Hello,

This is Seo. I got some errors while building the multichain 2.0 source from 2.0-dev as follows:

on new installed Ubuntu 18.10, I followed readme.md and v8.md

1.

../../src/profiler/tracing-cpu-profiler.cc:26:3: error: use of undeclared identifier 'TRACE_EVENT_WARMUP_CATEGORY'
  TRACE_EVENT_WARMUP_CATEGORY(TRACE_DISABLED_BY_DEFAULT("v8.cpu_profiler"));
  ^
../../src/profiler/tracing-cpu-profiler.cc:27:3: error: use of undeclared identifier 'TRACE_EVENT_WARMUP_CATEGORY'
  TRACE_EVENT_WARMUP_CATEGORY(
  ^
2 errors generated.

2. (after commenting)

../../src/tracing/tracing-category-observer.cc:22:3: error: use of undeclared identifier 'TRACE_EVENT_WARMUP_CATEGORY'
  TRACE_EVENT_WARMUP_CATEGORY(TRACE_DISABLED_BY_DEFAULT("v8.runtime_stats"));
  ^
../../src/tracing/tracing-category-observer.cc:23:3: error: use of undeclared identifier 'TRACE_EVENT_WARMUP_CATEGORY'
  TRACE_EVENT_WARMUP_CATEGORY(

../../src/tracing/tracing-category-observer.cc:25:3: error: use of undeclared identifier 'TRACE_EVENT_WARMUP_CATEGORY'
  TRACE_EVENT_WARMUP_CATEGORY(TRACE_DISABLED_BY_DEFAULT("v8.gc_stats"));
  ^
../../src/tracing/tracing-category-observer.cc:26:3: error: use of undeclared identifier 'TRACE_EVENT_WARMUP_CATEGORY'
  TRACE_EVENT_WARMUP_CATEGORY(TRACE_DISABLED_BY_DEFAULT("v8.ic_stats"));
  ^
4 errors generated.

3. (after commenting, and then It went forward well, at last, when I typed "mc20@ubuntu:~/multichain/v8build$ python $MULTICHAIN_HOME/depends/v8_data_lib.py")

    raise child_exception

I couldn't finish that work. So I need your help.

Thank you!

The V8 toolset changes quite regularly, so it's likely there's an issue compiling that appeared since we released 2.0 beta 1. We're working on improving the compilation process to solve this problem – for now it's recommended to use the binary distribution.
