在安装了graphviz之后，在R当中安装Rgraphviz。命令：

不知道如何解决。在网上搜索了两天之后，并在邮件组里分问，分析认为是动态链接库的问题。解压原代码安装包，测试：
[ouj@qiuworld ~]$ R CMD ldd /usr/local/lib/libgvc.so.6 linux-vdso.so.1 => (0x00007fff173fc000) libxdot.so.4 => /usr/local/lib/libxdot.so.4 (0x00002b5c100e0000) libgraph.so.5 => /usr/local/lib/libgraph.so.5 (0x00002b5c102e4000) libcdt.so.5 => /usr/local/lib/libcdt.so.5 (0x00002b5c104f0000) libpathplan.so.4 => /usr/local/lib/libpathplan.so.4 (0x00002b5c106f5000) libdl.so.2 => /lib64/libdl.so.2 (0x00002b5c10914000) libexpat.so.0 => /lib64/libexpat.so.0 (0x00002b5c10b18000) libz.so.1 => /usr/lib64/libz.so.1 (0x00002b5c10d3a000) libm.so.6 => /lib64/libm.so.6 (0x00002b5c10f4f000) libc.so.6 => /lib64/libc.so.6 (0x00002b5c111d2000) /lib64/ld-linux-x86-64.so.2 (0x000000349cc00000) [ouj@qiuworld ~]$ sudo R CMD ldd Rgraphviz/src/Rgraphviz.so [sudo] password for ouj: linux-vdso.so.1 => (0x00007fff58b40000) libgvc.so.6 => not found libc.so.6 => /lib64/libc.so.6 (0x00002aacd51ae000) /lib64/ld-linux-x86-64.so.2 (0x000000349cc00000) |
果然。可是没有办法使用export 为sudo 输出共亨链接库，只好先使用
[ouj@qiuworld ~]$ sudo LD_LIBRARY_PATH=/usr/lib:/usr/local/lib R CMD INSTALL Rgraphviz_1.30.1.tar.gz ... |
先安装上。接下来的问题是如何将LD_LIBRARY_PATH=LD_LIBRARY_PATH:/usr/local/lib写给每个用户，并在每次登录的时候都可以正常使用。否则在使用Rgraphviz包时，都需要LD_LIBRARY_PATH=/usr/lib:/usr/local/lib R来启动R。
[ouj@qiuworld ~]$ sudo vi /etc/ld.so.conf.d/Rgraphviz.conf |
在文件中写入一行：
/usr/local/lib |
然后保存退出。
[ouj@qiuworld ~]$ sudo /sbin/ldconfig |
而后退出ssh，再次登录

一切ＯＫ。
