C++ on Linux

[shebang]

I am learning C++ with Perl and I want to know how to compile C++ programs with g++... Can someone help me out?

[trickster]

try

man g++

[shebang]

it isn't there:

no manual entry for g++

[trickster]

That is strange.

Well, this is the online manual for g++

see the thing is i did install the development part of 'Drake 9.2 and GCC works but g++ doesn't work..

Go to http://gcc.gnu.org/releases.html and download the latest version.

eeee compiling gcc/g++ isn't always an easy task. I'd say reinstall g++ if it's not working. How'd you test it?

g++ a.cpp -o a
./a
?

How else would you test it? ???

Also, you can try a pre-compiled version, if compiling becomes too hard (I have never compiled it for Linux, so I do not know the best choice).

Recompiling your compiler using itself, sounds a wee bit recursive? Maybe not, but, at the very least it makes my noggin hurt.

Yeah you need gcc to compile gcc.
Chicken and egg? No, c compilers can be written in asm and then use that to compile gcc. Assembelers can be written in machine code.

Now days if you make a new processor you cross compile the compiler, no need to write machine code of an assembler first.


@chessforce
for how else he would test it I don't know, possibily wrong (use gcc not g++) that's why I posted that.
