Successfully compiled and ran examples

[Christoph Hasse]

As requested for documentation just a short info what I did.

Running on a Dell XPS13 l502x with a GeForce GT525M and a Intel Core i7-2670QM.

I downloaded TCLAP and followed their installation instructions including "make install".

Then followed the provided instructions on the Github page.

My CMake output looks like this:

-- Could NOT find Doxygen (missing:  DOXYGEN_EXECUTABLE)

Since my little mobile graphics card doesn't have enough memory for the 10 million events the examples create I had to change that number to 1 million in the file "Generate.cu". 

After that the examples worked without a problem, besides a single small issue.

Cheers,

Hi Christoph,
Thanks a lot for this useful and precise feedback. Let me analyse it.

1- The cmake output seems truncated, since some information is missing...
I would expect it to report also GCC, CUDA and Thrust versions and path in your system. Probably it is the output of a second call to cmake.
 
2- It seems everything run ok in your machine. An interesting detail in that cmake reports your compile does not have official support for c++11.
So the code should not compile right? Instead it does... and the targets run without major problems.
Actually, this thing draw my attention to a small error in the CMakeLists.txt logic. I will correct it asap.

3-I confirm the issue with -e parameter to GenerateSample example.

So I will release a patch version during the week, addressing these issues and hopefully also improving the documentation.

Thank you very much to use MCBooster.

A.A.

as you can see the compiler test for c++11 works fine as I would expect for gcc 4.8.5. 

And you are right there is a small bug in line 53 of the CMakeLists.txt. I added a "NOT" and now the Output makes more sense as you can see above.

Cheers,
Christoph
