opencv checksum verification

Hi, I'm new to opencv and unfortunately I have failed at the first hurdle.

I downloaded the Windows 3.1.0 version with pre-built libraries from the link on the website which takes you to SourceForge. When I tried to extract the files I received an error. I had look online and it was suggested that the file had not downloaded correctly. So I tried downloading the file again, a few times infact, and now I have several files all of different sizes and with different md5 checksums.

So I have a couple of questions, are the checksums available so that I can tell if one of these files is the correct one? Secondly is it usual for this to happen or should I be concerned?

Many thanks.

As far as I know, the checksums are not available.

Here what I got (I downloaded twice the file with the same checksum):

  • md5: e86cfcb2e2fa4cc7232c5965ce98ed66 opencv-3.1.0.exe
  • sha256: 0cbb10fab967111b5b699a44cb224f5d729f8d852d2720cbd5cdb56d8770b7b3 opencv-3.1.0.exe

Thank you. That is the same as a couple of files I have downloaded.

The checksums are available on the Sourceforge page. Just click on the info/view details button right next to the download (i inside a dark circle)

the prebuilt binaries are for absolute noobs only.

in the long run, there will be bugs, bugfixes, additions.

get into the git(hub) flow instead.

Thank you, I'll certainly look into it.
