Set-up MariaDB library file location programmatically?

@SPlatten
It is actually in the doc:

If something goes wrong and you want qmake to recheck your available drivers, you must remove config.cache in <QTDIR>/qtbase/src/plugins/sqldrivers - otherwise qmake will not search for the available drivers again.

I think the doc should make that sentence more sight-catching.
Many people who had their first qmake command unsuccessful would be stucked there, with a never-changing config.log.

@Bonnie , Hello, I'm trying to rebuild the library again and from my notes:

$QTDIRBIN/qmake -- MYSQL_INCDIR="/usr/local/Cellar/mariadb/10.4.13/include/mysql" "MYSQL_LIBDIR=/usr/local/Cellar/mariadb/10.4.13/lib" MYSQL_LIBS="-lmariadb"

This results in:

Usage: /Users/sy/Qt/5.15.1/clang_64/bin/qmake [mode] [options] [files]

QMake has two modes, one mode for generating project files based on
some heuristics, and the other for generating makefiles. Normally you
shouldn't need to specify a mode, as makefile generation is the default
mode for qmake, but you may use this to test qmake on an existing project

Mode:
  -project       Put qmake into project file generation mode
                 In this mode qmake interprets [files] as files to
                 be added to the .pro file. By default, all files with
                 known source extensions are added.
                 Note: The created .pro file probably will 
                 need to be edited. For example add the QT variable to 
                 specify what modules are required.
  -makefile      Put qmake into makefile generation mode (default)
                 In this mode qmake interprets files as project files to
                 be processed, if skipped qmake will try to find a project
                 file in your current working directory

Warnings Options:
  -Wnone         Turn off all warnings; specific ones may be re-enabled by
                 later -W options
  -Wall          Turn on all warnings
  -Wparser       Turn on parser warnings
  -Wlogic        Turn on logic warnings (on by default)
  -Wdeprecated   Turn on deprecation warnings (on by default)

Options:
   * You can place any variable assignment in options and it will be *
   * processed as if it was in [files]. These assignments will be    *
   * processed before [files] by default.                            *
  -o file        Write output to file
  -d             Increase debug level
  -t templ       Overrides TEMPLATE as templ
  -tp prefix     Overrides TEMPLATE so that prefix is prefixed into the value
  -help          This help
  -v             Version information
  -early         All subsequent variable assignments will be
                 parsed right before default_pre.prf
  -before        All subsequent variable assignments will be
                 parsed right before [files] (the default)
  -after         All subsequent variable assignments will be
                 parsed after [files]
  -late          All subsequent variable assignments will be
                 parsed right after default_post.prf
  -norecursive   Don't do a recursive search
  -recursive     Do a recursive search
  -set <prop> <value> Set persistent property
  -unset <prop>  Unset persistent property
  -query <prop>  Query persistent property. Show all if <prop> is empty.
  -qtconf file   Use file instead of looking for qt.conf
  -cache file    Use file as cache           [makefile mode only]
  -spec spec     Use spec as QMAKESPEC       [makefile mode only]
  -nocache       Don't use a cache file      [makefile mode only]
  -nodepend      Don't generate dependencies [makefile mode only]
  -nomoc         Don't generate moc targets  [makefile mode only]
  -nopwd         Don't look for files in pwd [project mode only]

I've checked $QTDIRBIN, which contains:

QTDIRBIN=/Users/sy/Qt/5.15.1/clang_64/bin

MariaDB is installed in:

/usr/local/Cellar/mariadb/10.5.7

Can you help?

jsulm

@SPlatten In which directory do you call qmake?

SPlatten

@jsulm, the path of make is specified by the QTDIRBIN environment variable and I've checked the qmake application is in that location.

jsulm

@SPlatten said in Set-up MariaDB library file location programmatically?:

That is not what I asked.
In which directory are you when you call qmake?

SPlatten

@jsulm , Ok, thank you, that was part of the problem. I am in:

/Users/sy/Qt/5.15.1/Src/qtbase/src/plugins/sqldrivers

The output now is:

Running configuration tests...
Checking for DB2 (IBM)... no
Checking for InterBase... no
Checking for MySQL... no
Checking for OCI (Oracle)... no
Checking for ODBC... no
Checking for PostgreSQL... no
Checking for SQLite (version 2)... no
Checking for TDS (Sybase)... no
Done running configuration tests.

Configure summary:

Qt Sql Drivers:
  DB2 (IBM) .............................. no
  InterBase .............................. no
  MySql .................................. no
  OCI (Oracle) ........................... no
  ODBC ................................... no
  PostgreSQL ............................. no
  SQLite2 ................................ no
  SQLite ................................. yes
    Using system provided SQLite ......... no
  TDS (Sybase) ........................... no

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/Users/sy/Qt/5.15.1/clang_64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

How do I get MySql set to yes ?

I've removed config.cache and re-run qmake, still the same results.

jsulm

@SPlatten said in Set-up MariaDB library file location programmatically?:

As always in such a situation: check config.log for failed MySQL test and see what exactly the problem was...

SPlatten

@jsulm

> main.cpp:2:10: fatal error: 'sybfront.h' file not found
> #include <sybfront.h>
>          ^~~~~~~~~~~~
> 1 error generated.
> make: *** [main.o] Error 1

Not sure why this is an issue, I have built the driver for a previous version.

jsulm

@SPlatten said in Set-up MariaDB library file location programmatically?:

sybfront.h

Google says that header file is part of freetds-dev package (on Ubuntu).

SPlatten

@jsulm , I'll see what I can find.

After some googling:

brew upgrade freetds

Still getting same result tho.

SPlatten

Can anyone offer a solution?

SGaist

Since you want to build the MariaDB backend, what does the checks related to that backend say ?

SPlatten

@SGaist , can you explain what you mean please? This is the content of the config.log:

I've no idea why there is mention of win32, I'm on an iMAC running:

macOS Big Sur

SGaist

If you take the time to read what you just posted, you'll see that it's for the Db2 database.

The logs contain all the tests that are done, concentrate on the one that are pertinent to MariaDB.

SPlatten

@SGaist , that's the problem isn't it? MySQL isn't mentioned.

SGaist

Did you grep through the complete logs ?
Until now you extracted information for two unrelated database backend.

SPlatten

@SGaist , sorry, I'm am idiot:

Which file do I edit to apply?

CONFIG+=sdk_no_version_check

SGaist

This is the real error:

@SPlatten said in Set-up MariaDB library file location programmatically?:

Undefined symbols for architecture x86_64:

"_mysql_get_client_version"

SPlatten

@SGaist , After seeing the output and its recommendation I edited sqldrivers.pro and added:

TEMPLATE = subdirs
  
sqldrivers_standalone {
    _QMAKE_CACHE_ = $$shadowed($$SQLDRV_SRC_TREE)/.qmake.conf
    load(qt_configure)
}

qtConfig(sql-psql)     : SUBDIRS += psql
qtConfig(sql-mysql)    : SUBDIRS += mysql
qtConfig(sql-odbc)     : SUBDIRS += odbc
qtConfig(sql-tds)      : SUBDIRS += tds
qtConfig(sql-oci)      : SUBDIRS += oci
qtConfig(sql-db2)      : SUBDIRS += db2
qtConfig(sql-sqlite)   : SUBDIRS += sqlite
qtConfig(sql-sqlite2)  : SUBDIRS += sqlite2
qtConfig(sql-ibase)    : SUBDIRS += ibase

CONFIG+=sdk_no_version_check

I then removed all the config files including the cache with:

rm -R config.*

Then executed:

$QTDIRBIN/qmake -- MYSQL_INCDIR="/usr/local/Cellar/mariadb/10.5.7/include/mysql" "MYSQL_LIBDIR=/usr/local/Cellar/mariadb/10.5.7/lib" MYSQL_LIBS="-lmariadb"

All this as in:

/Users/sy/Qt/5.15.1/Src/qtbase/src/plugins/sqldrivers

The result was config.log:

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/Users/sy/Qt/5.15.1/clang_64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

I then executed make:

cd sqlite/ && ( test -e Makefile || /Users/sy/Qt/5.15.1/clang_64/bin/qmake -o Makefile /Users/sy/Qt/5.15.1/Src/qtbase/src/plugins/sqldrivers/sqlite/sqlite.pro ) && /Applications/Xcode.app/Contents/Developer/usr/bin/make -f Makefile 
make[1]: Nothing to be done for `first'.

Then make install:

cd sqlite/ && ( test -e Makefile || /Users/sy/Qt/5.15.1/clang_64/bin/qmake -o Makefile /Users/sy/Qt/5.15.1/Src/qtbase/src/plugins/sqldrivers/sqlite/sqlite.pro ) && /Applications/Xcode.app/Contents/Developer/usr/bin/make -f Makefile install
/Users/sy/Qt/5.15.1/clang_64/bin/qmake -install qinstall -exe ../plugins/sqldrivers/libqsqlite.dylib /Users/sy/Qt/5.15.1/clang_64/plugins/sqldrivers/libqsqlite.dylib
/Users/sy/Qt/5.15.1/clang_64/bin/qmake -install qinstall /Users/sy/Qt/5.15.1/Src/qtbase/src/plugins/sqldrivers/plugins/sqldrivers/libqsqlite.dylib.dSYM/Contents/Info.plist /Users/sy/Qt/5.15.1/clang_64/plugins/sqldrivers/libqsqlite.dylib.dSYM/Contents/Info.plist

/Users/sy/Qt/5.15.1/clang_64/bin/qmake -install qinstall /Users/sy/Qt/5.15.1/Src/qtbase/src/plugins/sqldrivers/lib/cmake/Qt5Sql/Qt5Sql_QSQLiteDriverPlugin.cmake /Users/sy/Qt/5.15.1/clang_64/lib/cmake/Qt5Sql/Qt5Sql_QSQLiteDriverPlugin.cmake

I've also tried to mysql.pro:

CONFIG+=sdk_no_version_check
  
TARGET = qsqlmysql

HEADERS += $$PWD/qsql_mysql_p.h
SOURCES += $$PWD/qsql_mysql.cpp $$PWD/main.cpp

QMAKE_USE += mysql

OTHER_FILES += mysql.json

PLUGIN_CLASS_NAME = QMYSQLDriverPlugin
include(../qsqldriverbase.pri)

Then repeated the above steps, still mysql shows no??? and same results. Is it looking for a mysql library because MariaDB mostly uses the name mysql as it is based on that but I've notice that there are a few folders where the name is actually mairadb and not mysql?

SGaist

Serious question: do you realise that you just silenced a warning unrelated to the actual error ?

I already pointed you to the real issue: a symbol is missing: _mysql_get_client_version.

In any case, Qt 5.15.2, MariaDB 10.5.8 is a working combo using the same qmake line you have with just the versions updated.
