私はこの問題を解決するために、私は間違っているつもりどこかさっぱりだが。誰でも助けてくれますか？
わかりませんが、 '$ {ProjectDir}/libjpeg.a'と一緒に' -ljpeg'フラグが必要ないことを思い出してください。 （しかし、わかりませんが、私はopencvをコンパイルしてからしばらくしています） –
あなたのコメントをありがとう。それは、私がビルドに間違ったことをしていて、回避策を見つけることを許してくれたという感じを私に与えました。 –
あなたはそれが正常に働いているのを見てうれしいです、そして、あなた自身の質問に答える良い仕事は、将来のユーザーが利益を得ることができるように！ :) –
