今天我在运行一个代码时出现了段错误。
（1）用gdb查看core文件信息

（2）使用gdb设置断点进行单步调试
未进入main函数就出现段错误！
（3）检查Makefile内容
*******************************************************************************************
OBJC=test-client.cpp
TARC=test-client
CXX=g++
CXXFLAGS=-shared -fPIC -Wall -g -I../hrd/ -L../lib/ -lprotocol
all:$(TARC)
$(TARC):$(OBJC)
$(CXX) $(OBJC) $(CXXFLAGS) -lclient -o $(TARC)
install:
cp $(TARC) ../bin/
clean:
rm -f $(TARC)
*******************************************************************************************
（4）结论
原来是编译参数搞错，将生成共享库的编译参数错误地用于生成可执行文件！
