TI中文支持网我们自制板为了优化开机速度，把文件系统替换为arago-base-tisdk-image-am335x-evm.tar.xz。原来使用的是tisdk-rootfs-image-am335x-evm.tar.xz，一切正常。
使用build sdk中的方法，编译出的qt相关ipk文件。如：
qtbase_5.11.3+git0+08de243eaa-r0.arago16.tisdk5.7_armv7at2hf-neon.ipk
qtbase-dev_5.11.3+git0+08de243eaa-r0.arago16.tisdk5.7_armv7at2hf-neon.ipk
qtbase-mkspecs_5.11.3+git0+08de243eaa-r0.arago16.tisdk5.7_armv7at2hf-neon.ipk
qtbase-plugins_5.11.3+git0+08de243eaa-r0.arago16.tisdk5.7_armv7at2hf-neon.ipk
qtbase-tools_5.11.3+git0+08de243eaa-r0.arago16.tisdk5.7_armv7at2hf-neon.ipk
qtbase-staticdev_5.11.3+git0+08de243eaa-r0.arago16.tisdk5.7_armv7at2hf-neon.ipk
以上文件中tisdk-rootfs-image-am335x-evm.tar.xz安装时没有问题。在arago-base-tisdk-image-am335x-evm.tar.xz文件系统中安装出，报以下错误无法安装：

我尝试搜索完整系统中有关libfontconfig有关的东西，拷贝到arago-base-tisdk-image-am335x-evm.tar.xz文件系统对应目录，还是同样错误无法安装。如下：
在/usr/lib/下拷贝：libfontconfig.so，libfontconfig.so.1，libfontconfig.so.1.10.1
在/var/lib/opkg/info/下拷贝：libfontconfig1.list, libfontconfig1.control, libfontconfig-dev.list, libfontconfig1.postinst, libfontconfig-dev.control
请问，应该如何解决这个问题安装上QT5，是否有libfontconfig1相关的ipk供安装或如何控制编译。

使用SDK build的方法编译 fontconfig。 执行MACHINE=am335x-evm bitbake fontconfig后，报错如下：

Nancy Wang：
请问目前是编译到哪一步有问题？第一个问题解决了吗？我咨询一下相关工程师再给您回复。

user4894142：
主贴中的问题没解决。无法在arago-base-tisdk-image-am335x-evm文件系统中安装QT5.
回帖中的内容是我根据安装报错，猜测需要编译libfontconfig库，在yocto中编译出的错误。错误是在执行MACHINE=am335x-evm bitbake fontconfig后。像是编译脚本没有下载拷贝fontconfig源码
