compile python 3.3 with bz2 support

[Isml]

hi, everyone:

    I want to compile python 3.3 with bz2 support on RedHat 5.5 but fail to do that. Here is how I do it:

    1. download bzip2 and compile it(make、make -f Makefile_libbz2_so、make install)

    2.chang to python 3.3 source directory : ./configure --with-bz2=/usr/local/include

    3. make

    4. make install

 

    after installation complete, I test it：

    [root@localhost Python-3.3.0]# python3 -c "import bz2"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python3.3/bz2.py", line 21, in <module>
    from _bz2 import BZ2Compressor, BZ2Decompressor
ImportError: No module named '_bz2'

By the way, RedHat 5.5 has a built-in python 2.4.3. Would it be a problem?

Why can't you use yum? (yum install libbz2-dev)

IMO it's a linker problem. If libbz2.zo is in /usr/local/lib then try
LB_LIBRARY_PATH=/usr/local/lib python3 -c 'import bz2'

If this work, you can add /usr/local/lib to the linker by doing:
echo /usr/local/lib >> /etc/ld.so.conf.d/local.conf
ldconfig

Having said that, if the yum way work - do it.

I don't think so. I have multiple version of Python on RedHat systems.

What is the output of configure? The last thing it does is list which modules are not going to be built. Is bz2 on the list? What does configure say when it's looking for bz2?

sudo apt-get install libbz2-dev

Python-3.4.1$ ./configure --with-pydebug --with-bz2 --prefix=/usr && make -j2
