compile python 3.3 with bz2 support
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 "", line 1, in File "/usr/local/lib/python3.3/bz2.py", line 21, in 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?-- http://mail.python.org/mailman/listinfo/python-list

Thanks for your reply.According to your advice, I tried again, but still failed. Here is how I do this time: 1. I did not find package "libbz2-dev" in my source, so I still install it from source 2. I carefully checked the output of "./confiruge" this time and find a warning : "configure: WARNING: unrecognized options: --with-bz2"?? so I used a wrong param? 3. I checked the build-in Python 2.4.3 which can successfully "import bz2"??and find a "bz2.so" in it's lib dir(/usr/lib/python2.4/lib-dynload/bz2.so)??I check the dependency of this file [root@localhost lib-dynload]# ldd /usr/lib/python2.4/lib-dynload/bz2.so linux-gate.so.1 => (0x002a) libbz2.so.1 => /usr/lib/libbz2.so.1 (0x00336000) libpthread.so.0 => /lib/libpthread.so.0 (0x00fa5000) libc.so.6 => /lib/libc.so.6 (0x00128000) /lib/ld-linux.so.2 (0x003e5000) it seems that the redhat has already installed the libbz2.so. But I failed to find such a file in my own compiled python 3.3 lib dir(/usr/local/lib/python3.3/lib-dynload/), strangely I see a file named "_bz2.cpython-33m_failed.so", the name indicated that it is not a right file. I renamed it to bz2.so and tried again, finally get a error: >>> import bz2 Traceback (most recent call last): File "", line 1, in ImportError: dynamic module does not define init function (PyInit_bz2) -- -- ??: "Benjamin Kaplan"; : 2012??12??23??(??) 0:06 ??: "Python List"; : Re: compile python 3.3 with bz2 support On Dec 21, 2012 1:31 AM, "Isml" <76069...@qq.com> wrote: > > hi, everyone: > I want to compile python 3.3 with bz2 support on RedHat 5.5 but fail to > do that.

Finally I worked it out. I write it down Here to people who meet the same problem like me. 1. Install bzip2 from source is OK 2. There is no need to add "--with-bz2" to "./configure", because it is not a valid param. python makefile will search the bz2 itself, if it find the bz2 lib, it will automatically compile this module. see setup.py line 1373. So the "./configure" outputs the warning : "configure: WARNING: unrecognized options: --with-bz2" 3. The reason why I failed before is that I did not correctly compile the bz2.so, the filename "_bz2.cpython-33m_failed.so" has indicated that fact. And the reason why I faild to compile bz2.so is strangely the RedHat "SELinux". So the only thing I then do is disable it (setenforce 0), after that, everything is OK.
