2つのOpenCVバージョン：互いに分離する必要があるにもかかわらず、1つを更新すると他のバージョンがクラッシュします。

私のLinuxディストリビューション（Antergos）は、約1週間前にリポジトリに最新バージョンのOpenCV（バージョン3.14.1）をインストールしました。互換性のために、ホームディレクトリの別のフォルダにOpenCV 2（バージョン2.4.13.5）をインストールしました。

g++のコンパイルを容易にするために、.bashrcファイルに各バージョンのエイリアスを作成しました。この設定では、デフォルトでg++ main.cpp $(opencv2).bashrcファイル内の関連コードを次のように使用して、main.cppファイルのみでプログラムをコンパイルできます。

# Programming Related Aliases
# OpenCV
alias opencv3='pkg-config --cflags --libs opencv' # OpenCV 3
opencv2prefix="$HOME/separate-libs/opencv2/release/installed"   # Prefix that serves as the basis for the pathname of the OpenCV 2 directory.
export PKG_CONFIG_PATH="$opencv2prefix/lib/pkgconfig"
export LD_LIBRARY_PATH="$opencv2prefix/lib"
alias opencv2="pkg-config --cflags --libs opencv2"  # OpenCV 2 lib, include and runtime specifications for OpenCV 2. Defined in PKG_CONFIG_PATH.

この設定は、今日初めにOpenCV 2構成を使用してより大きなプログラム（画像分割を実行する）をコンパイルするまでうまく機能しました。最初は、ソースからOpenCV 2をコンパイルするときに必要なビルドオプションを忘れたと思いました。しかし、私の精神状態を確認するために、上記の更新前にOpenCV 2で正常にコンパイルされたプログラムをコンパイルしてみました。結果は次のとおりです。

実行を試み、sudo ldconfigパス名が正しいことを確認しました。また、すべてのファイルの埋め込みステートメントで互換性の問題を確認しましたが、何も見つかりませんでした。 OpenCV 3のインストールに対するパッケージマネージャのアップデートにより、すべてがめちゃくちゃになったようです。しかし、もしそうなら、なぜそうでしょうか？当然、同じフォルダにOpenCVがインストールされているとわかります。しかし、二人はお互いを全く知らず、完全に独立したように見えました。私の唯一の推測はpkg-configに関するものです。

この出力で特に奇妙なことは、* .oファイルが/usr/include/opencv2関数定義を探しているようです。と呼ばれていると$opencv2見てはいけませんか/home/kvasir/separate-libs/opencv2/release/installed/*？

上記のエラーを生成するmakefileは次のとおりです。

また、OpenCV 2バージョンを使用してオブジェクトファイルをコンパイルしてみましたが、成功しませんでした。次のアクションは、おそらくOpenCV 2を再インストールすることです。しかし、なぜこのようなことが起こるのか、それを解決し、今後はこのようなことが発生しないようにする方法があるのだろうか。

さらに、どちらのプログラムもOpenCV 3で問題なく正常にコンパイルできます。たとえば、$(opencv2)上記のmakefileを$（opencv3）に変更すると、エラーは発生せず、プログラムは機能します。

編集：私は大学生であり、このプログラムはコンピュータサイエンスコースの課題でした。上記のより複雑なプログラムは私が書いたものではありません。教授が提供したものであり、他の大学で借りたのです。修正しなければなりませんでしたが、main.cppのmainが空であることを除けばコンパイル可能な状態です。 intに変更してreturnステートメントを作成したreturn 0;ので、OpenCV 3では完全にコンパイルされるようです。

メモ:両方のプログラムのコードが動作することを知っています。コーディングヘルプを探すのではなく、OpenCV 3インストールの更新が/usr/include/別の場所にあるOpenCV 2のカスタムインストールが中断される理由を尋ねています。
