Hi Lua community...


Hi!



I want to build LuaLanes 2.0.10 on Linux (with Lua 5.1.5). No problem to compile it, but upon requiring 'lanes' one gets:

./lua: error loading module 'lanes' from file './lanes.so':
     ./lanes.so: undefined symbol: pthread_mutexattr_settype

How can I resolve this?


I found this in the Makefile of Lanes 3.6.0:

    ifeq "$(shell uname -s)" "Linux"
      # -D_GNU_SOURCE needed for 'pthread_mutexattr_settype'
      CFLAGS += -D_GNU_SOURCE -fPIC



-Wolfgang
