I'm using V8 32-bit Version 4.10.253 compiled with Visual Studio 2015.
I'm trying to run the example that Google has at:
Chrome V8 - Getting Started
But when I try to run it, I get:
Exception thrown at 0x00000000 in V8Test.exe: 0xC0000005: Access
violation executing location 0x00000000.
I get this when the following is executed:
Isolate* isolate = Isolate::New(create_params);
My project settings:
To get the project to compile in debug, I set the runtime library to:
Multi-threaded Debug /MTd.
I include the v8 include directory under additional include directories.
Lastly, I include the following libraries:
icuuc.lib icui18n.lib v8_libplatform.lib v8_external_snapshot.lib
v8_base_3.lib v8_base_2.lib v8_base_1.lib v8_base_0.lib v8_libbase.lib
winmm.lib
Anyone know what I'm doing wrong? Thanks in advance.
Ok, I feel stupid. I didn't finish reading the rest of the tutorial. You must copy all the .bin files where your executable is stored. Specifically:
natives_blob.bin
snapshot_blob.bin
V8 will crash at Isolate::New if you do not.

I have a very simple c++ sample project that basically just logs in to a 3rd party library (collection of .lib files)
There are 4 provided configurations md,mdd,mt,mtd. All x64.
I can build in mdd mode and run the Exe file directly, and the program works fine.
But if I run the debugger in VS, the 3rd party library throws a runtime Exception "vector deleting destructor".
try
{
engine = new Engine(¶ms);
}
catch (XxxException& Ex)
{
return (ERROR);
}
Exception thrown at 0x00007FFA52003FB8 in Sample.exe: Microsoft C++ exception: XxxException at memory location 0x000000224C53F190.
Exception thrown at 0x00007FFA52003FB8 in Sample.exe: Microsoft C++ exception: XxxException at memory location 0x000000224C53F690.
0x00007ff75d5ab3e0 {Sample.exe!const XxxException::`vftable'} {0x00007ff75d2d8a50 {Sample.exe!XxxException::`vector deleting destructor'(unsigned int)}}
So I am unable to debug.
What is this error, and why does it only occur in VS Debugger?
The solution was to change the working directory as specified in Debugging from $(ProjectDir)
to $(TargetPath), where the exe was sitting!
isn't C++ a wonderful artifact of history!
I'm trying to build a game in sfml under windows 10.It shows successful at the time of building.whenever i debug the solution it shows the error message like:
Unhandled exception at 0x00007FFA622C21F9 (sfml-system-2.dll) in picpuz2.exe: 0xC0000005: Access violation reading location 0x0000000000000019.
Under call stack the program stopped at the code:
window.create(sf::VideoMode(300, 300, 32), "PICPUZ");
This is my code:
Please follow the tutorials closely. If you are doing a debug build, you should link with the dlls that end in -d for debug.
For example sfml-system-d-2.dll
Linking release and/or debug to the wrong configuration (release to debug or debug to release) will result in unpredictable crashes.
I stumbled upon an interesting problem. I have managed to reduce the problem to the following code:
boost::property_tree::ptree properties;
boost::property_tree::read_xml("Additional Dependencies\\properties.xml", properties);
xml:
<Properties>
<PictureGenerator>
<miniatureHeight>4</miniatureHeight>
<miniatureWidth>4</miniatureWidth>
<imageHeight>8</imageHeight>
<imageWidth>8</imageWidth>
<ImagePath>Additional Dependencies\</ImagePath>
<Miniatures>
<Image>0.bmp</Image>
<Image>1.bmp</Image>
<!--<Image>2.bmp</Image>
<Image>3.bmp</Image>
<Image>4.bmp</Image>-->
</Miniatures>
</PictureGenerator>
</Properties>
When i build the project in Release mode, everything runs perfectly.
In Debug mode I get the following error:
Unhandled exception at 0x779e8e19 in my_project.exe: 0xC0000005: Access violation writing location 0x00000014.
I am using VS2010.
Upon further inspection the error is thrown in the read_xml_internal function while trying to create a vector from a basic_istream.
At first I thought that I gave the wrong path, but I works perfectly in Release mode.
I have found the source of the problem.
I have reproduced the same error with istream, and it turned out that I had a wrong property page set for Debug.
The problem was the property:
C/C++ -> Code Generation -> Runtime Libary as Multi-threaded
I have changed it to Multi-threaded Debug Dll and it works perfectly.
Using Visual Studio 2010, OpenCV 2.2.2, Windows 7 64x
My code builds successfully then when it goes into debug I get the following error:
First-chance exception at 0x75f0c41f in MachineVisionHW0.exe: Microsoft C++ exception: cv::Exception at memory location 0x002dec90..
Unhandled exception at 0x75f0c41f in MachineVisionHW0.exe: Microsoft C++ exception: cv::Exception at memory location 0x002dec90..
Then I end debug, go to the file directory and run the built executable and it runs fine. Does anybody know how to fix this? It isn't keeping me from building my code, but it is incredibly inconvenient. I will include an example of the code that is doing this below.
int main(){
cv::Mat image1 = cv::imread("img1.JPG", CV_LOAD_IMAGE_GRAYSCALE);
cv::namedWindow("Sample1");
cv::imshow("Sample1", image1);
cv::waitKey(0);
return 1;
}
Do you get the unhandled exception before main?
If not, then your code is somehow doing something to raise the exception. Put a breakpoint on the first line, then hit F5, then once at the breakpoint, step through the code one line at a time to see which one causes the exception, F10 key to do this.
My gut feeling is that when running from the debugger, the cv::imread is failing since it is not finding the img1.jpg from the expected location, the current working directory is that of the solution file, not of the debug output build dir. You can do a quick test and copy the img1.jpg to the dir containing the sln file and see if that fixes the problem.
Following on the tails of my previous (answered) question...
SharpSvn makes calling the Subversion client API simple:
SvnClient client = new SvnClient();
client.Authentication.DefaultCredentials = new NetworkCredential(username, password);
client.CheckOut(new Uri("http://xxx.yyy.zzz.aaa/svn/repository"), workingCopyDir);
On the other hand, calling the client API from C/C++, as shown in minimal_client.c requires coding "closer to the metal", as it were, on Subversion.
Are there Windows libraries for C++ in Visual Studio 2003 that present a simpler interface than what minimal_client uses?
If there are not, is there a VS2003 C++ project (a .vcproj file) that demonstrates getting minimal_client to run? I'm able to compile minimal_client.c and link it using the following libraries:
libsvn_client-1.lib libsvn_delta-1.lib libsvn_diff-1.lib libsvn_fs-1.lib libsvn_fs_base-1.lib libsvn_fs_fs-1.lib libsvn_ra-1.lib libsvn_ra_local-1.lib libsvn_ra_svn-1.lib libsvn_repos-1.lib libsvn_subr-1.lib libsvn_wc-1.lib libapr-1.lib libaprutil-1.lib xml.lib libneon.lib
but when I run my application (in the debugger or start the release build without debugging), it runs for about 20 seconds without hitting the first line of main() and then throws this exception:
An unhandled exception of type
'System.TypeLoadException' occurred in
Unknown Module.
Additional information: Could not load
type apr_pool_t from assembly
minimal_client,
Version=1.0.3477.16033,
Culture=neutral, PublicKeyToken=null.
I've tried various combination of libsvn_.lib and svn_.lib to no avail.
Any thoughts on what I'm doing wrong?
EDIT: I started fresh with a "Win32 Console Project" (still in VS2003) and I am now able to debug the first few lines of my app. But now, on this line:
if (svn_cmdline_init ("minimal_client", stderr) != EXIT_SUCCESS)
I get a different exception (in the debugger or start the release build without debugging):
Unhandled exception at 0x7c91b21a in
Win32ConsoleProject_minimal_client.exe:
0xC0000005: Access violation writing
location 0x00000010.
EDIT: This thread explains that this error is a CRT mismatch between svn and stderr in my app. If I don't want to build Svn so they match (I don't want to), I can pass NULL instead of stderr (provided I'm willing to do without messages that would go to stderr) When I did this, my app ran all the way through correctly.
It seems that C++ wrappers are not overflowing the 'net. However, you may want to try SVNCPP, which can be yoinked from RapidSVN.
See http://rapidsvn.tigris.org/ for details (note: I've not tried it).
Can you upgrade to Visual C++ 2005 ? If so, you could just go using SharpSvn with C++/CLI.
Or even maybe stick to VC2003 and go SharpSvn with Managed C++ ? (not that I have any knowledge on the how od even the if)
edit: oh well, SharpSvn's homepage explicitely states that VC++ 2005 SP1 is required...
