以下はcmakeがMakefileファイルを生成してCaffeを静的ライブラリ接続コンパイルするためのshellスクリプトです.

スクリプトでは、cmakeを呼び出してMakefileを生成する際に、libstdc+、libgccを静的ライブラリ形式で接続することを指定するために-DCMAKE_EXE_LINKER_FLAGS="-static-libstdc++ -static-libgcc"のパラメータが追加するが、実際の使用過程では、USE_OPENCV=on(すなわちOpenCVを使用するopencvが静的ライブラリコンパイルされている)を指定した場合、コンパイルされたcaffeはlddで見るもlibstdc++に依存することが分かった.soとlibgcc.so、つまり-static-libstdc++ -static-libgcc無効になりました..USE_OPENCV=offの場合、正常に静的に接続できます.
この問題は数日困っていたが、.dirのlinkを比較した.txt(cmake生成)では、USE_OPENCV=onで生成するlinkが発見された.txtではopencv静的ライブラリに-lstdc++パラメータが自動的に追加されます.の以下はcaffe.binプロジェクトlink.txt(./tools/CMakeFiles/caffe.bin.dir/link.txt)、長すぎて支店を追加しました:

この末尾の-lstdc++パラメータが-static-libstdc++ -static-libgccを無効にし、-lstdc++を手動で削除しようとすると、コンパイルが通過し、stdc++、libgccが静的に接続されます.そこでcmakeでMakefileを生成した後、次のコードを追加すると、問題は解決します.
#      link.txt   -lstdc++   ，      libstdc++ ,   USE_OPENCV=on    ，libstdc++      
for file in $(find . -name link.txt)
do 
    echo "modifing file: $file"
    #sed -i -r "s/-lstdc\+\+/ /g" $file
done

静的コンパイル後、lddはbinのcaffe依存関係を表示し、システムライブラリ以外の動的ライブラリに依存せず、ファイルサイズも28 MBに達した.

しかし、なぜopencvのライブラリがこの問題を引き起こすのか.ずっと分からなかった.
