AOSP L build - screenrecord - CANNOT LINK EXECUTABLE

Question

I needed screenrecord application in android L to record longer videos. I followed advice from this question and decided to build android. How to increase time limit of ADB screen record of Android Kitkat

After many attempts I haven't succeded, because screenrecorder binary extracted from build doesn't work. When I push screenrecord file to ANDROID and after chmod and starting screenrecord this is communicate I'm getting:

CANNOT LINK EXECUTABLE: empty/missing DT_HASH in "./screenrecord" (built with --hash-style=gnu?)

I am using Ubuntu 14 and lunch configuration hammerhead as I am testing this on Nexus 5.

How can i fix it?

Answer 1

一种选择是在屏幕记录Android.mk上添加“ LOCAL_LDFLAGS：= -Wl，-hash-style = sysv”，尽管我确信这样做的方法不那么简单。

Answer 2

I don't know the limit for Android L, but 180 seconds is the max limit for KitKat, I run multi time ( 3min each) and combine it together.
