让我描述一下我的问题。到目前为止，我正在构建请求库的 MPNet libbot2。
我已经安装了需求库如下：
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
当我使用时sudo make，出现了这个错误。我发现我无法成功构建bot2-vis这个阶段。

我该如何解决这个问题？谢谢

Ubuntu 18.04：构建请求 libbot2 的 MPNet：libbot2 错误
sudo apt install openjdk11-jdk
cd lcm-1.4.0/ && mkdir build && cd build/
cmake -DLCM_ENABLE_TESTS=NO -DCMAKE_INSTALL_PREFIX=/usr ..
make
.
[ 79%] Built target lcm-java
.
[ 90%] Built target lcm-python

注意：LCM_ENABLE_TESTS是默认选项，在 95% 时会导致错误 → test/java/hamcrest-core-1.3/org/hamcrest/core/AllOf.java 。因此-DLCM_ENABLE_TESTS=NO，即在上述构建示例中禁用测试。
*** 使用更高版本的libbot2 https://github.com/ripl-ttic/libbot2
git clone https://github.com/ripl-ttic/libbot2.git
cd libbot2/
sudo make BUILD_PREFIX=/usr ## no errors
