如何从git构建和安装最新的SimpleScreenRecorder？
我想按照开发人员的建议从git安装SimpleScreenRecorder（SSR）。 二进制版本崩溃，git版本可能已经解决了我的崩溃问题。
主页 – SimpleScreenRecorder – Maarten Baert的网站
不幸的是，我无法在Ubuntu上构建当前/最新的git版本。 可在此处找到相关说明： https ： //github.com/MaartenBaert/ssr
在这些说明中，开发人员说，“如果32位版本因库缺失而失败，但64位工作正常，请再次阅读上述说明:)。” 这似乎是我的问题，但再次阅读说明并没有澄清我的问题。 所以我在这里问。
说明：
sudo apt-get install build-essential pkg-config qt4-qmake libqt4-dev libavformat-dev libavcodec-dev libavutil-dev libswscale-dev libasound2-dev libpulse-dev libgl1-mesa-dev libx11-dev libxext-dev libxfixes-dev g++-multilib ia32-libs 如果找不到某些库的32位版本，但64位工作正常，请尝试以下方法：
cd /usr/lib/i386-linux-gnu/ sudo ln -s libGL.so.1 mesa/libGL.so sudo ln -s mesa/libGL.so libGL.so sudo ln -s libGLU.so.1 libGLU.so sudo ln -s libX11.so.6 libX11.so sudo ln -s libXext.so.6 libXext.so sudo ln -s libXfixes.so.3 libXfixes.so sudo ldconfig
开发者说：
我不知道这是否是正确的方法，但它对我有用。 如果您使用的是专有驱动程序，则libGL的位置会有所不同。 在这种情况下，使用’libGL.so’而不是’mesa / libGL.so’。 编译和安装
注意：我有一个专有（fglrx）video驱动程序。 我认为可以在这里找到它（根据我在xorg.log中看到的内容）：
/usr/lib/xorg/modules/drivers/fglrx_drv.so
但是，我需要这一步的具体帮助！
如果已将SimpleScreenRecorder作为软件包从存储库安装，则应首先卸载该版本以避免冲突。 如果不这样做，这两个版本可能会相互覆盖或使用错误版本的GLInject库。
编译和安装所有内容的最简单方法是运行：
./simple-build-and-install
这将编译64位主程序和库，然后编译32位库。 如果32位版本因库缺失而失败，但64位工作正常，请再次阅读上面的说明:)。
这似乎是我的主要问题。 我看到的错误是：
configure：错误：缺少必需的库
但是，我也看到了这个：
Detecting ffmpeg/libav ... Detected ffmpeg.
这让我感到担忧，因为ffmpeg是一个自定义编译版本，我怀疑它有所需的选项……虽然我确实启用了libx264，也许这就足够了。 我不知道。 这是相关的ffmpeg信息：

我在开发人员的帮助下完成了这项工作。 首先，开发人员说我的ffmpeg版本很好。 他还澄清说，如果simple-build-and-install的输出包括’配置32位GLInject库’（即，如果你设法在构建过程中达到这一点），则意味着64位构建部分是好。 这意味着解决方案是使用他的符号链接解决方法。
以下是我的确切步骤。
请注意，我跳过了开发人员建议的一个步骤。 我跳过了它，因为目标链接已经存在，我想在不改变链接的情况下尝试它。 （有效。）

最终结果：
Running post-install script ... Done.
所以我跑了它并没有崩溃！ :-)这是第一次重大改变。
然后我测试了它。 我使用了所有默认设置。 录制的截屏video看起来非常好!!! 我非常高兴。 该软件易于使用，效果很好。
