Gstream ARM交叉编译

我想为ARM处理器编写一个嵌入式GStreamer应用程序。我有一个飞思卡尔环境，其中包含已安装的gstream-0.10和交叉编译器工具链。 我从GStream手册中获取了第一个Hello World应用程序，并试图通过

arm poky linux gnueabi gcc video_1.c-o basic-tutorial-1

pkg-config-cflags-libs gstreamer-0.10

我的gstreamer-0.10.pc包括：

prefix=/home/.../build_mx6q/tmp/sysroots/varsommx6q/usr
exec_prefix=/usr
libdir=/home/.../build_mx6q/tmp/sysroots/varsommx6q/usr/lib
includedir=/home/.../build_mx6q/tmp/sysroots/varsommx6q/usr/include/gstreamer-0.10
toolsdir=${exec_prefix}/bin
pluginsdir=/usr/lib/gstreamer-0.10
datarootdir=${prefix}/share
datadir=${datarootdir}
girdir=${datadir}/gir-1.0
typelibdir=${libdir}/girepository-1.0
Name: GStreamer
Description: Streaming media framework
Requires: glib-2.0, gobject-2.0, gmodule-no-export-2.0, gthread-2.0, libxml-2.0
Version: 0.10.36
Libs: -L${libdir} -lgstreamer-0.10
Cflags: -I${includedir}*

汇编结果：

出了点问题，但我不明白是什么，在哪里。 我仍然需要帮助。 谢谢。

试试这个

警告说您还需要libffi和libz。你有所有的依赖项吗？是的，它是正确的。我将libffi添加到gstreamer-0.10.pc中的Requires中，并将-lz添加到命令行中。
