[Buildroot] Configuring QMake project issue

[Yegor Yefremov]

Hi Thomas,

I followed your instructions on how to integrate own small project into BR. This is Qt project based on a *.pro file. My *.mk looks like this:

VSGUITEST_VERSION = 1.0
VSGUITEST_SITE_METHOD = local

define VSGUITEST_EXTRACT_CMDS
        cp -a $(TOPDIR)/package/vscom/vsguitest/src/* $(@D)/
endef

define VSGUITEST_CONFIGURE_CMDS
        $(QT_QMAKE) $(@D)/vsguitest.pro
endef

define VSGUITEST_BUILD_CMDS
        $(MAKE) -C $(@D) all
endef

$(eval $(call GENTARGETS))

The vsguitest.pro looks like this:


HEADERS             = \
    vstestgui.h \
    vsserialtest.h \
    vsnetworktest.h
SOURCES             = main.cpp \
    vstestgui.cpp \
    vsserialtest.cpp \
    vsnetworktest.cpp

LIBS += -lSerialPort -lQtNetwork

My problem is, that after source code copy qmake generates Makefile directly in BR's root and overwrites the main Makefile. With QSerialDevice I haven't experienced such problems. What can I do about this?

Regards,
Yegor 

P.S. what about adding QMake project type in addition to CMake type?

If you use _SITE_METHOD = local, then you don't need the custom
_EXTRACT_CMDS.

Just do:

 _SITE_METHOD = local
 _SITE = $(TOPDIR)/package/vscom/vsguitest/src/

> define VSGUITEST_CONFIGURE_CMDS

This should be:

	(cd $(@D); $(QT_QMAKE) vsguitest.pro)

otherwise:

This is because in your _CONFIGURE_CMDS, qmake gets executed inside the
Buildroot top directory.

So far, we don't have any package using Qmake inside the tree, which is
why we don't have a package infrastructure for them. So either we could
document how to create Qmake package (which is quite easy), or we could
add a package infrastructure for them.

Regards,

Thomas
