Building QMYSQL Plugin with nmake for msvc2017: module machine type 'x86' conflicts with target machine type 'x64'

obradley

Hi,

I've been trying to build the qsqlmysql.dll for Qt5.14.2 for msvc2017. This was quite problematic, and I've encountered the same issues that a lot of people have previously had, but now I've run into a unique issue that no one on here seems to have asked about before, and a google search doesn't seem to be revealing any answers; an nmake error "module machine type 'x86' conflicts with target machine type 'x64'". This error is occurring when I run nmake install inside sqldrivers\mysql:> when trying to build the plugin.

So far I've done the following in terms of building the plugin:

Launched x64 Native Tools Command Prompt for VS2017, cd'd into C:\Qt\Qt5.14.2\5.14.2\Src\qtbase\src\plugins\sqldrivers and checked that qmake works by running "qmake -version".

Run "qmake -- MYSQL_INCDIR="C:/Program Files/MySQL/MySQL Connector C 6.1.3/include" MYSQL_LIBDIR="C:/Program Files/MySQL/MySQL Connector C 6.1.3/lib""
Which gives an output of:

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

 [...]

Cd'd into C:\Qt\Qt5.14.2\5.14.2\Src\qtbase\src\plugins\sqldrivers\mysql and run "nmake install" which ends with the following output:

Qt5Sql.lib(Qt5Sql.dll) : fatal error LNK1112: module machine type 'x86' conflicts with target machine type 'x64'
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual 
Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX64\x64\link.EXE"' : return code '0x458'
Stop.
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual 
Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX64\x64\nmake.exe"' : return code '0x2'
Stop.

I then tried running the command in "3." in x86 Native Tools Command Prompt for VS2017 and in x64_x86 Cross Tools Command Prompt for VS2017, and the same error returns each time. Googling the issue only seems to bring back results specific to certain programs, etc.

Any help would be greatly appreciated.

qmake

Which qmake are you calling here? Use absolute path to qmake from Qt installation you want to build for. Make sure both, MySql libs and Qt, are both same architecture.

obradley

Hi, running "qmake -version" in the x64 vs 2017 command prompt from the C:\Qt\Qt5.14.2\5.14.2\Src\qtbase\src\plugins\sqldrivers\mysql directory returns:

    QMake version 3.1
    Using Qt version 5.14.2 in C:/Qt/Qt5.14.2/5.14.2/msvc2017/lib

This is the build I'm trying to make the plugin for.

jsulm

@obradley It looks like you MySQL libs are x86, but you're building for x86_64. Make sure you have x86_64 MySQL client libs build.

obradley

According to MySQL installer the version of the MySql Connector/C that I have is for a x64 architecture. The version of Qt that I downloaded is for a x86 architecture. Is there some way I can build for x86?

jsulm

@obradley Do you really want/need to use x86 Qt build? If not simply install x86_64 Qt version.
QtCompany does not provide recent Qt versions as x86 builds as far as I know, so if you would need a recent Qt version you would need to build it by yourself.

x86_64 Qt

I am using Qt version 5.14.2. As far as I can see from the page http://download.qt.io/archive/qt/5.14/5.14.2/ the only version available for Windows is for x86, at least for the installer. Should I change to a more recent version?

If not simply install x86_64 Qt version.

Update: I just ran qtdiag in the command prompt and it returned the following:

which seems to suggest that I am already using the x86_64 build. Is this not compatible with the x64 build I have for the MySQL C connector?

jsulm

@obradley QtCreator does not matter at all here. What matters is Qt.

Try to start from a clean source tree (without any build artefacts from your previous builds) with "x86 Native Tools Command Prompt for VS2017 and in x64_x86 Cross Tools Command Prompt".

obradley

In order to be sure that there's no lingering dependency issues and a clean build environment I've uninstalled and re-installed both MySQL and Qt. My current SQL server version is 5.6.19 for an x64 architecture, and the C connector is 6.1.3 for x64. I'm reinstalling Qt 5.14.2 for x86_64. I'm then going to rerun the qmake process in x64_x86 Cross Tools Command Prompt. Is that correct?

Cross Tools Command Prompt

Not sure what you mean by "Cross Command"? Do you mean the Visual Studio command prompt? If so, then yes, that's what you should do.

x64_x86 Cross Tools Command Prompt for VS2017

Ok I've reinstalled both MySQL and Qt and have just repeated steps 1 and 2 in my original question but now inside x64_x86 Cross Tools Command Prompt for VS2017 only for the output to be:

Running configuration tests...

[...]

Should I try a different VS command prompt since it worked in x64 Native Tools Command Prompt for VS2017, or will that just cause the issue to repeat itself?

jsulm

@obradley What does the config.log file says now?

C:\Program Files\MySQL\MySQL Connector C 6.1.3\lib\libmysql.lib : warning LNK4272: library machine type 'x64' conflicts with target machine type 'x86'

You're still mixing x86 and x86_64. I think C:\Program Files\MySQL\MySQL Connector C 6.1.3\lib\libmysql.lib is x86 and not x86_64.

obradley

So I should build with the 86 bit VS command prompt? Apologies for the confusion it's my first time encountering these types of issues

jsulm

@obradley You should build what you want to have. If you need x86_64 build then install x86_64 MySQL Connector version.

SGaist

Hi,

No, you should have your dependencies built for the same architecture are Qt. If you have a 64bit Qt then you need the 64bit version of the connector. There's no way to mix and match libraries built for different architectures.

obradley

Sorry I'm still confused about. The connector I have is x64 according to MySQL installer. The installer which I have for Qt is an x86 installer. Running Qt diag returns that the architechture is x86_64. So does this mean I can use the 64 bit MySQL connector? So instead of running the x64_x86 Cross Tools Command Prompt for VS2017 should I run the x86_x64 Cross Tools Command Prompt for VS2017? This would be an environment initialised for x86_x64? Or do I instead need to find an x86 version of the C connector?

Apologies again for the confusion.

SGaist

The architecture of the installer has nothing to do with the architecture of the Qt versions you installed. The same goes for Qt Creator, it can be x86 or x86_64, it does not matter when it comes to the architecture of the libraries you are using to build your application.

There's no cross-compilation going on: if you have everything as x86_64, just use the 64bit compiler.
