I have tried a lots of advice to help to set up the CDB debugger in Qt Creator but when using it that thing still takes ages to load up local variables.
My setup:
Windows 10 64-bit
Qt 5.6 (installed with sources)
Qt Creator 3.6.1
Microsoft Visual Studio 14 (2015) (both 32-bit and 64-bit compilers)
Windows SDK (for debugging tools = CDB)
The General tab in Options->Debugging lists auto-detected sources:
Source: Q:/qt5_workdir/w/s
Target: C:\Qt\5.6\Src
My symbols server and cache are set up in CDB Paths like this:
srv*http://msdl.microsoft.com/download/symbols
cache*C:\Qt\CDB-symbols-cache
On first run of the debugger it populates this directory with 70mb of (presumably downloaded) data but it does not seem to change afterwards on subsequent runs.
I suspect either the sources being loaded takes a long time (although I have a SSD) or that the CDB is re-downloading the symbols instead of using the cache. Any advice?
EDIT: As per request, result of .sympath command on my system:
Symbol search path is: srv*
Expanded Symbol search path is: cache*;SRV*https://msdl.microsoft.com/download/symbols

I had the same problem with QtCreator 4.12 which was solved by removing AppData\Roaming\QtProject\default.qws as suggested by Abstraction in the comments above.
I had the same issue with QtCreator 4.0.2 and VS 2015. Here is what I did.
Downloaded the microsoft symbol package from symbol packages
Copied it to a local folder(D:\Symbols)
In QtCreator , Tools->Options->Debugger->CDB Paths select "Insert Symbol Server" and select the local folder. Will look like the below screen.
I tried all the above and did not worked, however one thing worked: renaming the file default.qws
Usually it would take 10 seconds to load the debugger and it went to 10 minutes. Analyzing deeper I found out that the problem is with the breakpoints: if a breakpoint is on a file which is not part of the project, the debugger attempts to resolve the breakpoint for each loaded module/DLL, making the process incredibly slow.
The solution is to edit the file default.qws and remove those breakpoints which are set to files that don't exists anymore and you will get the speed as before.

I got GPS community edition, but it can't create GtkADA projects. So I cloned and built GtkADA using the GPR projects, but when I try to open a GtkADA example or start a new GtkADA project from GPS, I get the error:
unknown project file: "gtkada"
Edit:
Windows 10 x64, trying to "get into" Ada.
Edit2: Got farther.
I tried setting GPR_PROJECT_PATH to include the following paths:
drive:\gitrepos\gtkada\src
drive:\gitrepos\gtkada\src\lib
drive:\gitrepos\gtkada\src\lib\gtkada\relocatable
drive:\gitrepos\gtkada\src\obj
I am trying to run the base widget example, downloaded from https://www.adacore.com/code-samples for GtkAda.
Now I get:
file "gdk-gc.ads" not found
Indeed I cannot find this file in either the GNAT or GtkAda repo.
Edit2: I am still having difficulty.
Edit3: Other people on freenode#ada were saying the OpenGL part of GtkAda is broken, and many people simply disable it.
I had the same problem and couldn't find Gtkada (about gdk-gc.ads I can't help you).
Therefore I wrote the relative path from my project file to GtkAda.gpr
with "../../lib/gnat/gtkada"; -- on linux (I installed my gtkada into my gnat folder)
In your case, if you installed it on C:\GtkAda you should search for GtkAda.gpr, then copy paste its path.
(Not sure if absolute path works. You will maybe need to tell your project to search outside of its folders by using ".." until you are in C:, then paste your path.)
PS: Adacore provides a GtkAda installer for windows: https://www.adacore.com/download/more
Edit: On my windows, I simply used the installer then
with "gtkada" worked.
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.
Here is how I have configured my CDB Path in QtC
srv*http://msdl.microsoft.com/download/symbols
cache*R:\temp_KB\symbolcache
I have a Win 10 Windows Kit installed here
X:\Windows Kits\10\
When I debug in QtC I see the symbols cached on R (as expected), but also on
X:\Windows Kits\10\Debuggers\x86\sym
How can I avoid this, as it is consuming a lot of disk space? The sym directory gets pretty big.
Edit: One detail based on my comment below. It seems like only windows symbols are stored twice, the Qt library symbols I only see once in R:\temp_KB\symbolcache, but wkernelbase.pdb is stored twice (R:, ..sym).

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:

I installed Windows 10 (64bit). Since then, Isabelle HOL is no longer starting, even after a re-installation (which ran through smoothly). The error message is the following: "Startup Error: Error starting Java VM". This happens with the two versions I tested (2013-2 and 2015).
The jvm.dll which is specified in the configuration file, exists in the right folder. Additionally, I have installed Java SDK in newest version (8.51) in both, 32bit and 64bit.
Is there a known compatibility problem with Windows 10? Isabelle used to work with Windows 7 and 8.
Thank you for you help.
Update (150822)
From the developer's mailing list, there's a link to a test release:
NEWS: updated to jdk-8u60, with support for x86_64-windows
www4.in.tum.de/~wenzelm/test/Isabelle_21-Aug-2015
That's working different from Isabelle2015, in how it does some things with paths, so it might find the things it needs for Windows 10, or it may not. However, even if it works, there may be some incompatibilities with Isabelle2015 (in theorem proving).
Regardless, Isabelle only gets released 1 to 2 times a year, and I wouldn't expect anything special to be released for Windows 10 within 4 to 6 months. The links above, though, show that M.Wenzel can package together a test release, but he mainly operates on the user's mailing list.
In my batch file below, I set HOMEDRIVE and HOMEPATH, which you don't need if you want .isabelle to be in C:\user.
In this test release, those settings don't affect my home path. It also appears that USER_HOME is used, though my setting of USER_HOME doesn't make my batch file work for this test release.
Anyway, this test release has changed the way it works to discover things, and accomodates Windows even more, as shown by the new behaviour of the function File.platform_path.
It's working different enough, and requires enough changes, that I should stay with Isabelle2015, or I'll be out of sync with the official release.)
Original
(Zeroeth: Problems like this generally get hashed out on the mailing list, but I go ahead show you how I start Isabelle using a batch file, which I started doing before I had to start doing it.)
First, the Java that Isabelle uses is in this folder:
Isabelle2015\contrib\jdk\x86-cygwin\jre
Doing a normal Java install for Windows is not going to change which Java that Isabelle uses.
Below, I give you a batch file and bash file to start Isabelle/jEdit, which is an alternative to using Isabelle2015\Isabelle2015.exe.
For myself, what I've done is manually replace the 32-bit jre folder shown above with the jre in jre-8u45-windows-x64.tar.gz. (I renamed the old 32-bit folder. The most recent Java tar files can be found at the download page.)
Consequently, if I try to start up Isabelle with Isabelle2015.exe, I also get a popup that says, "Startup Error, Error starting Java VM", but starting Isabelle with the batch/bash combination works for me on Windows 8.1.
What I show you below may not fix your problem, but I guess Isabelle2015.exe has to get some info from the OS to work right, and maybe that's changed with Windows 10:
https://lists.cam.ac.uk/mailman/htdig/cl-isabelle-users/2014-December/msg00033.html
You put the batch and bash file below in the folder that you have or want your .isabelle folder. Change ISAHOME below to where your Isabelle distribution is. PATH needs the Cygwin bin in the path, and the path for isabelle, which I set in the batch file.
FILE: start-isabelle.bat
:: Isabelle2015.exe uses these directly. Setting HOME or USER_HOME doesn't work
set HOMEDRIVE=%~d0
set HOMEPATH=%~p0
:: Cygwin uses HOME, and this is how HOME is set in Cygwin-Terminal.bat
set HOME=%HOMEDRIVE%%HOMEPATH%
:: ADD PATHS: 'cygwin/bin' to start terminal, 'Isabelle2015/bin' for 'isabelle'
set ISAHOME=E:\E_2\d ev\Isabelle2015
set PATH=%PATH%;%ISAHOME%/contrib/cygwin/bin;%ISAHOME%/bin;
set CHERE_INVOKING=true
::MINTTY CONSOLE
start /MIN mintty.exe -i /Cygwin-Terminal.ico "%~dp0start-isabelle.bash"
:: REGULAR WINDOWS CONSOLE
::bash --login -i "%~dp0start-isabelle.bash"
FILE: start-isabelle.bash
#!/usr/bin/env bash
#
isabelle jedit -l HOL
With 64-bit Java, I can increase the size of the memory that Isabelle uses, by making this change in .isabelle\Isabelle2015\etc\settings:
JEDIT_JAVA_OPTIONS="-Xms1g -Xmx4g -Xss4m"
or
JEDIT_JAVA_OPTIONS="-Xms1024m -Xmx4096m -Xss4m"
With 32-bit Java, when I do that, Isabelle will start but then terminate.
