c# - Why am I getting badimagexception? -


i have code sample that's supposed detect canon 550d digital camera can control camera pc. downloaded source files here:

http://www.codeproject.com/articles/17344/a-wrapper-for-the-canon-cdsdk-and-prsdk-for-remote?fid=379739&df=90&mpp=25&noise=3&prof=false&sort=position&view=quick&spc=relaxed&fr=1#xx0xx

i created new project in visual studio 2012 pro; pc running windows 8 64bit. added .cs files , copied dll files downloaded canon website after registering.

the first time ran program , clicked on connect button, got exception dll missing. since there no way add dlls referenced, copied them debug directory.

the missing dll prsdk.dll, found , downloaded dll, , copied it.

now when click on connect button, different exception:

badimageformatexception: attempt made load program incorrect format. (exception hresult: 0x8007000b)

the exception in file camera.cs, on line:

err = prapi.pr_startsdk();

i googled exception , found people have changed project platform , target x86, tried - tried changing x86, x64, anycpu, everything, didn't help.

maybe prsdk.dll file old , not useable in windows 8?

this link project/solution in skydrive, if can please download , try run on machine , maybe find solution?

the project called: canon_camera_control

ok, downloaded project , found problem.

your dll files wrong!

they not dll actually, html files .dll extension. apparently tried download them webpage didn't succeed.

try redownloading or obtain sdk official (canon) sources.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
