Debug/release folders with subdir template preventing from finding lib

Anselme

Hello,
i currently have a project with a structure like this :

the issue is how to link the libmylib.a for my app.exe, ignoring the debug/release folders
i'm programming with qtcreator on windows with mingw.
but i need my code to be able to be compiled on command line on a linux machine, on windows i get this build structure :

build_dir :

app
- release
- debug
mylib
- release
- - libmylib.a
- debug
- - libmylib.a

and on linux, i got this :

build dir :

app
mylib
- libmylib.a

so, from the point of view of app.pro, the path to libmylib.a changed depending on the system, preventing me to link correctly with the same .pro files on both systems.
I have two questions :

is it possible to ignore the build / release directories (automatically append them depending on the build option) ?
is it possible on command line, to call qmake on a certain way to get the exact same structure qtcreatot generates on windows ?

Hi and welcome to devnet

With DESTDIR you can specify in each .pro where to place the result/target of the run. In mylib.pro you can specify the location for storing the lib and in app.pro you can use LIBS the location where to the libs.

That doesn't really answer any of my 2 questions, but I tried a workaround using DESTDIR, I STILL i don't know what to put as DESTDIR since i don't want an absolute path, and relative paths are relative to the build directory...

Hi,

In project file:

#configure var (path where the compiler is saving result)  DESTDIR
win32-g++:CONFIG(release, debug|release): DESTDIR = $$OUT_PWD/release
linux-g++:CONFIG(release, debug|release): DESTDIR = $$OUT_PWD
win32-g++:CONFIG(debug, debug|release): DESTDIR = $$OUT_PWD/debug
linux-g++:CONFIG(debug, debug|release): DESTDIR = $$OUT_PWD
#configure var PATHCOPY
win32-g++:PATHCOPY = C:/myfolder/lib
linux-g++:PATHCOPY = /opt/myfolder/lib
#after compilation will automatically copy to PATHCOPY
QMAKE_POST_LINK = $${QMAKE_COPY} $$DESTDIR/$$TARGET $$PATHCOPY/$$TARGET

Finally fixed it, i used a .qmake.conf file to store the root directory in a shared variable, for those who are interested, here are my 3 .pro files :

project.pro

TEMPLATE = subdirs
CONFIG += ordered c++11
SUBDIRS = ircbot \
	myApp
myApp.depends = ircbot

mylib.pro

DESTDIR = $$lib_dir
TARGET = mylib
TEMPLATE = lib
CONFIG += staticlib

SOURCES += ...
HEADERS += ...
FORMS   += ...

myApp.pro

DESTDIR = $$bin_dir
TARGET = myApp
TEMPLATE = app

LIBS += $$lib_dir/libmylib.a
INCLUDEPATH += ../mylib

SOURCES = ...
HEADERS += ...
FORMS   += ...

and finally, the .qmake.conf file :

lib_dir=$$PWD/lib
bin_dir=$$PWD/bin

this successfully creates this project structure :

bin
- myApp.exe
lib
- mylib.a
project.pro
.qmake.conf
myApp
- myApp.pro
mylib
- mylib.pro

+ a build directory anywhere i want
