E/HAL     (  307): load: module=/system/lib/hw/gps.default.so
E/HAL     (  307): dlopen failed: could not load library "libandroid_runtime.so" needed by "gps.default.so"; caused by library "libandroid_runtime.so" not found

probably related to bug 1021559.

Comment 2

[Doug Turner (:dougt)]

This needs to be figured out or the gps hw will not work.

I find that b2g/device/t2m/flame/extract-files.sh doesn't extract libandroid_runtime.so, however, it is included in the base image.

% readelf -d gps.default.so

We probably need to add libandroid_runtime.so to extract-files.sh or remove the dependency of it from gps.default.so

This bug probably only affects SPRD Dolphin devices. We don't need to uplift this fix to 2.0 if SPRD doesn't plan to ship any devices based on 2.0.

Comment 5

[Chris Peterson [:cpeterson]]

Kan-Ru: are you looking into this bug? Is the Dolphin device's hardware GPS currently working in SPRD's builds?

I know that first Dolphin launch will have hardware GPS disabled, but subsequent Dolphin launches will have hardware GPS enabled.

I'm not looking into this bug. This seems more like a porting issue. We have to decide whether to pull in libandroid_runtime.so for Dolphin and Flame and maybe future devices.

Michael, what do think?

Comment 7

[Michael Wu [:mwu]]

My gps.default.so loads fine. Not getting a lock, but it does start the GPS HAL module.

Comment 8

[Michael Wu [:mwu]]

Also, fwiw, libandroid_runtime.so is not an acceptable library for extract-files.sh.

Comment 9

[Michael Wu [:mwu]]

You might want to try updating your vendor/sprd/gps to the latest - the v1.4 branch manifest locks it to an older version.

Comment 10

[Chris Peterson [:cpeterson]]

Garvan: are you able to reproduce this error (assuming you can now build and install 1.4 for your Dolphin)? dougt reported this problem with his build, so this might be a local problem for him.

Comment 11

[:garvan]

reboot device
adb logcat | grep gps

I don't see this. Of course, I don't get gps either, so I wouldn't trust what I am seeing as being useful for this bug report.

I flashed a highly build for this, I can't build: https://bugzilla.mozilla.org/show_bug.cgi?id=1033421

Comment 12

[Kai-Chih Hu [:khu]]

Looks like no one else has this issue. Dougt, would you mind trying this again? If this is a local problem in your environment, we may need to close this bug. What do you think? Thanks!
