Trouble Installing Cutadapt On A Linux Machine

Question

[agatorano]

I run: sudo python setup.py build

this yields this error message

running build

running build_ext

I have no clue whey this would occur but similar messages have popped up what installing other things as well.

The Python.h file is not in under the '-I' path. Check that you have installed the development files for python. Under ubuntu it should be something like:

sudo apt-get install python-dev

Thank you! that did it. Wish I knew about all of these required installs before reaching all of these roadblocks
