I am having the same problem with the aorta3d example via the gpu_only.mk configuration option during the compilation of the example.
“Call of overloaded f(x) is ambiguous” error is generated (no executable) where f(x) is log(const double&), log1p(double), sin(double&) and various other math functions.
I am using a RTX4070 Mobile GPU and running CUDA v12.2. Also the CUDA_ARCH variable is set to 87 in config.mk and rules.mk files.
Additional question: Since my gpu architecture is Lovelace yet the last entry on rules.mk table is Ampere with architecture number 87, should I keep using 87 or may I use 89 as that is what my card supports?
