Qt static with MySQL issue

[SGaist]

I would add MYSQL_LIBS=-lmysqlclient.

[Cobra91151]

@SGaist

Ok. I will try it and reply. Thanks.

[Cobra91151]

I added the MYSQL_LIBS="-lmysqlclient" to configure:

configure.bat -debug-and-release -%qtBuildType% -opensource -nomake tools -nomake examples -no-ltcg -sql-mysql -I "%qtBuildMySqlIncludePath%" -L "%qtBuildMySqlLibPath%" MYSQL_LIBS="-lmysqlclient" -ssl -openssl -openssl-linked -I "%qtBuildOpenSSLIncludePath%" -L "%qtBuildOpenSSLLibPath%" OPENSSL_LIBS="-lUser32 -lAdvapi32 -lGdi32 -lCrypt32" OPENSSL_LIBS_DEBUG="-lssleay32MTd -llibeay32MTd" OPENSSL_LIBS_RELEASE="-lssleay32MT -llibeay32MT" -prefix "%qtBuildPath%"

But I get the issue:

I think I should also provide the libmysql to MYSQL_LIBS or the problem is with mysql-5.7.23.

[Cobra91151]

I have found the issue! Adding this line MYSQL_LIBS="-lmysqlclient" to configure for some reason breaks the detection of MySQL. I will try again to confirm it.

[Cobra91151]

Yes, I was right. Adding MYSQL_LIBS="-lmysqlclient" breaks the detection of MySQL - 100% confirmed.

[Cobra91151]

I run a few tests and found that Qt requires libmysql.lib to configure, but since it dynamic lib it won't work in my case. I think I should try to rename mysqlclient.lib to libmysql.lib and test it.

[Cobra91151]

No, it fails with detection the MySQL if libmysql.lib has been changed, renamed or removed.

[Cobra91151]

I think I have found the issue.

This line of code in the file - configure.json - { "libs": "-lmysqlclient", "condition": "!config.win32" } disables mysqlclient (static) lib because condition states that !win32, means not Windows system. I will change it and try again.

[Cobra91151]

I have tried different solutions but it all failed.

Any ideas how to make it compile with the static library? Thanks.

[Cobra91151]

@SGaist said in Qt static with MySQL issue:

MT and MD are just related to the Windows runtime type you'll be using.

The issue must be with this. I checked Qt configure log and the same errors are displayed with MFC static test project in VS 2017.

It leads to Qt configure errors. For some reason it conflicts with MSVCRT lib.

[Cobra91151]

I have run some tests on another PC, the same errors are present there. So, I think the mysqlclient is build for another compiler, maybe, MinGW or older VS versions. I need to find the MySQL source code and compile mysqlclient (static) lib for Visual Studio 2017. Any ideas where I can find it? Thanks.

[Cobra91151]

I have found the source code here: https://dev.mysql.com/downloads/mysql/
Now I will read docs how to compile it.

[Cobra91151]

I have built the MySQL libs, added to the MFC test project and it displays the same errors. It's strange. Next, I will install virtual machine, VS 2015 and build the test project there.

[Cobra91151]

I have found the issue and built the MySQL libs. Then I reconfigure Qt, all built well but when I build my project I get the issue:

So, mysqlclient.lib already has the OpenSSL?

Also, I have the issue with debugging the app:

I have the debug version of the library, but I want to know how to add it to the configure? I have tried: MYSQL_LIBS_DEBUG/MYSQL_LIBS_RELEASE but it fails with detection of MySQL. Any ideas? Thanks.

[Cobra91151]

I have found that I must have the OpenSSL built statically as /MD runtime lib in order to compile my project. The question is where to get such library or source code? Thanks in advance.

[Cobra91151]

I have fixed the issue with MYSQL_LIBS_DEBUG/MYSQL_LIBS_RELEASE libs by creating the advanced batch script file. So, it compiles the debug/release separately, has a support to remove Qt source dir and unpack the source from archive using WinRaR for the next compilation.

By the way, I get issue when building static Qt in the debug mode:

By pressing Retry it continues to build Qt successfully.

Still one more issue to fix:

[Cobra91151]

So, I have fixed the issue:

Solution:
OpenSSL source code: 1.1.1
MySQL source code: 5.7.23

1. Compile static OpenSSL libs with /MDd | /MD flags for Debug/Release mode
2. Compile MySQL static libs (/MDd | /MD) with pre-compiled OpenSSL static libs (option 1)

I test it in the simple console app in the Visual Studio 2017:

Code:

#include <iostream>
#include <mysql.h>
#include <openssl/bio.h>
#include <openssl/ssl.h>
#include <openssl/err.h>
using namespace std;

int main()
{
	cout << "Hello World!" << endl;
	cout << "Hello!" << endl;
	SSL_load_error_strings();
	ERR_load_BIO_strings();
	OpenSSL_add_all_algorithms();
	printf("MySQL client version: %s\n", mysql_get_client_info());
	system("PAUSE");
	return 0;
}

The result:

Now I configure Qt statically with these libs (MySQL & OpenSSL), first in the Debug mode. It find MySQL and OpenSSL during configuration but then I get this issue:

The question is how to fix this issue with Qt? Thanks in advance.

[aha_1980]

This post is deleted!

[Cobra91151]

@aha_1980

My issue is not solved because Qt for some reason doesn't build it. The question is why it can't build it properly now?

[Cobra91151]

I think that Qt is not compatible with the following OpenSSL libs:

1. libcrypto.lib
2. libssl.lib
