run resgui failed

[jwzl]

I run rescuegui and found the error!
lua_swupdate.so: undefined symbol: pthread_sigmask

can lua support call C shared library with depenecy?
I found the lua_swupdate.so has a dependcy for pthread?

how to fix this,
thank you very much!

This was an issue discussed some time ago on Lua mailing list. Lua does not link pthread and when a module is loaded using pthread, there is this issue. One way is to link the Lua interpreter with libpthread, but this was discouraged in the discussion because it is duty of the user and not of the language (that can run on other OS as Linux) to provide this.
You can easy start before by preloading the libpthread library, that is:

export LD_PRELOAD=/lib/libpthread.so.0
exec SWUpdateGUI.lua
