Error installing mod_wsgi in centos with python2.7

  • 772

When i do "make" in mod_wsgi folder i get this error

I configured using following

./configure --with-apxs=/usr/local/apache/bin/apxs   --with-python=/opt/python27/bin/python

/usr/bin/ld: /opt/python27/lib/libpython2.7.a(node.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /opt/python27/lib/libpython2.7.a: could not read symbols: Bad value collect2: ld returned 1 exit status apxs:Error: Command failed with rc=65536

This link has the solution but i could not understand it fully

1)How can i found that i have compiled x32bit or x64 bit version of python 
2)I didn't understand about what symbolic link he was talking about
centos mod-wsgi python

    The important bit is to rebuild Python with --enable-shared. The symlink comments are not relevant if you haven't done that and should't even apply with recent Python/mod_WSGI versions.

  2. Re-compile Python

    Re-compiling Python with --enable-shared alone is not enough, because you'll get error while loading shared libraries.

    Supposed that you will install Python 2.7.x in /usr/local/bin, you should configure it with LDFLAGS option:

    cd Python-2.7.x
make distclean  # For re-compiling only
./configure --enable-shared --prefix=/usr/local LDFLAGS="-Wl,--rpath=/usr/local/lib"
make
sudo make altinstall

    (Use altinstall instead of install to avoid changing symbolic links of system Python and man pages. In short, install = altinstall + bininstall + maninstall)

    Compile mod_wsgi

    Supposed that (a compiled version of) Apache is installed in /usr/local/apache, compile mod_wsgi against Python 2.7 like this:

    cd mod_wsgi-x.x.x
./configure LDFLAGS="-Wl,--rpath -Wl,/usr/local/lib" --with-apxs=/usr/local/apache/bin/apxs --with-python=/usr/local/bin/python2.7
make
sudo make install

    If you compile mod_wsgi without LDFLAGS, Apache will complain:

    Cannot load /usr/local/apache/modules/mod_wsgi.so into server: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
