I have a question related to makefile. I'm new to makefile and I'm in the process of writing a makefile for my RBT build. I have multiple source files and when I compile them I will get multiple object files (one object file for each source file). I'm having problem in creating a target for each object file with out hardcoding the object file names. I read the list of source file names from another make file. Assume the variable SRC_NAMES contains list of source file names (say test1.c test2.c test3.c). Now I want to create target for each objects for it (say test1.obj test2.obj test3.obj). Currently I have written some thing like below,
This is not working. Since OBJS_LIST contains many object names, compilation action is repeated for many times for the target $(OBJS_LIST). My question is how to split the obj target into multiple targets without hard-coding the target obj names?
Thanks,
Anand

At my company, we build some stuff using a makefile. While the makefile script is running, a developer may check in a newer version of a source file. The problem is, when we next run the make command, the target file isn't rebuilt, because the date of the target is after the dependency.

Hi All
I need to parse the target
something like:
ifeq '$@' 'first'
echo 1 $@
endif
ifeq '$@' 'second'
echo 2 $@
endif
The thing is to be able compare the target string to any string and then do the commands
Thanks a lot

Hi all,
I've a makefile which has this line:
@touch $@
I know $@ is for representing the target. But I don't know what's the @ preceding the touch.
Can anyone help me?

Hi,
I wanted to know whether there is any way to specify in a makefile how to compile sources from a directory directly by giving the directory path name instead of mentioning each and every source file name.

Hi!
I've got a build process where scripts create multiple targets from their sources. But here I'm running into a conceptual problem of GNU make: If one has multiple targets in a dependency, make applies the rules once for every target that is out of sync - which is correct for normal... (3 Replies)

wdmd
WDMD(8) System Manager's Manual WDMD(8)NAME
wdmd - watchdog multiplexing daemon
SYNOPSIS
wdmd [OPTIONS]
DESCRIPTION
This daemon opens /dev/watchdog and allows multiple independent sources to detmermine whether each KEEPALIVE is done. Every test interval
(10 seconds), the daemon tests each source. If any test fails, the KEEPALIVE is not done. In a standard configuration, the watchdog timer
will reset the system if no KEEPALIVE is done for 60 seconds ("fire timeout"). This means that if single test fails 5-6 times in row, the
watchdog will fire and reset the system. With multiple test sources, fewer separate failures back to back can also cause a reset, e.g.
T seconds, P pass, F fail
T00: test1 P, test2 P, test3 P: KEEPALIVE done
T10: test1 F, test2 F, test3 P: KEEPALIVE skipped
T20: test1 F, test2 P, test3 P: KEEPALIVE skipped
T30: test1 P, test2 F, test3 P: KEEPALIVE skipped
T40: test1 P, test2 P, test3 F: KEEPALIVE skipped
T50: test1 F, test2 F, test3 P: KEEPALIVE skipped
T60: test1 P, test2 F, test3 P: KEEPALIVE skipped
T60: watchdog fires, system resets
(Depending on timings, the system may be reset sometime shortly before T60, and the tests at T60 would not be run.)
A crucial aspect to the design and function of wdmd is that if any single source does not pass tests for the fire timeout, the watchdog is
guaranteed to fire, regardless of whether other sources on the system have passed or failed. A spurious reset due to the combined effects
of multiple failing tests as shown above, is an accepted side effect.
wdmd will exit if a watchdog driver is not loaded.
wdmd cannot be used on the system with any other program that needs to open /dev/watchdog, e.g. watchdog(8).
Test Source: clients
Using libwdmd, programs connect to wdmd via a unix socket, and send regular messages to wdmd to update an expiry time for their connection.
Every test interval, wdmd will check if the expiry time for a connection has been reached. If so, the test for that client fails.
(Other test sources such as scripts executed each test interval may be added in the future.)
OPTIONS -D Enable debugging to stderr and don't fork.
-H num Enable (1) or disable (0) high priority features such as realtime scheduling priority and mlockall.
Default 1.
