Cannot compile benchmarks

[TomasOberhuber]

When I try to build gunrock using make all I am getting the following

gunrock/benchmarks/bc_bench.cu(101): error: argument of type "const char **" is incompatible with parameter of type "char **"
      { []() {}(); nvbench::detail::main_initialize(1, args); { []() {}(); { []() {}(); std::vector<std::string> args = nvbench::detail::main_convert_args(1, args); []() {}(); nvbench::option_parser parser; []() {}(); parser.parse(args); []() {}(); nvbench::detail::main_print_preamble(parser); nvbench::detail::main_run_benchmarks(parser); nvbench::detail::main_print_epilogue(parser); nvbench::detail::main_print_results(parser); } []() {}(); } nvbench::detail::main_finalize(); []() {}(); } []() {}(); return 0;;

and many simillar errors. I use Arch linux, cuda_12.4.r12.4/compiler.34097967_0 and g++ (GCC) 13.2.1 20230801.

I've the same issue. As a workaround I used an older version of nvbench by entering an commit hash (9e8efa2c88b11a0253c0e7844fe45aee307e36e6) prior to the braking change into the GIT_TAG in cmake/FetchNVBench.cmake

Ah, thank you for the report. You should also be able to fix this by turning this option off:

gunrock/CMakeLists.txt

Lines 261 to 263 in a2e9f04

	option(ESSENTIALS_BUILD_BENCHMARKS
	"If on, builds Essentials with NVBench benchmarking support."
	ON)

Seems like the issue is with nvbench + gunrock.

As @neoblizz mentioned, this is related to a change in nvbench. I have a fix in the works.
