Installing software on Linux


Installing software on Linux.
Years ago was more complicate install software in linux, in the begin we had the code source and we had compile it. How compile it?. Compile the source code have his advantages, the software is optimized for own computer but the installation isn' t ever easy. We have the name_program.tar.gz to decompress it. tar zxvf name_program.tar.gz Now is create the folder, we enter in it. cd name_program The first is read the documentation that is in the folder, the name normally is README, if we haven't instruction (it's rare) find the configure file and execute it. ./configure If you haven't the configure file it isn't problem, we are able to do without the last instruction. The ./configure is to optimize the software to the hardware but any program are "optimize" by default. make This instruction is to compile the program, it get the information of the makefile that is a file included in all name_program to compile all the .c .h ...... After compile it we need to install definitively an last instruction. make install In any cases isn't need do the make. The installation is completed. Errors? of course!. If your hardware isn't compatible to the software you'll look any errors when you do the ./configure. After of the ./configure If you haven't all the dependencies when you'll compile it, you can see the dependencies that need you, how libinit.3.4.so I explain bellow how find and installs its.

Now we can install Red Hat Packets (.rpm) that are more easy and is turn into in a standard together with the Debian packets (.deb).
When we get the packets of the internet we have look the extension, this is i386 or i586 or i686 .rpm or .deb it depends of your computer and your linux distribution.

Debian have an method more easy and not complicate to install software register.
