Android.mk与Linux Makefile研究心得

一、Android NDK中列出的部分库文件：
 
 
 
 |-- crtbegin_dynamic.o
 
 |-- crtbegin_static.o
 
 |-- crtend_android.o 
 
 
 |-- libc.a
 
 
 
 |-- libc.so
 
 
 
 |-- libdl.so
 
 
 
 |-- liblog.so
 
 
 
 |-- libm.a
 
 
 
 |-- libm.so
 
 
 
 |-- libstdc++.a
 
 
 
 |-- libstdc++.so
 
 
 
 |-- libthread_db.a
 
 
 
 |-- libthread_db.so
 
 
 
 `-- libz.so 
 
 
  
 
 
 






二、libstdc++.a编译过程分析









$ ar x libstdc++.a
 
 libstdc++.a 









|-- new.o
 
 |-- one_time_construction.o
 
 |-- pure_virtual.o
 
 `-- typeinfo.o
