Since you mentioned '-Wl,-export-dynamic', I assume you're compiling under Linux environment with GCC. Genrally, if you link with static V8, a '-rdynamic' in ldflags would do the job, if you still get symbol lookup errors, find if you have '-fvisibility=hidden' and '-fvisibility-inlines-hidden' in your cflags, which will hide all symbols. Another reason for this error is those symbols are garbage collected by compiler, see if you have ''-fdata-sections' and in cflags, and '-Wl,--gc-sections' in ldflags. -- Cheng Intel Open Source Technology Center -- v8-users mailing list [email protected] http://groups.google.com/group/v8-users
