GStreamer 链接错误

Question

I'm trying to build the source code of https://github.com/iiordanov/remote-desktop-clients/tree/master/eclipse_projects/Opaque .

Now there's an error while building the gstreamer library:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:externalNativeBuildDebug'.
> Build command failed.

I also tried to rename the linker to "gold.exe", but it doesn't change anything I'm currently using the ARM Build of GStreamer Version 1.9.2 https://gstreamer.freedesktop.org/data/pkg/android/1.9.2/

So does anybody know how to solve this error?

Answer 1

Looks like gstreamer unconditionally passes -fuse-ld=gold :

$ grep -rI fuse-ld .
...
./share/gst-android/ndk-build/gstreamer-1.0.mk:GSTREAMER_LD                  := -fuse-ld=gold -Wl,-soname,lib$(GSTREAMER_ANDROID_MODULE_NAME).so

The NDK doesn't ship ld.gold for mips/mips64. You need to gate -fuse-ld=gold use against TARGET_ARCH like so:

# mips/mips64 don't have ld.gold.
ifeq (,$(filter mips mips64,$(TARGET_ARCH)))
    LOCAL_LDFLAGS += -fuse-ld=gold
endif

Alternatively, just don't pass -fuse-ld=gold . The NDK will default to it for the other architectures (aside from aarch64, where bfd is still the default).

Answer 2

Precompiled gstreamer binaries does not include mips support yet. You should exclude mips from build..
