i have tried to codeblocks exact same error

the developper has release new version 2.0.7 fixing issue. have done have aruco:

• download .zip on sourceforge

• unzip it

• create build folder in aruco-2.0.7

• open cmake-gui configure , generate

• go build folder

• open cmd window there

• type mingw32-make

the library should have compiled properly. if omp.h missing compiler, find source code on internet , add mingw in mingw\include.
should ready go. don't forget add aruco path & reboot. if using ide, have add library since external library issue. finally, might have issues regarding c++11. working on it. if knows how allow on mingw (i haven't find understandable explanation far)
