以下を使用してOpenCVを正常に構築しました。このLinuxインストールチュートリアル以前はUbuntuディストリビューションでビルドしていましたが、最近はArch Linuxディストリビューションでビルドする必要がありました。
このコマンドは、
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. -Wno-dev 次の行を含むエラーがないように見えるログを生成します。
Detected version of GNU GCC: 52 (502)
... <skipped lines> ...
C Compiler: /usr/bin/cc
ただし、コマンドを実行すると、make次のエラーが発生します。
/usr/bin/gcc-5: No such file or directory
CMake Error at cuda_compile_generated_gpu_mat.cu.o.cmake:208 (message): Error generating /home/cecilia/opencv-3.0.0/build/modules/core/CMakeFiles/cuda_compile.dir
/src/cuda/./cuda_compile_generated_gpu_mat.cu.o
これは明らかに間違った方法です。gccはいusr/bin/gcc。gccシステムパスにあることを再確認するためにgcc -v本番を実行しました。

cmake正しいgccバージョンが検出されたが、make間違ったパスが使用されたのはなぜですか？このエラーをどのように解決できますか？

cmake以前に設定されたすべての変数を上書きするとし、Ubuntuコンピュータからopencvディレクトリをコピーしました。ところで、CMakeCache.txtを上書きせず、パスが誤って認識されるようです。
簡単な修正：
- 以下からきれいなopencvディストリビューションをダウンロードしてください。http://opencv.org/
- 前のようにチュートリアルに従ってください。
