[Qt-interest] QTCreator + CUDA seems to crash my program

[Cole, Derek]

I will give it a look, but I know I did a clean in QTCreator. I then rebuilt my library and added a junk line like "int temp = 0;" and it moved the line number to the one below it, which was the original source it pointed to.

I will try again and manually delete all the object files and such just to make sure

Hi Derek, 
 
Sounds like you haven't rebuilt everything after changing the define?  Or a
similar compiler/linker mixup.  (The line numbers compiled into the .obj
files no longer match the source code).  
 
Hope that helps, 
 
Tony

Actually, this is weird. I re-compiled my library in debug mode so I could
get al ittle bit of info.

I do compile it with a flag -DUSING_CUDA just so I can keep the code
separated. This is what I have done in this version that is crashing.
However, I have two different methods with different names that essentially
do the same thing.

one is defined:

#ifdef USING_CUDA
bool cSicdReader::getDataCu(cuComplex *buffer, offset rowNum)
{.....
#endif

and the next is
bool cSicdReader::getData(complex<float> *buffer, offset rowNum)
{...

so the weird part is, in debug mode, it shows my code crashing on this line
of my QT project:
                    reader->getData(pixelData, imageRow);

but in my library, it is stopped on a line within the getDataCu function!

Hello all,

I have a library that I have been using for a while within my QTCreator
project. Recently, I developed some CUDA methods that one of those library
functions can call if the library was compiled with -DUSING_CUDA. The whole
library is archived into a .a file

I am trying to continue using that library, however, now my QTCreator
project crashes. I was able to get it to compile by adding the cuda shared
libraries to the LIBs in the makefile generated by QTCreator, so that was
the first hurdle.

Now, however, whenever I call some functions in that library (unrelated to
the CUDA stuff), my program crashes and says it has unexpectedly finished.

Is there something I dont know about using libraries that have CUDA
components linked into them from QT? When I build out a driver to test the
functionality of my library with the CUDA functions, it runs fine, and
doesnt crash.

Thanks

Derek
