Setting up a C++ compiler for Windows Command-Line

[apomb]

Well, im just trying to get a leg- up for next semester ... I am eventually going to learn it from school, but i have not had a good time figuring out C++ code. I really want to learn it, but i can wait for instruction on that language.

[wtd]

Feel free to ask any questions you have in C/C++ Help and I'll be happy to answer them if I can.

well, when i compile and run the simple "hello world" program, nothing happens (wil only run a bunch of words in the bottom of the "output" area, but no "hello world")

im on Dev C++... what am i missing

The IDE is getting in the way. You need a simpler setup.

Which OS are you running?

Do a search for "g++.exe" on your computer. Find the directory that that program lives in. Copy it.

This is from the Java setup page, slightly modified.

From the start menu, choose programs, accessories, system tools, and system information. This brings up a window titled "Microsoft Help and Support". From here, choose the tools menu, then select the system configuration utility. Click the environment tab, select PATH and press the edit button. Now add the location of g++.exe to your path as described in step b above. After you've added the location of g++.exe to your PATH, save the changes and reboot your machine when prompted.

and this does ....

Once you've done that, open a command prompt and type

code:

C:\> g++

You should be greeted by something like:

code:

g++: no input files

If you are, then congrats, you have a working C++ compiler you can use from the command-line.

Compiling a source file then is as simple as:

code:

C:\> g++ my_program.cpp -o my_program.exe

And running it is:

code:

C:\> my_program

Of course you have to cd to the directory where your source file is, first.

it says "page cannot be displayed"! dammit, and the path is correct too, hmm
hey, now theres a black screen, but it only flashes for like a nano second, then i closes

How far are you getting? Where are you running into the problem?

[apomb]

where do i type it, in an internet explorer console or DOS?

DOS.

[apomb]

alright, got that, now it has already

code:

C:\WINDOWS>

and then "bad command or file name"

ill try rebooting again ...

[wtd]

Not sure since I'm using 2000 Pro, but try typing "path" at the prompt and seeing if the string you see includes the path to g++.exe.

Note: you shouldn't include the "g++.exe" in that path. Just the directory path.

heres what is on screen right now:

code:

Bad command or file name C:\WINDOWS>path PATH=C:\WINDOWS\COMMAND\g++.exe

its there, now what? ...
