copied!<p>Sure, you put this in one of your your header files, say preinit.h:</p> <pre><code>class Init { public: Init() { initialize(); } }; Init init; </code></pre> <p>and then, in <em>one</em> of your compilation units, put:</p> <pre><code>void initialize(void) { // weave your magic here. } #include "preinit.h" </code></pre> <p>I know that's a kludge but I'm not aware of <em>any</em> portable way to do pre-main initialization without using a class constructor executed at file scope.</p> <p>You should also be careful of including more than one of these initialization functions since I don't believe C++ dictates the order - it could be random.</p> <p>I'm not sure of this "sketch" of which you speak but would it be possible to transform the main compilation unit with a script before having it passed to the compiler, something like:</p> <pre><code>awk '{print;if (substr($0,0,11) == "int main (") {print "initialize();"};}' </code></pre> <p>You can see how this would affect your program because:</p> <pre><code>echo '#include <stdio.h> int main (void) { int x = 1; return 0; }' | awk '{ print; if (substr($0,0,11) == "int main (") { print " initialize();" } }' </code></pre> <p>generates the following with the <code>initialize()</code> call added:</p> <pre><code>#include <stdio.h> int main (void) { initialize(); int x = 1; return 0; } </code></pre> <p>It may be that you can't post-process the generated file in which case you should ignore that final option, but that's what I'd be looking at first.</p>
