    copied!<p>The software I am talking of contains 5 files and compiles "perfectly fine" on <code>openSUSE 11.3</code> with <code>gcc-4.5.1</code>:</p> <p>The same software shows the following error on <code>Windows XP</code> with <code>Mingw (gcc-4.6.3)</code>.</p> <p><strong>UPDATE</strong></p> <p>The problem is discovered.</p> <p>The problem is w.r.t the R's function <code>parseEval</code>. There are two similar functions: <code>parseEval</code> and <code>parseEvalQ</code>. The former returns a value, and the other returns void.</p> <p>I have used <code>parseEval</code> in a C++ plus Qt project, and it works very fine on Linux, and throws the above shown error on Windows.</p> <p><strong>Here is the reproducible example:</strong></p> <p>demo.cpp</p> <pre><code>#include &lt;iostream&gt; #include &lt;RInside.h&gt; #include &lt;Rcpp.h&gt; RInside R (0, NULL); RInside &amp; qtToR (R); int main () { int numberOne = 1; int numberTwo = 2; qtToR ["numberOne"] = numberOne; qtToR ["numberTwo"] = numberTwo; R.parseEvalQ ("sum = numberOne + numberTwo;"); int returnValue = R.parseEval ("sum"); std :: cout &lt;&lt; "\n" &lt;&lt; returnValue &lt;&lt; "\n"; } </code></pre> <p>Corresponding .pro file:</p> <pre><code>TEMPLATE = app TARGET = DEPENDPATH += .
