<br>内容：我根据前辈的代码写了一个.dll 文件，但在调用时出了问题<BR>生成.dll的代码如下<BR>//sample.cpp<BR><BR>#include&lt;windows.h&gt;<BR><BR>WINAPI int Add(int a,int b)<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;return (a+b);<BR>}<BR><BR>//sample.def<BR>LIBRARY&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#34;sample&#34;<BR>DESCRIPTION&nbsp;&nbsp;'sample Windows Dynamic Link Library'<BR><BR>EXPORTS&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;; Explicit exports can go here<BR>&nbsp;&nbsp;&nbsp;&nbsp;Add<BR><BR><BR>//sample.h<BR><BR>WINAPI int Add(int a,int b);<BR><BR>编译之后，没有问题<BR>然后在call_sample工程中调用如下<BR><BR>//call_sample.cpp<BR>#include&lt;stdio.h&gt;<BR>#include&#34;d:\sample\sample.h&#34; //include sample.h进到call_sample工程<BR><BR>void main()<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;int c;<BR>&nbsp;&nbsp;&nbsp;&nbsp;c=Add(1,2);<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;printf(&#34;%d&#34;,c);<BR>}<BR>然后在.在工程中引入sample.lib: <BR>单击Project- &gt;Add to Project- &gt;files...<BR>&nbsp;&nbsp; 找到sample.lib文件,按OK<BR><BR>之后编译call_sample工程，有下面的错误，大虾请给诊断一下好吗？<BR>Compiling...<BR>call_sample.cpp<BR>d:\\sample\sample.h(1) : error C2144: syntax error : missing ';' before type 'int'<BR>d:\\sample\sample.h(1) : error C2501: 'WINAPI' : missing storage-class or type specifiers<BR>d:\sample\sample.h(1) : fatal error C1004: unexpected end of file found<BR>Error executing cl.exe.<BR><BR>call_sample.exe - 3 error(s), 0 warning(s)<BR><BR>谢谢！<BR><BR>
