Building SHOC #67

Open MahmoudAbdelrehim opened 4 years ago

MahmoudAbdelrehim commented 4 years ago

I have got an error while trying to build the shoc directory the problem is while compiling for BusSpeedDownload, hence my cuda path is set. one of the errors I have got is: /common/main.cpp:60: undefined reference to `cudaSetDevice' ... Makefile:329: recipe for target 'BusSpeedDownload' failed make[4]: *** [BusSpeedDownload] Error 1

specifying the cuda libs during configure solved it for me: ../configure LIBS="-lcuda -lcudart"

Not sure what caused it though. For me it worked well with cuda 10.0 on a NVIDIA Jetson TX2 and after I wiped it and flashed it with a newer cuda version 10.2 I got the linker errors.

It seems like for some reason config/find_cuda_libs.sh is not able to extract the libraries anymore.

Edit: you also need to set LDFLAGS: ../configure LIBS="-lcuda -lcudart" LDFLAGS="-L/usr/local/cuda/lib64"

add ' -lcuda -lcudart' to common.mk.in 

……
LIBS      = @LIBS@ -lcudart -lcuda
……

btw, compile SHOC in nvidia , and occurred error message " nvcc fatal : unsupported gpu architechture 'compute_30'" you can disable gencode=arch=xxx with `CUDA_CPPFLAGS='-I/usr/local/cucda/include" to fix it.
