c - 使用 Cmake 构建 Gstreamer mpegts 项目

Question

我们正在尝试使用 Gstreamer 的 mpegts 插件使用以下 Gstreamer 示例代码https://gstreamer.freedesktop.org/documentation/mpegtsmux/mpegtsmux.html?gi-language=c录制视频流。当我们使用一切按预期编译代码时gcc mpegtstest.c -o mpegtstest `pkg-config --cflags --libs gstreamer-1.0 gstreamer-mpegts-1.0` -v ，程序记录没有问题。我们现在尝试使用cmake和编译代码make。cmake正确生成但因make错误而失败。 /usr/bin/ld: cannot find -lgstreamer-mpegts-1.0.

在网上搜索并尝试了一些在网上找到的不同的东西（比如这里）并查看 Github 代码后，我们不知道为什么或如何修复它。非常感谢任何建议或帮助。提前致谢。

解决方案 感谢 nega 的评论和解决方案，更改include_directories(${GSTREAMER-MPEGTS_INCLUDE_DIRS})为include_directories(${GSTREAMER_MPEGTS_INCLUDE_DIRS})工作。

根据您的cmake输出，我猜您正在使用FindGStreamer.cmake WebKit 的 cribbed版本。如果是这种情况，您要使用的变量是GSTREAMER_MPEGTS_INCLUDE_DIRS. 请注意变量名称中缺少连字符。

如果不是这种情况，message()请在使用变量之前使用一个简单的语句来在该cmake步骤中向您显示它的值。

在你的CMakeLists.txt：

message("GMID: ${GSTREAMER_MPEGTS_INCLUDE_DIRS}")
include_directories(${GSTREAMER_MPEGTS_INCLUDE_DIRS})
target_link_libraries(${CMAKE_PROJECT_NAME} gstreamer-mpegts-1.0)

在你的外壳中：

$ cmake ../src |grep -i ^gmid
GMID: /usr/local/Cellar/libffi/3.3_2/include;/usr/local/Cellar/gst-plugins-bad/1.18.3/include/gstreamer-1.0;/usr/local/Cellar/gstreamer/1.18.3/include/gstreamer-1.0;/usr/local/Cellar/glib/2.66.7/include;/usr/local/Cellar/glib/2.66.7/include/glib-2.0;/usr/local/Cellar/glib/2.66.7/lib/glib-2.0/include;/usr/local/opt/gettext/include;/usr/local/Cellar/pcre/8.44/include

另一个简单的调试步骤是grep运行后去缓存cmake。
