vxworks 和 vmware
Submitted by gougou on Tue, 2005-09-13 23:50因为VxSim模拟器支持的VxWorks功能有限,因此想装一个真正的VxWorks的运行环境,最开始想到的是在vmware上装一个,这样可以比较省事,但是花了一下午的时间,在MS—DOS虚机上装出来的VxWorks一启动就崩溃了,总是不行,后来在Google上查了一下,才发现Vmware不支持VxWorks,据说Wind River开发组的人内部是用修改过的Vmware和特殊的BSP以及驱动进行的开发,可惜我拿不到那样的版本,郁闷。看来只能老老实实的找台破电脑。

Antlr的贪婪模式语法
Submitted by gougou on Mon, 2005-08-29 09:43.-noscript-blocked { border: 1px solid red !important; background: white url("chrome://noscript/skin/icon32.png") no-repeat left top !important; opacity: 0.6 !important; }
下面的规则是非贪婪模式的语法,它会匹配{之后的任意字符而不会匹配}符号,
CURLY_BLOCK_SCARF
: '{' (.)* '}'
;
要想让Antlr能够匹配},我们需要将规则改为

Delphi调用VC生成用于C程序调用的DLL的注意事项
Submitted by gougou on Sat, 2005-08-27 16:45在VC中可以Export DLL函数供C程序调用
#define PARSERDLL_API __declspec(dllexport)
extern "C" {
PARSERDLL_API int GetSqlType(LPCTSTR szSql);
}
Delphi要想调用这样的针对C输出的函数,不能使用stdcall的调用规范,而应使用cdecl的调用规范
如何include预编译头文件到antlr生成的cpp中
Submitted by gougou on Sat, 2005-08-27 09:33在Antlr生成cpp文件时,我们可能希望添加预编译头文件StdAfx.h到cpp文件中,标准的Header开关只能把头文件include到生成的头文件,而不能是cpp文件。
要想添加头文件到cpp中,需要使用antlr cpp生成器特殊控制开关关键字pre_include_cpp,示意如下
header "pre_include_cpp" {
#include "StdAfx.h"
}
