如何使用 GStreamer 编译 C/C++ 程序

Question

我正在尝试编译此代码：

#include <stdio.h>
#include <stdlib.h>
#include <gst/gst.h>

int main (int   argc,
      char *argv[])
{
  const gchar *nano_str;
  guint major, minor, micro, nano;

  gst_init (&argc, &argv);

  gst_version (&major, &minor, &micro, &nano);

  if (nano == 1)
    nano_str = "(CVS)";
  else if (nano == 2)
    nano_str = "(Prerelease)";
  else
    nano_str = "";

  printf ("This program is linked against GStreamer %d.%d.%d %s\n",
          major, minor, micro, nano_str);

  return 0;
}

当我在终端中使用此命令时：

libtool --mode=link gcc `pkg-config --cflags --libs gstreamer-1.0` -o main main.c

我收到此错误：

Package gstreamer-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gstreamer-1.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gstreamer-1.0' found
libtool: link: gcc -o main main.c

而这个错误：

main.c:3:21: fatal error: gst/gst.h: No such file or directory

但是我已经用apt-get安装了GStreamer 1.0和libtool。你有什么想法我应该从哪里开始？我挖了整个互联网搜索答案，但没有人有答案。

Answer 1

gst/gst.h由 提供libgstreamer1.0-dev。安装它：

sudo apt-get install libgstreamer1.0-dev

在 Code::Blocks 中，您可以设置自定义包含位置和链接器标志。在“项目”菜单中，单击“构建选项”：
