I want to learn YAML (and use it with C++) but i'm stuck trying to setup YAML-Cpp.
Let me explain what i've done so far.
I downloaded the source code (version 0.5.1)
Installed Cmake (for Windows)
Installed the Boost libraries (precompiled for Visual Studio 2010)
EDIT:
Built the solution and the INSTALL project
Then i got two folders on my C drive: include and lib
Then i moved it to another folder on my D drive (maybe it's relevant)
For testing, i created a project in V Express and tried to compile this:
#include "yaml-cpp/yaml.h"
int main()
{
YAML::Emitter out;
out << "Hello, World!";
std::cout << "Here's the output YAML:\n" << out.c_str();
return 0;
}
The new result:
d:\development\yamlcpp 0.51\include\yaml-cpp\node\ptr.h(10): fatal error C1083: Cannot open include file: 'boost/shared_ptr.hpp': No such file or directory
Can somebody please tell me what is the right way to build and configure this library?
It looks like you're not including the proper directory. In Visual Studio, there's an option for the "include directories" - make sure that the include directory for yaml-cpp is listed there.
marlon, you need to download boost-cpp (http://sourceforge.net/projects/boost/files/boost/1.58.0/), compile it and ensure to "include directory" in Visual Studio.

On one of our servers pgAgent service does not start with the message "ERROR: Couldn't register event handle" (see DBA Question). So I decided to compile the binary from the source, to further investigate the problem.
I installed Visual Studio Community 2017 Edition. I downloaded pgagent source code 3.4.0 and extracted to F:\pgbuild\pgAgent-3.4.0. I downloaded the wxWidgets 2.8, unpacked into F:\pgbuild\wxWidgets and built with visual studio 2017. I pointed out the these variables
wxMSW=F:\pgbuild\wxWidgets
WXWIN=F:\pgbuild\wxWidgets
PGDIR=C:\Program Files\PostgreSQL\9.6
WIX=C:\Program Files (x86)\WiX Toolset v3.11\
Then I tried to compile the pgAgent. Visual studio could recognize the CMake Project of it. When I compile the cmake project, I get an error:
Severity Code Description Project File Line Suppression State
Error C1083 Cannot open include file: '../../../lib/vc_lib/mswd/wx/setup.h': No such file or directory F:\pgbuild\pgAgent-3.4.0\CMakeLists.txt F:\pgbuild\wxWidgets\include\msvc\wx\setup.h 123
There are lots of urls around the problem on the net, but I cannot get a handle on it.
It looks to me that this code needs to be updated:
#ifdef wxSUFFIX
#define wxSETUPH_PATH \
wxCONCAT6(../../../lib/, wxLIB_SUBDIR, /, wxTOOLKIT_PREFIX, wxSUFFIX, /wx/setup.h)
#else // suffix is empty
#define wxSETUPH_PATH \
wxCONCAT5(../../../lib/, wxLIB_SUBDIR, /, wxTOOLKIT_PREFIX, /wx/setup.h)
#endif
I built wxWidgets using wx_vc15.sln in F:\pgbuild\wxWidgets\build\msw. I was trying to build pgAgent as CMake project, although the building instructions say that I need to use the GUI version of CMake.
I was following instructions to build pgAdmin, but now I am wondering whether I need to build pgAdmin (don't mix it up vs. pgAgent) at all.
Any suggestions how?
Update:
I installed CMake for Windows and created a solution file to F:/pgbuild/pgAgent-3.4.0/build. Got some errors lines back:
Then clicked on configure, then on gnerate. This created the visual studio project file. Tried to build it, got the error above (wx/setup.h: No such file or directory). The exact error is
Severity Code Description Project File Line Suppression State
Error C1083 Cannot open include file: '../../../lib/vc_dll/mswd/wx/setup.h': No such file or directory pgagent f:\pgbuild\wxwidgets\include\msvc\wx\setup.h 123
I'm trying to use a DLL with a Qt project in Visual Studio. Normally to use a DLL, it is put in the program's executable directory. However, after putting the DLL in just about every directory I could think of, it is still not being used by the program. Is there anything extra that I need to do aside from putting the DLL in the executable directory? Thanks.
The dll should be in the working directory of the executable. This is listed under the "Debugging" section of the Project Properties.
Almost all of the Qt plugin directories need to be in a specific folder next to the exe for it to be found (imageformats, platforms, etc).
Another way to find out if you are in the right directory is to add this line to your main.cpp:
#include <QDir>
#include <QDebug>
qDebug() << "Current Directory:" << QDir::currentPath();
Hope that helps.
PS also look at the order of dll search directories for windows. I'll post more later about it. https://msdn.microsoft.com/en-us/library/windows/desktop/ms682586(v=vs.85).aspx#search_order_for_desktop_applications
I am trying to get a C++ example to work which uses the OpenNI library for Kinect. I have setup my library as in the correct answer given here for a 32-bit version:
OpenNI 2 and Visual Studio 2012
However as soon as the code executes:
rc = OpenNI::initialize();
if (rc != openni::STATUS_OK)
throw runtime_error(string("Could not initialize OpenNI: ") + string(OpenNI::getExtendedError()));
I get the error:
Could not initialize OpenNI: Found no files matching (project path) OpenNI2\\Drivers\\*.dll'\n" const char *
The directory OpenNI2\Drivers\ does not exist, and should not in the project (vs2012) folder as far as I am aware?
I have no idea why it would be looking in the project path at all? The kinect divers are installed and openni is downloaded from:
http://structure.io/openni
I found the folder here:
C:\Program Files (x86)\OpenNI2\Samples\Bin
and copied it to my directory, which worked perfectly.
Install OpenNI2 from this link: https://structure.io/openni
Add this path as a Environment variable
C:\Program Files\OpenNI2\Samples\Bin
If you don't know how to add path as a variable follow the instruction of this link
https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/
Edit: Of course, immediately after working on it for an hour then posting here, I found the stupid mistake...
I'm getting compiler errors when trying to #include <d3dx9.h> in a project. I'm receiving "fatal error C1083: Cannot open include file: 'd3dx9.h': No such file or directory".
I do have the DirectX SDK installed (I also just tried reinstalling it to no avail).
In the Project Properties:
VC++ Directories are set to "$(DXSDK_DIR)Include;$(IncludePath)" and "$(DXSDK_DIR)Lib\x86;$(LibraryPath)" for Include and Library directories respectively for all configurations—and the environment variable %DXSDK_DIR% points to C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\ as expected.
C/C++ > General settings has $(DXSDK_DIR)include listed in the Additional Include Directories
Linker > Input > Additional Dependencies has d3dx9d.lib included for Debug and d3dx9.lib included for Release configuration.
I am able to successfully compile and run tutorial projects from the DirectX Sample Browser.
Visual Studio's Intellisense/autocomplete will find d3dx9.h and suggest type and function names that are within the file (and not included through anything else I'm #includeing) so it seems that Intellisense can find it.
Any suggestions on what I'm forgetting or what else to try?
Thanks
you forgot one thing:
Go to VC++ Directories -> Library Directories
add $(DXSDK_DIR)LIB\x86
apply.
Done. Hope this helps
You should make sure you have ALL paths sorounded by quotes (").
Instead of $(DXSDK_DIR)include you should have "$(DXSDK_DIR)include"
I didn't realize that one of the other projects in the solution was #includeing a file that was #includeing a file that was #includeing d3dx9.h and I hadn't added those paths to that project.
/facepalm
Find the file on your computer, and add it's folder to the properties of your project.
Assuming you have visual studio: Properties/C/C++/General/Additional Include Libraries.
I tried all of these suggestions and none worked.
Turns out the $(DXSDK_DIR) variable doesn't work if you install DirectX while Visual Studio is still running. The solution for me was to restart Visual Studio (+ adding the paths in the solutions listed above, of course).
I'm trying to build a basic Qt "Hello, world!" application inside Visual Studio.
I got the moc step to work (I think), but now I am at a loss as to how to fix this linker error:
1>moc_mainwindow.obj : error LNK2001: unresolved external symbol "public:
static struct QMetaObject const QMainWindow::staticMetaObject"
(?staticMetaObject#QMainWindow##2UQMetaObject##B)
I've done a lot of searching but I am at a loss.
Here are my include directories:
i:\Qt\4.6.3\include\QtCore;
i:\Qt\4.6.3\include\QtGui;
i:\Qt\4.6.3\include;
i:\Qt\4.6.3\include\ActiveQt;
reease;
.;
i:\Qt\4.6.3\mkspecs\win32-msvc2008
Here are the libraries I am linking against:
i:\Qt\4.6.3\lib\QtGui4.lib;
i:\Qt\4.6.3\lib\QtCore4.lib;
gdi32.lib;
comdlg32.lib;
oleaut32.lib;
imm32.lib;
winmm.lib;
winspool.lib;
ws2_32.lib;
ole32.lib;
user32.lib;
advapi32.lib;
libpng.lib;
msimg32.lib;
shell32.lib;
kernel32.lib;
uuid.lib;
Does anyone have any ideas?
qmake will generate the moc voodoo from the header file in .pro file. As you aren't using qmake, by the sound of it, but a native visual studio project, this is probably the cause of the problem.
If you use qmake to generate your visual studio project all your problems will go away and life will be sweet. Probably!
I am using the open 2010.05; obviously you want to substitute the correct path for your version.
set up the environment
start 2010 command environment from the start menu
-set include=%include%;C:\Qt\2010.05\qt\include
-set lib=%lib%;C:\Qt\2010.05\qt\lib
-set path=%path%;C:\Qt\2010.05\qt\bin
-set QMAKESPEC=win32-msvc2010
write code, create files etc
generate the initial pro and makefile and fire up VS
-qmake -tp vc
-qmake
you should now have a makefile - check that it works by running:
-nmake
now launch visual studio
-VCExpress.exe /useenv
-XXX.vcxproj can now be opened
If this doesn't work you may need to build qt at against visual studio. This is very straightforward - go to the qt directory (from within the visual studio express command window) and type:
configure.exe -platform win32-msvc2010 -no-webkit -no-phonon -no-phonon-backend -no-script -no-scripttools -no-multimedia -no-qt3support -fast
You cannot install the Qt VS plugin on the Express edition of VC++. Assuming you got the moc to compile, you also need to make sure you're including the appropriate libraries (*.lib files) at link time. This goes under Project properties > Linker > Input > Additional Dependencies.
You will need qtcore4.lib at a minimum.
Also make sure the Qt library path is in your library search path. On my computer it's c:\qt\4.6.2\lib.
I was able to get QT to work with Visual C++ Express 2010 using http://rajorshi.net/blog/2009/01/using-qt-with-msvc-express-2008/ and http://portfolio.delinkx.com/files/Qt.pdf as guides. Just in case anyone still is having problems.
Have you create the visual studio project using qmake first? The problem seems to be the moc compilation. Do you have qt plug-in installed and the qt path in enviromental variables? Can you add you hello world code so I can have a look at it?
You need to add commands to generate QT metaclasses, then also include the generated files in your project as c++ code.
Generating the QT metaclasses:
First, add your QT bin path into the Executable Directory. (This is in Configuration Properties > VC++ Directories)
Add your Header files that contain Q_OBJECT macros to the project.
Multi-select your header files, then right click on a header file, click Properties.
Change "Item Type" from "C/C++ Header" to "Custom Build Tool".
Set Command line to this: moc.exe "%(FullPath)" > "$(ProjectDir)MetaObjects\moc_%(Filename).cpp"
Set Description to this: QT: Generate $(ProjectDir)MetaObjects\moc_%(Filename).cpp (optional)
Set Outputs to this: $(ProjectDir)MetaObjects\moc_%(Filename).cpp
Run Build just to make it generate the metaobject code
Add the generated C++ files from the Project Directory Metaobjects folder into your project
