<div class="markdown_content"><p>When compiling libiptcdata on Windows, using MSYS+MinGW, I get 2 undefined references because of link() and chown() in main.c (respectively lines 835 and 850)</p> <p>Instead of link(), we can use CreateHardLink() which is more or less the same thing, with 2 limitations : it works only with Windows 2000 or above, and only with NTFS. Instead of</p> <p>if (link (filename, bakfile) &lt; 0)</p> <p>we can do</p> <p>if (CreateHardLink(bakfile, filename, NULL))</p> <p>guarded by _WIN32, or alternatively:</p> <p>#ifdef _WIN32<br /> static int link(const char *oldpath, const char *newpath)<br /> {<br /> if (CreateHardLink(newpath, oldpath, NULL))<br /> return -1;<br /> else<br /> return 0;<br /> }<br /> #endif</p> <p>so that the code is not modified, and windows.h should be included like that:</p> <p>#ifdef _WIN32<br /> #define _WIN32_WINNT 0x0500<br /> #define WIN32_LEAN_AND_MEAN<br /> #include &lt;windows.h&gt;<br /> #undef WIN32_LEAN_AND_MEAN<br /> #endif</p> <p>about chown, maybe the following link can be of some help :</p> <p><a href="http://wwwthep.physik.uni-mainz.de/~frink/chown/readme.html#concept" rel="nofollow">http://wwwthep.physik.uni-mainz.de/~frink/chown/readme.html#concept</a></p></div>
