**而不是降低投票可能expression如何改善职位。 谢谢！
我试图安装在CentOS 5.11系统上安装的R（3.2.3）的igraph。 错误的尾部看起来像：
foreign-graphml.c:65: warning: excess elements in struct initializer foreign-graphml.c:65: warning: (near initialization for ‘blankEntityStruct’) foreign-graphml.c: In function ‘igraph_read_graph_graphml’: foreign-graphml.c:1330: error: ‘XML_PARSE_HUGE’ undeclared (first use in this function) foreign-graphml.c:1330: error: (Each undeclared identifier is reported only once foreign-graphml.c:1330: error: for each function it appears in.) make: *** [foreign-graphml.o] Error 1 ERROR: compilation failed for package ‘igraph’ * removing ‘/usr/lib64/R/library/igraph’ The downloaded source packages are in ‘/tmp/RtmpBDaixr/downloaded_packages’ Updating HTML index of packages in '.Library' Making 'packages.html' ... done Warning message: In install.packages("igraph") : installation of package ‘igraph’ had non-zero exit status XML_PARSE_HUGE卡在我身上。 Quick Google发现，直到libxml2 2.7.3（ https://lists.nongnu.org/archive/html/igraph-help/2015-10/msg00022.html ）才显示出来。 看起来我需要为在本网站上遇到的机器构build一个更新的版本，之前在下面的链接。
在CentOS 5.X上安装libxml2 2.7.X
当我运行与它的安装
yum localinstall --nogpgcheck /usr/src/redhat/RPMS/x86_64/libxml2-2.7.8-1.x86_64.rpm
我得到这个尾巴

我想也许它需要一个32位的软件包
rpmbuild --target i386 -ba /usr/src/redhat/SPECS/libxml2.spec yum localinstall --nogpgcheck /usr/src/redhat/RPMS/i386/libxml2-2.7.8-1.i386.rpm
哪个尾巴

我有点紧张，试图使用–skip-broken和包清理，因为我需要有一个坚实的迁移补丁到/从变化（它是在生产机器上），我不是所有这一精通正如我应该的那样。 我可能不得不启动虚拟机来击败。 最终，我所需要的是在系统上运行的R igraph软件包。 任何人有任何想法？
解决scheme来自Radek Simko的一篇文章 ：
wget ftp://xxmlsoft.org/libxml2/libxml2-2.7.8.tar.gz tar -xvf libxml2-2.7.8.tar.gz cd libxml2-2.7.8 ./configure make sudo make install
这是一个简单的从源代码编译安装。 那么我可以：
install.packages("igraph")
在R成功。
