I downloaded g++ and put

Code:

g++ password.cpp -o RandomPswrd

^ this in the termional but I get a bash error. The .cpp is in the gcc-4.40 folder. I just dragged the password.cpp into the folder. How can I compile these files?

do you get a specific bash error?

-bash: g++: command not found

???

That's after I put in the code the RandomPswrd can be anything right?

That error usually shows up if either:

1) The path to the executable is not in the exported path
2) The software hasn't been installed.

Just out of curiosity, have you installed g++, or the xcode developer pack? AFAIK, installing OSX by itself doesn't install the compilers. I think a version of XCode may be on the OSX disc that you can install, but you might as well get the most current version from apple and register as a developer. It's free and once properly installed, you should have no problems.

GCC/G++ has to be compiled (the irony).

Download the developer tools from the Apple developer site or install Xcode/dev tools from your OS X installation disc to get an installed binary of GCC. Your best bet is to get it from the Apple dev site though as Xcode will be a newer version there.

bump

I downloaded xcode but now I get

i686-apple-darwin9-g++-4.0.1: password.cpp: No such file or directory
i686-apple-darwin9-g++-4.0.1: no input files

so is password.cpp in the directory you're running the compile from?

What do you mean? It is in a gcc-4.40 folder.

you have to be in the directory your source is in to compile it.

So, for instance.. if your password.cpp was in your home directory under a folder called source.. you'd have to

cd ~/source
g++ password.cpp -o RandomPasswd

for it to compile. Or, you'd have to specify the path to the source like

g++ /path/to/password.cpp -o RandomPasswd

It can't guess where your source is.

Ok, so I put a folder called source in finder > steven (right below "desktop") and inside the source folder is the password.cpp and now I get this:

password.cpp: In function ‘int main()’:
password.cpp:8: error: ‘srand’ was not declared in this scope
password.cpp:18: error: ‘rand’ was not declared in this scope

Now you have programatic errors

Try gdb password.cpp

I'll give you a hint - you're missing an include file

Sub-Zer0 · Sub-Zer0 #13 (**permalink**)

04-23-2009, 09:49 PM

what include file?
