Hello,
I downloaded a code recently from a Github repo for doing non-rigid 3D object reconstruction from videos. The code has many dependencies on other libraries, among which is the OpenCV library. Unfortunately, when I build the code, I get the following error message:
CXX/LD -o build/PangaeaTracking/bin/PangaeaTracking_console
/usr/bin/ld: /usr/local/lib/libopencv_core.a(persistence.cpp.o): undefined reference to symbol 'gzclose'
//lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:127: recipe for target 'build/PangaeaTracking/bin/PangaeaTracking_console' failed
make: *** [build/PangaeaTracking/bin/PangaeaTracking_console] Error 1
I am building it on Ubuntu 16.04 and have installed opencv 2.4.13 correctly, made sure that this the case as follows:
$ pkg-config --cflags opencv
-I/usr/local/include/opencv -I/usr/local/include
The library dependencies in my makefile are:
# Library dependencies
GL_LIB := -lGL -lGLU -lX11 -lGLEW
WX_LIB := `wx-config --libs --gl-libs`
BOOST_LIB := -lboost_filesystem -lboost_system -lboost_thread
OPENCV_LIB := -lopencv_core -lopencv_highgui -lopencv_imgproc
CERES_LIB := -lceres -lglog -ltbb -ltbbmalloc -lcholmod -lccolamd \
-lcamd -lcolamd -lamd -lsuitesparseconfig -llapack -lf77blas -latlas
LMDB_LIB := -llmdb
HDF5_LIB := -lhdf5_hl -lhdf5
LIBRARY_DIRS += $(LIB_BUILD_DIR)
LDFLAGS := $(WX_LIB) $(BOOST_LIB) $(OPENCV_LIB) $(CERES_LIB) $(GL_LIB) $(LMDB_LIB) $(HDF5_LIB)
LDFLAGS += $(foreach library_dir, $(LIBRARY_DIRS), -L$(library_dir))
I would be grateful if anybody has an idea about the possible cause of this error.
