pycrypto on Ubuntu giving compiler error

Question

I am trying to install pycrypto2.6 on Ubuntu 10.04 (Lucid Lynx) with Python 2.7.3.

I am encountering the following error:

running build
running build_py
running build_ext
running build_configure
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in `/home/pratibha/Desktop/pycrypto-2.6':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details

RuntimeError: autoconf error

I checked Software Centre, and I have GCC installed on my system, but the "which gcc" command is not returning any path.

I got it by creating the symbolic link:

ln -s /usr/bin/gcc-4.4 /usr/bin/gcc

Solution 1

I had a similar problem, but in my case it turns out I didn't have gcc installed at all.

So a simple sudo apt-get install gcc did the trick.

If you have it installed, but which gcc doesn't return any path, then go to /usr/bin/ and look for gcc. Then create a symbolic link, like so:

ln -s /usr/bin/gcc-<version-number> /usr/bin/gcc

where you replaced <version-number> with the appropriate version number, of course.

Solution 2

I ran into a similar error message when installing pycrypto on a shared host (Webfaction). The solution was to change the temporary directory while installing:

TMPDIR=~/tmp pip install pycrypto

Solution 3

I was having the same problem, and trying the above step of installing gcc did not help.

Once I installed the python-dev package, everything compiled perfectly.

sudo apt-get install python-dev

Hello pratibha, please don't add "[solved]" to your question title, this isn't how this site works. Post your answer as an answer (you'll be able to do that in a while). If you already know the answer when posting, there's a button for that in the question editor.

Thanks, this answer helped me with with a box I was trying to pip install paramiko that had noexec for /tmp

$ which gcc /usr/bin/gcc And still not working.

Unfortunately this did not help, still getting the above error.

This is a wrong solution for the original problem. Helps in another situation.

This works for me, ensure gcc AND python-dev are installed

I had this same problem on a shared Webfaction server, Centos 7. This solution worked perfectly, thanks.

mkdir ~/tmp and then it worked for me (duh), on CentOS.
