Generating problem

[Airplane5]

While compiling MegBA. Some problem occured.

:~/MegBA/build$ make
[  7%] Built target cuManager

I am using cuda 11.6 with nvidia-driver-510.

BTW, I have installed
libnccl2=2.12.10-1+cuda11.6 libnccl-dev=2.12.10-1+cuda11.6

After un- and re-installation cuda and nccl, generating error above disappeared, but another error apeeared with repeated warnings.
There are mainly two warnings:

MegBA/thirdparty/Eigen/src/Core/util/DisableStupidWarnings.h(82): warning #20236-D: pragma "diag_suppress" is deprecated, use "nv_diag_suppress" instead

and

MegBA/thirdparty/Eigen/src/Core/util/Memory.h(291): warning #20014-D: calling a __host__ function from a __host__ __device__ function is not allowed

New error was:

/usr/bin/ld: BAL_Float: hidden symbol `__cudaUnregisterFatBinary' in /usr/local/cuda-11.6/lib64/libcudart_static.a(cudart_static.o) is referenced by DSO
/usr/bin/ld: 最后的链结失败: 错误的值

I have tried add "set(CMAKE_CXX_FLAGS_RELEASE "{CMAKE_CXXFLAGS_RELEASE} -fPIC")" into CMakelists.txt as some blogs said, but nothing changed.

Hi,

I guess this is because we only generate device code for SM60 (a.k.a Pascal arch). I have fixed this in #27, but I am not sure this will work for you. Try the latest version. If you have any problems, feel free to discuss them.

Best regards,
Jie
