使用OpenSG渲染

Question

我这里有点状况。我正在尝试和OpenSG一起工作。我下载了这个包，并按照安装文件中的说明进行了安装。然后我也安装了它的系统依赖库。现在我尝试构建它的教程，但它显示了错误。它显示glut未配置，但我在配置glut库的同时启用了它，并安装了所有依赖的包和库。我不明白问题出在哪里。尝试制作OpenSG教程时显示的错误如下：

如果有人能帮我找到解决方案，我将不胜感激。

本教程的makefile如下所示：

LIBTYPE ?= dbg

# set the path to the installed osg-config executable here
# if you don't set it, the makefile tries to guess

# than one system is configured from one dir. Just for the 1.0

endif

当我再次尝试配置和编译opensg，并尝试编写本教程时，它显示了以下错误，这与之前的错误略有不同。我以前遇到过这个错误，但它已经改变了。错误：

Answer 1

看这一行：

/usr/bin/ld: cannot find -lXmu

这意味着您错过了系统上的一个库。该库的名称是libxmu.您需要为其安装开发包。如果您使用的是ubuntu，可以使用以下命令：

apt-get install libxmu-dev
