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 相关的头文件、库和文件都放在我的 sysroot 中。

当我配置everyrhing 似乎没问题，但尝试编译结果：

似乎它正试图链接到我的桌面 libxml2。为什么它不链接到我的工具链中包含所有符号的那个？

你确定你的工具链有 libxml2 吗？或者更确切地说，你的 sysroot。

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。此外，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 的构建内容也有可能因交叉编译而损坏，这也是我使用 Scratchbox 2 的原因之一；它使交叉编译透明。

您的配置脚本是否支持 autoconf 交叉编译？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 是否设置为使用您的交叉编译器？

要设置这些，您可以在手册中覆盖它们或使用环境变量，如下例所示

export CC=arch-gcc export CXX=arch-c++ export arch-ld export AR=arch-ar export AS=arch-as export NM=arch-nm export STRIP=arch-strip

如果设置为yes，则检查makefile 中专门针对libxml 的包含路径。

在 ARM 上编译 gst-plugins-bad 的另一个可能资源是以下指南
