V8 profiling: linux-tick-processor not working with d8
javascript, javascript-engine, node.js, v8
Solution
There is a bug in V8. I opened a bug report here: http://code.google.com/p/v8/issues/detail?id=2364
Problem
I'm trying to get the v8 profiling and linux-tick-processor working on my ubuntu. Basically I have done these steps: ``` $ git clone git://github.com/v8/v8.git v8 && cd v8 $ make dependencie $ make native // added d8 to $PATH $ d8 --prof primes.js // v8.log is created $ /home/username/v8/tools/linux-tick-processor ``` But it is not working, as a result i get: ``` Statistical profiling result from v8.log, (0 ticks, 0 unaccounted, 0 excludes). ``` So i assume the v8.log is not created correctly, because this result is stated with every other file you give the linux-tick-processor. I checked the v8.log and it is created with some content: http://pastebin.com/VLLWMKKM For me it seems like it was generated correctly. I tried profiling with node and this works: ``` $ node --prof primes.js $ /home/username/v8/tools/linux-tick-processor // correct output ``` But I want to use the d8 profiling. Does someone has any idea or solution for this problem? Thanks in advance.
