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_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':

See `config.log' for more details

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

Answer 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.
