ubuntu14.04:用于qt开发的opengl

半天以来我尝试让 qt-creator 进行编译...但出现错误。

当我开始编译 qt-creator 的标准图形项目(刚刚创建了这个空项目并尝试编译)时,这是我得到的输出:

15:49:05: Running steps for project colour-picker...
15:49:05: Skipping disabled step qmake.
15:49:05: Starting: "/usr/bin/make"

Sp 我认为缺少 gl 库。(通过编译控制台项目,它可以工作。所以我可以看到生成的空窗口。)如果我搜索 gl 库:

find -name *gl.so*
./home/fabian/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libfltk_gl.so.1.1
./home/fabian/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/usr/lib/x86_64-linux-gnu/libfltk_gl.so.1.1
./home/fabian/.local/share/Steam/steamapps/common/GarrysMod/bin/libtogl.so
./home/fabian/.local/share/Steam/steamapps/common/Team Fortress 2/bin/libtogl.so
./usr/lib/xorg/modules/libglamoregl.so
./usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqminimalegl.so
./usr/lib/x86_64-linux-gnu/libwayland-egl.so.1
./usr/lib/x86_64-linux-gnu/libcogl.so.15.3.1
./usr/lib/x86_64-linux-gnu/libwayland-egl.so.1.0.0
./usr/lib/x86_64-linux-gnu/libcogl.so.15
./usr/lib/compiz/libopengl.so

.. 找到了,但是我认为在错误的目录和名称下(最后一个条目(libopengl.so)?我是对的吗?如果是这样该怎么办?

另外,如果我在控制台中输入一些内容,会发现:

ldconfig -p | grep libGL.so
    libGL.so.1 (libc6,x86-64) => /usr/lib/nvidia-352/libGL.so.1
    libGL.so.1 (libc6) => /usr/lib32/nvidia-352/libGL.so.1
    libGL.so (libc6,x86-64) => /usr/lib/nvidia-352/libGL.so
    libGL.so (libc6) => /usr/lib32/nvidia-352/libGL.so

为了理解:链接到 gl 库的指令来自哪里?我找不到它

谢谢你的帮助

答案1

似乎我可以通过删除来解决问题:

sudo apt-get purge libcheese-gtk23, libclutter-1.0-0, libcheese7

虽然 skype 或 steam 等都需要这些库。所以我不得不重新安装 skype 并重新配置 steam。

此后一切又恢复正常
