刚才下载了，可是 ./configure时出了个问题，我对这些不怎么懂，将过程贴出来吧：

1. 
   
2. # ./configure
   
3. checking for a BSD-compatible install... /usr/bin/install -c
   
4. checking whether build environment is sane... yes
   
5. checking whether make sets $(MAKE)... yes
   
6. checking for working aclocal-1.4... missing
   
7. checking for working autoconf... missing
   
8. checking for working automake-1.4... missing
   
9. checking for working autoheader... missing
   
10. checking for working makeinfo... missing
    
11. checking for gcc... gcc
    
12. checking for C compiler default output file name... configure: error: C compiler cannot create executables
    
13. See `config.log' for more details.

你的系统安装了c编译器和glibc了吗?

Post by sunmoon1997
如果是我会这样写。。
#define  xfree (p) do { \
       free (p); \
       p = NULL; \
} while (0)

用预处理不方便gdb调试,对可读性也没有好处. Gnu代码规范有相似尽管不同的建议.

nait

为什么#define时要用do....while(0)呢?
我以前也看到过好多这样的用法
一直百思不得其解

望赐教

就是为了看起来爽一点。

我的理解是while(0)后有个";".  
如果有这样一段不规范的代码:

1. 
   
2. #define T if () { }
   
3. if() T;
   
4. else {};
   

复制代码

预处理后的结果::

1. 
   
2. if()
   
3.   if(){};
   
4.   else{};

大家看看有什么问题.

phc-1.1的代码问题尽管提,希望今天能见到更多的问题或者bug报告,因为可能又要忙一段时间了...

btw,内存管理原来是想重新写的,后来没时间就仓促发布了,可能是匆忙删除时搞错了. 对于phc的内存管理大家有没有什么建议?  用链表动态管理? 或者推荐我一些在线文档?   谢谢!

干嘛要把那些全局的变量声明放到头文件里去啊
