang@MJ_Dev:~/test/TestLib]$ ls
libwind.a  test.cpp  wind.cpp  wind.h  wind.o

使用静态库:
[hwang@MJ_Dev:~/test/TestLib]$ ls
libwind.a  test.cpp  wind.cpp  wind.h  wind.o
[hwang@MJ_Dev:~/test/TestLib]$ g++ test.cpp -o test -static -L. -lwind
[hwang@MJ_Dev:~/test/TestLib]$ ./test 
StaticFunc test!
MemberFunc test!
GlobalFunc test!

# 2. 动态库
脚本为:test_dynamic_lib.sh

生成动态库:
[hwang@MJ_Dev:~/test/TestLib]$ ls
test.cpp  wind.cpp  wind.h
[hwang@MJ_Dev:~/test/TestLib]$ g++ -shared -fpic -o libwind.so wind.cpp
[hwang@MJ_Dev:~/test/TestLib]$ ls
libwind.so  test.cpp  wind.cpp  wind.h

使用动态库:
[hwang@MJ_Dev:~/test/TestLib]$ ls
libwind.so  test.cpp  wind.cpp  wind.h
[hwang@MJ_Dev:~/test/TestLib]$ g++ test.cpp -o test -L. -lwind
[hwang@MJ_Dev:~/test/TestLib]$ export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH
[hwang@MJ_Dev:~/test/TestLib]$ ./test 
StaticFunc test!
MemberFunc test!
GlobalFunc test!
