2019-08-06os_mon: Fix sscanf to use %llu instead of gnu specific %LuLukas Larsson
For instance musl does not recognize the %L modifier.
2018-09-29Make Erlang's cpu_sup function better on AndroidAlexander Clouter
Due to `/proc` restrictions in newer Android releases enforced by SELinux, Erlang needs a fix so that it can get some basic CPU stats (use the `sysinfo` syscall rather than reading `/proc/loadavg`).
2016-05-17os_mon: Fix compile error on FreeBSDSverker Eriksson
implicit declaration of function 'EXIT_WITH' Move code chunk up a bit to #define EXIT_WITH before it's used.

2016-05-06os_mon: Implement cpu_sup:util/0,1 on OSXYuki Ito
cpu_sup:util/0,1 works on OSX as well.
2016-05-04Fix compilation on SUN/SPARC by including <stdlib.h>Kostis Sagonas
The combination of the use of the exit() function without including <stdlib.h> together with the option -Werror=implicit-function-declaration causes the compilation (and the 'make') to fail on SUN/SPARC with gcc 4.9.3.

* aw/native-cpu_sup/OTP-12730: erts: Fix configure.in os_mon: rename send() to sendi() in cpu_sup.c os_mon: cpu_sup should use native sysctl/libkvm calls on BSD
2014-12-29os_mon: rename send() to sendi() in cpu_sup.cAlex Wilson
Without this, cpu_sup.c won't compile on FreeBSD, as the name overlaps with the send() socket call.
2014-12-29os_mon: cpu_sup should use native sysctl/libkvm calls on BSDAlex Wilson
This avoids forking off with os:cmd every time we just want to collect the load averages. riak does this every second, which results in a lot of unnecessary load.
2014-12-11Fix compile breakage on OpenBSDAlex Wilson
Some of the structs and functions needed by memsup.c are in vmmeter.h on OpenBSD, too.

Enable a cross compile Erlang/OTP platform to Android or Raspberry PI using Android NDK. Port emulator and core application to support target HW platform. Exclude any add-on services required for OTP platform deployment into target hardware due to device fragmentation and jail-break requirements. * fix erts/emulator/beam/sys.h Disable redefinition of __noreturn macro * port erts/emulator/sys/unix/erl_child_setup.c Use techniques proposed by https://code.google.com/p/erlang4android to access system properties * fix erts/emulator/sys/unix/erl_unix_sys_ddll.c The static linking of emulator cannot find dlerror(), dlopen() symbols * port erts/emulator/sys/unix/sys.c make path to shell configurable at build time * port erts/etc/common/Makefile.in disable librt for *-linux-androideabi * port erts/lib_src/pthread/ethread.c Use techniques proposed by https://code.google.com/p/erlang4android to disable emulator crash if kernel threads are on.

2013-09-02Fix broken cpu_sup:nprocs and others on Solaris 64-bitSimon Cornish
The correct kstat datatype for nproc & avenrun_* is ui32, not ulong. Under 64-bit OTP builds garbage was returned because the wrong datatype was used. This patch correcs the datatype. It also adds an additional check in the test case for a slightly less insane return value.

With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.

2011-08-08*/c_src/Makefile*: Support parallel makeBjörn Gustavsson
Create directories first, not within implicit rules. If two 'install' instances runs at the same time attempting to create a directory, one of them may fail with an "File exists" error. I tried to use order-only prerequisites to create the directories, but run into two problems: First, order-only prerequisites are only implemented in Make 3.80 and later. Second, on a computer running Solaris/Intel 2.8 (with Make 3.80), order-only prerequisites seemed to work like ordinary prerequisites, causing targets to be re-built if the timestamp for the directory changed. Therefore, using a shell command to run mkdir seems to be the more portable solution.
