lxml installation on red hat

Question

I am trying to get python-pptx installed for Python 3 on a server machine (Red Hat 4.1.2-52). I'm having some trouble installing its dependency, lxml. I've tried to install all of the dependencies separately (as suggested here).

# sudo yum install -y gcc libxml2 libxml2-devel libxslt libxslt-devel python-devel

Any ideas what I might be doing wrong? Thanks very much in advance!

If anything, this is a duplicate of this post which also went unanswered...but we got slightly different error messages.

I don't use Red Hat, but my recommendation for you is to follow the instructions from here:

sudo yum install make automake gcc gcc-c++ kernel-devel git-core -y 

sudo yum install python-devel -y 

sudo curl -o /tmp/ez_setup.py https://sources.rhodecode.com/setuptools/raw/bootstrap/ez_setup.py 

sudo /usr/bin/python /tmp/ez_setup.py 

sudo /usr/bin/easy_install pip 

sudo rm setuptools-*.tar.gz 

sudo pip install -i https://pypi.rhodecode.com/ --upgrade pip 

sudo pip install virtualenv

The idea here is that you would install a virtual environment and work with pip packages under it, which is easy and more reliable in terms of dependencies.

While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes. – Wtower Sep 15 '15 at 06:54
@Wtower, I agree with what you mentioned. I will edit the answer. And for kenorb, I thought StackOverFlow was about helping instead of nagging. – Ricardo Silveira Sep 15 '15 at 10:13
@RicardoSilveira Thanks. I'll give it a shot in a virtualenv and report back. – Static Void Sep 15 '15 at 13:34
@RicardoSilveira No luck. I get the same gcc error. – Static Void Sep 18 '15 at 21:43

Please don't use sources.rhodecode.com and pypi.rhodecode.com they will soon disappear :) We're no longer mirror our python stuff internally at RhodeCode.
