Unsolved libgcc_s_seg-1.dll was not found issue
-
Hello. I have been playing around with QT Creator for a few days and managed to create a very simple program. I have decided to test it and deploy it. I have followed this video:
https://www.youtube.com/watch?v=rFHPOZoqzcgWhat I have done:
- Build the project in release configuration.
- Execute windeployqt.exe command in powershell
PS C:\Qt\6.3.1\mingw_64\bin> .\windeployqt.exe "C:\Users\petrikas.lu\Desktop\WORK\QT\UTB\build-UTB_gui-Desktop_Qt_6_3_1_MinGW_64_bit-Release\release\UTB_gui.exe" C:\Users\petrikas.lu\Desktop\WORK\QT\UTB\build-UTB_gui-Desktop_Qt_6_3_1_MinGW_64_bit-Release\release\UTB_gui.exe 64 bit, release executable Adding Qt6Svg for qsvgicon.dll Direct dependencies: Qt6Core Qt6Gui Qt6SerialPort Qt6Widgets All dependencies : Qt6Core Qt6Gui Qt6SerialPort Qt6Widgets To be deployed : Qt6Core Qt6Gui Qt6SerialPort Qt6Svg Qt6Widgets Warning: Cannot find GCC installation directory. g++.exe must be in the path.

PS C:\Qt\6.3.1\mingw_64\bin>In my release folder, Some new files were created:
I have tried to launch UTB_gui and get the following error:
Could someone clarify to me what could be the issue here?
-
@lukutis222 Seems like you also need to copy libgcc_s_seh-1.dll into your app folder.
-
@jsulm
I figured that much. Is there any particular reason why I need to manually copy this file while others do not need to do that?Also, do you know where can I find this dll file?
-
@lukutis222 I don't know why it is not copied.
You can find it in your MinGW installation, simply search for it in Windows Explorer. -
@jsulm
I got it to work. Thank you very much :)
