use -v to see invocation

I would like to see if this error can help me to solve
the problem.

How / where to "use -v" in Qt?

:-1: error: linker command failed with exit code 1 (use -v to see invocation)

I cannot test. I don't know if it can be done a better way or somewhere specific in Creator, but I think that if you edit your .pro to add line

QMAKE_LFLAGS += -v

and then re-run qmake from menu/complete rebuild that would now pass -v to linker/ld.

Yep, even 10 years ago someone said

After looking carefully at what is going on - Doing a "Clean All" and then rebuild through Qt Creator is not sufficient to pick up any changes to the linker flags such as those provided by the QMAKE_LFLAGS entry in the .pro file.

You need to actually delete the entire debug / delete build directory, and then do a rebuild.

So You need to actually delete the entire debug / delete build directory, and then do a rebuild. ! But another guy there claims

Another option is to re-run qmake after you have changed .pro file.

If not it's not the right way to do it but

LIBS += -v

might do it.

However, even without -v argument to ld, doesn't Creator's "Build Output" pane already show the complete command-line invocation anyway, so you won't find out any more even if you pass -v to ld?

@JonB said in use -v to see invocation ??:

LIBS += -v

Adding to .pro , either way, did not show and more erro details .

Here is the latest snippet of the output

there is one more not analyzed error :

I could use some help with
