Hi,

That will not work. The rpath needs to be $ORIGIN. A string. Not a
variable that is expanded.
Also, I used the wrong syntax before. Escaping this string is
difficult since it contains an "$". This should work:
QMAKE_LFLAGS=-Wl,-rpath,\'\$\$ORIGIN\'
If you use that one, you should find that your program keeps working
even if you move the directory that contains it and the libraries to
somewhere else. With your current method, the program will only work
if the libraries are in "/home/igor/Qt/5.5/gcc_64", a hardcoded path.
Now I understand what are you talking about. You are right.
I found the next solution in QtCreator sources:
QMAKE_RPATHDIR += \$\$ORIGIN
QMAKE_RPATHDIR += \$\$ORIGIN/../lib
RPATH = $$join( QMAKE_RPATHDIR, ":" )
QMAKE_LFLAGS += -Wl,-z,origin \'-Wl,-rpath,$${RPATH}\'
QMAKE_RPATHDIR =
It works now.
Thank you.

In my Makefile I have:
LFLAGS = -Wl,-O1 -Wl,-rpath,/home/igor/Qt/5.5/gcc_64
-Wl,-rpath,${ORIGIN} -Wl,-rpath,/home/igor/Qt/5.5/gcc_64/lib

That doesn't do anything useful. It just uses an absolute path. If you
move the executable to a different directory, it stops working.
You can verify that by looking at the Makefile. For example, here,
this:
QMAKE_RPATHDIR += ${ORIGIN}
becomes:
-Wl,-rpath,/home/realnc/projects/myapp/
Which is completely useless.
Do do what you want, you really need to pass the string "$ORIGIN" to
the linker:
QMAKE_LFLAGS += -Wl,-rpath,\$\$ORIGIN
This results in:
-Wl,-rpath,$ORIGIN
in the Makefile.

Hi,
Got it:
QMAKE_RPATHDIR += ${ORIGIN}

You should rather utilize rpath, and set it e.g. to $ORIGIN

Interesting, but "QMAKE_RPATHDIR += ." doesn't work. It require full
path to work correctly...
qmake doesn't support it. You have to do it by hand:
QMAKE_LFLAGS += -Wl,-rpath,\$\$ORIGIN/libs
And then I put all libraries in the "lib" directory of the
execututable.
(And this is obviously linker and platform specific.)
