[lldb-dev] finding the symbol dependencies of a bundle, like dyldinfo -lazy_bind -export

[Greg Clayton]

A quick clarification on the args to CreateTarget:

"filename" is just a full path to the local object file you want to observer. "target_triple" is your <arch>-<vendor>-<os>, or something like "x86_64-apple-darwin" or "i386-pc-linux" and can be NULL if the file is only a single architecture. "platform_name" can be NULL. "add_dependent_modules" should be false, since you are only interested in seeing the one object file itself, an SBError instance  should be created and passed in.
