Qt 5.15.9 static compilation issue

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.

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.

@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.

@Cobra91151 said in Qt 5.15.9 static compilation issue:

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 ...
zlib.h not found in [] and global paths.
  => 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.
