I am running the PECL PHP-Memcached 3.2.0 on PHP 7.x and PHP 8.1.0 Windows servers without problem.
Unfortunately, it's impossible to make it work under PHP 8.1.7.
Unable to load dynamic library - The specified module could not be found
I obviously specify that the DLL extension is in the right directory, and that it is of course the x64 TS VS16 version.
Solution:
The two dependencies DLLs (libmemcached.dll and libhashkit.dll) must be copied under c:\windows or in any directory belonging to the %PATH%
Restart your webserver service.

I have some trouble when I want to add a database.
_dataBase = QSqlDatabase::addDatabase("QPSQL");
After calling this method I have an error:
QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
I include to PATH variable paths to:
PostgreSQL\9.3\bin
PostgreSQL\9.3\lib
PostgreSQL\9.3\include
Also I copy folder sqldrivers to Debug folder. Also tried to copy dlls drom this folder to Debug. Doesn't work either.
I came here googling because I had the same problem in Windows.
In my case to solve the issue I had to install PostgreSQL for Windows 32 bits since my Qt target was MinGW 32 bits.
Additionally, I had to add the PATH to the PostgreSQL bin and lib directories so Qt could find the right .dlls.
#SET PATH=C:\Program Files (x86)\PostgreSQL\9.6\bin\;C:\Program Files (x86)\PostgreSQL\9.6\lib\;%PATH%
The PATH can be set before launching Qt Creator or using the Qt Creator itself via the Build Environment in the Projects pane.
Add the system variable QT_DEBUG_PLUGINS=1 if you want to get full information of why the QPSQL driver has not been loaded.
Probably you will discover that Qt is not able to find it. Copy and paste the output here to know what exactly happens.
Use depends.exe on qsqlpsql.dll and found that this dll need libpq.dll from PostgreSQL\9.3\libfolder. Add libpq.dll to Debug folder and it works:)
Try pip install PyQt5 event if you already installed it using conda or installer. It helped me.
I got same problem with deploying Qt application (windeployqt didn't help). I had to copy more .dlls (libcrypto-1_1-x64.dll, libiconv-2.dll, libintl-8.dll, libpq.dll, libssl-1_1-x64.dll, libwinpthread-1.dll) from postgreSQL bin path (c:\Program Files\PostgreSQL\12\bin) next to .exe file (according to dependency walker).
I'm trying to create my first application with Lazarus Pascal and PostgreSQL.
The pg database is on my Ubuntu Linux host. Lazarus is on XP, running through VirtualBox.
When trying to make a connection to the PG database, I get an error that libpq.dll is missing.
What should I do? Pretty new to this platform.
From the docs here http://wiki.lazarus.freepascal.org/postgres
Error: "Can not load PostgreSQL client library "libpq.dll""
The program cannot find your PostgreSQL driver files. Copy all required PostgreSQL .dll/.manifest files either
to your project directory and your executable output directory,
or to a directory in your search path (e.g. c:\windows\system32)
A good example that demonstrates how to include drive DLL files when connecting Lazarus with PostgreSQL under Windows is easyDB.
On Linux/Unix/OSX: make sure the PostgreSQL libraries are in your library search path, e.g.:
On linux add the path to the libpq.so file to the libraries section in your /etc/fpc.cfg file. For example : -Fl/usr/local/pgsql/lib
It may be necessary to create a symbolic link from a specific library version to a general library name:
ln -s /usr/lib/pqsql.so.5 /usr/lib/pqsql.so
. Alternatively, install the postgresql client -dev package using your distribution's package manager
I'm attempting to install memcache for MAMP. It seems to configure/make/install fine but I'm getting an error saying the API version is wrong:
[26-Oct-2012 17:40:51 UTC] PHP Warning: PHP Startup: memcache: Unable to initialize module
Module compiled with module API=20090626
PHP compiled with module API=20100525
These options need to match
in Unknown on line 0
I am using MAMP 2.1.1 on OS X Mountain Lion.
I'm using this memcache build:
http://pecl.php.net/package/memcache/2.2.7
I extracted the archive into this directory:
/Applications/MAMP/bin/php/php5.4.4/include/memcache-2.2.7
And then ran these commands from the extracted directory:
/Applications/MAMP/bin/php/php5.4.4/bin/phpize
./configure
make
sudo make install
No errors except what I noted above, which I am seeing in:
/Applications/MAMP/logs/php_error.log
Any ideas on how to fix this?
Ok so after a few hours of trying to figure this out, I was able to find the problem and fix it. I'm pretty much a huge noob when it comes to all of this stuff, but here is the best I can explain what I think I figured out:
So, when I ran first ran phpize on the module, it was configured for my system's default installation of php. I had to point php and phpize to my PATH in my .bash_profile
export PATH=/Applications/MAMP/Library/bin:/Applications/MAMP/bin/php/php5.4.3/bin:/usr/local/bin:$PATH:/opt/local/bin
Make sure to change the php version to what ever version you are running.
After adding this to your path, running phpize -v should return:
PHP Api Version: 20100412
Zend Module Api No: 20100525
Zend Extension Api No: 220100525
and running which phpize should return: /Applications/MAMP/bin/php/php5.4.3/bin/phpize
So then it was just a matter of deleting all of the files that were installed the first time, and running through the installation process again. I unzipped the downloaded file cd into the unzipped folder and ran:
/Applications/MAMP/bin/php/php5.4.3/bin/phpize
./configure
make
cp modules/memcache.so /Applications/MAMP/bin/php/php5.4.3/lib/php/extensions/no-debug-non-zts-20100525/
And boom done. It works!
This article helped me out a lot, even though it isn't related to memcache: http://drupal.org/node/1464236
I have a fresh install of Plone on a CentOS 5.6 server. I used the Unified Insatller and used ZEO ... I can't seem to find my "zinstance" folder. when I do a 'locate zinstance' it gives me the zinstance.sh within the installer it's self, no where else. . Any ideas?
If you installed with ZEO there will be no "zinstance" folder. Instead you'll find a "zeoserver" folder, and a "bin" folder with a bunch of scripts.
On linux the unified installer install to /usr/local/plone by default I believe.
I want to write application which uses Postgresql as DBMS.
To write client application do I need libpq library and header files?
If yes where I would get libpq library and header files.
Libpq is included in the full PostgreSQL source code. You can use just libpq without the rest of PostgreSQL, but must download the full package.
You can download it from the PostgreSQL Downloads page.
Once you extract the full package it is inside src\interfaces\libpq.
The PostgreSQL installation guide details how to install only the client libraries in the Installation section, under Client-only installation.
Libpq documentation is also available.
In postgresql sources, src\interfaces\libpq.
And yes, it is possible to compile only the libpq.
get the lipq from repo, {for debian} :
sudo apt-get install libpq-dev
I was also facing this issue but didn't got a clear answer:
This issue clearly states that while installing diesel-cli system is not able to locate libpq.lib
First of all you should have a Postgres installed on your machine.
Also diesel require visual c++, thus download and install it if not already, the size of setup will be ~5gb.
Once above installations are done you need to setup environment variables:
In my case path of Postgres installation is C:\Program Files\PostgreSQL thus add 2 environment variable path under User variables add new in Path where your libpq.lib is located in my case it is available in both C:\Program Files\PostgreSQL\12\lib and C:\Program Files\PostgreSQL\12\bin
Once this is added create one more environment variable PQ_LIB_DIR and set path as shown below
Note: Once done re-trigger the installation command in a new cmd window
Source: pq-sys and github-solution
For Windows users, it's in (version may be different)
C:\Program Files\PostgreSQL\11\lib
There you find libpq.lib. Provide this directory to Linker input.
Don't forget to include C:\Program Files\PostgreSQL\11\include directory for include directories.
I fix this problem reccently. This is a solution if you don't want to install Postgres in you windows.
At first, you need download Postgres Binaries. The version I download is 13.6, but it's seems like any version is fine.
Unzip the zip file.Copy libpq.lib from pgsql\lib to shomewhere like C:\Program Files\Postgres\lib.
Execute the following command in cmd window.
setx PQ_LIB_DIR "{where_you_copy_to}"
Open a new cmd windows and install diesel_cli
cargo install diesel_cli --no-default-features --features postgres
In linux vertify you get the libpq.
1st, there is an app: pg_config: https://www.postgresql.org/docs/current/app-pgconfig.html
after you found out the pg_config absolute bin path.(if you installed multi version of postgressql) Then You can get
--includedir
Print the location of C header files of the client interfaces.
--libdir
Print the location of object code libraries.
Then try to compile/build some example code: https://www.postgresql.org/docs/current/libpq-example.html
Some common failure example: https://www.postgresql.org/docs/current/libpq-build.html
You can install Postgres locally from https://www.enterprisedb.com/downloads/postgres-postgresql-downloads but select only "Command line tools" for install.
After that, you can found libpq.dll in C:\Program Files\PostgreSQL\15\bin
