#35273 — compile python 3.3 with bz2 support

[Multipart message — attachments visible in raw view] — view raw

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.
