"dumpbin mydll.dll" will show section names and sizesI have 2 builds of PLplot.dll - both are the same size (3,327,028 bytes). I have named one of them PLplot_broken.dll, and the other PLplot_ok.dll. They can be obtained from:
http://www.sisyphusion.tk/junk/PLplot_broken.dll
and
http://www.sisyphusion.tk/junk/PLplot_ok.dll
Both were built using the same compiler, and against the same plplot static library.
Running 'dumpbin PLplot_broken.dll' and 'dumpbin PLplot_ok.dll produces identical results (except of course, for the file name that is reported):

If I use PLplot_ok.dll as the PLplot.dll I get:
C:\>pmver PDL::Graphics::PLplot
0.61
If I use PLplot_broken.dll as the PLplot.dll I get:
C:\>pmver PDL::Graphics::PLplot
Can't load 'C:/MinGW/perl589/site/lib/auto/PDL/Graphics/PLplot/PLplot.

+n32 application at C:/MinGW/perl589/lib/DynaLoader.pm line 226.

Any advice on how I might be able to come to an understanding of why one is ok, but the other not, would be most welcome.
Cheers,
Rob

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
