I'm trying to write a c++ wrapper for MySQL:
cannot open input file 'libmysql.lib'
I did install mySQL server but I still don't have libmysql.lib
Follow these instructions (I am assuming you installed an instance of MySQL Server):
link your project with libmysql.lib
Ignore the message error "Missing libmysql.dll"
copy libmysql.dll to the release folder
Compile and run your program.

I am trying to install the MySQL server and Connector/C++ through Installshield (Installscript) by executing MySQLInstallerConsole.exe with following argument,
"community install server;5.6.21;x64:*:port=3306;openfirewall=true;passwd=root, c++;1.1.4;x64 -silent"
MySQL Installation fail
It just runs through the install process without any problem however, nothing is installed and the log file gives following error for each install package:
mysql-installer Information: 10 : MySQL Server 5.6.21's change state request failed.
mysql-installer Information: 10 : Connector/C++ 1.1.4's change state request failed.
When I use the above argument through command prompt manually, it works fine,
MySQL Installation success
Anyone know, how to solve this issue.
My project can't finish build process because I constantly have this error during Visual Studio build: Cannot open include file: 'msoledbsql.h': No such file or directory
I have 'msoledbsql.h' file included in one of the header files.
Does anyone know the solution of this issue?
After a long research of this issue I found that I've missing msoledbsql.h file on my machine.
The solution for this is to install Microsoft OLE DB Driver for SQL Server. We can find the driver on official Microsoft site Microsoft OLD DB Driver for SQL Server and choose the one suitable for your system architecture (x64 or x86).
Very important thing during the installation process is to select both options
OLE DB Driver 19 for SQL Server
OLE DB Driver 19 for SQL Server SDK
That should solve the issue.
i have problems connecting to an Oracle Database, i´ve configured the connection but it says:
Error connecting to database [_____] :org.pentaho.di.core.exception.KettleDatabaseException:

I´ve downloaded the driver but i don´t know where to put it. I can´t find any lib-ext folder.
Any ideas?
Put your driver into de data-integration/lib folder.
put this driver in lib folder you can find the path of lib folder as data-integration/lib
I want to deploy my project to VPS Centos7. But i am getting error while installing postgres. When i type
create extension postgis;
Getting error
ERROR: could not open extension control file
"/usr/pgsql-9.6/share/extension/postgis.control": No such file or
directory
Because postgis.contol is located in another place,
find /usr -name postgis.control
/usr/share/pgsql/extension/postgis.control
But postgres trying to create it from /usr/pgsql-9.6/share/extension/postgis.control
This question already was asked before, but my problem is other.
For me, I run below command in Ubuntu, and the issue was resolved.
sudo apt install postgresql-10-postgis-scripts
then run
CREATE EXTENSION postgis
It works fine for me.I hope it helps.
I'm a newbie at c++ linking and databases, so may be i'm asking a really stupid question. Anyway, i'm trying to access to firebird database using Qt5 for Windows. I've checked google and found 2 ways of doing so:
build ibase driver from Qt source;
use firebird through ODBC driver.
Software versions
I'm using latest version of Qt: 5.1.1. Firebird 2.5 is working ok: i've create a test_base and test user admin. Administartion of test_base i've done through FlameRobin.
Building
I've downloaded qt5.1.1 source and unpacked it in c:/devtools/qt5.1.1-src. Since Qt4.7-4.8 folder and project structure has been changed so old FAQs cannot be applied here. So i tried to build sql.pro from qtbase\src\sql folder with 2 lines added:
INCLUDEPATH+= C:/devtools/firebird/firebird_2_5/include
LIBS+= C:/devtools/firebird/firebird_2_5/lib/fbclient_ms.lib
And i've added C:/devtools/firebird/firebird_2_5/lib/ and C:/devtools/firebird/firebird_2_5/include in system PATH. Compilation is done without any error and i get a qt_pch.h.gch\c++ file in build dir. And i have no idea what's to do next, because i hoped to have bunch of .a and .dll files or bunch of error at least.
Using ODBC driver
I've downloaded and installed firebird ODBC driver from here. Installation was successful and i created ODBC DSN source mydb in Windows ODBC manager. Test connection button from ODBC configurator says that everything is ok.
Next thing i did was opening SQL Browser example from Qt Creator. And it fails to open my ODBC base with following parameters:
Driver: QODBC
Database Name: mydb
Username: admin
Password: admin
Hostname: localhost
Port: Default
And i get an error message: "[ODBC Firebird Driver] Unable to connect to data source: library 'C:\devtools\Firebird\Firebird_2_5\bin\fbclient.dll' failed to load QODBC3: Unable to connect".
I'm looking for resolving any of this two issues. Thanks in advance.
upd: i've connected firebird database through ODBC: the error was in using x64 database with x86 QODBC. Nota bene: in order to manage x86 DSN ODBC in x64 Windows 7 one must run ODBC manager from %WINDIR%\SysWOW64\odbcad32.exe NOT from Administration Panel as it explained here.
But what about building ibase from qt source?
