参考https://whycan.cn/t_1352.html
进入到buildroot根目录下 通过vim .config修改.config文件,文件开头添加
BR2_PACKAGE_CAIRO=y
BR2_PACKAGE_PIXMAN=y
但是在编译根文件系统是出现编译错误
zhang@zhang-virtual-machine:~/buildroot-2017.08.1$ make
Makefile:539: *** fontconfig is in the dependency chain of cairo that has added it to its _DEPENDENCIES variable without selecting it or depending on it from Config.in。 停止。
Makefile:79: recipe for target '_all' failed
make: *** [_all] Error 2

打包部分 lib 文件:
cd /disk4/buildroot-2017.08.1/output/host/arm-buildroot-linux-gnueabi/sysroot
tar cvf /mnt/hgfs/E/libcairo.tar ./usr/lib/libcairo* ./usr/lib/engines/lib* ./usr/lib/libpixman-1.* ./usr/lib/libfontconfig.* ./usr/lib/libexpat.* ./usr/lib/libfreetype.* ./usr/lib/libatomic.*
我在进行打包是出现文件缺失,会有影响?

普通用户不能访问设备文件, 你加 sudo 就不会有这个错误了。
我在打包的时候已经加了sudo了,错误应该是./usr/lib文件下没有engines文件夹和缺失前缀为libatomic.的文件,这样的原因会是buildroot编译错误?

有可能,找一台配置高、干净的电脑重新来一次.
看起来是软连接指向的文件挂了。
.....重新在buildroot根目录下make一次可以?换电脑这个没办法...

buildroot 的 .config 文件
我在别人博客上看到make menuconfig后
Target packages --->
Graphic libraries and applications (graphic/text) --->
Qt5 --->
Enable Tslib support
我下的根文件系统不一样..我在QT5下没有tslib选项,应该在哪里勾上tslib?
