hello, i m using open cv 2.4.13 and codeblocks-16.01mingw-setup, i cant compile the simple program, please help me , tanks [closed]

edit

for various reasons, please remove the useless screenshot, and give us a text version of

• your code
• how you link it
• the errors you get !

using mingw is always a bit unfortunate. did you build the opencv libs for mingw before ? (you cannot use the prebuild VS libs)

i get error : undefined reference to `cv::imread(std::string const&, int)'

yes, let's find out why.

(and again, please remove the screenshot.)

well i did it. please, edit again, and give us any details you have.

did you build the opencv libs before or not ?

ok, i have a simple code, load an image (using imread), but i get error : undefined reference to `cv::imread(std::string const&, int)'

please answer my question

no, i did not build the opencv libs before

how to build the opencv libs?

so, you cannot use the prebuild libs, they're for another toolchain (VS).

if you're a n00b, your best option is to discard the whole codeblocks/mingw idea entirely, and get VS community edition instead (huge download, though)

if you insist tio use mingw, you'll have to:

• get mingw64 (miingw32 won't work !)
• get cmake
• build the opencv libs using that.
