Installing gdal python package inside Python27 Software Collection

Question

I have a Centos 6.6 VM with the Python 2.7 SCL. I have gdal and gdal-devel installed.

If I start the scl with sudo scl enable python27 bash and do a pip install gdal it fails on:

gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -fPIC -I../../port -I../../gcore -I../../alg -I../../ogr/ -I/opt/rh/python27/root/usr/include/python2.7 -I. -I/usr/include -c extensions/gdal_wrap.cpp -o build/temp.linux-x86_64-2.7/extensions/gdal_wrap.o

What's the right way to get gdal in /opt/rh/python27/root/usr/include/ or make pip point gcc to /usr/include/?

Answer 1

I got this working in a virtual environment by modifying this method.

There were two issues. First I had to specifically use the gdal module version 1.9.1. 1.10.0 and 1.11.0 will not work with version 1.9.2 of the core gdal library, which is what redhat ships with. Secondly I had to pass -I/usr/include/gdal to gcc. The sequence is as follows:

# you might need to do a sudo -s if your virtualenv is owned by root.
scl enable python27 bash
cd $VIRTUENV_ROOT
source bin/activate
pip install --no-install gdal==1.9.1
cd build/gdal
python setup.py build_ext \
  --gdal-config=/usr/bin/gdal-config \
  --include-dirs=/usr/include/gdal/
python setup.py install

A virtual environment isn't strictly necessary, but I don't know where the global python build folder is.
