I have been trying to get GTK 3.0 to work, and have followed all the steps here
How to configure gtk on Visual studio 2010
And changing to 3.0 where needed to get GTK to work, and it seems to have loaded everything it needs in order to compile, but it gives me the error
Error 3 error LNK1104: cannot open file 'gtk-3.lib'
Whenever I try to run the program.
I am using visual studios 2012, but this was the only place i found anything about getting GTK to run on any visual studios.
Here is the code I am using:
#include <gtk-3.0\gtk\gtk.h>
int main(int argc, char* argv[])
{
gtk_init(&argc, &argv);
GtkWidget* window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
//gtk_widget_get_preferred_size(window, 300, 200);
g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL);
gtk_window_set_title(GTK_WINDOW(window), "GTK+ with VS2010");
gtk_widget_show(window);
gtk_main();
return 0;
}
I commented out the gtk_widget_get_prefered_size call because it is irrelevant to the problem
any suggestions? I've looked in several places but none came up with clear answers.
The library gtk-3.lib does not exist. In fact, the library reference is not required to build your GTK 3 application. The pkg-config helper doesn't seem to generate the correct linker flags needed to link your application.
Just add in your Additional Options area all the existing libraries found in your GTK package (\gtk3\lib). The lib files for my bundle (gtk+-bundle_3.6.4-20130921) were as follows:
atk-1.0.lib cairo.lib fontconfig.lib gailutil.lib gdk-win32-3.0.lib gdk_pixbuf-2.0.lib gio-2.0.lib glib-2.0.lib gmodule-2.0.lib gobject-2.0.lib gthread-2.0.lib gtk-win32-3.0.lib pango-1.0.lib pangocairo-1.0.lib pangoft2-1.0.lib pangowin32-1.0.lib
(or you can go to your library path via a command prompt and enter dir *.lib /B)
Don't forget to include the /ENTRY:mainCRTStartup flag mention in the initial answer you started with.
you may have to edit your project settings or use a pragma comment to link with your gtk library:
#pragma comment(lib, "gtk-3")//if the libray is on your project's path
#define PATH "C:\\example\\"
#pragma comment(lib, PATH"gtk-3")//if the library is on PATH

I'm looking to build a host program calling OpenCL code running on my GPU device. The cl source has the following form:
#include "skip_mwc.cl"
typedef struct{ uint x; uint c; } mwc64x_state_t;
//blah...
If I get rid of the #include directive and copy/paste the content of "skip_mwc.cl" directly into this source, I can partially "build" and at least get some errors, showing that my compiler (clang9 cl compiler) can at least recognize the kernels code. With the #include approach I get the following error:
Build log::
<program source>:9:10: fatal error: 'skip_mwc.cl' file not found
#include "skip_mwc.cl"
I have checked and the file is there in the search paths, so I'm inclined to believe that my Xcode IDE doesn't index .cl files properly to perform automatic file inclusion (as in .c or .cpp).
I really want to avoid having to copy/paste source from one file into the other. Any suggestions from someone familiar with Xcode, who has encountered this problem and managed to solve it, are very welcome and needed.
Thanks,
A
Two possible solutions:
Set the -I include_dir compiler option in clBuildProgram(), see also this answer.
Read both files from C++ with fstream and string-concatenate their content.
Also see the option of embedding the OpenCL code into the executable via stringification macro.
I'm getting an RC2247 error (Symbol name too long) when attempting to display the dialogs in a Win32 app. The error is occurring in this file:
C:\Program Files (x86)\Windows Kits\10\Include\10.0.17134.0\um\winnt.h
This worked fine under VS2015. The error started when I upgraded to VS2017.
I have seen the following posts, they don't appear to be relevant because they pertain to prsht.h:
RC2247 : Cannot open Rc file : Resource explorer cannot load resource ; Load failed
http://social.msdn.microsoft.com/Forums/en-US/vcprerelease/thread/4a648d6a-ea81-44d3-89c2-57fa5caa6fd6
The error disappears if I comment out the entire resource.rc file. The error occurs if the RC contains the single line:
#include <winnt.h>
When I click on "Edit code"", nothing happens.
I am grateful for any suggestions.
We must not include windows.h or winnt.h to .rc file - this headers - for are for c/c++ compilers and not designed for RC (resource compiler which process .rc file). as result if we include such files we may get errors.
We need include #include <winres.h> to .rc files. this file specially designed for the RC compiler. Internally it included:
#include <winuser.rh>
#include <commctrl.rh>
#include <dde.rh>
#include <winnt.rh>
#include <dlgs.h>
#include <winver.h>
and define some macros.
All standard windows definitions, which we need/use in rc file - exist in winres.h (and it subincludes). From another side in it no extra symbols/definitions wich exist in windows.h - it's not needed for rc and some time can cause errors.
So simply #include <winres.h> at the beginning of resource files and all will be OK.
I have run into this complaint rc2247 when trying to edit the rc file in a project compiled in vs2010. This had been upgraded from vs2050. I found that if I chose to open the .sin file via 'version selector' instead of going straight to vs2010, then it still opens in vs2010 but there is no problem in editing the rc. I don't pretend to understand !

I am trying to use mciSendString in visual studio express 2013 (Visual C++) but I keep getting an error
Error 1 error C3861: 'mciSendStringA': identifier not found
I assume this i because I have not linked to the correct dll, but I cannot find any details online or on msdn about how to link to the dll. It seems quite strange that there wouldn't be more obvious documentation about this. Can someone tell me how to link to the dll?
EDIT:
Here is the code I am trying to run:
#include <Windows.h>
#include <iostream>
#include <mmsystem.h>
extern char command1[] = "open C:\\boing.mp3 type MPEGVideo alias 0";
extern char command2[] = "play 0 from 0";
int main()
{
mciSendStringA(command1, NULL, 0, 0);
mciSendStringA(command2, NULL, 0, 0);
}
To make mciSendString() to work, you need to link to winmm.lib.
Just adding winmm.lib to Project Properties > Linker > Input > Additional Dependencies will be fine.
Looking at mmsystem.h (admittedly from the V7.1A Windows SDK, which is the most recent I have installed), I can see that there's a #ifdef _WIN32 block in there. If _WIN32 is not defined, then mciSendStringA is not declared. Instead mciSendString is declared.
Check your project options and ensure that both WIN32 and _WIN32 are defined. I'm guessing that you started from a console project, rather than a Windows Application project, and that at least one of those isn't defined.
When I try to execute my qt program on another computer, I receive this error and crash:
Failed to load platform plugin "windows". Available platforms are:
windows
I know that this problem has been discussed in several other questions:
failed to load platform plugin "windows" Available platforms are: windows, minimal
Qt application: Failed to load platform plugin "windows". Available platforms are:
PyQt5 - Failed to load platform plugin "windows". Available platforms are: windows, minimal
But I have applied the suggested solutions, and it still doesn't work for me. Relevant information:
I use Qt 5.1.0 with MinGW 4.8 32bit for development
on my development pc (Win7, 64bit) the program executes just fine
I compiled my application in release mode
the target pc (Win7, 32bit) does not have Qt installed
part of my .pro:
QT += core gui opengl network xml testlib
TARGET = myApp
TEMPLATE = app
CONFIG += qtestlib help
CONFIG -= app_bundle
content of my deployment folder:

platforms/qwindows.dll
I had same issue with qwindows.dll -- win7 64 ok, win7 32 fail with unable to find qwindows.dll
first of all i checked i can run it with -platformpluginpath:
app.exe -platformpluginpath plugins/platforms
everything ok, so the problem is just wrong search pathes inside app.
I ended with just adding all possible pathes:
#include <QApplication>
#include <QDir>
void registerPluginsDir(QDir& exeDir)
{
#ifdef Q_OS_MAC
QString pluginsRelPath = "/../../PlugIns";
#elif defined(Q_OS_WIN)
QString pluginsRelPath = "Plugins";
#elif defined (Q_OS_LINUX)
QString pluginsRelPath = "../lib/plugins";
#else
#error "Unsupported OS"
#endif
QString platformsRelPath = "platforms";
QString pluginsPath = exeDir.absoluteFilePath(pluginsRelPath);
QString platformsPath = QDir(pluginsPath).absoluteFilePath(platformsRelPath);
QStringList pathes = QCoreApplication::libraryPaths();
pathes << pluginsPath;
pathes << platformsPath;
pathes << platformsRelPath;
pathes << pluginsRelPath;
QCoreApplication::setLibraryPaths(pathes);
}
int main(int argc, char *argv[])
{
QString exePath = QString::fromUtf8(argv[0]);
QFileInfo exeInfo (exePath);
QDir exeDir (exeInfo.absolutePath());
//need to set correct plugins path before app instance created
registerPluginsDir(exeDir);
QApplication app(argc, argv);
// more code here
return app.exec();
}
I am in a HUGE depression now! I spend 2 days trying to use boost.python . PLEASE guide me! I will explain what I did.
I have Winows 7 64 bit.
The Python is 64 bit 2.7.3 installed at C:\Python27_amd64.
Now, I take boost_1_54_0.zip and unzip in F: directory.
The I use cmd.
bootstrap
this creates project-config.jam. I edit it and insert
using msvc : 9.0 ;
using python : 2.7 : C:\Python27_amd64\python : C:\Python27_amd64\include : C:\Python27_amd64\libs ;
Now i do
.\b2
This process runs for 20 something minutes and I am told that boost has successfully been build.
After that I install boost binaries from http://sourceforge.net/projects/boost/files/boost-binaries/
The binaries get installed in C:\local\boost_1_54_0.
Now I want to create a General project.
Now, I use the code given for embedding python in C++ here
#include <boost/python.hpp>
#include <boost/detail/lightweight_test.hpp>
#include <iostream>
namespace py = boost::python;
using namespace std;
int main()
{
// Initialize the interpreter
Py_Initialize();
py::object main_module = py::import("__main__");
py::object main_namespace = main_module.attr("__dict__");
py::exec("print 'Hello, world'", main_namespace);
py::exec("print 'Hello, world'[3:5]", main_namespace);
py::exec("print '.'.join(['1','2','3'])", main_namespace);
}
I setup the header files and library in VC++ directories to F:\boost_1_54_0\boost_1_54_0 and F:\boost_1_54_0\boost_1_54_0\stage\lib respectively.
I also setup project-->properties-->configuration properties-->C/C++-->General-->Additional Include directories to C:\Python27_amd64\include
Likewise, I also setup project-->properties-->configuration properties--> Linker--> General to C:\Python27_amd64\libs;"C:\local\boost_1_54_0\lib64-msvc-9.0" .
Now when I compile using x64 debugger. It gives me an error
Unhandled exception at 0x00000000 in test8.exe: 0xC0000005: Access violation at location 0x0000000000000000.
I am struck since last 2 days...but thats the closest I have been since then. please help me!
So you mean a runtime error, right?
I think you should first ensure, that there is no exception thrown by boost::python itself.
First try to set the try block around you python calls with a catch(...)
If exception is caught it is most probably the boost::python::error_already_set exception.
So, you then should decode it like here
