I want to call QNetworkReply::readAll as shown in Foo() such that once it completes, another time it should be called.
QString Foo (QString& requestUrl)
{
QNetworkReply *pReply = NetManager::getManager()->get(requestUrl,NULL,NULL);
QEventLoop loop;
QObject::connect(pReply,SIGNAL(finished()),&loop,SLOT(quit()));
loop.exec();
return pReply->readAll();
}
I want this because my Qt Gui application crashed with 0xC00000FD: Stack overflow exception. and in callstack, I got repeated calling of functions as shown in below callstack.
I don't understand that despite of using QEventLoop to make call to readAll() synchronous, how recursion is possible.
My Gui application is used by user to click and initiate readAll().
Is there a way to prevent the crash?

You are getting various errors and warnings here, but they aren't really about Docker or OpenSSL. If we strip away the extraneous information, here are the problems you are encountering.

The core of the problem here is probably that you are using a legacy version of Nginx in this project. From the GitHub repository you pointed to, in install-nginx.sh:
NGINX_VERSION=1.8.0
The current mainline version of Nginx is 1.13.2. I haven't combed through the changelogs for Nginx, but based on the errors you are receiving, it seems likely that between the 1.8 releases and the current ones, OpenSSL has deprecated various functions that Nginx 1.8 relied on. Most likely this can be solved by moving to a recent release of Nginx.
As of this writing, 1.13.2 is the current mainline, and 1.12.0 is the current stable. One of those may work better. Whether you can simply drop this in, I can't say. You may have to change something in the build scripts or the nginx config for a more recent version to work properly.
you are getting this error because your nginx version don't support SSL 1.1.0. Either upgrade NGINX version or use SSL 1.0.2.
I've got a custom source that seams to work with a simple topology. When QueryInterface gets called the stack looks like this:
MySource.dll!MySource::QueryInterface(const _GUID & riid, void * * ppv) Line 83 C++
mfcore.dll!CMediaEventPtr::GetUnknown(struct IMFMediaEvent *,struct _GUID const &,void * *) Unknown
mfcore.dll!CMPSourceManager::OnNewStream() Unknown
mfcore.dll!CMPSourceManager::OnSourceEvent() Unknown
mfcore.dll!CMPSourceManager::OnSourceEventAsyncCallback::Invoke(struct IMFAsyncResult *) Unknown
Using the same custom source without a topology, letting IMFCaptureEngine deal with that. When QueryInterface gets called the stack looks like this:
MySource.dll!MySource::QueryInterface(const _GUID & riid, void * * ppv) Line 42 C++
mfcore.dll!CMediaEventPtr::GetUnknown(struct IMFMediaEvent *,struct _GUID const &,void * *) Unknown
mfcore.dll!CSeqSourceWrap::HandleUpdatedStream(struct IMFMediaEvent *) Unknown
mfcore.dll!CSeqSourceWrap::OnSourceEvent() Unknown
mfcore.dll!CSeqSourceWrap::OnSourceEventAsyncCallback::Invoke(struct IMFAsyncResult *) Unknown
In the topo case, I then get a call to GetStreamDescriptor and RequestSample and everything works.
MySourceCPP_COM.dll!MyStream::GetStreamDescriptor(IMFStreamDescriptor * * ppStreamDescriptor) Line 187 C++
mfcore.dll!CMPSourceManager::OnNewStream() Unknown
mfcore.dll!CMPSourceManager::OnSourceEvent() Unknown

mfcore.dll!CBitPump::OnSinkEvent() Unknown
mfcore.dll!CBitPump::OnSinkEventAsyncCallback::Invoke(struct IMFAsyncResult *) Unknown
In the IMFCaptureEngine case I never get either call so data never flows.
I see the only difference is CMPSourceManager vs. CSeqSourceWrap.
Sometimes, a modal popup dialog (QDialog subclass) will disappear or hide 'on its own'; it will continue to block all events to the main page but will be invisible, thus forcing a program restart. This will happen on some runs of the program but not others, with what appear to be identical inputs. Using the debugger, I can see that the program is indeed stopped on the exec() function call. However since the dialog is invisible there is no way to interact with it. The dialog is created with
QDialog( parent, Qt::Dialog | Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint )
and
setModal(true);
How can I figure out what's going on here?
Edit 1: A little more code although I don't think it adds much:
ModalDialog dialog( this, "Display text" );
dialog.Run(); //Just calls exec()
It's really as simple as this. However, the call stack might be more revealing; Hooli.exe!ModalDialog::Run(bool async) occurs twice--how could that happen?

Im programming an Arduino mega 2560.
And I bought an tft LCD and for that I want to use a SD card so I can put my pictures on it.
I downloaded this library but its giving me errors.
C:\Arduino\libraries\pff\pff.cpp: In function 'FRESULT pf_read(void*, short unsigned int, short unsigned int*)':
C:\Arduino\libraries\pff\pff.cpp:585: error: invalid conversion from 'void*' to 'unsigned char*'
The problem is imo here:
pff.cpp:
FRESULT pf_read (
void* buff, /* Pointer to the read buffer (NULL:Forward data to the stream)*/
WORD btr, /* Number of bytes to read */
WORD* br /* Pointer to number of bytes read */
)
pff.h:
FRESULT pf_read (void*, WORD, WORD*); /* Read data from the open file */
When I make it a .c file, it gives me more errors, like this one:
tft_menu.cpp.o: In function `open_root_dir()':
C:\AppData\Local\Temp\build7310099894910129341.tmp/tft_menu.cpp:594: undefined reference to `pf_opendir(_DIR_*, char const*)'
tft_menu.cpp.o: In function `mount_sd()':
C:\AppData\Local\Temp\build7310099894910129341.tmp/tft_menu.cpp:583: undefined reference to `disk_initialize()'
C:\AppData\Local\Temp\build7310099894910129341.tmp/tft_menu.cpp:585: undefined reference to `pf_mount(_FATFS_*)'
tft_menu.cpp.o: In function `bitmap_show(char*)':
C:\AppData\Local\Temp\build7310099894910129341.tmp/tft_menu.cpp:472: undefined reference to `pf_open(char const*)'
C:\AppData\Local\Temp\build7310099894910129341.tmp/tft_menu.cpp:476: undefined reference to `pf_read(void*, unsigned short, unsigned short*)'
C:\AppData\Local\Temp\build7310099894910129341.tmp/tft_menu.cpp:518: undefined reference to `pf_read(void*, unsigned short, unsigned short*)'
tft_menu.cpp.o: In function `show_bitmap()':
C:\AppData\Local\Temp\build7310099894910129341.tmp/tft_menu.cpp:603: undefined reference to `pf_readdir(_DIR_*, _FILINFO_*)'
so I think it should be compiled as a cpp.
EDIT:
I found out that I have to save is as cpp and in the program I have to write what icktoofay states
After that I got some errors, so I went to the line 585, as stated above and changed
BYTE *rbuff = buff;
into
BYTE rbuff = (unsigned char) buff;
And I found out that I had to add mcc.h to get rid of the errors of the "couldnt find resources".
And now Im getting these errors:
C:\libraries\mmc/mmc.h: In function 'void init_spi()':
C:\libraries\mmc/mmc.h:21: error: 'PORTL' was not declared in this scope
C:\libraries\mmc/mmc.h:21: error: 'PORTL0' was not declared in this scope

C:\libraries\mmc/mmc.h:28: error: 'SPSR' was not declared in this scope

Ive tried to add #include TFT_ARDUINO_MEGA.h on top of the mcc.h and still no luck
Compile it as a C file, but in the file that uses it, include pff.h like this:
extern "C" {
#include <pff.h>
}
