d1s和d1哪吒跑QT4.8.7不起来，有一回在D1S上起来了，但文件系统被我刷了，现在就是要么报OOM要么就是报环境问题

使能了这句就会出现这样的现象。就跑成功过一次，还没记录。
现在在mq上和哪吒上都不行了。
不过qt5是可以起来的。

qt4.8.7.tar
编译出来的如上。 -
内存不足？可以停了adb，回收一下内存再跑echo 3 > /proc/sys/vm/drop_caches
期待 d1s能跑起来，到时白嫖一下环境。哈哈 -
@soso90 不是内存不足，我在d1s上也跑过，就成功了一次，然后环境被我刷了，后面就再也没起来过，理论上哪吒d1不会内存不够的，QT5都能起来的，就是qt4不行，怀疑过文件系统问题，但显示能跑起来的也被我格式化了
-
我的 Qt5 @ D1s 也挂了：

上 LVGL吧， Qt跑不起来，占用内存太多了。
