View Full Version : 1073741515 problem

This is the strangest thing I have seen in Qt. Built a simple test application with one external library plus qwt.
Just one other source file plus the main window.
Compiles fine, runs fine, no errors. Then just change the title in the main window. Recompile (ok) and run and get the 1073741515 error. I have tried this in multiple little test projects and it happens every time.
Driving me nuts, any advice greatly appreciated.
Thanks

When quote error numbers and messages it is important to be precise. The error number is "-1073741515" not "1073741515". The value -1073741515 is 0xC0000135 in hex, which basically means "some dll not found".
In this case it is likely to be the Qwt or the other library not being in the run-time environment.

Thanks Chris. Does it matter where the libraries are, so long as the pro file specifies the location correctly?
Here is the pro file:
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = Portaudio_Test
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp \
helloring.cpp
HEADERS += mainwindow.h \
helloring.h
FORMS += mainwindow.ui
INCLUDEPATH += C:/development/qt_projects/portaudio_test/portaudio/include
LIBS += -L"C:/development/QT_Projects/portaudio_test/portaudio/lib"
LIBS += -lportaudio_x86
INCLUDEPATH += C:/development/qt_projects/qwt/qwt-6.1-rc3/src
LIBS += -L"C:/development/qt_projects/qwt/qwt-6.1-rc3/lib"
LIBS += -lqwt
CONFIG += debug \
qwt

LIBS directive specifies location of lib files for linker. You have a problem with location of DLL files and this is a runtime problem.

The DLLs need to be in the same directory as the executable, the current working directory, one of the windows directories, or located somewhere on the PATH
