[Espeak-general] can't make espeak

[Eric A. <eri...@gm...>]

I am a Chinese Coder, I want to study espeak,
I try to compile it in my Mac as followings

1, I downloaded speak-1.37-source
2, cd speak-1.37-source/src
3, make
    found error
ld: library not found for -lportaudio
4, I comment #AUDIO = portaudio
    found error
In file included from event.cpp:39:
debug.h:19:21: warning: anonymous variadic macros were introduced in C99
event.cpp: In function 'int sleep_until_timeout_or_stop_request(uint32_t)':
event.cpp:403: error: 'sem_timedwait' was not declared in this scope
make: *** [x_event.o] Error 1

Would you tell me, how to compile it?
