D11.2 + FireDAC + MySQL 64 bit not working

Recommended Posts

Hello,

I attach a stupid D11.2 project with FD on MySQL compiled in 32 and 64 bit windows.

Simple connection to mysql using libmysql.dll 32 and 64.

With 32 everything is ok, with 64 it is not working.

Before you ask:

- FDDrivers.ini is located only in one place with nothing inside (it is the base embarcadero file)

- In the source you can see my connection params

- I don't use TFDPhys... because I want my exe to use local (same exe path) DLLs

- I followed Embarcadero guidelines (vs2015 runtime, etc.)

- I tryed with libmysql.dll from 8.x and 5.x (also the 5.7.29 as Embarcadero says), but same bad results

 

Link to archive: https://we.tl/t-8ydNpkhi5u

(If link is gone, tell me!)

 

Any idea?

 

Thanks

do you try this, too?  "FDDrivers.ini " NOT EMPTY!!!

Note: If you use a 64-bit SQL server, the client DLLs will also be 64-bit. To connect at design time or to use this server with a 32-bit application, download 32-bit DLLs from http://dev.mysql.com/downloads/connector/c/#downloads

Alternatively you may put the required files in any other folder, and specify their path in FDDrivers.ini:


[MySQL]
VendorLib=<folder>\libmysql.dll

If the MySQL client library has not been installed properly, an exception is raised when you try to connect:

[FireDAC][Phys][MySQL]-314. Cannot load vendor library [libmysql.dll]. The specified module could not be found. Check [libmysql.dll], which is located in one of the PATH directories or in application EXE directory.

hi,

I have many 4.0 industry software made in D11x and MySQL

in Firedac I use libmysql.dll from the MySQL folder, this should be inserted in TFDPhysical vendorlib property

under Windows Server 2016, 2019, 2022 works fine

you have to setup microsoft visual c runtime before https://learn.microsoft.com/it-it/cpp/windows/latest-supported-vc-redist?view=msvc-170

Hi, Thanks.

Did you try to download the 7z archive and run the executable at Win64? It is not running on any machine. I did the VC2015 setup and set the VendorLib, too, but nothing changes. Win32 is ok, Win64 give the error:

[FireDAC][Phys][MySQL]-314. Cannot load vendor library [libmysql.dll]. The specified module could not be found. Check [libmysql.dll], which is located in one of the PATH directories or in application EXE directory.

my test using MySQL 8.0.26 Community + RAD 11.2 Alexandria + FireDAC + LibMySQL.dll (libcrypto-1_1-x64.dll, libssl-1_1-x64.dll) (64bits) + App in 64bits

  • NONE DLL on \Windows\SystemXXXX
  • NONE PATH MySQL defined
  • NONE FDDrivers.ini definition!  just default by RAD
    • [FDDrivers.ini]
      • Encoding=UTF8
  • LibMySQL.DLL, libcrypto-1_1-x64.dll, libssl-1_1-x64.dll on exe folder

Tip: RAD Studio IDE works in 32-bit, that is why it cannot connect with MySQL 8.0, wich is only available in 64-bit. To avoid this connection issue you can use MySQL 5.7.29, which is the most recent 32-bit version of MySQL.

How the bitness of server relates to bitness of client? Nobody requires you to access x64-Apache-driven website with strictly x64 browser.

You really never heard of amd-x64.google.com or itanium64.en.delphipraxis.net? 😄

this is on HELP from RAD Studio, it's not mine comment! 

That's why "Ian Barker" (Embarcadero MVP) is even embarrassed to say that Embarcadero got it wrong once again!!!

I stalk everyone. That is the job of admins and mods.

Also - large fonts and colors does not improve communications.

remove the options from "menu", or define "just one option to choice" (no color, no size, no nothing...), it's done! :classic_tongue:

is it really necessary all this?

odstráňte možnosti z "menu" alebo definujte "len jednu možnosť na výber" (žiadna farba, žiadna veľkosť, nič...), je to hotové! :klasický_jazyk:

je toto vsetko naozaj potrebne?

Those possibilities are justified. They should be used with caution. When I see those huge and bold texts with parrot colors, I don't feel comfortable.

hi,

I use D11.x with MySql 8.x both in 32 and 64bit.

You have to use the DLL found into bin folder of the MySql installation and put it into fdphysical lib name.

If your system is virgin then install the runtime of visual c.

https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist

put at runtime the 64bit lib $ifdef win64 ... and develop with 32bit

Install mysql 32 for 32 dll and mysql 64 for 64 dll
