在 CentOS 上安装 Octave-4.0.0 会出现 QtOpenGL 链接错误

在 CentOS 上安装 Octave-4.0.0 会出现 QtOpenGL 链接错误

我正在尝试在 CentOS 6 集群上安装 Octave-4.0.0。Octave 有 20 多个依赖项,不清楚每个依赖项要使用哪个版本。由于yum只有 Octave-3.4.3,我安装了 Octave-3.4.3,yum希望它能让我正确安装大多数依赖项。我还必须安装(通过yum

arpack-devel-3.1.3-1.el6.x86_64
fltk-devel-1.1.10-1.el6.x86_64
gl2ps-devel-1.3.5-1.el6.x86_64
glpk-devel-4.40-1.1.el6.x86_64
qhull-devel-2003.1-14.el6.x86_64
qrupdate-devel-1.1.2-1.el6.x86_64
qscintilla-devel-2.4-1.el6.x86_64
suitesparse-devel-3.4.0-9.el6.x86_64

以及来源

pcre-8.36

我运行自动配置:

./configure JAVA_HOME="/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.79.x86_64/"  CPPFLAGS="-I/home/path/to/user/local/include"  --prefix=/home/path/to/user/local/  --with-blas=/usr/lib64/atlas/libf77blas.so.3 --with-lapack=/usr/lib64/atlas/liblapack.so.3

似乎一切都很好,然后当我运行时,make它花了大约 30 分钟进行编译,然后失败:

在 auto conf 生成的 Makefile 中,它似乎应该正确链接到 Qt 库,即

.
.
.
QT_CFLAGS = -DQT_SHARED -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include/QtNetwork -I/usr/include/Q     tOpenGL
QT_CPPFLAGS = -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include/QtNetwork -I/usr/include/QtOpenGL
QT_LDFLAGS =
QT_LIBS = -lQtNetwork -lQtOpenGL -lQtGui -lQtCore   -lqscintilla2
.
.
.

在 /usr/lib64/ 中我检查了 Qt 库的内容

$ for i in *Qt*.so.4.6.2; do echo $i; nm -C -D $i | grep -i checkWindowRole; done
libQt3Support.so.4.6.2
                 U QObjectPrivate::checkWindowRole()

libQtXmlPatterns.so.4.6.2
                 U QObjectPrivate::checkWindowRole()
libQtXml.so.4.6.2

并且似乎在 内QWidgetPrivate::checkWindowRole()声明了(如果我解释nm正确的话?)libQtGui.so.4.6.2。此库已链接到(参见上文)

问题:我该如何解决这个问题并libQtOpenGL看到正确的库?

答案1

事实证明,我在用户空间本地安装了一款软件,它在 中安装了一些库~/local/lib。在该目录中,该软件安装了libQtCore.so.4libQtGui.so.4。这是这里安装的唯一 Qt 相关库。同样,我设置了

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/path/to/user/local/lib

这意味着链接器在位于 中的库之前找到了这些库/usr/lib64。更改 $LD_LIBRARY_PATH 以使其不再指向~/local/lib,让链接器完成其工作并解决了我的问题。
