How to install native assembler for Mac OSX?

Question

I am interested to know how can I install native assemblar (I think also known as AS) on Mac OSX Lion. Someone suggested that I can use the Xcode to do it but I didn't see any options.Terminal windows is not able to recognize AS as command right now. Can someone provide more insight on this ? I am new to Mac/Unix environment so please provide help accordingly.

Answer 1

If you have Xcode installed, then you have as .
There is no option to install specific packages from the Xcode installer.

as should be in /usr/bin/ :

ls -l /usr/bin/as

If not, you probably have a problem with your Xcode installation.

Otherwise, also check your PATH environment variable, to ensure /usr/bin/ is in the list.

echo $PATH

Answer 2

If you've installed Xcode 4.3, it doesn't install the command line tools anymore. To get them, you have to launch Xcode, go to Xcode > Preferences... > Downloads tab, then click the 'Download' button for 'Command Line Tools'. You'll need to sign in with an Apple Developer ID.

Answer 3

Using Xcode 4.6 with Command Line Utilities installed
export PATH=/Applications/Xcode.app/Contents/Developer/usr/bin:$PATH
as will execute along with the other command line utilities.
