我试图从PSDK发送的IDL文件中生成类型库，但在midl会话成功完成（ERRORLEVEL 0）时，没有生成.tlb文件。目前我不知道有什么不对。请指教。
这是一个详细的输出形式midl会话：

使用的零件和工具：
emptyvc.idl MIDL版本7.00.0555 CL版本14.00.50727.42 注意：我认为这不是环境问题，因为我尝试的第一件事是编译其他.idl文件，我得到了预期的结果.tbl，在转弯时由TLIBIMP处理没有任何麻烦。
这是CL输出（由MIDL完全静音运行）：
dlldata.c
dlldata.c(24) : error C2061: syntax error : identifier 'PROXYFILE_LIST_START'
dlldata.c(24) : error C2059: syntax error : ';'
dlldata.c(31) : error C2146: syntax error : missing ';' before identifier 'DLLDATA_ROUTINES'
dlldata.c(38) : fatal error C1004: unexpected end-of-file found
答案 0 :(得分：1)
MIDL有一种令人讨厌的习惯，即如果没有任何东西可以产生，就不会产生输出。您是否确认emptyvc.idl文件中包含可以在类型库（类，接口，库指令等）中表示的类型？
