c++ - Mujoco : Missing shared libraries with Simulate. cpp 入门步骤

Question

我正在尝试从 ubuntu 17.04(最新版本)安装 Mujoco(但没有成功)。

说明网址:Getting started

版本:mjpro150 linux 和/或 mjpro140 linux

我已经有了许可证。

按照以下步骤:

把mjkey.txt和激活码放在bin = ok

运行 simulate.cpp = 错误

情况:

目录

wil@Ophelia:~/Documents/mjpro150/bin$ ls
basic       libglewegl.so     libglfw.so.3         mjkey.txt  test
compile     libglewosmesa.so  libmujoco150nogl.so  record
derivative  libglew.so        libmujoco150.so      simulate

路径

wil@Ophelia:~/Documents/mjpro150/bin$ pwd
/home/wil/Documents/mjpro150/bin
wil@Ophelia:~/Documents/mjpro150/bin$ LD_LIBRARY_PATH=/home/wil/Documents/mjpro150/bin
wil@Ophelia:~/Documents/mjpro150/bin$ echo $LD_LIBRARY_PATH
/home/wil/Documents/mjpro150/bin

Mujoco的命令步骤和ERROR

wil@Ophelia:~/Documents/mjpro150/bin$ ./simulate
./simulate: error while loading shared libraries: libmujoco150.so: cannot open shared object file: No such file or directory
wil@Ophelia:~/Documents/mjpro150/bin$ ./simulate.cpp
bash: ./simulate.cpp: No such file or directory
wil@Ophelia:~/Documents/mjpro150/bin$ ./simulate ../model/humanoid.xml
./simulate: error while loading shared libraries: libmujoco150.so: cannot open shared object file: No such file or directory

正在尝试编译？! (出入门)

问题:有人知道我是如何进行的吗？

Answer 1

试运行

LD_LIBRARY_PATH=。 ./模拟 ../model/humanoid.xml

作为一个整体(即在 shell 中按回车键之前将所有这些字符粘贴在同一行中)作为 pwd 下的 bin，或至少

export LD_LIBRARY_PATH=/home/wil/Documents/mjpro150/bin

在调用 ./simulate 之前。您必须导出一个环境变量，以使其对从(相同)shell 启动的另一个程序可见。
