在CentOS上使用OpenGL支持從源代碼編譯Qt 4.8.3

Question

嘗試使用opengl支持編譯Qt 4.8.4來安裝Visit。 我跑

./configure -opengl -verbose

控制台給了我：

 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，我看看/ mkspecs / linux-g ++ - 64，只有一個文件，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

我沒有/ usr / X11R6目錄，但X_11報告輸出中的一切正常。

我添加變量：

QMAKE_INCDIR_OPENGL   = /usr/include/GL
QMAKE_LIBDIR_OPENGL   = /usr/lib64
QMAKE_LIBS_OPENGL     = -lGLU -lGL

./configure -opengl -verbose給出相同的結果

此外

glxgears

工作正常。

我究竟做錯了什么？

Answer 1

我想你可能會安裝提供libGL.so.1.2.0的mesa驅動程序並更改libGL.so符號鏈接。

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

會給你

libGL.so -> libGL.so.1 -> libGL.so.331.79
