Qt 6.5.0 static Release libs overrides the Debug libs issue

Cobra91151

Hello!

I have built Qt 6.5.0 static successfully first for Debug and then for Release mode. When I try to build my project in Debug mode it displays the following errors:

When I compile Qt 6.5.0 for Debug/Release mode in separate folders it works well. The issue here is that Release build overrides the Debug build when I compile it in the same folder, for example: C:\QtStatic\6.5.0\msvc2022_64.

I have tested it several times. This is clean Qt build without any additional libraries. I used the following commands:

Debug:

cmake.exe --trace-expand --trace-redirect=cmake.trace -DCMAKE_BUILD_TYPE="Debug" -DBUILD_SHARED_LIBS=OFF -DQT_BUILD_EXAMPLES=OFF -DINPUT_static_runtime=ON -DFEATURE_openssl_linked=OFF -DOPENSSL_USE_STATIC_LIBS=FALSE -DOPENSSL_MSVC_STATIC_RT=FALSE -DFEATURE_ltcg=OFF -DBUILD_qtwebengine=OFF -DCMAKE_INSTALL_PREFIX="C:\\QtStatic\\6.5.0\\msvc2022_64" -G Ninja C:\\QtBuild\\qt-everywhere-src-6.5.0

Release:

cmake.exe --trace-expand --trace-redirect=cmake.trace -DCMAKE_BUILD_TYPE="Release" -DBUILD_SHARED_LIBS=OFF -DQT_BUILD_EXAMPLES=OFF -DINPUT_static_runtime=ON -DFEATURE_openssl_linked=OFF -DOPENSSL_USE_STATIC_LIBS=FALSE -DOPENSSL_MSVC_STATIC_RT=FALSE -DFEATURE_ltcg=OFF -DBUILD_qtwebengine=OFF -DCMAKE_INSTALL_PREFIX="C:\\QtStatic\\6.5.0\\msvc2022_64" -G Ninja C:\\QtBuild\\qt-everywhere-src-6.5.0

The Qt 6.5.0 static compilation process in both cases completes successfully but it seems that some Qt 6.5.0 Debug libraries gets overriden by Release libraries. Can anyone reproduce this issue? Is there a way to track down and solve this issue? Thank you.

Hello!

I have built successfully many Qt versions to the same install (PREFIX) directory. Also, it does not matter the shared or static builds. Additionally, Qt officially does compile/provide the debug/release builds to the same directory as well.

I do not use this flag: -debug-and-release because I need to provide two different versions (Debug/Release) of additional libraries at once, for example: MySQL/OpenSSL/Zlib. So to make it simple, I compile it as separate builds. As you can read in my main post, the first goes for debug and then for release mode. I do not think the Qt 6.5.0 changes it because the default version for VS 2019 from for example: MaintenanceTool installs the debug/release builds in the same directory. So, this issue must be fixed. Thank you.

@Cobra91151 Add
-DCMAKE_VERBOSE_MAKEFILE=ON
to check which module build misses flag -g

@JoeCFD

Ok. I will try it and reply later. Thank you.

Good. I have built Qt 6.5.0 statically with this command: -DCMAKE_VERBOSE_MAKEFILE=ON and got the cmake trace files for Debug & Release modes.

cmake_Debug.trace: https://mega.nz/file/4QoyFAhb#MYq4nbM08YTEqZhnUEBWAi2atAj2tPPO14sm4W30gN0
cmake_Release.trace: https://mega.nz/file/dBIhRLoY#bEITaLweEq78TrBMP7Iq_XJzBmzBx171cu7FMYAzIjc

I can not find any -g flags there. During Qt 6.5.0 static compilation I got the following output:

There is only -Gw flag but not -g? Thanks.

Hello!

I have reported this issue with Qt 6.5.0 static build here: https://bugreports.qt.io/browse/QTBUG-113260

DerReisende

@Cobra91151 I don‘t think you can have both Release and Debug builds in the same PREFIX folder. Somewhere on the Qt website is a build instruction document how to build Qt and they mention a -debug-and-release flag - which only works for shared library builds but not for static. So I guess you have to use different locations.
