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:
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.
There is a bug in V8. I opened a bug report here: http://code.google.com/p/v8/issues/detail?id=2364
