我正在使用我的工具链为 ARM 编译 gst-plugins-bad。我编译了构建它所需的所有内容，包括 gstreamer、libmms 等...并将与 pkg-config 相关的标头、库和文件放入我的 sysroot 中。
当我配置 everyrhin 似乎没问题，但尝试编译结果为：

它似乎正在尝试链接到我的桌面 libxml2。为什么它没有链接到我的工具链中包含所有符号的工具链？
你的configure脚本支持autoconf交叉编译吗？ 在configure.in中，调用AC_PROG_CC后shell变量cross_compiling的值是多少？
如果设置为 no，那么 makefile 是否设置为使用交叉编译器？
要设置这些，您可以在手册中覆盖它们或使用环境变量，例如 下面的例子
导出 CC=arch-gcc 导出 CXX=arch-c++ 导出 arch-ld 导出 AR=arch-ar 导出 AS=arch-as 导出 NM=arch-nm 导出STRIP=拱形条
如果设置为 yes，则检查 makefile 中专门用于 libxml 的包含路径。
在 ARM 上编译 gst-plugins-bad 的另一个可能的资源是以下指南
您确定您的工具链有 libxml2 吗？或者更确切地说，你的系统根目录。
您可能需要导出 PKG_CONFIG，因此当您运行“pkg-config --libs libxml-2.0”时，您将获得正确的路径。另外，您可以检查生成的 Makefile 以查看使用的真正标志是什么，或者使用详细选项进行构建。
GStreamer 的构建内容也可能因交叉编译而被破坏，这是我使用 scrapbox 2 的原因之一；它使交叉编译变得透明。
