Bodhi Linux and Pixie Renderer install under gnome boxes

Ubuntu系のLinux 64bitでPixie Rendererを動かしました。
RIBが使える唯一のRenderMan互換rendererになるかもしれません。
Dispersion.jpg
Fedora28のgnome boxesにBodhi Linux5.0 64bitをインストールしました。
ダウンロードしたのは、bodhi-5.0.0-apppack-64.iso (1.5GB)
Pixie Rendererをビルドしました。
Pixie Rendererをダウンロードしてきます。
https://sourceforge.net/projects/pixie/

解凍します。
$ tar xvf Pixie-src-2.2.6.tgz
$ cd Pixie/
$ ./configure
...
ellipsis (省略)
...
errorが出ますので、以下、いくつかインストールします。
管理者権限で、
$ sudo -i

~# apt install update

~# apt install bison
~# apt install flex
~# apt install build-essential

~# apt install libtiff-dev
~# apt install libpng-dev

*****************************************
次に、以下のpatchをあてます。https://sourceforge.net/projects/pixie/のticketにあります。
ファイル名pixie-2.2.6-gcc6.patchをダウンロードします。
https://sourceforge.net/p/pixie/patches/23/
上記から入手してください。
上のパッチを解凍したPixie/src/commonに保存します。
以下を実行します。

$ cd src/common
$ patch < pixie-2.2.6-gcc6.patch
patching file global.h

パッチをあてないでmakeすると以下のようなエラーが出ます。
