## 實驗環境

$ uname -a
 Linux  5.3.0-40-generic #32~18.04.1-Ubuntu 

$ gcc --version
gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0

## 作業要求

詳見 [https://hackmd.io/@sysprog/linux2020-lab0](lab0) 描述。

## 實驗記錄

一開始跟著步驟 `git clone` 下來後 make 出現

 CC    qtest.o
  CC    report.o
  CC    console.o
  CC    harness.o
  CC    queue.o
In file included from queue.c:5:0:
harness.h:66:0: error: "strdup" redefined [-Werror]
 #define strdup test_strdup
 ^
In file included from /usr/include/string.h:630:0,
                 from queue.c:3:
/usr/include/x86_64-linux-gnu/bits/string2.h:1291:0: note: this is the location of the previous definition
 #   define strdup(s) __strdup (s)
 ^
cc1: all warnings being treated as errors
Makefile:37: recipe for target 'queue.o' failed
make: *** [queue.o] Error 1

:::warning
近期 [lab0-c](https://github.com/sysprog21/lab0-c) 有些修正，請嘗試更新，方法為:
a. 切換到 lab0-c 的 workspace
b 執行 `$ git remote add upstream https://github.com/sysprog21/lab0-c`
c. 執行 `$ git fetch upstream`
d. 執行 `$ git rebase upstream/master`

最後一步可能會遇到衝突，可參見 [另一種合併方式（使用 rebase](https://gitbook.tw/chapters/branch/merge-with-rebase.html)。
