General :: Makefile - Break Out The Compilation Into Individual Gcc Commands For Each C File
Apr 28, 2010
I have ~200 c files in my makefile[$(SRCS)], and it compiles all of the files using a single gcc command. So each time I make a change in one c file, it ends up re-compiling all the files, then linking to make the
binary. How can I break out the compilation into individual gcc commands for each c file, so that make checks the timestamp and accordingly compiles only the modified files.
I'd like to create a target named "debug" or something similar which will use some special optimization flags useful when debugging (for example -ggdb). At the moment my makefile is neat (which I like) and looks like
I just downloaded slackware 13.1(x86) and i'm trying to compile ndiswrapper-1.56 using the slackbuild from slackbuils.org and i'm getting this error:
Code:
Makefile:535: /usr/src/linux-2.6.33.4/arch/i486/Makefile: No such file or directory make[2]: *** No rule to make target `/usr/src/linux-2.6.33.4/arch/i486/Makefile'. Stop. make[1]: *** [modules] Error 2 make: *** [all] Error 2
I am new in perl, i have a question i.e 'How to read individual logs from linux server into another log file using perl script', I need to capture the individual logs from different paths and output the result of those log files and store to a file in another location.These Logs are generated in Linux Server..
I have a large text file with three columns. I'm trying to write a PERL script that splits the file up based on the value of the 3rd column. So every time the third column reads 0, a new file is created and all the data up until the next 0 is found is written to that new file. This should happen over and over until the initial file has been entirely split up.
I am trying to use a software package written in ANSI C. It has a makefile which has to be executed first.
As soon as I execute it I get messages like: line i: command not found.
Commands for which I am getting errors :
CC = /usr/bin/gcc GCCFLAGS = -c -Wall ROOTDIR = .
My gcc compiler is located in the above directory only. In ROOTDIR also I tried giving the path in which all the required files & folders are present but still I get the command not found error in all the lines.
My new VPS is running Debian 5.0 (bash 3.2.29), and some commands seems to be missing. For example the ps command is not here, neither is ls (but dir works). Is there a package missing or what's the deal?
I have a few questions to ask, so please pardon me
1) How to check for https in commands config file for Nagios? I only know how to check for http, not sure for https.
2) The log file in Nagios, is it possible to extend Nagios's plugins (or are there already have plugins existed) so that we could actually make use of the log file to check for status of each and every services in different hosts, instead of looking through the log file manually which can be very time-consuming if the list is very long.
When I try execute a variety of basic commands (including ps, ls, ifconfig, locate), I receive the error 'no such file or directory'.
Here are some suggestions that I've found online, that I have tried without success: I did a 'whereis ps' and found the file in the /bin/, and have checked that '/bin' appears when I do 'echo $PATH' I did a filesystem check which showed my hard drive as being clean I tried doing a 'sudo chmod 777 ps' but was told that I dont have permission. I don't think permissions for these files would have changed though (and I can't check as I can't run the 'ls' command).
i am working on some kind of PBX and i have list of telephone numbers inside a file, i have to insert these numbers into the correct command and then telnet to a remote server and execute these commands. i can read the telephone numbers and insert them into the command with no problem, but when i try to insert these commands into the send i face problem. here is the basic code
i can make external loop inside the Bash which read the input file and issue the command and then telnet and execute, but this will make the script connects and disconnects again for each line which cause high load on that server and hardwar problem. i am wondering if there is an option inside the expect interperter which makes the send read directly from a file... somthing like this:
I am very new to Linux and trying to learn the shell scripting. Just to know is there any client in linux which does the same task as FTPS on windows. FTPS on windows can read series of FTP command from a txt file and execute them. Is there any way to do that same task, i mean reading series of ftp commands from a txt file, on linux suing shell or perl (any module)?
since a recent upgrade to Mandriva 2010.1 I am not able to 'sudo' as administrator or when I use the 'root' password. I am the only user on this machine (Dell Inspiron 530S multi-booted with Window's Vista Home Premium, Ubuntu 10.4, and Mandriva 2010.1). I can get into the 'Manage Users' section of the control center by authenticating as 'root' but I can't access 'sudoers file' from command line.
whenever i am trying to compile a c++ program i am getting the following error sample.cpp:1: fatal error: iostream.h: No such file or directory compilation terminated
I'm buying this unit from deal extreme: it's a bitorrent downloader, with NAS capability. I'm interested in sharing an external HD in it, with media and backup purposes. I'm afraid of energy problems (don't know if this is the correct term), corrupting my mounted drives (like after a storm), so I thought about buying an UPS that sends a "signal" to my Linux box, and a script in my Linux box would unmout everything to avoid problems.Do this "UPS signal" feature exists? Do you have model suggestions?
I'm trying to get my new Wireless USB dongle to work with Xubuntu 9.10 Karmic Koala. I've extracted the .rar file that was on the drivers CD that came with the dongle. According to the ReadMe....
The Model Name is: RT2870 Wireless Lan Linux Driver Driver Name: rt2870.o/rt2870.ko Hardware: Ralink 802.1n Wireless LAN Card Description: This is a linux device driver for Ralink RT2870 USB ABGN WLAN Card. My issues:
1. I do not see the driver file anywhere in the folder contents... I suppose that I have to "build" it. 2. In the makefile the chipset is default set to "CHIPSET = 3070" & the folder that holds all the extracted files is named 2008_1128_RT3070_Linux_STA_v2.0.1.0 so I'm confused as to whether this dongle has a 2870 or 3070 chipset inside. Does it matter? 3. Sorry, I'm a bit of a n00bster when it comes to all this, but I'm having some problems with the build instructions. It reads:
Sometimes I type 'sudo su - user' in linux and then realise I'm typing it from an application account rather than a user account. I want to ctrl+c to abort the password entry. When I do this, it always freezes for a couple of seconds before it aborts the process and returns me to the shell.
