我正在尝试安装安装在 CentOS 5.11 系统上的 R (3.2.3) 的 igraph。错误尾部如下所示：
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: (Each undeclared identifier is reported only once
foreign-graphml.c:1330: error: for each function it appears in.)
make: *** [foreign-graphml.o] Error 1

Warning message:

XML_PARSE_HUGE 引起了我的注意。快速谷歌搜索发现它直到 libxml2 2.7.3 才出现（https://lists.nongnu.org/archive/html/igraph-help/2015-10/msg00022.html）。看来我需要为该机器构建一个较新的版本，我之前曾在下面的链接中遇到过此机器。
在 CentOS 5.X 上安装 libxml2 2.7.X
当我使用以下命令运行安装程序时
yum localinstall --nogpgcheck /usr/src/redhat/RPMS/x86_64/libxml2-2.7.8-1.x86_64.rpm
我得到了这个

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
我以为它可能需要 32 位软件包
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

我有点紧张，不敢尝试使用 --skip-broken 和 package-cleanup，因为我需要一个可靠的迁移补丁来替换更改（它在生产机器上），而我对这一切并不像我应该的那样熟悉。我可能不得不启动一个虚拟机来测试。最终，我所寻找的只是系统上运行的 R igraph 包。有人有什么想法吗？

该解决方案源自邮政作者：Radek Simko：
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
这很简单，只需从源代码进行编译即可安装。然后我可以：
install.packages("igraph")
成功登入R。
