Subject: [PATCH] tools/thermal: tmon: include pthread and time headers in tmon.h
Date: Wed, 17 Jun 2020 16:58:08 -0700 [thread overview]
Message-ID: <20200617235809.6817-1-mmayer@broadcom.com> (raw)
Include sys/time.h and pthread.h in tmon.h, so that types
"pthread_mutex_t" and "struct timeval tv" are known when tmon.h
references them.
Without these headers, compiling tmon against musl-libc will fail with
these errors:
In file included from sysfs.c:31:0:
tmon.h:47:8: error: unknown type name 'pthread_mutex_t'
extern pthread_mutex_t input_lock;
^~~~~~~~~~~~~~~
make[3]: *** [<builtin>: sysfs.o] Error 1
make[3]: *** Waiting for unfinished jobs....
In file included from tui.c:31:0:
tmon.h:54:17: error: field 'tv' has incomplete type
struct timeval tv;
^~
make[3]: *** [<builtin>: tui.o] Error 1
make[2]: *** [Makefile:83: tmon] Error 2
Signed-off-by: Markus Mayer <mmayer@broadcom.com>

The issue was discovered cross-compiling tmon for aarch64 with musl-libc.
The build succeeds with glibc, because the required headers are included
implicitly. This is not the case with musl-libc.
