構成：エラー：Cコンパイラはビルド中に実行可能ファイルを作成できませんRubyソースから
Stackoverflowで同様の質問をいくつか確認しましたが、まだ回答が見つかりません。
ここで説明するように、Rubyソースからビルドしようとしています： https://www.Ruby-lang.org/en/installation/#building-from-source
ここで私が得ているもの：
ubuntu@saucy1:~/Ruby-2.1.1$ ./configure

checking Host system type... x86_64-unknown-linux-gnu

更新しました：
システムは新品で、Ubuntu 13.10のクラウドイメージを使用しています。ダウンロードは http://uec-images.ubuntu.com/saucy/current/saucy-server-cloudimg-AMD64-disk1.img
このクラウド仮想マシンをオープンスタックソフトウェアで作成しました。
そして、私はこのコマンドでgccをインストールしました：
Sudo apt-get install gcc
Gccの現在のバージョン：
#gcc -v
Using built-in specs.

configure: exit 1
configure.logには2つの明らかな問題があります。
gcc: error: missing argument to '-march='
gcc: error: unrecognized command line option '-V'
-marchは、特定のアーキテクチャを選択する必要があります。 -march=i686または-march=x86-64
gcc -Vは、複数のバージョンがある場合に特定のgccバージョンを選択する方法です。これはおとりですが、configureは一連のオプション（--version -v -Vなど）を使用して反復し、Cコンパイラのバージョンをログに記録できることを確認します。それはgccか何かです。
CFLAGSおよびCC環境変数を確認します。
echo CFLAGS=$CFLAGS
echo CC=$CC
の出力
gcc -dumpmachine
gcc -v
1つの可能性は、コンパイラーのデフォルトをオーバーライドする疑わしいspecsファイルです。実行できる場合は、実行してください。
gcc -dumpspecs
*cc1_cpu:段落を含めます。
あなたがそれを実行できない場合、私はマイケル・ハンプトンに同意します、何かが非常にひどく壊れています。
わかりました、gcc -vは「組み込みの仕様を使用しています。 "と言っています。つまり、specsファイルが壊れていないか、コンパイラが壊れているか、環境に問題がある可能性があります。あなた可能性があります-marchを含めるようにCFLAGSを設定することでこれを修正できます：
export CFLAGS="-march=x86-64 -mtune=x86-64"
（それが機能する場合は、-march=native -mtune=nativeを試してください）
local_cpu_detect()（gcc内部）を使用した-march=native検出が誤動作している可能性がありますが、実際にはそれがどのように発生するかはわかりません（gcc/config/i386/driver-i386.c）。これはcpuidと他の制限されている可能性のある命令を呼び出します（万が一あなたのVMにいくつかの追加のセキュリティ機能が備わっていますか？）。 "Ubuntua/Linaro 「gccが作ったのかもしれないけど。
（Linaroはクロス開発ツールを提供しますが、gccはクロスコンパイラではなく、--target=x86_64-linux-gnuでビルドされています）
通常、-march=nativeを渡すと、検出内容を確認できます。
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 [...]
Ruby-2.1.1のconfigureスクリプトdoesは-marchを使用しますが、アトミックな組み込み（__sync_val_compare_and_swap）を検出するためだけであり、とにかくそれほど遠くまで到達することはありません。
