I want to enable touchscreen in QT, so I gave:
ui->pushButton->setsetAttribute(Qt::WA_AcceptTouchEvents,true);
but it shows the following error:
error: no matching function for call to 'QPushButton::setAttribute(bool)'
ui->pushButton->setAttribute((Qt::WA_AcceptTouchEvents,true));
^
Remove the superfluous parentheses:
ui->pushButton->setAttribute(Qt::WA_AcceptTouchEvents,true);
vs.
ui->pushButton->setAttribute((Qt::WA_AcceptTouchEvents,true));

I would like to play AOM on gameranger on my linux mint 17.3 rosa.
I can play AOM with wine but i cant open gameranger. everytime I try this error pops up:
gameranger has encountered an unexpected error and must quit.
this error has been logged automatically.
this should be the log:

I've wandered around the internet, trying this trying that. Nothing works.

here is the solution, look down the page.
I'm trying to install OpenCV-2.4.9 on CentOS 7 (PC) however getting error after 16% when running "make" command. I leave default configuration for OpenCV.
make
...

It seems that the define HAVE_CAMV4L has the value 1, if you look in the file modules/highgui/src/cap_v4l.cpp looking for the structure definition at the row 306. If the compilation fails at that point this means that the video4linux development configuration is corrupted.
Using google I have found that the OpenCV Bug #1357 is described as follow:
CHECK_INCLUDE_FILE(linux/videodev.h HAVE_CAMV4L) succeeds even though linux/videodev.h doesn't exist on the system. (Bug #1357)
http://code.opencv.org/issues/1357
Anyway the solution is described at the same URL for "HAVE_CAMV4L gets set incorrectly": "Setting it to FALSE in CMakeLists.txt fixes the problem".
I tried to play with overtone on ubuntu, but I can't eval some of overtone's codes in Vim.
:Eval works for the clojure code; I tried it in vim (a clj file in the lein project directory), ex: (+ 1 2 3) => :Eval => appeared on the bottom of the vim window => 6, so it's ok.
But, for example, I tried:
(demo(sin-osc)) => :Eval ;(:Require don't change nothing)
It returned:
java.lang.RuntimeException: Unable to resolve symbol: demo in this context, comp
iling:(NO_SOURCE_PATH:1:1)
So here's what I do:
jack is started
lein repl is started in the lein project (deps is ok)
in the first terminal where there is lein I start overtone (use 'overtone.live), here is the log; I've got 2 errors:
user=> (use 'overtone.live)
--> Loading Overtone...
--> Booting internal SuperCollider server...
* ERROR: dlsym load err '/home/axxon/workspace/overtone/tutorial/native/linux/x86_64/libscsynth.so: undefined symbol: load'

here, in this window I tried (demo(sin-osc)). it works; I can hear it.
Great, but now I want to script with Vim, so I created a new file (mytest.clj) in the lein project directory (/overtone/tutorial), I opened it with Vim (in another window)
in this blank file, I wrote the same thing as I said before, (demo(sin-osc)) and tried to eval with first, :Require, it returned this:
(clojure.core/require 'user :reload)
java.io.FileNotFoundException: Could not locate user__init.class or user.clj on
classpath:
with Eval, it doesn't work either.
Thanks for your help because I really want to use overtone!
Ps: my vim bundles:
Bundle 'guns/vim-clojure-static'
Bundle 'tpope/vim-fireplace'
Bundle 'tpope/vim-classpath'
Edit: I forgot to use a correct namespace, and in overtone's google group, i seen that mytest.clj must be in the src directory of the project. I tried this code with :Require (i stopped overtone in the first window where i started lein):
(ns tutorial.foo
(:use [overtone.live]))
(definst saw-wave [freq 440 attack 0.01 sustain 0.4 release 0.1 vol 0.4]
(* (env-gen (lin-env attack sustain release) 1 1 0 1 FREE) (saw freq) vol))
(saw-wave)
, but it returned:
(clojure.core/require 'tutorial.foo :reload)

I was having the same problem. It turned out that the vim fireplace plugin was not connected to my bash repl session. I manually established the connection and everything worked just fine afterwards.
At the top of your lein session you should see the details about what port the repl session is running on
nREPL server started on port 35182 on host 127.0.0.1
So then you can connect vim-fireplace to that repl session by using
:Connect nrepl://localhost:35182
The reason why you can still evaluate code like (+ 1 2 3) even when vim-fireplace is not connected to the remote repl session is because vim-classpath will make it fall back to just spawning a new clojure runtime instance to evaluate that code. Once the fireplace repl connection is working you should notice that evaluating code becomes a lot faster since it doesn't need to load clojure from scratch.
Make sure that you use overtone.live in the namespace declaration of the file you are editing in vim, and that the REPL is running in a separate terminal instance. From vim, save the file (:w) and move your cursor into the ns declaration. Then hit gf to open the file for the namespace. Type cpR or :Require! and then cpp or :Eval the function you were trying to run. Hopefully this will work for you! Best of luck.
I use the radrails ide for running watir tests. I have the following command:
ie.link(:text, "Task").click
ie1=Watir::IE.attach(:title, 'Task')
Using the above command I get the error:
E:/Ruby193/lib/ruby/gems/1.9.1/gems/watir-classic-3.0.0/lib/watir-classic/ie-class.rb:760:in `rescue in attach_browser_window': Unable to locate a window with title of Task (Watir::Exception::NoMatchingWindowFoundException)

The Ruby version is 1.9.3, ie 8, html code of the page I want to attach -
<a id="sdmenu141" class="nodeSel" onclick="javascript: dmenu.s(141);" target="_self" href="javascript:configuredWindowOpen('../ROU/Mterou004p0001Form.do?resetFilter_action=','_blank','regular');">Task</a>
after clicking on the link in the first line of code it opens new browser window.
Also today I got a new error:
E:/Ruby193/lib/ruby/gems/1.9.1/gems/watir-classic-3.0.0/lib/watir-classic/ie-class.rb:374:in method_missing': (in OLE method navigate': )

Well, the error message says it all: Unable to locate a window with title of Task.
To resolve this issue use Watir Web Driver.
I want to use atomic API, and I include . I don't know how to use it! Thank you!
I have it in /usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/atomic.h.
I also add -I/usr/src/linux-headers-2.6.28-11/arch/x86/include/ and -I/usr/src/linux-headers-2.6.28-11/include.
Some other errors is produced because of -DCONFIG_X86_32 and -D__KERNEL__ macro undefined.
Then I define the two macros,
some errors occurred:
/usr/src/linux-headers-2.6.28-11/include/linux/cpumask.h:600:37: error: "and" may not appear in macro parameter list

My system is ubuntu 9.04 running on Virtualbox3.0.
If you know where the file is on your HD, then you say gcc mySource.c -I/path/to/atomic
note that this assumes you include "atomic" directly. and not "some/path/atmomic.h"
