EZX on a1200

[skorianez]

Hi , I want to compile prg with a1200, but de ezx-0.2 come with a example that I can not compile.
The Makefile on helloworld directory come with a ref to a lib that dont exist on my a1200:
-lezxnotification

I don't have im my phone a file libezxnotification.s

Can any one give some hints?

Thanks in advance

lib is A1200 is changed. it's name doesn't have -xscale-r suffix like A780/E680i. so i change LIBS name in .pro file from (for A780/E680i)

now ezxcrosstool can compile my app. BUT it got a new Error.

Undefined reference to ZApplication::setMainWidget (QWidget*)
and
Undefined reference to 'vtable for MyWidget'

any ideas about this? if I try to compile no UI application. it's work. but It's error when compile application that have a Widget.

PS. I build sam7's ezxcrosstool and use his ezx-dev plus qmake.
every application work fine on my A780. sample .pro is from sam7's Helloworld but create new project file helloworld.pro and Makefile with qmake.

Yes, I had changed it.
But I got more errors than you.

Changing the Makefile if more libs:
LIBS=-lezxappbase -lqte-mt -lezxjpegutils -lezxjpeg -lipp-jp -lezxexif -lipp-codecJP

I got less error:

you need to reverse engineer the headers and modify the dev-ezx ones to adapt the new changes that have been made for the a1200. Thus in order to reconstruct from scratch the library headers files from the stripped binaries present on the phone you can play with:

arm-linux-objdump -T --demangle libezxappbase.so
arm-linux-nm -aDC libezxappbase.so

[eakrin]

@bragon
how can i reverse engineering a1200 lib? did you mean we should create new header file (*.h) for A1200 to use with ezx-crosstool.


BTW there is no ZApplication::setMainWidget inside it. how can we create graphic interface application with out setMainWidget.

I attached result file from objdump and nm on libezxappbase.so.

[rpconnect]

@eakrin
i'm not sure if this will help, but i noticed that the ezxappbase contains a ZApplication::showMainWidget(QWidget*) (at least i found in in the files in your zip file above), so i gave it a quick try with a ezx version of the drawdemo from the qt examples and showMainWidget seems to work in place of setMainWidget (at least for my current e680i builds and tests), so you might try the same replacement in the helloworld app you are trying to build.

it also looks like the UTIL_CST functions (for the native ezx lower tool bar control), the ZMessageBox functions, as well as the RES_ICON_reader are included in ezxappbase so we might be okay with only using new libs (and an updated Makefile) and not have to re-do much, if any, of the include files from samr7's dev-kit.

If the ezxnotification lib doesn't seem to be found in the a1200, try dropping it from the LIBS definition in the Makefile; at least it worked for my primiative test.

and finally, i am by far no expert but i found that 'vtable for XXX' errors can often be fixed by deleting the .moc file and forcing it to be remade during the Make procedure; just thought i'd pass that along...

and most of all, keep plugging away and thanks for sharing your work!!!

[blackhawk]

@eakrin
Thanks for sharing.

@eakrin, rpconnect
Have no ZApplication::setMainWidget(QWidget*) but QApplication::setMainWidget(QWidget*) . Maybe you can try:

int main(int argc, char** argv)
{
	ZApplication app(argc, argv);
	MyWidget *wp = new MyWidget(NULL);
	qApp->setMainWidget(wp);
	wp->show();
	return app.exec();
}

[rpconnect]

@blackhawk,eakrin
I had tried the qApp approach to settinng the main widget when trying to get qtopia examples to work in ezx, the app would run without errors but the problem was the app didn't seem to get "checked in" to the application manager and screen taps were fed to the background app which would take control and i'd loose control of the qApp. I should try it again however because I was trying to force a QApplication and ZApplication at the same time.

ZApplication::showMainWidget() seemed to do the same as setMainWidget and seems to behave nicely with the natively running apps.

[eakrin]

@blackhawk, rpconnect
thx for you suggestion. I try qApp->setMainWidget and app.showMainWidget. both work with ezx-crosstool + A1200 libraries. but still got an error ': undefined reference to 'vtable for MyWidget'

I does not understand much about what is moc file. coz i'm newbie in QT/Linux complier. but i have a little modiflied sam7 's helloworld. that sam7 use moc file and his Makefile gave me a huge binary. so i create a new project file by qmake. and create new Makefile by qmake too. from blackhawk's Texteditor.

so what can i do about :undefined reference to 'vtable for MyWidget' error?

my ezxcrosstool was build on cygwin in windowsXP SP2. everything work fine for A780 lib and app.

and here is an A1200 lib
