Xmingwin For Cross Generation Applications

An anonymous reader writes "Xmingwin makes it practical to generate Windows programs from a Linux server. This column gives a recipe for setting up Xmingwin, outlines the most important reasons for doing so and shows you how to generate executables for multiple platforms -- including Windows DLLs -- from a single Linux source."

Re:Testing ?

If you're looking to replace Visual Studio for programs that don't rely too much on the COM wizards and such, try out Dev-C++. It's pretty fast, too, and it uses GCC :-).

Quick Note

For those of you wondering, this only works for apps that you are currently writing. It isn't going to work for just any windows app, but it's still kinda neat.

Re:Xmingwin vs gcc-mingw32

[vrmlguy]

The difference is that this is running mingwin as a cross-compiler. Yes, we've been able to produce win32 executables using mingw and gcc for years now, but that's by running everything on a Windows-based system. Now we can run the same suite of tools on a Unix-based system.

We've had this for years

I've been using a MINGW32-based linux->win32 cross-development environment for years. The same concepts apply as for cross-compiling to different hardware architectures. This is definitely not new software. With properly written makefiles, you can build to target both Linux and Win32 platforms from the same source tree and build environment. Of course you must test on both platforms, but having a setup like this definitely makes it easier to build large projects for both Windows and Linux.

Re:Usually...

[grolim13]

No, you're misunderstanding how this works. Cross-compilers have been around for ages, this one just happens to have the advantage that it inherently portable (because it is based on GCC) and targets Windows (which is phenomonally popular).

Wine works by reimplementing a part of the Windows API. Mingw32 is a compiler which takes C/C++ programs and Windows libraries and generates Windows executables. Its C/C++ support is just about flawless as it uses GCC; it can link programs against native Windows libraries just like any Windows compiler would; and it produces ordinary Windows executables.

These Windows executables, however, won't run natively on the (Linux) host machine.

Note that this is also not an automated system for writing portable programs; Xmingwin won't compile anything that wouldn't compile on a normal Windows machine. But if you have code that is portable, you can save a lot of hassle by having just one machine to build binaries for several platforms.

I'm on a crusade. I intend to post a comment like this one whenever I see anybody use "virii." Please don't interpret this comment as either endorsement of or disagreement with the parent post. Moderators: with your help, we can wipe out "virii" in our lifetime!

The plural of "virus" isn't "virii." There is no such word. The plural of "virus" is "viruses."

Here's a good explanation from cdknow.com, quoted here in its entirety because the people who most need to read this won't click on a link.

The correct English plural of virus is viruses. Please consult any good dictionary before making up words.

For the purists, in Latin, there is a rarely-used plural form:

virus, viri (neuter)

(Forms: almost always restricted to nominative and accusative singular; generally singular in Lucretius, ablative singular in Lucretius)

The point of this is that even in Latin the form "viri" is rarely used. The singular form is used in most every instance. (This is from the Oxford Latin Dictionary.)

So, when considering the Latin: "virii" is incorrect and "viri" was almost never used.

Despite the fact there was little use for the plural form, there is another reason why "viri" was rarely used. The most common Latin word for "man" is "vir" with "viri" being its plural in the form used as the subject of a sentence. Thus, since "men" as the subject of a sentence would be used far more often than "venoms" (virus means venom) the "viri" word was most commonly seen as the plural of "man."

Bottom line: Don't try to make up words using a false Latin plural form. Since the word virus in its English form is now used then the English plural (viruses) should be used.
