Eu instalei duas versões do openCV: uma é openCV3 e outra uma openCV2.4 na minha máquina Ubuntu 16.04 e preciso de ambas. No entanto, agora sou incapaz de compilar o código C ++, que é destinado a openCV3. Eu recebo uma tonelada de erros de linker ao tentar compilar meu código que sempre compilou perfeitamente bem antes de instalar o openvc2.4
O tipo de erro que recebo:
