I've checked a number of similar questions on stackoverflow but haven't found an answer yet.

I am trying to build Ruby from source as describe here: https://www.ruby-lang.org/en/installation/#building-from-source

Here what i am getting:

ubuntu@saucy1:~/ruby-2.1.1$ ./configure
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking for gcc... gcc
checking whether the C compiler works... no
configure: error: in `/home/ubuntu/ruby-2.1.1':
configure: error: C compiler cannot create executables
See `config.log' for more details

Updated:

The system is brand new and i am using a cloud image of Ubuntu 13.10, Downloaded from http://uec-images.ubuntu.com/saucy/current/saucy-server-cloudimg-amd64-disk1.img

I made this cloud virtual machine with open stack software.

And i installed gcc via this command:

sudo apt-get install gcc

Current version of gcc :

#gcc -v

Using built-in specs.

Here is Updated config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.69.  Invocation command line was

Not only your compiler, but your entire system environment, seems to be broken. How did your system get into its current state? –  Michael Hampton Mar 7 at 13:53

That looks like a problem with the gcc installation. Did you update the system? –  Michael Hampton Mar 7 at 14:00
    
I ran sudo apt-get update and i post output of screen to question. –  Pradeep Gupta Mar 7 at 14:05

Yeah, I think your cloud image is hopelessly broken. I suggest you file a bug on launchpad, and in the meantime, install Ubuntu yourself. –  Michael Hampton Mar 7 at 14:06

There are two obvious problems in configure.log:

gcc: error: missing argument to '-march='
gcc: error: unrecognized command line option '-V'

-march should be selecting a specific architecture, e.g. -march=i686 or -march=x86-64

gcc -V is a way of selecting a specific gcc version when you have more than one, that's a decoy here though: configure is iterating through a set of options (--version -v -V etc.) to make sure it can log the version of the C compiler, be it gcc or something else.

Check your CFLAGS and CC environment variables,

echo CFLAGS=$CFLAGS
echo CC=$CC

the output of

gcc -dumpmachine
gcc -v

One possibility is a suspect specs file overriding the compiler defaults, so run (if you can)

gcc -dumpspecs

and include the *cc1_cpu: paragraph.

If you cannot run that, then I concur with Michael Hampton, something is very badly broken.

Ok, gcc -v says "Using built-in specs.", that means you don't have a broken specs file, you might have a broken compiler, or something up with your environment. You might be able to fix this by setting CFLAGS to include -march:

export CFLAGS="-march=x86-64 -mtune=x86-64"

(If that works then try -march=native -mtune=native )

Its possible that -march=native detection with local_cpu_detect() (gcc internal) is malfunctioning, though I really can't see how that happens (gcc/config/i386/driver-i386.c). This calls cpuid and other possibly restricted instructions (any chance your VM has some additional security features in place?) I'm not familiar with any changes that the "Ubuntua/Linaro" gcc may have made though.

(Linaro provide cross-development tools, but your gcc is not a cross-compiler, it's built with --target=x86_64-linux-gnu)


Normally, if you pass -march=native you can see what it detects:

gcc -v -march=native -o x hello.c 2>&1 | less
...
COLLECT_GCC_OPTIONS='-v' '-march=native' '-o' 'x'
/usr/local/libexec/gcc/i686-pc-linux-gnu/4.7.3/cc1 -quiet -v hello.c -march=core2 [...]

The ruby-2.1.1 configure script does use -march, but only to detect an atomic builtin (__sync_val_compare_and_swap), it never gets that far anyway.
