:-1: error: Aborting.Here is proper link for releases: https://github.com/probonopd/linuxdeployqt/releases
I have no idea why GitHub does not show a handy link to that page anywhere.
Regarding other bug - no idea, I have never encountered it myself.

Don't download the ZIP, download the .appimage file (linuxdeployqt-continuous-x86_64.AppImage, 14 MB).
@sierdzio well yes i did that and this was the error found in Terminal

Yeah, that happens a lot. Does your application use MySQL? Some workarounds are available https://github.com/probonopd/linuxdeployqt/issues/235 Basically you can instruct linuxdeployqt to skip this plugin (https://github.com/probonopd/linuxdeployqt/pull/253).

@sierdzio so what do you think abt this error
ERROR: Please ensure that all libraries can be found by ldd. Aborting.
what am i missing?@Vineela said in Error when deploying Qt Application:

ERROR: Please ensure that all libraries can be found by ldd. Aborting.
what am i missing?Ignore it. Focus on this, which is the real error:
ERROR: ldd outputLine: "libmysqlclient_r.so.16 => not found"
And skip that plugin. According to the docs, this should work:
-exclude-libs=libqsqlmysqlBut I've never tried that option myself so can't say with certainty.
Why you can skip/ ignore? The error is about a plugin. Your application does not use that plugin, so it won't load it at runtime, and that means it will not crash with "missing library" in practice.

That does not sound to be Qt-related.
Use Dropbox maybe? Format your pendrive? I don't know what the problem is so I can't help. AppImage files are normal binary files, they should copy just like any other file.

and what shud i do with this , -exclude-libs=libqsqlmysql??? -
When does this error show up? During compilation? Linking? Or when you try to run the executable?
I think the issue is that Qt version installed in your system is different from one ThinClient is linked against. If you have your AppImage binary created already - run that instead of ThinClient file itself.
