Issues with building

[codetheweb]

At first, I had quite a few issues when I tried to build this on a Raspberry Pi. I built OpenCV from scratch, and now I'm getting different errors:

'map' was not declared in this scope (depth.cpp:161)
expected primary-expression before ',' token (depth.cpp:161)
expected primary-expression before '*' token (depth.cpp:161)
expected primary-expression before '>' token (depth.cpp:161)
'threads' was not declared in this scope (depth.cpp:161)
'Display_Game_Piece' was not declared in this scope (depth.cpp:187)

It seems a little strange that all the errors come from depth.cpp, and most of them are on line 161. Any ideas on what's going wrong?

Hmm. For reference, what operating system/version are you using? Try to add an

include

at the beginning of the depth.cpp file. Thanks for your interest in our vision software! Sent from my iPhone

I'm running Raspbian 3.18.7. Including map got rid of those errors, but introduced new ones:

robot.o: undefined reference to symbol '_ZN2cv7imwriteERKNS_6StringERKNS_11_InputArrayERKSt6vectorliSaliEE'
error adding symbols: DSO missing from command line (libopencv_imgcodecs.so.3.0)
collect2: error: ld returned 1 exit status

And none of the errors give a line number. Do you think these errors are coming from trying to compile the code on a ARM processor? What processor did you compile it on? Thanks.

The program runs on an ODroid XU, which has the Samsung Exynos5 Octa ARM Cortex.

Based off "libopencv_imgcodecs.so.3.0" I suspect your installation of opencv messed up somewhere.

Okay... I'm using the latest dev beta build, 3.x. Maybe it's a compatibility issue. What version of OpenCV do you have, and did you install it through a package manager or compile yourselves?

[cmastudios]

I see. We have been using OpenCV 2.4.10 for the project. It works fine when installed through APT however the Xtion support is missing. I compiled it from source on the ODROID.

Ugh. Last time it took forever to compile 3.0 on the Pi, I'll probably have to compile 2.4 overnight. I'll tell you the results tomorrow.

It built with 2.4.10! Moral of the story: always use the same version of a library as the authors. Thanks for your help!
