I'm trying to get the mkbundle tool working on Mac OS X 10.7. I installed XCode 5, a handful of different Mono versions, going from v2 to v4. Everytime I try to compile my code I get a
sh: as: command not found
When I try to find this command, its not on my system either. After googling, which is pretty hard as "as" is filtered out for being too generic, I simply cannot find a solution to this. The best resource I can find states its the native compiler of XCode, but I have that installed...
Could someone assist?
You are looking for the Xcode assembler:
> man as
NAME
as - Mac OS X Mach-O GNU-based assemblers
SYNOPSIS
as [ option ... ] [ file ... ]
DESCRIPTION
The as command translates assembly code in the named files to object code.
If no files are specified, as reads from stdin. All undefined symbols in
the assembly are treated as global. The output of the assembly is left in
the file a.out by default.
The program /usr/bin/as is actually a driver that executes assemblers for
specific target architectures. If no target architecture is specified, it
defaults to the architecture of the host it is running on.
Do you have Xcode and it's cmd line tools installed?
> which as
/usr/bin/as
> file `which as`
/usr/bin/as: Mach-O 64-bit executable x86_64
Located in Xcode.app:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../libexec/as/x86_64/as
Xcode cmd-line tools:
Assuming you have installed the 'free' Xcode package via the App store, the cmd line tools can be installed via "xcode-select". Drop into a term window and:
xcode-select --help
Usage: xcode-select [options]
Print or change the path to the active developer directory. This directory
controls which tools are used for the Xcode command line tools (for example,
xcodebuild) as well as the BSD development commands (such as cc and make).
Options:
-h, --help print this help message and exit
-p, --print-path print the path of the active developer directory
-s <path>, --switch <path> set the path for the active developer directory
--install open a dialog for installation of the command line developer tools
-v, --version print the xcode-select version
-r, --reset reset to the default command line tools path
xcode-select --install
Once installed, you will get updates via the App Store

I want to use gcc and gcn in 2 separate steps to compile and link C program.
The problem I got is that linker does not find basic C functions like pop, push, isValid, etc,etc,etc
I do not want to use sofisticated packages at this point like Xcode available on my platform.
When trying to run gcc :
gcc -v function#1.c -o function#1
I got back from the system:
xcrun: error: active developer path ("/Applications/Xcode.app/Contents/Developer") does not exist
Use sudo xcode-select --switch path/to/Xcode.app to specify the Xcode that you wish to use for command line developer tools, or use xcode-select --install to install the standalone command line developer tools.
See man xcode-select for more details.
Any help is greatly appreciated.
I have two different Xcode version installed on the same mac (Xcode 4 and Xcode 5). Xcode 4 is in the Applications folder.
So whenever I build any projects from the terminal, naturally it compiles by using Xcode 4. Is there any way to use Xcode 5 (which is in desktop) to build a project from the terminal?
I think the command xcode-select is here for this precise reason.
Usage: xcode-select [options]
Print or change the path to the active developer directory. This directory
controls which tools are used for the Xcode command line tools (for example,
xcodebuild) as well as the BSD development commands (such as cc and make).

-h, --help print this help message and exit
-p, --print-path print the path of the active developer directory
-s <path>, --switch <path> set the path for the active developer directory
-v, --version print the xcode-select version
-r, --reset reset to the default command line tools path
I had the same problem. I had changed the command-line tools option in Xcode's preferences. Here you can choose which version of Xcode, you wanted to use.
I'm in the process of installing XCode Command Line Tools onto OSX 10.9 Mavericks
I did a successful install XCode:
$ xcode-select -p
/Library/Developer/CommandLineTools
However when I type in either $ clang or $ gcc it returns:
clang: error: no input files
If you just type the command without any input files, then as commented, the compiler reports an accurate error message.
But if you have an existing project, then you can see that same "clang: error: no input files" message when:
you move your folder/files after making the project
one of your files isn't recognized by the XCode project
your project pre-compile header settings is wrong (wrong prefix):
In Xcode "Build settings" reviews the value for "Prefix header".
It seems to me that you have it set to "MySecondTabbApp/MySecondTabbApp-Prefix.pch" and it should be just "MySecondTabbApp-Prefix.pch"

The error was that I was running through steps to configure ruby and was directed to instructions on another page that just stated to check for $ gcc instead of $ gcc --version.
Obviously new to coding, trying to learn more.
Try gcc -v.
I am on a Mac (Mavericks) and that worked for me. It will tell you which version you are using (and you will know it is installed).
I faced the same issue. Type in xcode-select --install. It will work.
Another possibility: double check how the file in question is added to the xcode project. In my case, the file was set to "relative to group" instead of "relative to this project" and it was causing this error.
just type gcc -v which will spit an output specifying the prefix flag with which gcc was installed and the LLVM version as well. Specifying gcc on the command line without an option will report the issue you say it is reporting because its not able to find a file to compile using gcc.
I was seeing this error while setting up a React Native project. Here is what worked for me.
sudo xcode-select --switch /Applications/Xcode.app
I have a xcode project that was created for osx snow leopard. All it was required to be built was to run
xcodebuild
from the command prompt. I am now trying to build the same project on OS X 10.7 and the following error happens when I run the same command
/Users/repo/trunk/main.c:31:10: fatal error: 'stdlib.h' file not found
What exactly is going on? I tried to follow the instructions from this question but stdlib.h is still missing.
How can I fix this problem?
Likely you are getting bit by the repackaging of everything inside /Applications/Xcode.app starting with Xcode 4.3. In Unix-like installations stdlib.h usually lives in /usr/include and your project likely expects it to be there as it was pre-Xcode 4.3. You can fix this by installing the command line tools, which includes the tools and the associated headers and libraries in their standard location.
The easiest way to install the command line tools is from inside Xcode. In the Xcode Preferences select the "Downloads" pane and then the "Components" tab. Push the "Install" button next to "Command Line Tools".
You need to run xcode-select to tell xcodebuild and xcrun which Xcode you want to use.
See this manpage.
I've installed XCode v3.1.3 and am having difficulties using the rumored GCC that is installed along with it. -- I'm certainly able to use the XCode IDE to compile my programs but would like the flexibility of also using the command line...
Where's GCC?
Look in /Developer/usr/bin
The most likely explanation is that when you installed the Developer tools you unchecked "UNIX Development Support", so the command line tools were never installed. Delete your /Developer/ directory and do a clean install of the tools; make sure to select "configure" during the installation process and ensure that the appropriate items are checked.
In /usr/bin you should find gcc-4.0 and gcc-4.2 and then there will be a symbolic link gcc which points to one of these (usually gcc-4.2).
As always, you can find out where any available command in your PATH is located using which, e.g.
$ which gcc
