-fno-omit-frame-pointer equivalent compiler option for clang

问题 I want to use DS-5 Streamline profiler to profile my code. In the documentation its mentioned that to be able to see call stacks, we need to compile code with compiler option -fno-omit-frame-pointer . This option is there in gcc. Is there an equivalent option for clang also? -fno-omit-frame-pointer is not working for me with clang. I have also tried setting the compiler optimization level to 0, but still I am not getting call stacks in streamline. 回答1: It looks like DS-5 is an ARM thing, so

Gnuplot , pm3d with contour lines

问题 i am 3d plotting a matrix with some values, and i need to add contour lines to the plot, is there a simple gnuplot command to do this? I tried the command: "set contour base" but only 1 line came up, i think it should be many lines. See matlab picture When i plot it in gnuplot i only get 1 contour line in the top left corner.But everything else is correct. My goal is to get it to look like in matlab like this Matlabplot I also found this example: see link in comments (dont have enough rep),
