Php Error While Loading Shared Libraries Libpq.so.4

The same applies when you remove a shared library. Select Only Printed Out Cells What kind of weapons could squirrels use? After this, env-update runs ldconfig so that it reloads the cache of libraries into the /etc/ld.so.cache file. Otherwise you get an error like ldd: ./ls: No such file or directory. Check This Out

In general I think that the post's how-to outline of using ldd, find, echo, and ldconfig, while being less KISS-ish than your approach, is worth the extra time, effort, and complexity. As it stands now, this script will only check the first layer of library dependencies. What's the difference in sound between the letter η and the diphthong ει? Troubleshooting In some cases, a program may have been hard coded to look for a specific library on your system in a certain path, thus ignoring your local library settings. http://stackoverflow.com/questions/12781566/error-while-loading-shared-libraries-libpq-so-5-cannot-open-shared-object-file

Also, when programs are statically linked, they can't take advantage of updates made to the libraries that they depend on. While I like package managers I've occasionally had to resort to binary files and library dependencies are a headache. Paula 2010/04/17 at 12:05 AM Brilliant article to help troubleshoot library dependencies .

In order to fix this problem, you can research what version/path of the library the program is looking for and then create a symbolic link between the expected library location and As I mentioned in the Background section, you need to be aware of dependency chains when using shared libraries. The /etc/ld.so.cache file is formatted in binary by ldconfig and so it's not designed to be human readable, and should not be edited by hand. reply | permalink Surabhi Ahuja I give the following command now to compile sample.c gcc -o sample sample.c -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -rpath/usr/local/pgsql/lib - lpq it gives this message: gcc: unrecognized option `-rpath/usr/local/pgsql/lib'

Keep up the good work man. You can find the correct directory with: find /usr/local -name 'libpg.so.3' There should be something on this in the installation instructions. library="$(echo $line | cut -d ":" -f 1)" printf "Executable %s is missing shared object %sn" $exe $library fi done fi done When run on the /opt/PostgreSQL directory mentioned above, it

The system just doesn't notice the new library, thus ldconfig tells the system to "go check again". This variable is typically not set by default on Linux distributions, and should not be used as a permanent fix. DirectAdmin 2013 JBMC Software Grokbase › Groups › PostgreSQL › pgsql-general › February 2005 FAQ Badges Users Groups [PostgreSQL] error while loading shared libraries: libpq.so.3 Surabhi AhujaFeb 21, 2005 at It won't # if the executable is something like a script or a non-ELF executable.

There are also a couple of other situations that you're likely to encounter with this linking scheme. https://sachinpradeeplinux.wordpress.com/2013/02/13/php-error-while-loading-shared-libraries-libpq-so-3-cannot-open-shared-object-file-no-such-file-or-directory/ The only way to work around giving ldd the full path is to use cd to change into the directory where the binary is. Shared libraries allow software developers keep the size of their application storage and memory footprints down by using common code from a single location. So, you would issue a command line like LD_LIBRARY_PATH="/home/user/lib" ./program to run program and force it to use the experimental shared libraries in /home/user/lib in preference to any others on the

Static linking typically makes the resulting application faster and more portable, but increases the size (and thus the memory and storage footprint) of the binary. http://newmexicosupercomputer.com/php-error/php-error-while-loading-shared-libraries-libmysqlclient-so-15.html That is the reason for the version numbering system that I talked about above, and robust package management systems have helped ease shared library problems from the user's perspective, but they Listing 2 $ ls -l | grep libread lrwxrwxrwx 1 root root 18 2010-03-03 11:11 libreadline.so.5 -> libreadline.so.5.2 -rw-r--r-- 1 root root 217188 2009-08-24 19:10 libreadline.so.5.2 lrwxrwxrwx 1 root root 18 Major version number changes usually represent significant changes to the interface of the library, which are incompatible with previous versions.

I have a new guy joining the group. While I would argue that dependency chains are not really a "problem", they can work hardships on a system administrator. Better yet, you could add a "max-depth" option so that the user could specify how deeply into the dependency chain they wanted the script to check before moving on. http://newmexicosupercomputer.com/php-error/php-error-while-loading-shared-libraries-libcurl-so-4.html This is yet another way to work around library compatibility issues.

In Listing 13, I have created a wrapper script that could be used when developing new software, or as a last ditch effort to work around a really tough shared library Cheers! Probably you will have to insert the third one of your export statements near the start of this script.

There are some disadvantages to using them, but those disadvantages are typically considered to be outweighed by the benefits.

I've shown some of the command line options for ld-linux.so in Listing 4. Just because you've run the ldd command on an executable and satisfied all of it's top level dependencies doesn't mean that there aren't more dependencies lurking underneath. If there is a library that a large set of your programs rely on and it gets corrupted, deleted, over-written, etc, all of those programs are probably going to break. Another thing that you'll notice in Listing 2 is that there are links created from libreadline.so.5 to libreadline.so.5.2 and from libreadline.so.6 to libreadline.so.6.0.

I decide to experiment with the binaries under the pgAdmin3 directory, and so I use the cd command to move to /opt/PostgreSQL/8.4/pgAdmin3/bin. navigate here In this case both directories include the same required libraries.

Remember though that this wrapper script should not be used for a permanent solution to your shared library problems unless you have no other choice. postgres=# You can see that once I've set the LD_LIBRARY_PATH variable, all I have to do is enter my PostgreSQL password and I'm greeted with the psql command line interface. ln -s /usr/lib/libpq.so.4 /usr/lib/libpq.so.3 # php -v PHP 5.2.17 (cli) (built: Aug 4 2012 02:22:25) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies with the asked 1 year ago viewed 3586 times active 1 year ago Linked 3 Error while loading shared libraries: libpq.so.5: cannot open shared object file: No such file or directory Related 5Could

This technique can also help you work around incompatibilities in the naming conventions between what your system software expects, and what libraries are actually named. Official DirectAdmin, CloudLinux, LiteSpeed and Comodo partners. Listing 1 shows an example of an error you might see after installing PostgreSQL via a bin installer file.
