Compiling Python 3.3.2 on CentOS 6.4 - unable to find compiled OpenSSL?


Victor Hooi


We have a machine running CentOS 6.4, and we're attempting to compile Python 3.3.2 on it:

# cat /etc/redhat-release
CentOS release 6.4 (Final)

We've compiled openssl 1.0.1e 11 by hand on this box, and installed it into/usr/local/:

# openssl
OpenSSL> version
OpenSSL 1.0.1e 11 Feb 2013

# ls /usr/local/include/openssl/

However, when we try to build Python 3.3.2, it can't seem to find the SSL installation:

# make
Modules/Setup.dist is newer than Modules/Setup;
check to make sure you have all the updates you
need in your Modules/Setup file.
Usually, copying Modules/Setup.dist to Modules/Setup will work.

Python build finished, but the necessary bits to build these modules were not found:
_dbm _gdbm _lzma
To find the necessary bits, look in in detect_modules() for the module's name.

Failed to build these modules:

I also tried editing the Modules/Setup.dist file, no luck there either.

Any thoughts on what we're doing wrong?

Building them yourself:)

Try for prebuilt packages...
