Compile on Ubuntu 14.04?

[mrgloom]

What proper apt-get install command for gdal library?

List of my installed packages:

apt list --installed | grep gdal

gdal-bin/trusty,now 1.10.1+dfsg-5ubuntu1 amd64 [installed,automatic]
libgdal-dev/trusty,now 1.10.1+dfsg-5ubuntu1 amd64 [installed]
libgdal1h/trusty,now 1.10.1+dfsg-5ubuntu1 amd64 [installed,automatic]
python-gdal/trusty,now 1.10.1+dfsg-5ubuntu1 amd64 [installed]

Howewer:

cmake ..

CMake Error at src/CMakeLists.txt:10 (message):
  The GDAL version must be one that implements RFC 46 (GDAL/OGR unification)
  i.e.  >= 2.0.0

Do we need to build gdal from source?

you do not need to build gdal from source.you can just install it.my os is macox,you can see this http://gis.stackexchange.com/questions/155403/installing-gdal-on-macosx

Problem is that on Ubuntu 14.04 by default apt-get install install some older version than cesium-terrain-builder need for compile:

sudo apt-get install gdal-bin
sudo apt-get install python-gdal
sudo apt-get install libgdal-dev

I have compiled gdal from source:

#For cesium-terrain-builder we need GDAL version >= 2.0.0
#Build gdal from source https://trac.osgeo.org/gdal/wiki/BuildingOnUnix
#All versions http://download.osgeo.org/gdal/
#Build with python support https://gis.stackexchange.com/questions/21728/installing-gdal-1-9-0-on-linux-ubuntu-server-10-04/21739#21739
wget http://download.osgeo.org/gdal/2.1.3/gdal-2.1.3.tar.gz
tar -xvzf gdal-2.1.3.tar.gz
cd gdal-2.1.3
mkdir build
./configure --with-python --prefix=`pwd`/build
sudo make
sudo make install

But how to specify location of the gdal to cmake?

-- Could NOT find GDAL (missing:  GDAL_LIBRARY GDAL_INCLUDE_DIR) 
CMake Error at CMakeLists.txt:67 (message):
  The GDAL library cannot be found on the system


-- Configuring incomplete, errors occurred!

It's something like:
~/Downloads/cesium-terrain-builder/build$ cmake -D GDAL_LIBRARY="/home/user/Downloads/gdal-2.1.3/build/lib" -D GDAL_INCLUDE_DIR="/home/user/Downloads/gdal-2.1.3/build/include" ..

But it produces error (seems same as here #15 ):

-- Found GDAL: /home/user/Downloads/gdal-2.1.3/build/lib  
-- Looking for GDALOpenEx in gdal
-- Looking for GDALOpenEx in gdal - not found
CMake Error at src/CMakeLists.txt:10 (message):

  i.e.  >= 2.0.0


-- Configuring incomplete, errors occurred!

Howewer my gdal builded from source:

./gdal-config --version
2.1.3
./gdalinfo --version
GDAL 2.1.3, released 2017/20/01

After adding GDAL_CONFIG:

~/Downloads/cesium-terrain-builder/build$ cmake -D GDAL_LIBRARY="/home/user/Downloads/gdal-2.1.3/build/lib" -D GDAL_INCLUDE_DIR="/home/user/Downloads/gdal-2.1.3/build/include" -D GDAL_CONFIG="/home/user/Downloads/gdal-2.1.3/build/bin/gdal-config" ..
CMake Error at src/CMakeLists.txt:10 (message):
  The GDAL version must be one that implements RFC 46 (GDAL/OGR unification)
  i.e.  >= 2.0.0

Also I can find GDALOpenEx function in headers:

~/Downloads/gdal-2.1.3/build/include$ grep -n -r GDALOpenEx .
./gdal_priv.h:298:    friend GDALDatasetH CPL_STDCALL GDALOpenEx( const char* pszFilename,
./gdal.h:358: * Used by GDALOpenEx().
./gdal.h:364: * Used by GDALOpenEx().
./gdal.h:370: * Used by GDALOpenEx().
./gdal.h:376: * Used by GDALOpenEx().
./gdal.h:382: * Used by GDALOpenEx().
./gdal.h:389: * Used by GDALOpenEx().
./gdal.h:402: * Used by GDALOpenEx().

./gdal.h:447: * Used by GDALOpenEx().
./gdal.h:455:GDALDatasetH CPL_DLL CPL_STDCALL GDALOpenEx( const char* pszFilename,

Howerwer commenting out this condition not helped:

#check_library_exists(gdal GDALOpenEx "${GDAL_LIBRARY_DIR}" HAVE_UNIFIED_GDAL)
#if(NOT MSVC AND NOT HAVE_UNIFIED_GDAL)
#  message(FATAL_ERROR "The GDAL version must be one that implements RFC 46 (GDAL/OGR unification) i.e. >= 2.0.0")
#endif()

Seems this solve the problem(don't know what make a trick gdal version 2.0.1 or ./configure without prefix):

wget http://download.osgeo.org/gdal/2.0.1/gdal-2.0.1.tar.gz
tar -xvzf gdal-2.0.1.tar.gz
cd gdal-2.0.1
mkdir build
./configure --with-python
sudo make
sudo make install
