让我描述一下我的问题。到目前为止，我正在构建请求libbot2库的 MPNet。
我已经安装了以下需求库：
GLib 2.0+
CMake
LCM (http://lcm.googlecode.com)
Java (Sun JDK or OpenJDK strongly preferred)
Python
GTK+ 2.0+ (required by bot2-vis)
OpenGL (required by bot2-vis)
GLUT
PyGTK
libglib2.0-dev
cmake
sun-java6-jdk | default-jdk | openjdk-6-jdk
python-dev
python-gtk2
libgtk2.0-dev
mesa-common-dev
libgl1-mesa-dev
libglu1-mesa-dev
freeglut3-dev
libjpeg-dev
这是我的部分环境设置。
OS: Ubuntu 18.04
freeglut3-dev is already the newest version (2.8.1-3)
libxi-dev is already the newest version (2:1.7.9-1)
libxmu-dev is already the newest version (2:1.1.2-2)
binutils is already the newest version (2.30-21ubuntu1~18.04.3)
libglu1-mesa-dev is already the newest version (9.0.0-2.1build1)
libgtk2.0-dev is already the newest version (2.24.32-1ubuntu1)
libjpeg-dev is already the newest version (8c-2ubuntu8)
freeglut3-dev is already the newest version (2.8.1-3)
libgl1-mesa-dev is already the newest version (19.2.8-0ubuntu0~18.04.3)
libglib2.0-dev is already the newest version (2.56.4-0ubuntu0.18.04.6)
mesa-common-dev is already the newest version (19.2.8-0ubuntu0~18.04.3)
LCM version 1.4.0
当我使用sudo make时，我得到了这个错误。我发现我无法成功构建bot2-vis这个阶段。
