From: http://jeetworks.org/node/151: This error:
m_syscall.c:525:1: error: unknown type name '__private_extern__' m_syscall.c:526:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'do_syscall_unix_WRK' m_syscall.c:549:1: error: unknown type name '__private_extern__' m_syscall.c:550:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'do_syscall_mach_WRK' m_syscall.c: In function 'vgPlain_do_syscall': m_syscall.c:703:10: warning: implicit declaration of function 'do_syscall_unix_WRK' [-Wimplicit-function-declaration] m_syscall.c:708:10: warning: implicit declaration of function 'do_syscall_mach_WRK' [-Wimplicit-function-declaration] make[3]: *** [libcoregrind_amd64_darwin_a-m_syscall.o] Error 1 make[2]: *** [all] Error 2 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2
This can be fixed by adding the line:
#define __private_extern__ extern
to the following files:
coregrind/m_syscall.c
coregrind/m_syswrap/syswrap-darwin.c
coregrind/vg_preloaded.c
(Found this by Googling for : unknown type name '__private_extern__' valgrind
)
