Nginx的configure, make以及install

./configure --prefix=/xx --with-debug --with-cc-opt=‘-g -O0 -finstrument-functions‘
make
make install

将etrace代码加入Ngnix

将ptrace.c拷贝至Nginx源码core目录下。修改objs/Makefile

objs/nginx: objs/src/core/nginx.o             objs/src/core/ptrace.o 
$(LINK) -o objs/nginx objs/src/core/nginx.o objs/src/core/ptrace.o  
objs/src/core/nginx.o:  $(CORE_DEPS)    src/core/nginx.c
   $(CC) -c $(CFLAGS) $(CORE_INCS)       -o objs/src/core/nginx.o       src/core/nginx.c

objs/src/core/ptrace.o: $(CORE_DEPS)    src/core/ptrace.c
   $(CC) -c $(CFLAGS) $(CORE_INCS)       -o objs/src/core/ptrace.o       src/core/ptrace.c
