用于R编译错误的RGL包

Question

试图在arch linux x86_64上为r编译rgl。我只复制了安装的错误部分。这是在我最近更新R.之后发生的。任何想法如何解决这个问题？

Answer 1

问题在于freetype2 2.6。降级到freetype2 2.5允许rgl正确编译。

对于archlinux，您只需运行pacman -U /var/cache/pacman/pkg/freetype2-2.5.5-1-x86_64.pkg.tar.xz即可降级到旧版程序包。

Answer 2

Freetype是可选的。禁用它是最麻烦的解决方案。

install.packages（“rgl”，repo =“http://cran.r-project.org”，configure.args =“ - disable-ftgl”）

Answer 3

对于那些来看我的人，我通过安装libfreetype6-dev在ubuntu上解决了这个问题

Answer 4

1. 从repos获取二进制文件： sudo apt-get build-dep r-cran-rgl

要么

2. 在从源代码构建rgl之前安装OpenGL。
