"In-depth understanding of computer systems" on Csapp.h and CSAPP.C compilation issues

The compile steps are as follows:

1. My current working directory is/home/sxh2/clinux, the directory has 3 files inet_aton.c csapp.h csapp.c.

2. Compile the csapp.c file, the command is Gcc-c csapp.c, generate the target file CSAPP.O.

3. Compile the inet_aton.c file, the command is Gcc-c INET_ATON.C, generate the target file INET_ATON.O.

4. Link the target file csapp.o, INET_ATON.O (due to the csapp.c file in the part of the thread, GCC compile must take-lpthread, otherwise error), command for Gcc-o main CSAPP.O inet_ Aton.o-lpthread, generate the executable file main, run it.

Before solving this problem, I tried to try the online approach, not very good, and still have errors. Here, I should be able to run successfully, but it is not recommended.

The steps are as follows:

1. Put the csapp.h csapp.c file in/usr/include (the way you look at others is put under/usr/lib, try not to)

2. In Csapp.h, add the last line #end if before :

< csapp.c >

In fact, it is not necessary to write Csapp.c file, directly copy the contents of the Csapp.c file to csapp.h the last line of the #end if before. However, this does not comply with the principle of interface and implementation separation.

The 3.csapp.c file has a section on the thread, GCC compilation must take-lpthread, otherwise it will be wrong.

4. Add # include <csapp.h> to the header of the file to be compiled

5 Specific instructions are as follows: GCC Inet_aton.c-lpthread.
