使用 OpenSG 渲染

Question

我这里有点情况。我正在尝试与 OpenSG 合作。我下载了该软件包并按照安装文件中的说明安装了它。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，但它显示错误。它说 lut 未配置，但我在配置它时启用了 glut 库，并安装了所有依赖包和库。我不明白问题是什么。 尝试制作 OpenSG 教程时显示的错误如下：

如果有人可以帮助我找到解决方案，我将非常感激。

本教程的 makefile 如下：

# use debug or opt libs?
LIBTYPE ?= dbg

# set the path to the installed osg-config executable here
# if you don't set it, the makefile tries to guess
# e.g. if you installed in /usr/local:
# OSGCONFIG := /usr/local/bin/osg-config

# use OSGPOOL if set

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

        OSGCONFIG := $(OSGCONF)
    endif
endif

    OSGCONF := $(strip $(OSGCONF))

endif

# ok, give up

当我再次尝试配置和编译 opensg 并尝试制作本教程时，它显示以下错误，该错误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

这意味着您的系统上缺少一个库。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，则可以使用以下命令来完成此操作：

apt-get install libxmu-dev
