的Makefile的OpenCV停止工作

我使用OpenCV的的Makefile的OpenCV停止工作

CFLAGS = `pkg-config --cflags opencv` 
LIBS = `pkg-config --libs opencv` 

% : %.cpp 
    g++ $(CFLAGS) -o [email protected] $< $(LIBS)

這工作得很好，直到最近纔有下面的Makefile的項目。我現在得到了以下錯誤：

/usr/bin/ld: cannot find -lcufft 
/usr/bin/ld: cannot find -lnpps 
/usr/bin/ld: cannot find -lnppi 
/usr/bin/ld: cannot find -lnppc 
/usr/bin/ld: cannot find -lcudart

pkg-config --libs opencv輸出：

/usr/local/lib/libopencv_calib3d.so 
/usr/local/lib/libopencv_contrib.so 
/usr/local/lib/libopencv_core.so 
/usr/local/lib/libopencv_features2d.so 
/usr/local/lib/libopencv_flann.so 
/usr/local/lib/libopencv_gpu.so

/usr/local/lib/libopencv_ml.so

/usr/lib/x86_64-linux-gnu/libGLU.so 
-lcufft -lnpps -lnppi -lnppc -lcudart -ltbb -lrt -lpthread -lm -ldl

我已經出口到LD_LIBRARY_PATH的CUDA庫路徑：

echo $LD_LIBRARY_PATH 
/usr/local/cuda-5.5/lib64

此路徑確實包含了庫：

ls $LD_LIBRARY_PATH 
libcublas_device.a libcudart.so.5.0  libcufftw.so   libcurand.so.5.5  libnppc.so.5.5.22 libnvToolsExt.so 
libcublas.so   libcudart.so.5.5  libcufftw.so.5.5  libcurand.so.5.5.22 libnppi.so   libnvToolsExt.so.1 
libcublas.so.5.0  libcudart.so.5.5.22 libcufftw.so.5.5.22 libcusparse.so   libnppi.so.5.5  libnvToolsExt.so.1.0.0 
libcublas.so.5.5  libcudart_static.a libcuinj64.so   libcusparse.so.5.5  libnppi.so.5.5.22 
libcublas.so.5.5.22 libcufft.so   libcuinj64.so.5.5  libcusparse.so.5.5.22 libnpps.so 
libcudadevrt.a  libcufft.so.5.5  libcuinj64.so.5.5.22 libnppc.so    libnpps.so.5.5 
libcudart.so   libcufft.so.5.5.22 libcurand.so   libnppc.so.5.5   libnpps.so.5.5.22

但我仍然得到錯誤。我運行opencv 2.4.9和cuda 5.5。我忘了什麼？

你有沒有嘗試用'-L'在Makefile中添加cuda庫的路徑？也許這裏有一個答案http://stackoverflow.com/questions/1904990/what-is-the-difference-between-ld-library-path-and-l-at-link-time –

我現在做了這個：' g ++ -L/usr/local/cuda-5.5/lib64''pkg-config --cflags opencv'' -o writeFramesMainSimple writeFramesMainSimple.cpp'' pkg-config --libs opencv'它工作正常！儘管如此，我仍然不明白爲什麼它會停止工作，因爲這正是'LD_LIBRARY_PATH'中的內容。根據你的鏈接，這應該很好...... – BdB

我現在這樣做：g++ -L /usr/local/cuda-5.5/lib64 pkg-config --cflags opencv -o writeFramesMainSimple writeFramesMainSimple.cpp pkg-config --libs opencv和它的工作！

LD_LIBRARY_PATH用於運行時。編譯時需要使用LIBRARY_PATH。要麼你出口/usr/local/cuda-5.5/lib64到LIBRARY_PATH或者您在Makefile中添加路徑LIBS：

LIBS += -L/usr/local/cuda-5.5/lib64

LD_LIBRARY_PATH vs LIBRARY_PATH

我將'/ usr/local/cuda-5.5/lib64'導出到'LIBRARY_PATH'。現在我得到'/ usr/bin/ld：跳過不兼容的/usr/local/cuda-5.5/lib64/../lib/libcufft.so搜索-lcufft /usr/bin/ld：跳過不兼容的/ usr/local/cuda-5.5/lib64 /../ lib/libnpps.so搜索-lnpps /usr/bin/ld：跳過不兼容的/usr/local/cuda-5.5/lib64/../lib/libnppi.so當搜索-lnppi /usr/bin/ld時：跳過不兼容的/usr/local/cuda-5.5/lib64/../lib/libnppc.so/usr/bin/ld：跳過不兼容的/ usr/local/cuda-5.5/lib64 /../ lib/libcudart.so當搜索-lcudart'時 – BdB
