"dumpbin mydll.dll" will show section names and sizes
I 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:
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):
Microsoft (R) COFF/PE Dumper Version 7.00.9466

Dump of file PLplot_ok.dll
File Type: DLL
If I use PLplot_ok.dll as the PLplot.dll I get:
If I use PLplot_broken.dll as the PLplot.dll I get:
Can't load 'C:/MinGW/perl589/site/lib/auto/PDL/Graphics/PLplot/PLplot.

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.
