[SOLVED][Mac][Qt5.2] Error: Circular dependency dropped.

_Dima

Could you please help me with following issue?

There is some small project (it's only test project for more good visibility, real project is more difficult):
@QT =
TEMPLATE = aux
TARGET = installer

win32{
QMAKE_POST_LINK += $$quote($${QMAKE_COPY} "C:\Users\ruslan\Projects\TestProject\test_unit.exe" "C:\Users\ruslan\Projects\TestProject\bin")$$escape_expand(\n\t)
}else:macx{
QMAKE_POST_LINK += $$quote($${QMAKE_COPY} "/Users/ruslan/Documents/TestProject/test_unit" "/Users/ruslan/Documents/TestProject/bin")$$escape_expand(\n\t)
}

installer.commands = $$QMAKE_POST_LINK
QMAKE_EXTRA_TARGETS += installer
PRE_TARGETDEPS = installer@

During building the error is occurred:
error: Circular installer <- installer dependency dropped.

What does it mean?

PS: compile output:
@

andreyc

These two lines generate a circular dependency
@
TARGET = installer
PRE_TARGETDEPS = installer
@

In Makefile it looks like below
@
...
TARGET = installer
...
$(TARGET): installer $(OBJECTS)
...
@

As a result the TARGET depends on itself.

Thank you very much!
It has helped me.
I thought that lines:
@installer.commands = $$QMAKE_POST_LINK
QMAKE_EXTRA_TARGETS += installer
PRE_TARGETDEPS = installer@
they are related to the project "installer". I mean that I add commands to the "installer" and I add installer to the "targets".
But I can to do following:
@
TARGET = installer

#install is separate variable
install.commands = $$QMAKE_POST_LINK
QMAKE_EXTRA_TARGETS += install
PRE_TARGETDEPS = install
@
