Hey GDAL Team - I have a server running CentOS 6. I have downloaded the
complete 1.11.2 source and successfully built and installed GDAL.
I am now trying to make my C++ program which uses GDAL and I’m not
having any luck. I get an “unknown reference” error on all my calls to
GDAL methods. (GDALAllRegister, GDALOpen, etc).
On my #include I get an error if I use #include “gdal/gdal_priv.h”; but
it makes it past that point if I use #include “gdal_priv.h” alone.
#include "gdal_priv.h" is the proper syntax. If you use a pre-built
package from ubuntu or fedora or other package maintainer, they
sometimes install the headers in a folder named gdal. The standard
build does not.
I am using cmake with this project and here is my CMakeLists.txt below.
I have manually set GDAL_INCLUDE_DIRS to be /usr/local/lib which is
where all the libgdal*.so files are located.
I believe the proper name is GDAL_INCLUDE_DIR and it needs to point to
the headers so it should be /usr/local/include (assuming a standard
installation, see above).
cmake_minimum_required(VERSION 2.8)
project( AerialMask )
find_package( OpenCV )
find_package( GDAL )
include_directories(
${OpenCV_INCLUDE_DIRS}
${GDAL_INCLUDE_DIRS}
)
add_executable( AerialMask AerialMask.cpp )
target_link_libraries( AerialMask ${OpenCV_LIBS} )
You need to link to libgdal, so:
target_link_libraries( AerialMask ${OpenCV_LIBS} ${GDAL_LIBRARY} )
