I successfully compiled PMacc with C++11 on my local machine and hypnos (HZDR cluster) with CUDA 7 and 7.5 with gcc 4.8.2 as the host compiler.

So your problem is simply: CUDA 6.5 does not support C++11. The first error should have already beaten you to it error: identifier "nullptr" is undefined. nullptr is a C++11 feature. So if the compiler complains about it, it is not a C++11 compiler ;)

For future use: set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -std=c++11") in the CMakelists enables C++11 support for CUDA and host compiler. Probably running $PICSRC/configure -c"-DCUDA_NVCC_FLAGS='-std=c++11'" <pathToCase> would already solve the problem. Do not try to pass it to XCompiler as nvcc must know about that!

Probably related to this post on so

I think the gnu compiler 4.8 not supports c++11 very well also nvcc with the toolkit 6.5 not supports c++11.
Please try to use gnu 4.9.2+

psychocoderHPC picture psychocoderHPC on 28 Sep 2015

@anshumang funny, the stackoverflow answer you linked is my answer ;)

to make it short: PIConGPU does not yet have official C++11 support (not even for host-side compilers), nor are our build scripts yet designed for it.

We are currently adding more support to PMacc to work with C++11 in dev, but this is just part of the story. We are planning to move to a fully-flavoured C++11 code base in roughly two stable releases in both device and host-side kernels, but since this needs a lot of work, will cause some re-designs of input files and we will need CUDA 7.0+ (or maybe even 7.5) on all machines for it we can not rush it (nor do we have the capacities to quickly spin of a preview).

Due to the very "conservative" CUDA version updates on Titan (vendors need to adapt to new drivers/apis/frameworks and environments need to stay stable), it is likely to be the major machine holding back our C++11 upgrade. I personally expect official host&device C++11 support in early/mid 2016 on it earliest.

In case the newer version of gcc as suggested by @psychocoderHPC does not help about it:
Do you urgently need C++11 or can you compile and link the parts using C++11 separately?

Also: how did you pass the flag exactly (env var, cmd line, etc.)?

ax3l picture ax3l on 28 Sep 2015

tried it with module gcc/4.9.3 (not supported by CUDA 6.5) and the default gcc/4.8.2 with export CXXFLAGS="-std=c++11" and got the same problem.

also $PICSRC/configure -c"-DCUDA_NVCC_FLAGS='-Xcompiler=-std=c++11'" <pathToCase> did not cut it, but as I said our scripts are also not yet tuned to support it.

seems like export CXXFLAGS="-std=c++11" and $PICSRC/configure -c"-DCUDA_PROPAGATE_HOST_FLAGS=OFF" <pathToCase> could work, maybe passing some more -Xcompiler= flags for now...

Thanks @psychocoderHPC and @ax3l for following up...I wanted to use C++11 for the convenience of thread, condition_variable, mutex and unique_lock....I fell back to using pthread_*...

anshumang picture anshumang on 28 Sep 2015

I feel your pain :S

you could also go with boost thread or boost asio for the while.

ax3l picture ax3l on 28 Sep 2015

Finally using nanomsg which is trouble-free on Titan :relieved:

the problem is, that is not the case: CUDA 6.5 added undocumented, experimental C++11 support (_in_ kernels). pretty weird.

ax3l picture ax3l on 29 Sep 2015

Interesting... Then I assume he did not pass the flag to nvcc or nvcc did not pass it to the host compiler. CUDA 7 kinda works with C++11 and picongpu although I'm currently preparing 2 commits to fix some picongpu/pmacc related issues

Flamefire picture Flamefire on 29 Sep 2015

could also be cmake version related, I think to remember there were also changes in the CUDA module related to the new flags.

ax3l picture ax3l on 29 Sep 2015

Should not be the case. CUDA_NVCC_FLAGS are passed to nvcc in any CMake version IMO. If that still results in an error I'd need to see the make VERBOSE=1 output of the compiler invocation.

with cmake 2.8.10.2.

Hm, I might be right with cmake support history, see e.g. this commit.

ax3l picture ax3l on 29 Sep 2015

@ax3l You need to pass the flag to nvcc. So either CUDA_PROPAGATE_HOST_FLAGS must be set to ON or you can also directly set it in the CUDA_NVCC_FLAGS. As mentioned above the following works for picongpu:
$PICSRC/configure -c"-DCUDA_NVCC_FLAGS='-std=c++11'" <pathToCase>
Or for cmake it should be:
cmake -DCUDA_NVCC_FLAGS='-std=c++11' <...>

thx for the help @Flamefire !

he will close

  • #1035 (with PR #1151)
  • and will define a constexpr macro for C++11 compile on parts where we use static float x = value; inside classes (can't find an issue number right now)
ax3l picture ax3l on 29 Sep 2015

@ax3l I added issue #1154

Flamefire picture Flamefire on 30 Sep 2015

@Flamefire thx!

ax3l picture ax3l on 30 Sep 2015

Almost done. -> #1155
However I run into another known boost bug: https://svn.boost.org/trac/boost/ticket/6779
Compilation with C++11 should work with boost >= 1.57 and after #1155 and #1156 are merged.

Flamefire picture Flamefire on 30 Sep 2015

@Flamefire awesome :sparkles: :rocket:

ax3l picture ax3l on 1 Oct 2015

I also got the same errors. I added -DCUDA_PROPAGATE_HOST_FLAGS=OFF in cmake for compiling opencv, no errors again.

tmmt2007 picture tmmt2007 on 5 Sep 2017

Interesting solution, thanks for reporting!

Admittedly, we are not the OpenCV project but this CMake flag is still good to know!
