If you are launching an additional process, it might be linking again with GUI libraries, and the system might be trying to make another GUI of it. This is just a guess, but it makes some sense given the Wayland assertion that you are having. Is it completely gone if you don't launch a process? Possible solutions might be cleaning the environment where you launch the process, launching it some other way (it's been a while since I last used QProcess, but I recall different ways), or just not launching it at all. If you want to get the output of df, think to yourself how does df get that information in the first place?.

A (philosophical?) problem is that from Qt's perspective, Sailfish is not really an OS - that would be Linux - but merely a distro. Once you start down this path of Q_OS_..., one could argue for Q_OS_DEBIAN and Q_OS_REDHAT, etc. What is (from a developer's perspective) special about SailfishOS is how it is different from other Linuxes, hence the package detection being the right way. Yes, I've given it some thought, and is not an easy to draw line. There is certainly a distinction, but one could defend that such detection has to be done at runtime instead. For example, a dialog in KDE has a different OK/Cancel ordering than in GNOME (and different look, etc.). The binary might be the same, but the application chooses behaviour at runtime. I thought that Sailfish might be a different than a simple environment where the app might be executed in that it has some platform specific libraries (libsailfishapp, booster). Also, the fact that Blackberry 10 is treated different than QNX, so they have the boilerplate set up.

[SailfishDevel] SailfishOS as an OS/platform in Qt
Hi. I've asked this a couple of times on IRC, but I haven't found a fully satisfying answer. I want to see SailfishOS as any other OS/platform is featured in Qt: by having some qmake support to detect wheter I'm compiling for SailfishOS or not. Once that is done, having a Q_OS_SAILFISH preprocessor macro that can also choose different paths in C++ and adding support in QFileSelector is trivial. The big question is: do you want such thing in Qt? If yes, I would gladly do it myself, since I have some time available and I'm looking for ways to contribute to Qt, learn, etc. Rationale: Right now everyone is baking its own way, with varying degrees of success. ;-) I looked at it a year ago when I started writing my Sailfish application, and I was pointed to puzzle-master's sources, where a simple packagesExist(sailfishapp) did the trick... or so I thought. Since I wasn't testing the non-Sailfish branch much, I didn't realize Creator always returns true on this condition (by design: not allowed to fork a process when parsing .pro files). Seems a petty complaint (who cares about Creator that much? it works for qmake just fine), but with harbour requiring a harbour- prefix in the name of the executable, Creator might not even be able to start the application because it doesn't find it if you use a different value for TARGET. Lately I've been finding time for the app again and I finally noticed the problem, so I asked on IRC again. I was pointed at other application, and the check used was even worse. :-) Then I searched a bit in the branch of the mer-qt/qtbase repo. I see you don't use any mkspec for SailfishOS or Jolla, right? That's where I thought you might have it, and where I think it could be. Blackberry sets there the QMAKE_PLATFORM and Q_OS_BLACKBERRY. Yes, yes. I know there is a solution: pass a parameter to the qmake invocation. Store the invocation flag on the RPM packaging for final deployment, and maybe a .pro.shared file for development. That's what Puzzle Master has now too. Still I think there is some value in having this sorted out in a more general way, specially given that you'll want people to also distinguish a build for the Jolla phone or the Jolla tablet.

Re: [SailfishDevel] Qt 5.2 in devel

For our Qt 5.2 branch, we still have a lot of patches, but all of these patches were upstreamed to 5.3 and 5.4 before they were back-ported into our 5.2 branch, so we're converging rather than diverging. Awesome, that's what I wanted to read. :-) It is a valid point, and do we want to stay fairly close to the latest released Qt, preferably without patches. But since we also have a platform on top of Qt, there is some latency in getting there. Yes, I completely understand, it also happened to me. I have a couple of projects at work where we use 5.2, and I had to override Qt's behaviour (for simple stuff like logging to the journal and configuring logging categories in a file) using the public API. That was simple, but the cool, mantainable way is of course adding the feature in Qt itself so all applications have it automatically. We didn't had the time, but luckily Robin and Kai added those exact two features to 5.3, so we can get rid of our custom code. Hope that answers your question. Definetely. And let us know if there is some way to help with these kind of things.

[SailfishDevel] D-Bus viewer touch
Hi. During this holidays I did an attempt at a port to Silica and SailfishOS the qdbusviewer. Is a really nice tool for learning how your system works, specially on a platform like this. By this time I would have expected to have something a bit more meaningful to announce, but the holidays are over and I will have less time the next weeks... I wanted the code to be open since the beginning, but you know the usual problem with open projects: it doesn't cause a splash when you got to some cool point because everybody knew it since a long time ago. Anyway, here is the source: https://bitbucket.org/suy/qdbusviewer-touch I'm not publishing binaries at this point, since I've found at least one bug, and I'm not fully sure I got the dynamic object creation (for the model of the pages) right, so it might be a leak. I'll try to make it at least as featureful as the qdbusviewer on the desktop, but meanwhile you have read only capabilities to satisfy some curiosity. Please don't look much at the inside. The design needs a lot of cleanup once I learn how to do it properly. :) Screenshots: http://darkshines.net/pub/dbusviewer-touch1.png http://darkshines.net/pub/dbusviewer-touch2.png Oh, and the original qdbusviewer on the phone: http://darkshines.net/pub/20140106173406.png Not very finger friendly. ;-) -- Alex (a.k.a. suy) | GPG ID 0x0B8B0BC2 http://barnacity.net/ | http://disperso.net ___ SailfishOS.org Devel mailing list

ALL projects seem to be different from each other and use different conventions... Because not all projects are the same, and because not all projects are developed by the same people. it would not be better to use all the same convention and having QtC to check what's missing in .pro and .yaml for us?). That's even harder, and worse. You could define some high level project that would generate a .pro file, but once you generate the project file, you would end up needing to modify the .pro anyways. And you would need extra documentation for the added layer. I suggest you that you try to be patient, and don't try to learn all it at the same time. QMake is not awesome, and is not the best documented thing in the world, but is manageable, and for the use case of the majority of Sailfish developers, is not harder that doing the application itself. The problem is that one very quickly wants to do that, and at the same time do the packaging, which is another step, and is not necessarily well documented (IMHO) compared to qmake. If you can, try making your application work on the desktop as well. At least make it compile and install, so you can try simply if all files get copied to where you want. Then you can start blaming RPM or the packaging infrastructure if something doesn't work. Otherwise, without good knowledge of any of the two sides (building and packaging), you are shooting with your eyes closed. -- Alex (a.k.a. suy) | GPG ID 0x0B8B0BC2 http://barnacity.net/ | http://disperso.net ___ SailfishOS.org Devel mailing list

If you started with the suggested template, you have a project configured for creating one executable alone.

Copy the library in its subdirectory, and build it with a library template (check the qmake docs). All that is the normal procedure. Now make the library install in the path allowed by harbour, and use QMAKE_RPATHDIR to add that additional directory on the executable. That's more or less it.
