Moved from here, because it's about compiling software.
My original problem: I want to play Super Mario Galaxy 2 with another player. But whatever keys I assign to move the cursor, it instead moves it all the way to the corner (or edge) of the screen. Linux theoretically has the ability to have multiple cursors (at least the display system "X" allows it), but from a research it looks like I would have to make major changes to the system to actually use it. And even then I doubt that Dolphin would support it.
My current problem: Relative motion of a cursor from keys is present in the current betas of Dolphin, but I can't get it installed. There are no regular installers for it, instead there are source downloads and this tutorial.
I installed the dependencies, downloaded the beta, created and entered the "Build" directory, but when I try cmake .., I get this output:

To be safe I installed all five of these packages. I also installed version 5.10 of Qt5-default from here, later also 5.11. I also installed qtbase5-private-dev, libreadline-dev and tried to install libpolarssl-dev, but the page gave error messages for all four servers (the Taiwanian one just loads forever, the others give 404). Then I tried the Qt installer and selected the latest stable version (5.11 I think) once and 5.9 once.
None of these steps helped, I still get the same output as at the beginning.

Many thanks to the user dugan on linuxquestions.org! He solved my problem here.
I just had to install Qt from a different source (I used the Qt installer, as mentioned in the question), to have a different version of it in another location. The reason for that is that many programs on Debian rely on an earlier version of Qt, so just updating it would break a lot, that's also why Synaptic&Co. don't update it.
Then I had to add the binary to the PATH variable, like so:
export PATH=/home/fabian/Qt/5.11.2/gcc_64/bin:$PATH
Then I was able to just install Dolphin beta regularly, like the tutorial says it.

I just installed OpenBSD 6.9 to study how it works.
I wanted to get the most minimal config possible, because I want to use it as a server.
During instalation I chose the option to not install Xserver, but I still have the /usr/X11R6 and /etc/X11 directories with X config and commands like startx. The only difference is that now, startx doesn't work. I tried installing on VirtualBox and on bare metal and both were the same.
What do I have to do in order to completely remove X from OpenBSD? And why is it still being installed in my machine even if I explicitly write "no" when prompted during installation?
My system:
OpenBSD 6.9
Intel Pentium G5400
Nvidia 1050 ti.
OpenBSD installation uses different file sets => see OpenBSD FAQ / File Sets
X11 installation is split into 4 file sets :
xbase71.tgz : Base libraries and utilities for X11 (requires xshare71.tgz)
xfont71.tgz : Fonts used by X11
xserv71.tgz : X11's X servers
xshare71.tgz : X11's man pages, locale settings and includes
During installation, you chose not to install xserv71.tgz (X servers) but you still have installed xbase71.tgz (startx command and others directories).
If you want to completely remove X from OpenBSD, during installation, remove every file set for X. But you should keep xbase71.tgz because some programs needs it to run correctly even if it's a non-X program.
I'm not a OpenBSD developer, so I cannot give a clear answer. But some specific packages which you can add with the package command from OpenBSD (pkg_add), needs some X libraries or binaries.
As example when you want to add vim for the first time, then you have eight flavors:
$ pkg_info -d vim-8.2.3456-no_x11
Information for inst:vim-8.2.3456-no_x11
[REMOVED]
Flavors:
gtk2 - build using the Gtk+2 toolkit
gtk3 - build using the Gtk+3 toolkit (default)
no_x11 - build without X11 support
lua - build with Lua support
perl - build with Perl support
python - build with Python support
python3 - build with Python3 support
ruby - build with Ruby support
It's depends on the packages what you need. Also when you want install something from the port collections.
You can try the quick and dirty way and simple remove your mentioned directories. But I could be possible that some programs from the base system no longer works, because of missing dependencies.
On its website OpenFlipper says it can be compiled in three steps as:
cd build
cmake ..
make # or, even better, make -j8
However I get an error saying Qt is unable to be found at the cmake step and that I should specify a QT5_INSTALL_PATH. However even if I do this OpenFlipper is still issuing the same complaint!
You are not supposed to specify where Qt is installed in the QT5_INSTALLED_DIR but prior to that as environment variable in your terminal:
# assuming Qt was installed in your home directory, as is default
export CMAKE_PREFIX_PATH=~/Qt5.7.0/5.7/gcc_64/
# note that you now have to call cmake etc from that process
Compiling and running it after that you might get errors telling you GL_ARB_vertex_buffer_object is not present, even if your glxinfo | grep ARB_vertex_buffer is telling you it is.* Clicking "Ignore" results in a crash. To mitigate this, you have to manually change (4,3) to (3,0) in
OpenFlipper/widgets/coreWidget/CoreWidget.cc
If you still experience errors, try deleting your cmake cache, this is accomplished by using cmake-gui (was in the package cmake-qt-gui for me) and hitting "Delete Cache"
(optional) remove the very annoying warning message you get at every start of OpenFlipper by removing the line concerning "renderers shipped" in
OpenFlipper/Core/Core.cc
*: My teaching assistant told me that there is a bug in Qt (<5.9) that forces OpenFlipper to use the OpenGL Compatibility Profile. Additionally Intel and AMD drivers hand back an OpenGL 3.0 Core Context when asked for an OpenGL 4.3 Compatibility Context (my TA described this behavior as a "bug", I'm not so sure about this), leading to a crash in Qt. So this should be resolved in Qt 5.9 (not out yet). This seems to affect also mainly integrated graphics, so one could try using a dedicated GPU.
I recently upgraded to Architect version 0.9.7 on my Win 7 machine. However, after starting Architect, the RJ console wouldn't launch and I got the error message:
‘Launching the R Console was cancelled, because It seems starting the R engine failed.”
Please make sure that R package 'rj' (2.0 or compatible) is installed and
that the R library paths are set correctly for the R environment
configuration 'Embedded R Server'.
I installed the packages ‘rj’ and ‘rj.gd’ through the RTerm run console (which does happen to work) within Architect using the command suggested on www.walware.de:
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-2.0")
Then, I restarted windows, and restarted Architect. Same error message. I zoomed in on the details of the error message and noticed the following line:
SEVERE: Path to rj package not found. Use R_LIBS or java property
'de.walware.rj.rpkg.path' to specify the location.
So I opened an RTerm run console to check whether any of my .libPaths() locations contains the directories ‘rj’ or ‘rj.gd’. Oddly enough, they do. My first .libPaths path contains both packages. So that doesn’t seem to be the reason.
How could this be fixed?
I received prompt and helpful feedback from Open Analytics (thanks!), who informed me that the problem is due to changes in Java 8. With Java 7, Architect works fine. The next release of Architect will incorporate the changes in Java 8.
In order to get it work with Java 7, enforce the use of a specific Java Runtime, by using the -vm argument in the architect.ini file as follows:
-vm
C:\Program Files\Java\jre7\bin\javaw.exe
(mind the line break, which is required)
This is particularly useful if you have several Java versions on your system where the default Java is not suitable for use with Architect. The architect.ini file is found directly at the top level of the installation folder of Architect. You can find out where this is by looking at the Properties of the Architect shortcut on your desktop.
N.B. the -vm argument should be put before the -vmargs argument otherwise it is simply ignored!
N.B. examples of -vm specification on GNU/Linux and Mac OS X:

In the code file i have to link just one library (from gi.repository import Gtk).
But when i run it it replies me:
Gtk-WARNING **: Unknown property: GtkTextView.input-purpose
ERROR --file: collega_GUI --riga: 160, 'Grid' object has no attribute
'get_child_at'
So i tried to find missing libraries:
$ dpkg -l libgtk[0-9]* | grep ^i
ii libgtk2.0-0 2.24.10-0ubuntu6 GTK+ graphical user interface library
ii libgtk2.0-bin 2.24.10-0ubuntu6 programs for the GTK+ graphical user interface library
ii libgtk2.0-common 2.24.10-0ubuntu6 common files for the GTK+ graphical user interface library
ii libgtk2.0-dev 2.24.10-0ubuntu6 development files for the GTK+ library
and Grid object needs gtk3+, so let's install it:
$ sudo apt-get install libgtk-3-0 libgtk-3-common libgtk-3-dev libgtk-3-doc
0 updated, 0 installed, 0 removed and 0 not upgraded
So it's all fine with libraries and:
gtk-grid-get-child-at exists
GtkTextView--input-purpose exists
that "input-purpose" problem is strange, because on the previous OS (ubuntu 13.10, now i'm on 12.04) i didn't get that problem.
The UI is built by Glade, but i never get that error previously: on the same project files, but on a different OS version.
I still think i need to install some libraries.
EDIT :: ged_child_at function call
griglia = self.__builder.get_object('grid3')
for i in range(0, 3):
area = griglia.get_child_at(i, 0)
self.__builder.get_object(Gtk.Buildable.get_name(area)).connect("draw", self.draw)
The tag Since 3.6 for that property which means in Gtk+ 3.4 (which is the default of ubuntu 12.04 if I recall correctly).
So you either work around it or you go the thorny way of upgrading to Gtk+ 3.6 - which I - with all respect - do strongly disrecommend - especially since Unity needs various patches being incorporated into Gtk+ to work at all.
I just checked in gtk+-3.10.x the python bindings are fine and include get_child_at(..).
This question contains an answer that in fact this is a bug in the python bindings of gtk+ 3.4.
Solutions: Backport the git commit that fixes this (should be very tiny git commit) recompile/create deb package (significant knowledge required).
An alternate route would be to locally fix the binding specification and recreate the python introspection bindings locally - not sure if that is possible though - never did that.
I have an library (flam3) that depends on a few utility libraries from unix (xml2, jpeg, png, z) and I am trying to make an application on Lion that uses it. I am building with the latest Xcode and when I try to link with the libraries from fink, macports, and homebrew I get the same error:
ld: warning: ignoring file /opt/local/lib/libxml2.a, file was built
for archive which is not the architecture being linked (i386)
and the libraries look different from ones that work:
bash-3.2$ file /sw/lib/libxml2.a
/sw/lib/libxml2.a: current ar archive random library
by comparision
bash-3.2$ file ~/Documents/FLAM3/libflam3.a
/Users/spot/Documents/FLAM3/libflam3.a: Mach-O universal binary with 2
architectures
/Users/spot/Documents/FLAM3/libflam3.a (for architecture x86_64):
current ar archive random library
/Users/spot/Documents/FLAM3/libflam3.a (for architecture i386):
current ar archive random library
that's the library that I compiled with Xcode.
Is there any way to get Xcode to accept this library? Is there any way to get fink/macports/homebrew to generate a library that works with Xcode? Seems like I am "doing it wrong" as these projects would all be useless if everyone had this problem.... but I don't feel like I've done anything unusual. Help?
The problem is that your libxml2.a is not built as "Universal binary". I.e. it doesn't contain all necessary architectures (In your case I believe it is i386). You need to ask fink, macports, or homebrew to build/download/install library with all necessary platforms. I know that macports has such flag (I don't remember how it's called).
The "file" command list all available architectures for .a file only when the file is trully universal (contains two or more of ppc, i386, x86_64), otherwise it only shows the vanilla "ar archive..." message. That confirms your libxml2.a has only one architecture.
The problem is not in Xcode or Lion. Possibly the default link architecture on Lion changed.
