I asked this question on Stack Overflow before I realised this site existed. As this site it more appropriate, I'll ask it here too.
I'm trying to install gdal from pip
pip install gdal inside a virtual environment (Ubuntu). It fails because it cannot find
extensions/gdal_wrap.cpp:2853:22: fatal error: cpl_port.h: No such file or directory compilation terminated
However GDAL is installed correctly and the header file is located at
/usr/include/gdal/cpl_port.h. Is there some environment variable for GDAL that needs to be set in order for pip to find the header files?
