can't find libjpeg.so.8 while compling caffe (under py-faster-rcnn/caffe-fast-rcnn) when it's there

[Chan Kim]

Hi,

I've succeeded this path a couple of days ago but somehow doing it again, but me with this trouble.

I'm following this page (http://caffe.berkeleyvision.org/installation.html)

while compiling, when I do 'make all'

I see

...

CXX/LD -o .build_release/tools/net_speed_benchmark.bin

CXX/LD -o .build_release/tools/caffe.bin

/usr/bin/ld: warning: libjpeg.so.8, needed by /home/ckim/anaconda2/lib/libopencv_highgui.so, not found (try using -rpath or -rpath-link)

/usr/bin/ld: warning: libpng16.so.16, needed by /home/ckim/anaconda2/lib/libopencv_highgui.so, not found (try using -rpath or -rpath-link)

/home/ckim/anaconda2/lib/libopencv_highgui.so: undefined reference to `png_set_filter@PNG16_0'

/home/ckim/anaconda2/lib/libopencv_highgui.so: undefined reference to `png_get_IHDR@PNG16_0'

...

/home/ckim2/anaconda2/lib/libopencv_highgui.so is looking for libjpeg.so.8. 

Actually the libjpeg.so.8 file (it's a symbolic link pointing to libjpeg.so.8.4.0 in the same location /home/ckim2/anaconda2/lib/)

inside Makefile.config,

ANACONDA_HOME := $(HOME)/anaconda2

PYTHON_INCLUDE := $(ANACONDA_HOME)/include \

        $(ANACONDA_HOME)/include/python2.7 \

        $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include \

and the Makefile includes this Makefile.config

I dont't know why the compiler can't find the libjpeg8.so file when it's in the lib path, and also I don't know how to use -rath or -rpath-link.

Can anyone help me?

I'm doing it on CentOS6.7.

Thanks,

Chan

I solved it by adding entry for anaconda lib directory using /etc/ld.so.conf (and lower directory).

But I'm seeing new error saying..

..

XX/LD -o .build_release/examples/mnist/convert_mnist_data.bin

CXX/LD -o .build_release/examples/cifar10/convert_cifar_data.bin

CXX/LD -o .build_release/examples/siamese/convert_mnist_siamese_data.bin

/home/ckim/anaconda2/lib/libpng16.so.16: undefined reference to `inflateReset2@ZLIB_1.2.3.4'

collect2: ld returned 1 exit status

/home/ckim/anaconda2/lib/libpng16.so.16: undefined reference to `inflateReset2@ZLIB_1.2.3.4'

collect2: ld returned 1 exit status

/home/ckim/anaconda2/lib/libpng16.so.16: undefined reference to `inflateReset2@ZLIB_1.2.3.4'

collect2: make: *** [.build_release/tools/device_query.bin] Error 1

ld returned 1 exit status

...

libpng16.so.16 calls inflateReset2@ZLIB_1.2.3.4. I can see inflateReset2 function is in ~/anaconda2/lib/libz.so.

That lib directory is in the -L option (using PYTHON_LIB) and ld also knows the path.

How can I fix this?

regarding the first problem installing jpeg by anaconda would resolve the issue. you have to make sure you have library path of anaconda included in the make file as well as include path which you've shown here.

regarding the second problem I had this issue before I resolved it by installing a libpng15 and put it in a folder in anaconda library and adding its path in bash file.
