It seems that the different libc (musl) which Alpine Linux uses produces
different errors than the usual glibc. This patch fixes most include
errors. Two errors are not yet resolved on Alpine Linux's libc (musl):
* proc_parse.c: In function 'parse_posix_timers':
proc_parse.c:2125:34: error: 'SIGEV_THREAD_ID' undeclared (first use in this function)
timer->spt.it_sigev_notify = SIGEV_THREAD_ID;
proc_parse.c:2125:34: note: each undeclared identifier is reported only once for each function it appears in
Seems difficult to fix as including <linux/signal.h>, which provides
this #define, generates more different error messages related to
time.h and linux/time.h collisions. It is not yet clear if additional
guards would help in the header files.
* fsnotify.c: In function 'open_by_handle':
fsnotify.c:107:9: error: implicit declaration of function 'open_by_handle_at' [-Werror=implicit-function-declaration]
return open_by_handle_at(fd, arg, O_PATH);
The function open_by_handle_at() is not provided by Alpine Linux's
libc (musl).
This patch resolves the following errors/warnings and has been tested on
RHEL7(x86_64/powerpc64le) and Fedora 24:
