I have to run a tornado webapp on a server using psycopg2 with postgresql as backend. I am working on Red Hat Enterprise Linux Server release 6.5. I set up a virtual environment. Now, on this server, i don't have root access, i can't use pip or yum and i can't copy text from the server(so i can't post the exact error log). I have been manually downloading tar files for the libraries and installing them. When i try to run the webapp, i get the following error:
ImportError: /lib/libc.so.6: version `GLIBC_2.14' not found (required by /usr/lib/libpq.so.5)
The version for libc.so.6 is 2.12. The error is displayed in psycopg2/init.py.
I apologize as this is not much to go on, but the server has a lot of restrictions. Any help will be appreciated.
This error:
ImportError: /lib/libc.so.6: version `GLIBC_2.14' not found \
(required by /usr/lib/libpq.so.5)
means that libpq.so.5 was built on a system with GLIBC-2.14 or above.
Since you claim to not have root privilege on this system, and since /usr/lib is not writable by regular users, we must assume that you've asked the sysadmin on this system to install something for you, and the sysadmin installed a non-working PostgreSQL package.
There is no easy way you can fix this problem yourself.
You should work with your sysadmin to install correct packages for your system.
Alternatively, you can build install and use a newer version of GLIBC in non-default location. This is quite non-trivial. Some details here.

Debian Jessie, as well as sid, have a mercurial-git package which contains the hg-git plugin. However, this package was (auto-)removed from Debian Stretch to to a release-critical bug.
But - I need it installed and running. Surely this should be possible, right?
Well, I followed the installation instructions on the plugin page:
I ran apt-get install python-setuptools python-setuptools-git python4-setuptools python3-setuptools-git
I ran easy_install hg-git and it seemed to work
But still, when I run various mercurial operations I get, as the first line, the error message:
*** failed to import extension hgext.git: No module named git
(regardless of whether I'm doing anything git-related or not.)
My questions:
Why is this happening?
What do I need to do in order to make the error message go away while having hggit working?
Now,
How do I correctly install dulwich to get hg-git working on Windows?
Apparently, that critical bug doesn't manifest always (and perhaps only under very specific circumstances), so you can try installing the Debian sid version of the mercurial-git package (that is, version 0.8.11-1 at the time of writing). There's a SuperUser question about how to do this:
https://linuxaria.com/howto/how-to-install-a-single-package-from-debian-sid-or-debian-testing
my personal opinion in this case is to simply install the .deb file, which you can get from here (it's not platform-specific; at the link you'll need to choose a mirror.) That makes the error message go away, at least assuming you have:
[extensions]
hgext.bookmarks =
hggit =
in your ~/.hgrc file.
I am getting a bunch of compile errors when I try to install the MySQL DBD::mysql Perl library. I am trying to install this library on OpenSuse linux (SUSE Linux Enterprise server 10 (x86_64) version 10, patch level 4)
The install fails when trying to compile dbdimp.h. There are hundreds of complile errors but I have reason to believe they all stem from the first 3:
dbdimp.h:23:49: error: mysql.h: No such file or directory
dbdimp.h:24:45: error: mysqld_error.h: No such file or directory
dbdimp.h:26:49: error: errmsg.h: No such file or directory
I believe that the reason I am getting the errors above is that I have no MySql Client installed. I do not know how to install mysql client (I believe I am supposed to get some version of libmysqlclient).
I am brand new to opensuse and vaguely familar with installing packages on Linux in general have used yum, yast, apt-get on ubuntu + centOS previously but the only package manager tools that seem to be on OpenSuse 10 are rpm and zypper. I have not managed to install the required mysql client using either of these. If anyone knows how to install MySql Client to resolve my issue I would greatly appreciate any recomendations
Thanks
You need to install MySQL or the MySQL client libraries, either through your system's package manager or by following the installation instructions from the source code.
It sounds like your question is really "How do I install MySQL on OpenSuse", which would be more appropriate for one of the other StackExchange sites.
I was able to resolve this to a point. In my original question, I stated that I had tried using YAST but that it had not worked. In fact, I did not fully explore the YAST install option but when I did, I managed to download install the required librarys by following an article I found (http://adminramble.com/install-mysql-yast/#chitika_close_button)
I was able to open the YAST GUI in the terminal window (not an X-window display) and navigate through the "software management" section wherein I was able to do a search for MySql. Amoung the search results were mysql client libraries, which I then selected and hit "Accept". The installation started and completed successully.
In order to complile the PERL DBD::mysql module, I had to create a new makefile with the ccflags specified so that the header files could be found:
perl Makefile.PL --cflags -I/usr/include/mysql
I say "to a point" at the top of this comment because I then ran into further problems compiling but my original issue posted has been partially resolved and getting this far may help someone else who is experiencing the same problem. Will update if I get a solution to the compile problem.
Running on MAC os 10.6.8
with postgresSQL installed, as well django - using python2.7
Also installed psycopg2 and dj-database-url using pip in my virtual env
And added these two lines to my setting.py:
import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}
Based on instructions for Heroku in:
https://devcenter.heroku.com/articles/django#database_settings
When running:
python manage.py runserver
I am getting this error:
ImportError: dlopen(/Users.... venv/lib/python2.7/site-packages/psycopg2/_psycopg.so, 2): Symbol not found: _PQbackendPID
Referenced from: /Users.... venv/lib/python2.7/site-packages/psycopg2/_psycopg.so
Expected in: dynamic lookup
I kept searching for hours and tried all kind of thing including the advice on:
Mac OS X Lion Psycopg2: Symbol not found: _PQbackendPID
to no avail.
Wonder if anyone had such an issue and had any luck.
I had the same problem. Instead of installing the dependencies as Heroku suggests using
pip install Django psycopg2 dj-database-url
clone whatever repo you're hoping to run in venv, keeping its original settings.py. Then:
source venv/bin/activate
to activate the new environment, cd into your new repo, and python manage.py runserver. Should be set.
Alternatively, you could remake PostGreSQL, and run again, but that's a bit more of a task - it would work for psycopg2, though. As far as I can tell that issue comes from using an 64 or i386 build when you should be using a 32 build - but I'm not sure about this, and the above solution works well to solve the problem and use venv for what you're actually going to be using it for, most likely.
I had the same problem as you guys and I had read many pages and I couldn't find the answer in any of them. Many solution was about installing from source file and don't relate to the virtual environment.
I've found and tested following solution and it solve my problem.
1- Make sure your Postgres is NOT higher than 9.4 version according to psycopg2. Check python version as well. I use Postgres 3.9.9.
2- The problem is behind different version of Python(32/64 bit). It should comply with your operation system's bit architecture which is 64bit. Uninstall all versions of Python and pip from your system. Instruction you can find here but do NOT remove Python2.7 which is Apple-supplied system Python.
3- Install "Mac OS X 64-bit/32-bit" installer from python official website and install it.
After that install pip. Note that you should use the command "python3.5" for using Python version 3.5. You might install virtualenv from the new pip as well.
4- After all that you can go on your virtualenv and type "pip3 install -r requirement.txt" for installing all dependencies on your local machine.
Hope this can help you.
I am trying to install the contrib/unaccent package for Postgresql 8.4 on my Ubuntu box. But I got the error message when I typed make:
/usr/lib/postgresql/8.4/lib/pgxs/src/makefiles/pgxs.mk: No such file or directory
Apparently PGXS is Postgresql's infrastructure for installing extensions, but I could not find the file pgxs.mk at all on my ubuntu box.
Following some leads on the Internet, I tried installing libpq-dev. Nonetheless, I couldn't find any pgxs.mk even after installing libpq-dev.
What's really frustrating is that I can't even find an example of pgxs.mk anywhere on the Internet. How do I install the PGXS infrastructure?
Probably you need to install postgresql-server-dev-8.4 package, which contains your missing makefile:
/usr/lib/postgresql/8.4/lib/pgxs/src/makefiles/pgxs.mk
I have installed Eclipse 3.5.2 and the plugin Subversion JavaHL Native Library Adapter 1.6.9.2 and this worked without any problems. However, this morning I was forced to change the password to logon to my Mac and since then I get the message that "Subversion native library not available" when I try to save any changes. Can anyone help? I have tried to add this line (-Djava.library.path=/usr/lib/jni) to the eclipse.ini file but this didn´t seem to make any difference.
Can anyone help?
Install MacPorts or HomeBrew, then run the following command:
For MacPorts, the commands to run are:
sudo port install subversion-javahlbindings +no_bdb +universal
For HomeBrew, the command is:
brew install --universal --java subversion
I was having a similar problem on Mac OS X Snow Leopard. I suspect your libraries are there but just need permissions changed, whereas I didn't have the libs at all.
The directory to check is /opt/subversion/lib, see if it has any libsvnjavahl files. In your case they may be there and just need new permissions.
To get the files I followed the the instructions they give for installing JavaHL on OS X, which is to download and install Open CollabNet. (login required, although it's free)
Then you just need to update your environment variable in .profile, something like:
export PATH=.:/opt/subversion/bin:$HOME/bin:$PATH
Then ran:
. .profile
Then I tested with javahltests.jar as mentioned here.
The easiest thing to do is download and install the OSX package that is provided on openCollabNet.
MacPorts also provides an easy Subversion and JavaHL package, however on Snow Leopard ?MacPorts is still compiling these packages as simple 32-bit binaries. If you use the default Snow Leopard JVM which is 64-bit you will get an error...
Failed to load JavaHL Library.
These are the errors that were encountered:
no libsvnjavahl-1 in java.library.path
no svnjavahl-1 in java.library.path
/opt/local/lib/libsvnjavahl-1.0.0.0.dylib: no suitable image found. Did find: /opt/local/lib/libsvnjavahl-1.0.0.0.dylib: mach-o, but wrong architecture
Note the error about wrong architecture. This is because the 64-bit JVM cannot load a 32-bit native library. The ?CollabNet binaries for OSX do not have this problem because they include both 32-bit and 64-bit versions.

Here is a blog entry that gives a solution:

I don't know whether this will work in your particular situation, but it's worth a try.
(Edited to fix link that became broken after I posted. The link became broken sometime between May 3 and June 1.)
In case you already have subversion installed I'd recommend performing first a brew uninstall and then the install again. And follow the steps to create the links indicated after the install concludes. This worked for me. Regards
I fixed it installing the SVNKit Client Adapter (not required) package.
