A lot of other people are getting into the details of more complex makefiles and a lot of the complexity that comes with them. I typically use makefiles for a completely different reason:
I don't want to remember anything.
Even if your project is really boring and simple, and you don't use makefiles "correctly":
gcc main.c -o project
I don't ...
As opposed to what?
Suppose you have a program that you have split into two files,
which you have imaginatively named file1.c and file2.c.
You can compile the program by running
cc file1.c file2.c -o yourprogram
But this requires recompiling both files every time,
even if only one has changed.
You can decompose the compilation steps into
cc -c file1.c
Even with small project it can be helpful keeping the dependency logic under control and builds automated. I also used it to trigger installs and deinstallations, so it was a main switch resetting the stage.
If you link your app from 2 sources (.c files) , you do not need to recompile each file, but only the changed one if you are using make.
Also, I will give you example from BSD world. They have framework of system-based Makefiles. They provide you paths to system directories and have targets to install your software and manual pages.
For example, you just ...
You should install manpages-dev, which provides manpages for system calls and a number of library functions, and the -dev and (if any) -doc packages for the libraries you’re developing with.
For kernel functions you should install linux-manual-4.9 (or whichever version is appropriate); this is where you’ll find man 9 fls.
To find manpages in general, ...
If you are running from an SD card, then mmcblk0 represents the SD card.
This Linux command will flash from the SD card to internal memory:
busybox dd if=/dev/mmcblk0 of=/dev/mmcblk1 bs=64K conv=noerror,sync
The following options work:
I just installed the stable version of OmniOS Community Edition. It was just as easy to install and use as Linux distros and BSDs. It comes with an SSH server. Vim is available out of the box. You can install git and gcc via sudo pkg install which works just like other package managers. Use pkg search to find more packages.
Assuming you tried to perform a yum install, i.e. yum install somepackage, and yum repos.d does not have an entry for EPEL (extra packages and dev stuff) so yum is letting you know it has no idea where to look.
Configure the files in dir: /etc/yum.repos.d/ Each file in that dir are for contacting different yum repositories.
This link shows you how to add ...
The simplest way is to create selfsigned certificate, add it to the web server. And do not forget to add it to the browser (to avoid) warning messages.
You can check here how to do this
You can do that in one command:
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days
You can also add -nodes (short for no DES) if you ...
Example Makefile for my very small project: getPixelColor
It does exactly what its name says, taking two optional arguments, the coordinates.
I especially like the way things get dependent there.
