qmake bug?

[William Wilson]

Qt version: Qt 4.3.0
OS: Linux

I'm trying to separate binaries for debug and release builds. On Linux, qmake does not generate scripts for making debug versions (g++ -g). On Win32 platforms, this works perfectly fine. Am I missing something or is it a qmake bug? Thanks in advance for any workarounds.
-------------------------------------------------------------

qmake usage:
qmake -makefile test.pro "CONFIG+=build_all"

make

------------------------------------------------------------
test.pro file:


TEMPLATE = lib
TARGET = test
CONFIG(debug, debug|release)
{
DESTDIR = ../../bin/debug/plugins
OBJECTS_DIR = ../../bin/debug/obj
MOC_DIR = ../../bin/debug/moc
} else
{
DESTDIR = ../../bin/release/plugins
OBJECTS_DIR = ../../bin/release/obj
MOC_DIR = ../../bin/release/moc
}
----------------------------------------------------

You need to add:CONFIG += debug_and_release

Unfortunately, even that doesn't work on Linux. All i want is to generate separate binaries for "debug" so that i can step through using gdb and "release" binaries for distributing - from the same .pro file. You guys may already have a solution for this kind of build. Can someone please help?

Hi William,

my posted solution DOES work on linux - thats the way I use it.
In order to be sure that qmake really re-generates the Makefiles:
-make clean
-delete all make files
-invoke qmake again

Good luck,

Tom

Tom,
Can you post your relevant .pro file code? May be there is a difference in the way that i'm using it. What is your Qt version? Thanks again.

here we go ...

Thanks Tom.
It works fine with your example:


CONFIG(debug, debug|release) {
win32: TARGET = $$join(TARGET,,d)
TARGET = $$join(TARGET,,,_debug)
}

And not with this:


CONFIG(debug, debug|release)
{
DESTDIR = ../../bin/debug/plugins
OBJECTS_DIR = ../../bin/debug/obj
MOC_DIR = ../../bin/debug/moc
} else {
DESTDIR = ../../bin/release/plugins
OBJECTS_DIR = ../../bin/release/obj
MOC_DIR = ../../bin/release/moc
}

:-(

qmake is a bit picky when it comes to scopes (http://doc.trolltech.com/latest/qmake-advanced-usage.html#scopes). It should be


CONFIG(debug, debug|release) {
...
} else {
...
}

[William Wilson]

That worked. Thank you jpn!
