尝试使用opengl支持编译Qt 4.8.4以安装Visit。我跑
./configure -opengl -verbose
控制台告诉我：

You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in
/home/.../Downloads/qt-everywhere-opensource-src-4.8.3/mkspecs/linux-g++-64.
所以，我查看/ mkspecs / linux-g ++ - 64，只有一个文件，qmake.conf
#
# qmake configuration for linux-g++
#
# Written for GNU/Linux platforms that have both lib and lib64 directories,
# like the AMD Opteron.
#
MAKEFILE_GENERATOR = UNIX
TARGET_PLATFORM = unix
TEMPLATE = app
CONFIG += qt warn_on release incremental link_prl gdb_dwarf_index
QT += core gui
QMAKE_INCREMENTAL_STYLE = sublib
QMAKE_CFLAGS = -m64
QMAKE_LFLAGS = -m64
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
QMAKE_LIBDIR_X11 = /usr/X11R6/lib64
QMAKE_LIBDIR_OPENGL = /usr/X11R6/lib64
我没有/ usr / X11R6目录，但X_11报告输出中一切正常。
我添加变量：
QMAKE_INCDIR_OPENGL = /usr/include/GL
QMAKE_LIBDIR_OPENGL = /usr/lib64
QMAKE_LIBS_OPENGL = -lGLU -lGL

./configure -opengl -verbose给出相同的结果
另外
glxgears
工作正常。
我做错了什么？
答案 0 :(得分：0)
我猜你可能会安装提供libGL.so.1.2.0的mesa驱动程序并更改libGL.so符号链接。
libGL.so -> libGL.so.1.2.0
libGL.so.1 -> libGL.so.331.79
libGL.so.331.79
在/ usr / lib64中，
rm libGL.so
ln -s libGL.so.1 libGL.so
会给你
libGL.so -> libGL.so.1 -> libGL.so.331.79
