特にCmakeを利用している環境では手軽にWebAssemblyを試しづらい。
（例えばserverside-swifをビルドする際、cmake3が必要でWebAssemblyと環境を分けたいといったケースが考えられる。）
どうしても、手元のMacの環境上では実行しにくいというケースもあるだろう。
Linux上での実行方法はEmscripten SDKのページに書かれている。
ただしUbuntuベースの手順となっている。
https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
この投稿はCentOS7上でのWebAssembly実行方法として書きまとめる。
上記ページ等には明記はされていないが、webserverである
emrun自体はVirtualBOX上で実行し、ブラウザ自体はWindowsやMac上のブラウザを利用する事ができる。ここでは、VirtualBox上のcentos-release-7-3.1611.el7.centos.x86_64で実行した。
# rpm -qa centos-release
centos-release-7-3.1611.el7.centos.x86_64
Virtual Boxは以下のバージョンを使用した。
バージョン 5.1.22 r115126 (Qt5.6.2)
環境構築の為の作業は割と手軽なのでお薦めする。
（LLVM等rpmでインストールしたもので動作した。）
自己責任でお試しいただきたい。
なおVirtualBox上のCentOSでemsdkのビルドにあたりCPUcoreは複数あった方が早く終わる。
ただし、CPUcoreを増やすとメモリも多く必要とする。
（メモリをキャッシュとして使われる様なので、回避策はあるのかも知れない。）
メモリが少ないとリンカが途中で停止する場合がある。
具体的には以下のメッセージが表示され停止する。
fatal error: ld terminated with signal 9 [Killed]
これは、README.mdに記載がある通りメモリ不足に起因する。git cloneでemsdkのソースを取得した際に一度目を通した方がいい。
何回かビルドたところ目安として、1Coreあたり3G程度のメモリがあった方がいいのだろうか。（必ず比例する訳でもない。）
1Coreでも2時間程度のビルド時間となる。
ハードディスクは35G程度は欲しい。
おおまかな作業としては、
https://developer.mozilla.org/ja/docs/WebAssembly/C_to_wasm
にある通り。
注意点としてはCentOS7ではepelにて提供されている、cmake3を利用する。
また、その際cmake3に対しcmakeとしてシンボリックリンクを張る。
（シンボリックリンクという回避策は快くは思わないが、emsdk内の表記をcmake3に変更する事の方がより難しいと思う。）
なおcmake2系で実行した場合、途中で以下のメッセージが表示され継続できない。
CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
CMake 3.4.3 or higher is required. You are running version 2.8.12.2
また、cmake3に対しcmakeというシンボリックリンクを張らない場合は以下のfailとなり中断してしまう。Running CMake: ['cmake', '-G', 'Unix Makefiles', '-DCMAKE_BUILD_TYPE=RelWithDebInfo', '-DPYTHON_EXECUTABLE=/usr/bin/python', '-DLLVM_TARGETS_TO_BUILD=X86;JSBackend', '-DLLVM_INCLUDE_EXAMPLES=OFF', '-DCLANG_INCLUDE_EXAMPLES=OFF', '-DLLVM_INCLUDE_TESTS=OFF', '-DCLANG_INCLUDE_TESTS=OFF', '-DLLVM_ENABLE_ASSERTIONS=ON', '/usr/local/src/emsdk/clang/fastcomp/src']
Installation failed!
selinuxは事前に無効とした。ファイル、/etc/selinux/configのSELINUXの箇所は
SELINUX=disabled
とした。
VirtualBox再起動後
getenforce
で確認する。
# getenforce
Disabled
実際の環境構築手順としては以下の様になる。
# yum --disablerepo=\* --enablerepo=base install -y git
# yum --disablerepo=\* --enablerepo=base install -y gcc
# yum --disablerepo=\* --enablerepo=base install -y gcc-c++
# yum install -y epel-release
# yum --disablerepo=\* --enablerepo=base,epel install -y cmake3
# ln -s /usr/bin/cmake3 /usr/bin/cmake
# cd /usr/local/src
# git clone https://github.com/juj/emsdk.git
# cd emsdk
# ./emsdk install sdk-incoming-64bit binaryen-master-64bit
# ./emsdk activate sdk-incoming-64bit binaryen-master-64bit
サンプルなので/usr/local/src以下にソースを展開したが、当然他のディレクトリで良い。最後に環境構築変数を設定するシェルを実行する。
# source ./emsdk_env.sh
ここまでの手順でコンパイル環境は整う。次の投稿にてサンプルにある、hello worldを動かしてみる。
念の為、yumにてrpmをインストールした際のインストールログも記載しておく。 今後の動作しない場合等の参考となればと思う。
