pthread_create not found in ubuntu

Question

I am trying to run cocos2d-x on Ubuntu. It shows this error:

-- Looking for IceConnectionNumber in ICE
-- Looking for IceConnectionNumber in ICE - found
-- Found X11: /usr/lib/x86_64-linux-gnu/libX11.so
-- Found OpenGL: /usr/lib/x86_64-linux-gnu/libGL.so  
-- Looking for include file pthread.h
-- Looking for include file pthread.h - found
-- Looking for pthread_create
-- Looking for pthread_create - not found
-- Looking for pthread_create in pthreads
-- Looking for pthread_create in pthreads - not found
-- Looking for pthread_create in pthread
-- Looking for pthread_create in pthread - found
-- Found Threads: TRUE  
-- Could NOT find Doxygen (missing:  DOXYGEN_EXECUTABLE) 

What does this mean?

Answer 1

it seems like it eventually finds pthread_create but it is missing Doxygen. Run sudo apt-get install doxygen , and retry it.

Answer 2

pthread_create may be present in few different places. Script checked them all and found this function in pthread . Then it looked for Doxygen and was not able to find it. Install it and try again, script should be able to proceed.
