Hi,
I'm trying to build GDAL bindings for Python 3. I have the gdal-2.2.2-1 package installed from the Arch Linux official repositories, which does contain bindings for Python 2.7. PYTHONPATH=/usr/lib/python2.7/site-packages/osgeo python2
from osgeo import gdal
exit()
python3
from osgeo import gdal
Traceback (most recent call last): File "<stdin>", line 1, in <module> ModuleNotFoundError: No module named 'osgeo' But when I try to build the bindings for Python 3myself (have tried using the python-gdal package from Arch's AUR, building it manually, and using easy_install GDAL), I get the following error: ➜ Desktop sudo easy_install GDAL Searching for GDAL Reading https://pypi.python.org/simple/GDAL/ Downloading https://pypi.python.org/packages/11/cd/edef955a6ef6cb4f2113647d7465b34663e074451b66919e734466ba5197/GDAL-2.2.2.tar.gz#md5=bc5a58ec0e82420fdc910bafc3b5800a Best match: GDAL 2.2.2 Processing GDAL-2.2.2.tar.gz Writing /tmp/easy_install-jom80hpq/GDAL-2.2.2/setup.cfg Running GDAL-2.2.2/setup.py -q bdist_egg --dist-dir /tmp/easy_install-jom80hpq/GDAL-2.2.2/egg-dist-tmp-tf275y_9 cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ extensions/osr_wrap.cpp:3339:13: warning: ‘void GDALPythonFreeCStr(void*, int)’ defined but not used [-Wunused-function] static void GDALPythonFreeCStr(void* ptr, int bToFree) ^~~~~~~~~~~~~~~~~~ extensions/osr_wrap.cpp:3309:14: warning: ‘char* GDALPythonObjectToCStr(PyObject*, int*)’ defined but not used [-Wunused-function] static char* GDALPythonObjectToCStr(PyObject* pyObject, int* pbToFree) ^~~~~~~~~~~~~~~~~~~~~~ cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ extensions/gnm_wrap.cpp:3321:13: warning: ‘void GDALPythonFreeCStr(void*, int)’ defined but not used [-Wunused-function] static void GDALPythonFreeCStr(void* ptr, int bToFree) ^~~~~~~~~~~~~~~~~~ extensions/gnm_wrap.cpp:3291:14: warning: ‘char* GDALPythonObjectToCStr(PyObject*, int*)’ defined but not used [-Wunused-function] static char* GDALPythonObjectToCStr(PyObject* pyObject, int* pbToFree) ^~~~~~~~~~~~~~~~~~~~~~ cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ In file included from /usr/include/python3.6m/numpy/ndarraytypes.h:1809:0, from /usr/include/python3.6m/numpy/ndarrayobject.h:18, from /usr/include/python3.6m/numpy/arrayobject.h:4, from extensions/gdal_array_wrap.cpp:3464: /usr/include/python3.6m/numpy/npy_1_7_deprecated_api.h:15:2: warning: #warning "Using deprecated NumPy API, disable it by " "#defining NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" [-Wcpp] #warning "Using deprecated NumPy API, disable it by " \ ^~~~~~~ extensions/gdal_array_wrap.cpp: In function ‘void GDALRegister_NUMPY()’: extensions/gdal_array_wrap.cpp:3528:45: error: ‘GDALCreateDriver’ was not declared in this scope poDriver = static_cast<GDALDriver*>(GDALCreateDriver()); ^~~~~~~~~~~~~~~~ extensions/gdal_array_wrap.cpp:3528:45: note: suggested alternative: ‘GDALGetDriver’ poDriver = static_cast<GDALDriver*>(GDALCreateDriver()); ^~~~~~~~~~~~~~~~ GDALGetDriver extensions/gdal_array_wrap.cpp: At global scope: extensions/gdal_array_wrap.cpp:3448:13: warning: ‘void GDALPythonFreeCStr(void*, int)’ defined but not used [-Wunused-function] static void GDALPythonFreeCStr(void* ptr, int bToFree) ^~~~~~~~~~~~~~~~~~ extensions/gdal_array_wrap.cpp:3418:14: warning: ‘char* GDALPythonObjectToCStr(PyObject*, int*)’ defined but not used [-Wunused-function] static char* GDALPythonObjectToCStr(PyObject* pyObject, int* pbToFree) ^~~~~~~~~~~~~~~~~~~~~~ error: Setup script exited with error: command 'gcc' failed with exit status 1 Any ideas?
