Google (http://groups.google.com/group/microsoft.public.win32.programmer.kernel/msg/4e96409329944018?dmode=source) says you have a non-relocatable DLL. I think you messed up a different compiler flag when you removed -s, or there is a bug in your Mingw. Look for a PE .reloc section (looking at mingw produced dlls, they all have .reloc sections), or for a by the book answer 100% accurate answer, look in the Data Directory, then at IMAGE_DIRECTORY_ENTRY_BASERELOC entry ("Relocation Table") and make the RVA and size aren't 0. I use StudPE. There are other tools out there ("dumpbin mydll.dll" will show section names and sizes, I also know of PE Explorer (shareware)). Try running dependency walker on a dll that was compiled with "-s" and the makefile unchanged.	[reply]

I think you messed up a different compiler flag when you removed -s I did the first time and it wouldn't compile, but not this time, I'm sure :) or there is a bug in your Mingw This could very well be, but the message is the same with both my perls and compilers -- one is everything compiled with `gcc version 4.6.3 (gcc-4.6.3 release with patches [build 20121012 by perlmingw.sf.net])` the other is a mix of gcc versions ( perl compiled with 4.5.2, maybe (probably not) some modules with 4.6 something, xml2 with 4.7.0 ), but the errors messages are identical I've also got filealyzer and gcc comes with dumpbin-alike objdump, and there is a reloc section listed with a "RVA" entry size aren't 0 `$ ack -in size 2 \|head SizeOfCode 0010f000 SizeOfInitializedData 00288800 SizeOfUninitializedData 00001a00 SizeOfImage 005d0000 SizeOfHeaders 00000600 SizeOfStackReserve 00200000 SizeOfStackCommit 00001000 SizeOfHeapReserve 00100000 SizeOfHeapCommit 00001000 NumberOfRvaAndSizes 00000010 $ ack -n RVA 2 [ 0] +base[ 1] 2b500 Export RVA [ 1] +base[ 2] 2b500 Export RVA` [download] My search for that error message yielded http://stackoverflow.com/questions/2622607/windows-loader-problem-turn-on-verbose-mode which I don't understand :)	[reply] [d/l] [select]

Skip Dynaloader, do it the simpler way. `use Win32; my $ret = Win32::LoadLibrary('C:\Perl\site\lib\auto\blah\foo.dll'); print "ret=$ret glr=".Win32::GetLastError()."\n";` [download] What happens with Dependency Walker and without Dependency Walker when running the above script? 0xc000007b is STATUS_INVALID_IMAGE_FORMAT, which maps to ERROR_BAD_EXE_FORMAT which is "%1 is not a valid Win32 application.".

"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: `http://www.sisyphusion.tk/junk/PLplot_broken.dll and http://www.sisyphusion.tk/junk/PLplot_ok.dll` [download] 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 Copyright (C) Microsoft Corporation. All rights reserved.

sections /29, /59, and .reloc are different sizes. .text is identical size. The instructions in .text I am pretty sure (didn't look too deeply, using my tools) are identical except for the effects of relocation. The 2 DLLs have different base addresses, and both are i386 and have identical PE headers except for the relocation. Where can I get a copy of libgcc_s_dw2-1.dll? Strawberry perl 5.8.9.5 doesn't have one. Both files gave me this warning when I used PE Explorer on them. " Warning! Section </4> (3) extends beyond the raw file offset of section <.bss> (4)."
