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

  • That looks like a problem with the gcc installation. Did you update the system? – Michael Hampton Mar 7 '14 at 14:00

    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 '14 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.
