How to port OS 2 applications to Linux operating system

Free & Open.

The source code is open and can be changed at will.

Windows: Microsoft's paid operating system, which is also the operating system with the highest market share. The compatibility is very good, the software used in daily life can be run, the ecology is huge, and there are many software, but there are mixed situations.

The game support is good, the preferred operating system for playing games, the stability is relatively weak, there are more crashes, the concentration is poor, there will be a lot of pop-ups, you need to be extra careful, it is easy for your computer to lose performance.

macOS: An operating system exclusive to Apple devices, which is a mandatory operating system, and part of the money when buying an Apple computer is used to buy the system. The advantage is that it is stable, based on the UNIX kernel, basically there is no problem if it does not shut down for several months; The ecology is better, the system is not as large as the Windows system, the closed operating system, all the software on the shelves needs to be certified by Apple, and the software will be less, but because of this, the software quality is much higher, to ensure that there is no problem with daily work needs.

The security is very good, the user experience is good, the interface is beautiful, there are almost no viruses, and there is no need to worry about various pop-ups and interference. The disadvantage is that there are few games, and the support for Microsoft's software is almost cheap.**

Linux system: Maybe many people don't know much about this system, or even have not heard of it. It is a completely open-source operating system, and there are many distributions based on this system, such as:

Redhat, Mint, Ubuntu, Cetnos, etc. The biggest advantage of this system is high performance, small size, very good stability, and minimal hardware requirements. Thanks to these advantages, most Linux systems are used as server systems, and they will run stably for a long time without problems.

The biggest disadvantage is that the graphical interface is poor and there is very little software.

Difference Between Linux and Windows

Like Linux, the Windows family is a fully multitasking operating system. They support the same user interface, networking, and security. However, the real difference between Linux and Windows is that Linux is in fact a version of UNIX, and the contribution from UNIX is huge.

What makes Unix so important? Not only is Unix the most popular operating system for multi-user machines, but also that it is the basis for free software. On the Internet, a large number of free software is written for UNIX systems.

Since there are many UNIX vendors, there are many ways to implement UNIX. There is no single organization responsible for the distribution of UNIX. Now, there is a huge push for the UNIX community to standardize as an open system.

On the other hand, the Windows family is a dedicated system that controls the interface and design by the company that develops the operating system. In this sense, such a company is highly profitable because it sets strict standards for programming and user interface design, which is completely different from the open systems community. Some organizations are trying to accomplish the task of standardizing the UNIX programming interface.

In particular, Linux is fully standards-compatible.

The difference between Linux and other operating systems

Linux can coexist with other operating systems such as MS-DOS, OS 2, Windows, etc., on the same machine. They are both operating systems and have some commonalities, but they have their own characteristics and differences from each other.

At present, the operating systems running on PCs mainly include Microsoft's MS-DOS, Windows, Windows NT, and IBM's OS 2. Early PC users generally use ms-dos, because this operating system does not have high requirements for the hardware configuration of the machine, and with the rapid development of computer hardware technology, the hardware equipment is getting lower and lower, people can relatively easily improve the hardware configuration of the computer, so they began to use windows, windows

NT and other operating systems with a graphical interface. The more detailed differences of Linux still need to be really learned by yourself to understand, you can go to see Linux-related books such as "Linux Should Be Learned This Way".

There are two ways, one is to install it with an rpm package, and the other is to install it with a medium source code tar package.

What are you linux?

ubuntu？debian？

Common method (source**package):

1.Unpack. 2.After the command line enters the directory, run the"config"or"configure"

Some programs have requirements for the environment or can set certain settings, please see the specific instructions or online prompt 3After success, make

After success, make install

1.ISO file for your favorite Linux system under the web;

2.Buy a blank*** disc and burn the ISO on it;

3.Insert the disc into the optical drive and restart the computer;

4.There is an installation prompt at the bottom when starting up (the words "F12 to setup"), Lenovo computers are F12 keys to enter the installation interface, and other computers have corresponding.

Prompt; It is recommended to use Ubuntu, which is very helpful for beginners to learn and be interested in Linux, and to install and Windows

Just as simple and harmonious;

The computer has window, unix

Windows is divided into Windows98, Windows XP, Windows7, and Windows8

UNIX is divided into Linux HP-UX AIX phones with iOS, i.e. Apple's system.

And Android, Symbian.

Haven't tried to install so many systems. Theoretically, yes. It's just that different systems require different formats of hard drives.

The person who asked the question is really brainless, why do you come up with this kind of question.

DLinux developed rapidly, and by the end of 1993 and the beginning of '94, Linux was finally born! Linux is already a full-fledged operating system.

d. Late 1993 and early 1994.

Since 1983, the GNU project has been dedicated to the development of a free and complete UNIX-like operating system, including software development tools and applications. By the time the Linux kernel was released in 1991, GNU had almost completed the development of all the necessary software in addition to the system kernel. Thanks to the efforts of Linus Torvalds and other developers, GNU components can run on top of the Linux kernel.

The entire kernel is based on the GNU General Public License, also known as the GNU General Public License (GPL), but the Linux kernel is not part of the GNU project. In March 1994, when it was released, Marc Ewing founded Red Hat Software, which became one of the most prominent Linux distributors.

There's really nothing interesting about such a topic. I'm afraid Linus himself doesn't know.

I don't know how many kinds of operating systems there are, but China generally uses the following more: Windows system, Mac (Apple), Unix, Linux, etc. The most is of course the Windows series.

There are windows98, me, 2000, xp, 2003, and a new 2008Of course, there used to be NT, 95, 97 and so on, but apart from XP and 2003, few people use them now.

Windows has DoS, Windows, Windows 95, Windows 98, Windows 98 SE, and Windows ME

Windows, Windows NT, Windows 2000, Windows XP

Windows Vista, Windows 7, and other operating systems such as Linux, Redflag, OS 2, Unix, Xenix, etc.

The Linux operating system is a computer operating system. The name of the kernel of the Linux operating system is also "Linux". The Linux operating system is also the most well-known example of the development of free software and open source**.

The main benefits of Linux are open source, security, and stability.

For programmers, understanding the internal ** and running structure of the system is one of the ideas to understand the system and write higher quality programs, and now the development and use of Linux is becoming more and more common, especially in server applications (you are familiar with Gogle, Yahoo are commercial software packages of Linux platform), you can imagine Linux applications.

Windows is a non-open source commercial software, and it is difficult for you to get its source code, and you can't modify its content (otherwise you will have to wait for a lawsuit). This presents a lot of challenges for application development.

Also, Linux is not pure command-line software.

The command line is the foundation, and then runs the GUI platform on top of it, commonly such as KDE Gnome and XFACE (lightweight).

Linux is an operating system for business offices if you want to use it at home.

It is recommended to use the home or professional version of Windows XP, which comes with some commonly used small software, and network compatibility is also good.

Windows XP is a very user-friendly operating system.

It's pretty much the same as the other versions.
