Cascades for Playbook ?

**jeroen_13** · 02-10-2013, 03:39 AM

Hi, i saw a topic about cascades for the playbook, but there wasn't a real how-to description. The topic is dead, so maybe people here know; how can I run Cascades on the playbook ?

How do I have to package the apps ? I know that you manually have to add all the libs

I'd be interested to see if anyone else has got it working. I can get an app to compile but when I run it I just get a bunch of error messages.

Code:

I don't think it's going to be possible to do, there are some changes to some core libraries that I'm guessing will stop it from working. Although it is interesting to see that the code still refers to the device as the Blackberry Colt.

could you contact the dev of the Pacemaker app? it was supposed to be 100% cascades

**big bb** · 02-14-2013, 08:17 AM

Here is a post about it /dev/alopix: HowTo: Use BlackBerry 10 Cascades UI framework on PlayBook.
I have not had time to test if it works.

NVM i had that bookmarked from before, I just was reading the comments that say it does not work anymore.

Even though I hate bump posts I'm going to bump this thread to make sure that it remains at the top of the threads list. I'm really interested to see if other people have attempted to get this running with the latest SDKs or if this is still possible if you have older SDKs sitting around. It's unfortunate that this thread got moved to an obscure forum at the bottom of the forums page.

How did you compiled it ? Whick SDK did you used an what command line codes ?

Could you please share it ?

make sure it stays at the top of the list

I compiled in Momentics targeting platform 2.1 and extracted the cascades libraries from the BB10 Gold SDK. The code is more or less just the default template for cascades projects in the gold SDKs version of Momentics with Application::addLibraryPath("app/native/lib"); added as the first line of code in the main method (I actually think I pulled it out of the AlmostTI project).

I archived the projects directory and uploaded it here: TestCascades.zip

To keep the file size down I didn't include anything that I extracted from the BB10 SDK. You will need to copy the bb folder from target_10_0_9_1673/qnx6/usr/include to the include folder in the project as well as the following libraries from either target_10_0_9_1673/qnx6/[x86 or armle-v7]/usr/lib or target_10_0_9_1673/qnx6/[x86 or armle-v7]/lib to the libs folder.

libasound.so.2, libaudio_manager.so.1, libbb.so, libbbcascades.so, libbbplatformqmlplugin_1.so, libbbsystem.so, libbps.so, libcamapi.so.1, libcertmgr_client.so.1, libcontext.so, libgoogleurl.so, libgrskia.so, libharfbuzz.so.0, libharfbuzzng.so.0, libhuapi.so.5, libicudata.so.49, libicui18n.so.49, libicuuc.so.49, libimfclient.so.1, libinput_client.so.1, libiTypes.so.1, libmd.so.1, libnfc.so, libnfc_bps.so, libpps.so.1, libppscache.so.1, libproxyinfo.so.1, libQtCore.so, libQtDeclarative.so, libQtGui.so, libQtNetwork.so, libQtOpenGL.so, libQtScript.so, libQtScriptTools.so, libQtSql.so, libQtSvg.so, libQtXml.so, libQtXmlPatterns.so, libsbgse56.so.0, libscreen.so, libscreen.so.1, libslog2.so, libstrpattern.so, libwebkit.so, libwebkitplatform.so, and libwebview.so.

I also think I did something funny with the folder setup so this is missing from the uploaded archive and will need to be added to a c file:

Code:

#include <time.h>
#include <stdlib.h>
#include <string.h>
#include <dirent.h>
#include <sys/cdefs.h>
#include <sys/types.h>
#include <stdint.h>

time_t timegm(struct tm * tm)
{
	time_t ret = 0;
	char *tz;
	tz = getenv("TZ");
	setenv("TZ", "", 1);
	tzset();
	ret = mktime(tm);
	if (tz)
		setenv("TZ", tz, 1);
	else
		unsetenv("TZ");
	tzset();
	return ret;
}

size_t strnlen(const char* s, size_t maxlen)
{
	size_t len = 0;
	while (s[len] != '\0' && maxlen > 0)
	{
		if (s[++len] == '\0' || --maxlen == 0)
			return len;
		if (s[++len] == '\0' || --maxlen == 0)
			return len;
		if (s[++len] == '\0' || --maxlen == 0)
			return len;
		++len;
		--maxlen;
	}
	return len;
}

int _readdir_r(DIR *dirp, struct dirent *entry, struct dirent **result)
{
	return readdir_r(dirp, entry, result);
}

int inotify_init(void)
{
	return -1;
}

int inotify_add_watch(int fd, const char * path, uint32_t mask)
{
	return -1;
}

int inotify_rm_watch(int fd, int32_t wd)
{
	return -1;
}

to which file do i need to add it ? and how do i have to name it ?

**travisredpath** · 02-16-2013, 11:04 AM

Add it to a c file (ex. libc.c) anywhere in the source folder.

your method didn't worked for me...

i managed to deploy/edit an other app (xSachas' sample)
i only can edit 1 .qml file because i dont have the source code.
the manifest only shows 1 qml file

**travisredpath** · 02-21-2013, 11:22 PM

What problems did you find? You will have to make sure that the build is not accidentally targeting the OS 2.1 version of the libraries that need to be updated (ie. that exist in the lib folder).

I'd be interested in more details about xSacha's example.
