Hello,
I am getting a segfault when running deviceQuery on our target linux system. deviceQuery
was created with our cross-compiler and statically-linked with the libcudart_static library.
If I add –cudart shared to the NVCCFLAGS in the deviceQuery Makefile (aka no static link),
then running on our target platform works as expected. It does require the libcudart.so to
be present on the target.
Graphics card: RTX A4000 and RTX A2000
CUDA driver: 510.60.02
CUDA toolkit: 11.6.2
I am building deviceQuery with:
TARGET_ARCH=x86_64 SMS=“86” HOST_COMPILER=path to the toolchain/bin/g++ make
gdb backtrace:
(gdb) r

Any idea on how to resolve this? All of our other CUDA development follows this
same behavior with the statically-linked cudart.
Thanks for the help,
Dan
