Building QODBC and QMYSQL
Hello everybody.
I need some help. I have been trying to do two things connected to QtSQL module.
I want to build QMYSQL and QODBC plugins to my open source 4.3.2 edition.
My OS is UBUNTU.
1) QMYSQL
I have downloaded development packages.
For mysql:
/usr/lib/ contains libmysqlclient.so
/usr/include/ contains mysql folder with:
errmsg.h my_getopt.h mysqld_ername.h ndb
keycache.h my_global.h mysqld_error.h raid.h
m_ctype.h my_list.h mysql_embed.h sql_common.h
m_string.h my_net.h mysql.h sql_state.h
my_alloc.h my_no_pthread.h mysql_time.h sslopt-case.h
my_config.h my_pthread.h mysql_version.h sslopt-longopts.h
my_dbug.h my_semaphore.h my_sys.h sslopt-vars.h
my_dir.h mysql_com.h my_xml.h typelib.h
inside
I strove to follow instructions below:
http://doc.trolltech.com/4.3/sql-dri...x-and-mac-os-x
Hence my input into bash was:
Quote:
mtr@mtr-laptop:/usr/local/Trolltech/Qt-4.3.2/plugins/sqldrivers/mysql$ sudo qmake -o Makefile "INCLUDEPATH+=/usr/include" "LIBS+=-L/usr/lib -lmysqlclient_r" mysql.pro
Error processing project file: /usr/local/Trolltech/Qt-4.3.2/plugins/sqldrivers/mysql/mysql.pro
mtr@mtr-laptop:/usr/local/Trolltech/Qt-4.3.2/plugins/sqldrivers/mysql$ sudo touch mysql.pro
mtr@mtr-laptop:/usr/local/Trolltech/Qt-4.3.2/plugins/sqldrivers/mysql$ sudo qmake -o Makefile "INCLUDEPATH+=/usr/include" "LIBS+=-L/usr/lib -lmysqlclient_r" mysql.pro

make: *** [mysql] Błąd 1
mtr@mtr-laptop:/usr/local/Trolltech/Qt-4.3.2/plugins/sqldrivers/mysql$
What is wrong?
2) ODBC
I have downloaded a package from unixODBC project website.
I have installed it in /usr/local/unixODBC-2.2.12 folder.
Then I followed or rather I tried to follow the instructions below:
http://doc.trolltech.com/4.3/sql-dri...x-and-mac-os-x
The
Quote:
sudo qmake "INCLUDEPATH+=/usr/local/unixODBC-2.2.12/include" "LIBS+=L/usr/local/unixODBC-2.2.12/lib -lodbc"
syntax of qmake is wrong as after typing it one receives manual for qmake.
I do not want to grope for a solution.
If anyone helps me with step-by-step instruction what to do I will be very grateful.
Mike

Seems you are mixing Qt3 into the issue here. Aren't you using qmake from Qt3 by any chance? What does qmake -v return?
As for odbc, you seem to be in an incorrect directory.
Re: Building QODBC and QMYSQL
I've seen it.
But look:
Quote:
mtr@mtr-laptop:~$ qmake -v
QMake version 2.01a
Using Qt version 4.3.2 in /usr/local/Trolltech/Qt-4.3.2/lib
There is one oddity more:
I ran ./configure -qt-sql-mysql. Then I made it and installed qt once again.
As an effect there emerged libqsqlodbc.so in plugins/sqldrivers/ folder.
I understand that it is because during installation qt found new repositories of odbc downloaded by me apart from unixODBC.
Still I do not have QMYSQL...
EDIT
Look:
Quote:
QSqlDatabase: available drivers: QMYSQL3 QMYSQL QSQLITE QODBC3 QODBC
I have tested QMYSQL and it works.
Thus I understand that everything is fine...
The funny thing is that although there is libqsqlodbc.so library in sqldrivers folder there is absolutely no trace of mysql library for qt.
