Qt 5.15.9 static compilation issue

[Cobra91151]

Hello!

I want to build Qt 5.15.9 statically with MySQL. I got the following error during compilation process:

It seems that crc32 objects are present in both libraries. Any ideas how to resolve this collision issue? Thank you.

Hello!

Great! I have successfully built Qt 5.15.9 statically. The issue is resolved.
Thank you.

[Christian Ehrlicher]

Rename them in one of the libraries or make them static (if possible) so they're not visible outside.

Using lib /list command I have found this crc32.c.obj exists in mysqlclientMTd.lib, but it comes fromzlib library.

What do you meant by rename them? Thanks.

@Christian-Ehrlicher

I found the similar issue: https://bugreports.qt.io/browse/QTBUG-104728?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aworklog-tabpanel

I think, zlib version which uses Qt is different from zlib version which MySQL library uses. So, in order to fix it I must use the same version for both libraries.

[Cobra91151]

@Christian-Ehrlicher

I have found a solution to remove the object from library: lib /remove:"extra\zlib\zlib-1.2.12\CMakeFiles\zlib.dir\crc32.c.obj" mysqlclientMTd.lib (https://learn.microsoft.com/en-us/cpp/build/reference/managing-a-library?view=msvc-170). I think, this could help.

I am still curious how to rename those objects in the library? What commands/programs you use to rename them? Thanks.

I talked about functions, not generated object files.
And yes it's correct - you must not mix different version of one library :)

@Christian-Ehrlicher

What commands should I provide to Qt so it use my zlib library during compilation?
I added the following commands -system-zlib ZLIB_INCDIR="C:\\ZipDev\\zlib-win-build-1.2.13" ZLIB_LIBDIR="C:\\ZipDev\\zlib-win-build-1.2.13\\build-VS2022-MT\\x64\\Debug\\libz-static.lib" to configure. Also I tried to add it to the PATH but it still can not find this library by configure script.

config.log

looking for library zlib
Trying source 0 (type inline) of library zlib ...
zlib.h not found in [] and global paths.
  => source produced no result.
Trying source 1 (type inline) of library zlib ...

  => source produced no result.
Trying source 2 (type inline) of library zlib ...
  => source failed condition '!config.msvc'.
Trying source 3 (type inline) of library zlib ...
  => source failed condition 'config.wasm'.
test config.qtbase.libraries.zlib FAILED

Using system zlib ...................... no

Any ideas? Thanks.

@Christian-Ehrlicher

Hello!

So, I have found the correct commands to add Zlib to Qt configure script.

-system-zlib ZLIB_INCDIR="C:\\ZipDev\\zlib-win-build-1.2.13" ZLIB_LIBDIR="C:\\ZipDev\\zlib-win-build-1.2.13\\build-VS2022-MT\\x64\\Debug" ZLIB_LIBS="libz-static.lib"

Now, it detects my Zlib library.

Using system zlib ...................... yes

I am still facing the next issue:

mysqlclientMTd.lib(my_compress.c.obj) : error LNK2019: unresolved external symbol compress referenced in function my_compress_alloc
mysqlclientMTd.lib(my_compress.c.obj) : error LNK2019: unresolved external symbol uncompress referenced in function my_uncompress

It seems that MySQL lib with my Zlib was built with errors using Ninja. I will try to build it with VS 2022.

[Cobra91151]

I run my test project example and found out that mysqlclientMTd lib need the additional include to the Zlib lib to fix these issues:

mysqlclientMTd.lib(my_compress.c.obj) : error LNK2019: unresolved external symbol compress referenced in function my_compress_alloc
mysqlclientMTd.lib(my_compress.c.obj) : error LNK2019: unresolved external symbol uncompress referenced in function my_uncompress

So, I added libz-static.lib lib path to this command:

MYSQL_LIBS="-lmysqlclientMTd -lAdvapi32 -lUser32 -lCrypt32 -lGdi32 C:\\ZipDev\\zlib-win-build-1.2.13\\build-VS2022-MT\\x64\\Debug\\libz-static.lib"

Now, it detects the MySQL library.

MySql .................................. yes

So, Ninja / VS 2022 compilers was not the case here.
