Qmake Extra Targets

[ChrisW67]

Hi All,

I wanted to roll building my Assistant-based help into the general qmake build process so I thought I'd just shoehorn it into the pro file. I looked at the usually very clear docs and found them somewhat lacking. Nothing I did seem to generate an extra target. This is the session where I created a basic empty project and pasted the example from the docs:

chrisw@newton ~/workspace/zzbug $ cat test.pro
TARGET = test
TEMPLATE = app
CONFIG += qt warn_on
SOURCES += main.cpp

mytarget.target = .buildfile
mytarget.commands = touch $$mytarget.target
mytarget.depends = mytarget2

mytarget2.commands = @echo Building $$mytarget.target

QMAKE_EXTRA_TARGETS += mytarget mytarget2

chrisw@newton ~/workspace/zzbug $ qmake test.pro

chrisw@newton ~/workspace/zzbug $ make mytarget2
Building .buildfile

chrisw@newton ~/workspace/zzbug $ make mytarget
make: *** No rule to make target `mytarget'. Stop.

chrisw@newton ~/workspace/zzbug $
Nothing I do generates a target "mytarget" in the Makefile although "mytarget2" does get inserted. What obvious step am I missing?

The example is on Linux/Qt 4.5.2 but I get the same (non-) result on Windows(2009.3 SDK).

Run qmake with "-d" parameter and see what comes out.

Yikes... what exactly am I supposed to look for? Here are the bits surrounding mentions of the extra targets:
DEBUG 1: Project file: reading /home/chrisw/workspace/zzbug/test.pro
DEBUG 1: Project Parser: /home/chrisw/workspace/zzbug/test.pro:4 :TARGET: :=: (test)

and


DEBUG 1: QMAKE_EXTENSION_SHLIB === so
DEBUG 1: QMAKE_EXTRA_COMPILERS === moc_header :: rcc :: image_collection :: moc_source :: uic :: yacc_decl :: yacc_impl :: lex
DEBUG 1: QMAKE_EXTRA_TARGETS === mytarget :: mytarget2 :: mocclean :: mocables

DEBUG 1: QMAKE_EXT_CPP_MOC === .moc

I cannot see any obvious error messages. The complete output is attached (gzipped).

You renamed the target as ".buildfile". So try invoking "make .buildfile".

D'oh! It was always going to be something dumb! :o
