I set the options v8_use_external_startup_data=false
try to run the sample hello-world with out the file snapshot_blob.bin
it's ok when i use ninja to compile
but if i use g++ directly it failed
#
# Fatal error in , line 0
# Check failed: (i_isolate->snapshot_blob()) == nullptr.

I try to debug the program, find the code src/api.cc:8260
i_isolate->set_snapshot_blob(i::Snapshot::DefaultSnapshotBlob());
in the good program generated by ninja, the DefaultSnapshotBlob return a
section of data, length is 1329232
but in the bad program generated by g++, the DefaultSnapshotBlob return a
section of data, length is zero
DefaultSnapshotBlob was defined in src/snapshot/snapshot-empty.cc and just
return nullptr
there is another file: out.gn/release.x64/gen/snapshot.cc the function was
defined again,
i guess the defination in snapshot.cc is the real function to call , but
why it could return anything when i use g++ to compile binary?
can anyone help me?
