Problems Building MySql plugin on Mac M1 Qt 6.1.2

Christian Ehrlicher

Your output only covers the configure step, not the build step. As I said (and you already told me) you have to call cmake --build or make afterwards.

@Christian-Ehrlicher OK, I can see a file CMakeError.log and there is an issue with gcc. What does the mean? Do I have to download something else or is it already somewhere on my system?

Checking whether the ASM compiler is GNU using "--version" did not match "(GNU assembler)|(GCC)|(Free Software Foundation)":

I don't see what CMakeError.log has to do with it - the configuration stage is fine. Now you only have to compile it as already said two times - giving up...

Vince2480

@Christian-Ehrlicher Thanks for helping.

Vince2480

So is it that the ASM compiler doesn't match the required gcc version?
I've installed gcc-11 using brew and it's first in the $PATH variable, but it's still defaulting ti the Xcode clang version.

Christian Ehrlicher

Is it so hard to simply type make to actually build to sources??

Vince2480

@Christian-Ehrlicher I've done that, this is what I get...

% make

make: *** No targets specified and no makefile found. Stop.

Christian Ehrlicher

@Vince2480 said in Problems Building MySql plugin on Mac M1 Qt 6.1.2:

/Users/vinceieraci/Qt/6.1.2/Src/qtbase/src/plugins/build-sqldrivers

In this directory? I doubt so - configure worked fine so there must be a Makefile or something similar.

Vince2480

@Christian-Ehrlicher No, configure didn't.

I want to check we're on the same track.
The first step was:

qt-cmake -G"Ninja" /users/vinceieraci/qt/6.1.2/Src/qtbase/src/plugins/sqldrivers -DCMAKE_INSTALL_PREFIX=/users/vinceieraci/qt/6.1.2/macos -DMySQL_INCLUDE_DIR="/usr/local/mysql/include" -DMySQL_LIBRARY="/usr/local/mysql/lib/libmysqlclient.dylib"

I think that's what you're referring to the configure step, and although the terminal output indicated success, it generated the error log that I posted earlier.

jsulm

@Vince2480 The Cake call WAS successful (according to your own Make output you posted). Forget the error log.
Do you call make in this folder: /Users/vinceieraci/Qt/6.1.2/Src/qtbase/src/plugins/build-sqldrivers ?

SGaist

Hi,

Just to be sure we are all one the same path: Qt 6 documentation:

mkdir build-sqldrivers
cd build-sqldrivers

qt-cmake -G"Ninja" <qt_installation_path>/Src/qtbase/src/plugins/sqldrivers -DCMAKE_INSTALL_PREFIX=<qt_installation_path>/<platform> -DMySQL_INCLUDE_DIR="/usr/local/mysql/include" -DMySQL_LIBRARY="/usr/local/mysql/lib/libmysqlclient.<so|dylib>"
qt-cmake --build .
qt-cmake --install

Where did you create build-sqldrivers ?
Did you properly CS into it ?

Vince2480

Thank you everyone so much for staying with me. At age 70, my brain skips what is so obvious, so I’ve spent the last couple of days going over everything I’ve done, and from what I can see, it’s all to the doc.

I’ll detail everything and I hope it will answer everything you're asking me.

This is my default zsh shell path:

vinceieraci@Vinces-MBP2 sqldrivers % echo $PATH                                              
/opt/local/bin:/opt/local/sbin:/opt/homebrew/bin:/opt/homebrew/sbin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:

Then I add:

vinceieraci@Vinces-MBP2 sqldrivers export PATH=$PATH:/users/vinceieraci/Qt/6.1.2/macos/bin

Now start the steps:

vinceieraci@Vinces-MBP2 sqldrivers % mkdir build-sqldrivers
vinceieraci@Vinces-MBP2 sqldrivers % cd build-sqldrivers
vinceieraci@Vinces-MBP2 build-sqldrivers % qt-cmake -G"Ninja" /users/vinceieraci/qt/6.1.2/Src/qtbase/src/plugins/sqldrivers -DCMAKE_INSTALL_PREFIX=/users/vinceieraci/qt/6.1.2/macos -DMySQL_INCLUDE_DIR="/usr/local/mysql/include" -DMySQL_LIBRARY="/usr/local/mysql/lib/libmysqlclient.dylib"

Files created:
vinceieraci@Vinces-MBP2 build-sqldrivers % ls -l

Hence:

vinceieraci@Vinces-MBP2 build-sqldrivers % make 
make: *** No targets specified and no makefile found.  Stop.

SGaist

Since you are using the Ninja generator, you have to call ninja to build.

Vince2480

@SGaist I'm about give up, it's beyond my abilities.
I'll try again on an Intel machine.
