China DOS Union

Please help everyone. I used to do win graphical programming. Recently, due to work matters, I need to run my program under DOS, but the company's is 16DOS. Please give me a download.

Because C++ seems to only be able to compile 32DOS programs~~~
Thank you everyone first~~~

Recompile with djgpp.

What is digpp?

I still want to know the download address of 32-bit FreeDOS

FreeDOS 32 is still in the prealpha stage and is not usable at present. You can search for the download address on SourceForge.

djgpp is a DOS port of GCC. It uses the DPMI interface to enter the 32-bit protected mode under 16-bit DOS and access the 4GB flat address space. DPMI was set by Microsoft and several major manufacturers back then. Besides djgpp, Watcom and DMC also support DPMI.

There are also 16-bit C++ compilers under DOS, such as TC++, BC++, MSC, etc.

If you want to run Win32API/ABI applications directly under DOS, try HX DOS Ext

I really didn't expect that DOS still has a place to be useful these days, heh. What exactly is that program?

Is it VC++ 6.0? There must be something wrong with your program itself? I remember there is an option to write a console program in VC++. If you directly use that to compile, the problem should not be too big.

That's what the poster above said

tigerpower:
There are many DOS-based embedded systems. All gate machines in Shanghai Metro are based on the 486 STD of DOS.

272922032:
The console program compiled by VC6 is based on the Win32 API and cannot be directly used under real DOS.

What the person upstairs said is very correct. My program is no problem. But it can only run on 32-bit DOS. Thank you everyone for your help!! I thought Freedos32 could be used. It seems a bit difficult. If it could, I propose to ask the company to replace all HDDs with FreeDOS. Now it's not possible. Are there any better suggestions from others.. As for me, I'm working on PE at ASUS.

The latest test version of HX DOS Extender (updated on 2006.5.14) has made quite a few progressions now. For example, the Win32 Console version of UPX 2.0 and its compressed programs, XCOPY32 in Win9x that supports long filenames, etc., can all run normally. Therefore, it should still be good to give it a try. Your Win32 Console program may very likely run directly under pure DOS through it. The following is the download address of the latest test version of HX provided by its author for me:

The update speed of HX is really fast. It's quite hard to keep up with his updates, heh heh.

486 is pretty good, we can only use 186....
Also, what is PE,楼主?

Another question to the thread starter: Why must it be 32-bit? Does it require more memory?

Hehe.

There are two types of PE engineers, Process Engineer (process engineer, i.e., process engineer) and Product Engineer (product engineer); the former is responsible for the design and implementation of product manufacturing processes; the latter is responsible for product design and development. As for Project Engineer (project engineer), it is mainly responsible for project development progress, finance, focusing on project coordination and project management. Generally, it is not called PE, but called project manager.

And I am the Product Engineer among them. Responsible for product design and development! The reason for why 32-bit is because later everyone can program to run directly in the WINDOWS interface, and after testing, it is applied in 32-bit DOS, which will reduce some troubles, right!!

Thanks to Administrator Wengier for providing the HX DOS download address, I will try it!! Also, I don't quite understand how to install it. Is there an introduction in the forum post??
After unzipping the compressed package, there are two directories, one BIN and one DOC. How to install it??

copy-run doesn't need to be installed. If you want to run it in another directory, just set the path variable. For details, please refer to the documents in the doc directory.
