ld: symbol(s) not found

Accelerated Computing CUDA CUDA Programming and Performance

This might be a very basic issue, but I get the “ld: symbol(s) not found” error when using make to compile the samples. Specifically:

q - obj/release/bank_checker.cpp_o

q - obj/release/cmd_arg_reader.cpp_o

q - obj/release/cutil.cpp_o

q - obj/release/stopwatch.cpp_o

q - obj/release/stopwatch_linux.cpp_o

q - obj/release/multithreading.cpp_o

q - obj/release/paramgl.cpp_o

q - obj/release/param.cpp_o

q - obj/release/rendercheck_gl.cpp_o

make -C projects/alignedTypes/

What is the problem here?

I’m seeing the exact same problem; not sure what the cause is yet, as I’ve built the examples successfully on an ostensibly identical MacBook Pro . . . there must be some difference in environment/compiler/etc., however. I’ll let you know if I find anything useful.

I ended up reinstalling the OS for other reasons and the examples compile fine now. So I must have messed up something with the compiler/environment/etc.
