Qt (Static Build) Unresolved Externals (MSVC2017)

jmarkson

After a day or so I've finally gotten a (or what should be) statically compiled Qt Library. I have downloaded the single zip file src that is on the /download page. ave ran configure.bat and jom, yet when I try to make a stand-alone application I run into 171 Unresolved externals from the following libraries

Qt5Gui.lib
Qt5Core.lib
Qt5Widgets.lib
qwindows.lib

I have googled for around 40 minutes to an hour now with no solution found. I found many posts with similar issues on SO and Qt Forum which say "Oh I included this and that and it works!", but I have included/linked all I have found (and much more) in hoped for a fix with nothing working.

TL;DR Libs listed above are giving out unresolved externals and I've no idea why.
All linked libraries:

/kernel32.lib
user32.lib
shell32.lib
uuid.lib
ole32.lib
advapi32.lib
ws2_32.lib
gdi32.lib
comdlg32.lib
oleaut32.lib
imm32.lib
winmm.lib
qtmain.lib
opengl32.lib
qwindows.lib
Qt5PlatformCompositorSupport.lib
d3d9.lib
qtfreetype.lib
Qt5Core.lib
Qt5Gui.lib
Qt5Widgets.lib

All includes (across all files)

#include <QtGui\qwindow.h>
#include <QtWidgets/QMainWindow>
#include "ui_statictest.h"
#include "statictest.h"
#include <QtPlugin>
#include <QtWidgets/QApplication>

I'm not an expert in this area. But just as a heads-up before others try to help you: it might help if you gave a few examples (from your 171) of precisely what symbols are reported unresolved, so that someone could perhaps identify a missing library.

Good point.
First error for each different lib:

So, for example, just taking the unresolved __imp__GetThemePartSize@28, I see in your output, https://msdn.microsoft.com/query/dev10.query?appId=Dev10IDEF1&l=EN-US&k=k(GetThemePartSize);k(DevLang-C);k(TargetOS-WINDOWS)&rd=true states you will need static library UxTheme.lib, which I don't see among your libraries?

Also I note that says that is for "desktop apps only", since you're linking statically I don't know if there is a compiler/linker option you might need to pass to indicate that....

jmarkson

I'll take a look at the UxTheme lib now. As for the compiler/linker option tos I've already done that.
//edit
You were right! Including that lib has taken the 171 unresolved externals to 154
Going further down the list of errors and including libs of the functions on MSDN is now only decreasing by 0-2 errors per lib.

JonB

An unresolved was _pcre2_config_16.

So I'm doing your Googling for you ;-)
https://doc.qt.io/qt-5/qtcore-attribution-pcre2.html
http://www.regular-expressions.info/pcre2.html
Search for maybe pcre2 windows binary

Does that _16 indicates it's 16-bit....?? Good luck :)

_hb_buffer stuff? See https://stackoverflow.com/questions/41765673/static-linking-against-qt-on-windows-using-cmake

jmarkson

pcre2 was not in the path Qt docs said it was (Might be the issue) as for the HB errors does this mean they're unfixable? Checking the SO you linked the bug report is still unresolved.
