I was trying to create a Python Virtual Environment for some initial GIS development. I installed pip and virtualenv and then tried the following commands from the Linux-Terminal to accomplish the task
$ cd Test/virtualenvs_for_test
$ virtualenv --no-site-packages postgis-cb-env
$ source postgis-cb-env/bin/activate
$ pip install gdal
But found the following error message:
error: command 'gcc' failed with exit status 1
Cleaning up…

I have no sure idea what this error is exactly. Although initial web-hunting suggested a need to change encoding from ascii to utf8, but how?

You must install libgdal-dev and then install gdal with paths:
