QT6 run the .exe but point out "lack of libwinpthread-1.dll"

[pedisChen]

I have compile Qt6.5.3 Src file by Mingw and built a static link version QT.
my configuration is :
configure.bat -static -prefix "C:\Qt\6.5.3\mingw_64_static" -release

and then I use the "mingw_64_static" to compile a program, got a “.exe” file. I attemped to run the .exe on another computer on win11.
but it fails，system point out that “libwinpthread-1.dll” is missing.
why? and how to solve it?Thank you

Hi,

You did not use the -static-runtime option when calling configure.

@SGaist it works，but why? I followed the website instruction（https://doc.qt.io/qt-6.5/configure-options.html），there is no requirement to add the option -static-runtime，what is the relationship between them?

@pedisChen said in QT6 run the .exe but point out "lack of libwinpthread-1.dll":

but why?

Because without -static-runtime runtime libs like pthread will not be built as static libs, instead they will be linked as shared libs.

Have a look at this https://forum.qt.io/topic/156422/trying-to-build-a-static-qt-for-windows

There @mzimmers tried to do exactly the same thing build a static Qt 6.5.3 with MinGW.

@jsulm I understand now，thank you
