Qt 6.3.2 compilation issue

I want to build Qt 6.3.2 but it has a lot of issues during the compilation process.

I use the following libs to build with Qt:

  1. MySQL (mysql-8.0.30)
  2. OpenSSL (openssl-1.1.1q)
  3. Zlib (zlib-win-build-1.2.12)

My cmake batch command:

cmake.exe --trace-expand --trace-redirect=cmake.trace -DCMAKE_BUILD_TYPE=%qtBuildMode% -DBUILD_SHARED_LIBS=OFF -DQT_BUILD_EXAMPLES=OFF -DCMAKE_PREFIX_PATH="C:\\LLVM\\x64\\static\\debug;" -DZLIB_INCLUDE_DIR="C:\\ZipDev\\zlib-win-build-1.2.12" -DZLIB_LIBRARY="C:\\ZipDev\\zlib-win-build-1.2.12\\build-VS2022-MT\\x64\\Debug\\libz-static.lib" -DZLIB_USE_STATIC_LIBS=ON -DINPUT_static_runtime=ON -DFEATURE_ltcg=OFF -DBUILD_qtwebengine=OFF -DOPENSSL_ROOT_DIR="%qtBuildOpenSSLRootPath%" -DFEATURE_openssl_linked=ON -DOPENSSL_USE_STATIC_LIBS=TRUE -DOPENSSL_MSVC_STATIC_RT=TRUE -DINPUT_sql_mysql=ON -DMySQL_INCLUDE_DIR="%qtBuildMySqlIncludeDirsPath%" -DMySQL_LIBRARY="%qtBuildMySqlLibsPath%" -DCMAKE_INSTALL_PREFIX="%qtBuildPath%" -G Ninja %qtBuildSourcePath%

I have fixed many of them but still need to fix this one.

Any ideas what could cause such error? Thank you.

This issue with mysqlclientMTd.lib occurs due to the mismatch beween compiler versions as described here: https://developercommunity.visualstudio.com/t/__imp___std_init_once_complete-unresolve/1684365. This library was compiled with Visual Studio 2022 compiler. I used x64 Native Tools Command Prompt for VS 2019 to build Qt 6.3.2 which means it could not find this new function: __std_init_once_link_alternate_names_and_abort. This function is from STL’s import library: msvcprt.lib and was only added in the VS 2022 version: 17.2.5. So, I fixed this error by rebuilding this mysqlclientMTd.lib for VS 2019 compiler, since I need Qt 6.3.2 for VS 2019 compiler.

Also, I have got another error, at this time with libz-static.lib in Release build:

So, to fix this error: fatal error C1900: Il mismatch between 'P1' version '20211014' and 'P2' version '20210202', I have to build the libz-static.lib for VS 2019 compiler as well. Now, everything compiles (debug/release) without any error. The issue is resolved.
