    <p>I'm trying to generate a dll file with swig from Visual Studio 2010, I created and compiled my wrapper.cpp code successfully and add every library dependencies to my project. Now when I try to build release version of my project with .dll target extension, I've got the following error:</p> <pre><code> Generating non-SAFESEH image. 1&gt;Ccrypto_wrap.obj : error LNK2019: unresolved external symbol "int __cdecl axtoi(char const *)" (?axtoi@@YAHPBD@Z) referenced in function __wrap_axtoi </code></pre> <p>That's wired, cause every other external symbols in wrapper.cpp have been resolved except </p> <p><code>axtoi</code>! I mean for example in my wrapper.cpp I have 2 references of <code>axtoi</code>:</p> <p>(1)</p> <pre><code>ZEND_NAMED_FUNCTION(_wrap_axtoi) { char *arg1 = (char *) 0 ; zval **args[1]; int result; SWIG_ResetError(); if(ZEND_NUM_ARGS() != 1 || zend_get_parameters_array_ex(1, args) != SUCCESS) { WRONG_PARAM_COUNT; } /*@SWIG:C:\Users\user\Desktop\Ccrypto\Lib\php\utils.i,62,CONVERT_STRING_IN@*/ if ((*args[0])-&gt;type==IS_NULL) { arg1 = (char *) 0; } else { convert_to_string_ex(args[0]); arg1 = (char *) Z_STRVAL_PP(args[0]); } /*@SWIG@*/; result = (int)axtoi((char const *)arg1); { ZVAL_LONG(return_value,result); } return; fail: SWIG_FAIL(); } </code></pre> <p>(2)</p> <blockquote> <p>SWIG_ZEND_NAMED_FE(axtoi,_wrap_axtoi,NULL)</p> </blockquote> <p>I created the shared object of my class successfully in Linux and I included it in my php codes and it works fine, so I tried to check <code>axtoi</code> in my shared object in Linux and I figured out an strange thing! when I grep <code>axtoi</code> inside my shared object I got:</p> <pre><code> U _Z5axtoiPKc 0006ccf1 T _wrap_axtoi </code></pre> <p>but for every other symbols for example <code>itoax</code> which its usage is the same as <code>axtoi</code> in the wrapper code I have:</p> <pre><code>00093660 T _Z5itoaxi 0006e19f T _wrap_itoax </code></pre> <p>I have several similar symbols which are used exactly the same as <code>axtoi</code> in my wrapper.cpp code as mentioned above, but I didn't get any unresolved external symbol errors. Any ideas?</p>

    1. CO`axtoi` sounds like a typo - are you sure you didn't type it instead of `atoi` somewhere?

    2. COYes, I didn't type anything, this function is one of the swig generated wrapper code functions, I mean xxx_wrap.cpp. when I try to build dll from this file and my class I get this error.

    3. COPosting an error message without any of the source or steps leading up to it isn't very useful.
