系统范围的 libxml2 不工作,从源代码编译在配置中失败
System wide libxml2 not working, compilation from sources failes in configure
系统范围 libxml2
我想在 IBM BlueGene/Q 安装的 JUQUEEN 超级计算机上编译 Chroma 物理模拟套件。 RedHat Linux 上的前端 运行 6. 架构在前端和计算节点上都是 PowerPC 7。它们使用的 CPU 不同,前端有 IBM Power 740,计算节点是 IBM Power A2 芯片。使用 mpigcc
和 mpig++
等编译器自动为计算节点交叉编译。
可以使用 module
将现代版本的程序加载到路径中。存在对其他两个必须编译的库的依赖性。我现在已经完成了 qmp
。 qdpxx
也依赖于 libxml2
,这就是我卡住的地方:
chroma --- qdpxx --- qmp
\-- libxml2
在我的 Fedora 24 工作站上,我可以使用 libxml2
的系统范围安装编译 qdpxx
。我刚刚安装了 RPM 包 libxml2
和 libxml2-devel
,并且不必为 qdpxx/configure
.
指定任何 -with-libxml2=DIR
参数
在超级计算机前端,我得到这个:

看来我刚刚丢弃了所有其他库可以驻留的路径,因此不再构建任何内容。
尝试创建从 /usr/lib/libxml2.so.2
到 $HOME/libxml2.so
的符号链接,但添加 -L$HOME
也没有成功。
正在尝试从 Git
编译 libxml2
在这一点上,我停止追求系统范围的安装,并尝试从 Git 存储库安装 libxml2
。所以我克隆了存储库并输入 ./autogen.sh
。这个失败的说法:
Checking zlib
./configure: line 12546: syntax error near unexpected token `Z,zlib,'
./configure: line 12546: ` PKG_CHECK_MODULES(Z,zlib,'
那里的 autotools 自称是 2.69 版。这是安装在大学集群上的相同版本(它也失败了)。在我的 Fedora 24 工作站上安装了相同的版本,但 ./autogen.sh
仅 运行 就创建了一个 Makefile
.
我现在有点迷茫。如果 libxml2
的构建脚本在 ppc64
RedHat 和 amd64
Debian 大学集群上失败但在我的 x86_64
Fedora 笔记本电脑上失败,是否存在错误?
如何让 qdpxx
的 configure
脚本使用 libxml2
的系统范围安装?它确实已经使用 xml2-config
:
提取了正确的标志
configure: libxml2 compile flags: -I/usr/include/libxml2
configure: libxml2 libraries flags: -lxml2 -lz -lm
如何进一步编译我的程序?
运行ln -fs /usr/share/aclocal/pkg.m4 .
在源码目录下configure
找到PKG_PROG_PKG_CONFIG
。但是,仍然存在语法错误。重新运行 autoreconf
创建了一个 configure
文件,现在不再有语法错误。
