program startup error about librecad HOT 15 CLOSED

Win11 also :

from librecad.

I have the same issue with the new installer.
From this comment, it looks related to libstdc++
huihut/OpenCV-MinGW-Build#18 (comment)

from librecad.

fixed by 3f05709

The problem appears to be an issue due to the mingw-64 version with gcc-8.10 . Fixed by using mingw-64, gcc-11.20

from librecad.

I suppose the failure is not limited to win11.

Did anyone try the installer on older versions?

Is this related?

now I downloaded and installed LibreCAD-latest-1-g423ce8a4-win64.exe. I wanted to run the LibreCAD program.
The same problem still persists.

from librecad.

For Linux appimage, the issue appears to be clear, need to deploy the qt SVG libraries; looks like lots of people have trouble for the current appimage builder with qt6

For windows, need troubleshooting

from librecad.

Win64 installer is fixed with 494a9c9

Looks like Linux appimage is the trouble for qt-6. 6

from librecad.

same problem persists.

Sorry, looks like I made a mistake here. The issue was an incorrect qt version was specified in packaging.

The latest build (just downloaded) generates the same error:
$ /home/opt/LibreCAD-latest-9-gc8a920a0.AppImage

Yes, we still need a way to build a Linux image for qt6

I can reproduce this issue on win10.

from librecad.

Linux appimage is fixed by manually copying the qt6 libraries over. The building tool simply quit after detecting an empty qt profile

The windows issue is still not clear to me, seekg() is part of glibc and the library is located and copied into the installer.
