Linux installation Python2.7__linux

The simplest installation steps were found on the Web:

1. Download python2.7.5, save to/data/qtongmon/software
http://www.python.org/ftp/python/

2. Extract Files
Tar xvf python-2.7.5.tar.bz2

3. Create installation directory
Mkdir/usr/local/python27

4. Install Python
./configure--prefix=/usr/local/python27
Make
Make install

5. Modify the old version of Ln pointing (Note: This may affect the use of yum after modification)
mv/usr/bin/python/usr/bin/python2.4.3
Ln-s/usr/local/python27/bin/python/usr/bin/python installation was successful.

As the other modules continued to be installed, the tragedy occurred:

... relocation r_x86_64_32 against ' a local symbol ' can is used when making a shared object; Recompile with-fpic

... could not read Symbols:bad value

Workaround compiler has prompted: Recompile with-fpic

How to compile with this parameter, the original is to recompile python.

./configure--prefix=/usr/local/–enable-shared cflags=-fpic make make install

The recompile succeeded.

But the new problem comes up again:

Libpython2.7.so.1.0:cannot open Shared object file:no such file or directory

Solution:

1. Cp/usr/local/python27/lib/libpython2.7.so.1.0/usr/local/lib

Cd/usr/local/lib

Ln-s libpython2.7.so.1.0 libpython2.7.so

2. Use the command Whereis libpython2.7.so.1.0 get the following results to explain

Libpython2.7.so.1:/usr/local/lib/libpython2.7.so.1.0

Finally get it done ....
