错误而编译库ARM平台

Question

我用我的工具链编译GST-插件坏了ARM。我编译了构建它所需的所有东西，包括gstreamer，libmms等等，并将它们放在我的sysroot中，包括与pkg-config相关的头文件，库和文件。

当我配置everyrhing似乎确定，但试图编译结果：

看来它正试图对我的桌面libxml2的链接。为什么它不链接到我拥有所有符号的工具链中的链接？

Answer 1

请问您的配置脚本支持autoconf的交叉编译？ 在configure.in，什么是shell变量cross_compiling的调用AC_PROG_CC后的价值？

如果它被设置为无，则生成文件设置为使用您的交叉编译器？

要设置这些既可以覆盖它们在手册中或使用环境变量等 下面

出口CC =拱GCC 出口CXX =拱-C++ 出口拱-LD 出口AR的示例=拱-AR 出口AS =拱作为 出口NM =拱纳米 出口STRIP =拱条

如果它被设置为是，则检查包括路径专门为在生成文件的libxml。

你确定你的工具链有libxml2的？或者说，你的系统。

您可能需要导出PKG_CONFIG，所以当你运行“pkg配置的libxml --libs-2.0”你在正确的道路。另外，您可以检查生成的Makefile以查看使用的真正标志，或使用详细选项构建。

GStreamer的构建内容也可能因为交叉编译而被破坏，这也是我使用scratchbox 2的原因之一;它使交叉编译透明。
