I have the following line of code is giving me an error:
boost::asio::serial_port serial(ioservice, "COM3");
The errors are:
Exception thrown at 0x7602A8B2 in WindowsProject2.exe: Microsoft C++ exception: boost::wrapexceptboost::system::system_error at memory location 0x010FE4A8.
Unhandled exception at 0x7602A8B2 in WindowsProject2.exe: Microsoft C++ exception: boost::wrapexceptboost::system::system_error at memory location 0x010FE4A8.
I am trying to connnect to an arduino through COM3 port. I am using windows 32 desktop app. The code works for windows 32 console app. So it is a win32 desktop app error im guessing it doesn't like "COM3"? I also tried changing to unicode, multi byte set, and not set and still didnt work.
Just a guess, wrong serial of no permissions. It would be easy to find out by reading the error
try {
boost::asio::serial_port serial(ioservice, "COM3");
} catch (boost::system::system_error const& se) {
std::cout << "Error " << se.code().message() << "\n";
}

I am trying to call Matlab Functions from my OMNeT simulation. Therefore I created a shared library using the mwArray API. However, when I try to run the sample code, the simulation terminates with the following error message:
Error in final launch sequence:
Failed to execute MI command:
-exec-run
Error message from debugger back end:
During startup program exited with code 0xc0000135.
Failed to execute MI command:
-exec-run
Error message from debugger back end:

Did anyone else encounter the same problem?
I am using OMNeT 5.6.2 and Matlab 2020a under Windows
The code for my module is
#include <omnetpp.h>
#include "compilerTest.h"
using namespace omnetpp;
class ExampleModule : public cSimpleModule
{
protected:
simtime_t timerInterval;
cMessage * timer;
protected:
virtual void initialize();
virtual void handleMessage(cMessage *msg);
};
Define_Module(ExampleModule);
void ExampleModule::initialize()
{
timerInterval = 1.0;
timer = new cMessage("timer");
scheduleAt(simTime() + timerInterval, timer);
}
void ExampleModule::handleMessage(cMessage *msg)
{
if (msg->isSelfMessage()){
bool x = mclInitializeApplication(NULL, 0);
scheduleAt(simTime() + timerInterval, timer);
}
}
The message indicates that the error occurred during the startup of the process. It means that the process probably cannot load the Matlab runtime DLL. The directories where the Matlab DLLs reside must be present on the system path so the operating system can load them. On Windows it is especially hard to avoid DLL hell and fix these issues (mostly because of the lack of proper error messages). First, I would try to start the example from the MinGW env command prompt where you can control the PATH manually and try to run from the IDE only after it works in the command line.
I am trying to Initialize EGL with:
#include <GLES3\gl3.h>
#include <EGL\egl.h>
#include <EGL\eglext.h>
void main(){
EGLDisplay display = eglGetDisplay (EGL_DEFAULT_DISPLAY);
}
I got no error from compiling it but it crashed when i run it. When i try to debug it the eglGetDisplay throw the exception:
Unhandled exception at 0x7563CB49 in OpenGLES Examples.exe:
0xC0000005: Access violation executing location 0x00000000.
I have searched around but still no solution, please help.
I managed to solve it by using headers and libraries from ARM Mali SDK instead of AMD SDK. I still don't know how but it works for me.
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
I have tried both VS2010 and VS2008. In the process of trying to configure OpenCV with GPU, I have successfully compiled CUDA codes and OpenCV samples codes seperately.
But when I include the OpenCV libraries in my CUDA environment it doesn't work. The latest problem is when I compile my sample code I get the following exception:
First-chance exception at 0x7c812aeb in test.exe: Microsoft C++
exception: cv::Exception at memory location 0x0011fb18
My code is
/*this is the sample code in opencv website*/
#include "iostream.h"
#include "opencv2/opencv.hpp"
#include "opencv2/gpu/gpu.hpp"
int main (int argc, char* argv[])
{
try
{
cv::Mat src_host = cv::imread("file.png", CV_LOAD_IMAGE_GRAYSCALE);
cv::gpu::GpuMat dst, src;
src.upload(src_host);
cv::gpu::threshold(src, dst, 128.0, 255.0, CV_THRESH_BINARY);
cv::Mat result_host = dst;
cv::imshow("Result", result_host);
cv::waitKey(27);
}
catch(const cv::Exception& ex)
{
std::cout << "Error: " << ex.what() << std::endl;
}
return 0;
}
Any help will be appreciated.
DOn't look at the error box that pops up - look at the console window. OpenCV has error messages that are slightly more descriptive. Tell us what the console says.
I had a similar problem with this same code. I fixed it by
copying opencv_core243d.dll from E:\opencv\build\gpu\x64\vc10\lib folder to the work directory with the .exe.
Don't know why that should matter but it did.
Using cuda 5.0
VS2010 express
win 7 x64

I'm having problems trying to run a bunch of old 16-bit applications in Windows 2008 Server.
The applications ran fine up to Windows 2003 Server, but when I try to print from any of
them, all show printing errors (Unable to create printer driver / TERM error / etc)
The LPT1 port is redirected to a shared printer via NET USE LPT1 \ServerName\SharedPrinter
DIR > LPT1 (or any shell redirection to the printer) is working fine.
I'm using an Administrator account, so it shouldn't be a permissions problem, right?
To reproduce the behavior, I made a small test program in C (TCC 1.01 for DOS). It runs fine
in XP / 2003 Server, but on 2008 Server it shows the handle opening (5) but when is trying
to write in that handle, issues an error (Write fault error writing device LPT1, Abort, Retry,
Ignore, Fail)
#include <io.h>
#include <fcntl.h>
#include <sys\stat.h>
int main(void)
{
int handle, status;
char* sbuff;
handle = open("LPT1", O_WRONLY, S_IFBLK);
printf("%d\n", handle);
if (!handle)
{
printf("open failed\n");
exit(1);
}
sbuff = "[print test]\n";
write(handle, sbuff, strlen(sbuff));
close(handle);
getch();
return 0;
}
Any clues?
TIA,
Pablo
Mike A - I have discovered that syntax 'print /d:{lpt?} {filename}' is not working on Win2008, not from within a 16bit app OR from the command line. This syntax has been supported for years and we run it in 10 Win2003 servers. Might there be a configuration setting in Win2008 that would make it syntax compatible with previous versions of Windows? BTW, here is Microsoft Tech Bulletin that was updated April 2012 that list the syntax as being compatible with Win2008... http://technet.microsoft.com/en-us/library/cc731623.
