python new install showing error while loading shared libraries

Question

i installed python2.6 before in

/ust/local/bin

but now i removed it and installed a new python2.6.4 in

/opt/python2.6

i installed from the article

but on mid way only where they say to check python it says

[root@domain ~]# python
 /opt/python2.6/bin/python: error while loading shared libraries: libpython2.6.so.1.0: cannot open shared object file: No such file or directory

but when i open

/opt/python2.6/lib

i can found this file. please tell me whats wrong with this?

Solution 1

When you compile python2.6 with --prefix=/opt/python2.6, the binaries will be installed at /opt/python2.6/bin, the libraries at /opt/python2.6/lib, ...

/opt/python2.6/bin/python: error while loading shared libraries: libpython2.6.so.1.0: cannot open shared object file: No such file or directory

This error means that python is not looking at the path the file is in. So you need to add the library path to /etc/ld.so.conf file and activate it with ldconfig:

# echo "/opt/python2.6/lib" > /etc/ld.so.conf.d/libpython2.6.conf
# ldconfig

Solution 2

in Step 2 try add LDFLAGS with right path... for example

env LDFLAGS="-L/opt/python2.6/lib -R/opt/python2.6/lib" ./configure --prefix=/opt/python2.6 --with-threads --enable-shared
