Here's an example command line I use to compile/link a program (on OS X); clang++ -I./ -I/Users/xaxxon/v8 -std=c++14 -I/usr/local/include -Wall -Werror samples/exception_sample.cpp -o samples/exception_sample -L/usr/local/lib -L/Users/xaxxon/v8/out/x64.debug/ libv8toolkit.a -lv8_base -lv8_libbase -lv8_base -lv8_libplatform -lv8_nosnapshot -licudata -licuuc -licui18n
You can see I link against libv8_nosnapshot On Sat, Feb 27, 2016 at 11:52 PM, Danny Dorfman <[email protected]> wrote: > Zac, I don't quite follow you.
