本文介绍了在VC中针对无LIB时的DLL隐式链接,制作可供VC++使用的LIB函数符号输入库。具体步骤如下：
EXAMPLE：
DUMPBIN VideoDeCoder.dll /EXPROTS /OUT:VideoDeCoder.def
EXAMPLE：VideoDeCoder.DEF 文件内容如下Dump of file VideoDeCoder.dll
File Type: DLL
Section contains the following exports for VideoDeCoder.dll

Summary
2000 .data
1000 .rdata
1000 .reloc
15000 .text
按照以下方法整理:
1)添加LIB说明 LIBRARY "VideoDeCoder" ;"xx"为DLL名称
DESCRIPTION "VideoDeCoder library"
2)去掉导出函数说明端以外的内容,在LIB说明下添加 "EXPROTS" 说明导出函数 LIBRARY "VideoDeCoder"
DESCRIPTION "VideoDeCoder library"
EXPORTS
ordinal hint RVA name
1 0 00010F60 _TM_ClearDecoderBuff@4
2 1 00010E80 _TM_CloseDecoder@4
3 2 00010F00 _TM_DecodePicture@
4 3 00010ED0 _TM_DecodePictureH
5 4 00010FD0 _TM_GetFileEnd@4
6 5 00011030 _TM_GetUValue@4
7 6 00011060 _TM_GetVValue@4
8 7 00011000 _TM_GetYValue@4
9 8 00010E10 _TM_OpenDecoder@8
10 9 00010F30 _TM_ReturnType@4
11 A 00010F90 _TM_SetFileEnd@8
3)将所有的函数放至行首,去掉 "hint" 和 "RVA" 数据,留下函数的序号 "ordinal" ,在序号前加上 "@" 符号 形成 "_导出函数名@参数字节和 @序号" 此种格式(__stdcall 方式调用导出的函数符号是 "函数名称@参数字节和"). 最后形成.DEF文件如下: LIBRARY "VideoDeCoder"
DESCRIPTION "VideoDeCoder library"
EXPORTS
TM_ClearDecoderBuff@4 @1
TM_CloseDecoder@4 @2
TM_DecodePicture@4 @3
TM_DecodePictureHeader@4 @4
TM_GetFileEnd@4 @5
TM_GetUValue@4 @6
TM_GetVValue@4 @7
TM_GetYValue@4 @8
TM_OpenDecoder@8 @9
TM_ReturnType@4 @10
TM_SetFileEnd@8 @11
EXAMPLE:LIB /DEF:VideoDeCoder.def /MACHINE:IX86
