Android NDK链接器(GStreamer)-无效的链接器名称-fuse-ld = gold [英] Android NDK Linker (GStreamer) - invalid linker name -fuse-ld=gold
问题描述
尝试在Windows上使用Android Studio设置Android的GStreamer.我主要是从他们的站点中最好地学习该教程我可以查看此(以及我认为有帮助的所有内容).我得到一个:
错误:错误:参数'-fuse-ld = gold'中的链接器名称无效
我的Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := app
LOCAL_SRC_FILES := app-1.c
LOCAL_SHARED_LIBRARIES := gstreamer_android
LOCAL_LDLIBS := -landroid
include $(BUILD_SHARED_LIBRARY)
ifndef GSTREAMER_ROOT
ifndef GSTREAMER_ROOT_ANDROID
$(error GSTREAMER_ROOT_ANDROID is not defined!)
endif
GSTREAMER_ROOT := $(GSTREAMER_ROOT_ANDROID)
endif
GSTREAMER_NDK_BUILD_PATH := $(GSTREAMER_ROOT)\share\gst-android\ndk-build
GSTREAMER_PLUGINS := coreelements ogg theora vorbis videoconvert audioconvert audioresample playback glimagesink soup opensles
G_IO_MODULES := gnutls
GSTREAMER_EXTRA_DEPS := gstreamer-video-1.0
include $(GSTREAMER_NDK_BUILD_PATH)\gstreamer-1.0.mk
和app/build.gradle:
apply plugin: 'com.android.application'

externalNativeBuild {
ndkBuild {

if (project.hasProperty('gstAndroidRoot'))
gstRoot = project.gstAndroidRoot
else
gstRoot = System.env.GSTREAMER_ROOT_ANDROID
if (gstRoot == null)
throw new GradleException('GSTREAMER_ROOT_ANDROID must be set, or "gstAndroidRoot" must be defined in your gradle.properties in the top level directory of the unpacked universal GStreamer Android binaries')

targets "app", "gstreamer_android"
// All archs except MIPS and MIPS64 are supported

}
}
}

}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
}
Gradle项目同步运行没有任何问题.但是Make Project会产生以下结果:
错误:错误:参数'-fuse-ld = gold'中的链接器名称无效
或更详细:

关于如何解决此问题的任何想法?我见过一些线程说要添加标志以使其成为gold.exe ...除非没有人说过设置标志的位置(而且线程似乎并没有太解决).
我按照gstreamer安装指南中的指示替换了"ld.exe"文件，即使该文件似乎已过时(我在遇到相同的错误后也这样做了-这样就不会造成它).
尝试将库链接在一起的clang.exe进程存在问题.请注意，无需按照问题链接中的安装说明更改ld.exe文件.
修复:您需要为每个体系结构在GStreamer目录中更改两个文件，以便链接程序被称为gold.exe而不是gold.
对于您感兴趣的每种体系结构，都需要转到(以arm64为例):
1)
path\to\Gstreamer\root\arm64\share\gst-android\ndk-build\gstreamer-1.0.mk并将-fuse-ld=gold更改为-fuse-ld=gold.exe(在文件中仅出现一次).
现在转到:
2)
path\to\Gstreamer\root\arm64\include\gmp.h并将-fuse-ld=gold更改为-fuse-ld=gold.exe(同样，仅出现一次).
对我发布的Android.mk和gradle文件进行了一些较小的修复，以使内容可以完全编译，但这似乎超出了此问题的范围(将-llog添加到本地ldlibs中，并且仅使用了核心插件). /p>
Trying to setup GStreamer for Android using Android Studio on Windows. I'm mostly following the tutorial from their site as best I can, as well as looking at this (plus whatever I can find that helps). I get an:

Gradle project sync runs without any problems. But Make Project produces the following:
Error:error: invalid linker name in argument '-fuse-ld=gold'
Or more verbose:

clang.exe: error: invalid linker name in argument '-fuse-ld=gold'
make: *** [buildsharedlibrary_arm64-v8a] Error 1
Any ideas on how to fix this? I've seen some threads that say to add flags to make it gold.exe...except no one is saying where the flags are set (and the threads didn't seem all too resolved).
I replaced the 'ld.exe' file as indicated in the gstreamer install guide, even if it seemed dated (I did that after getting the same error - so that's not causing it).
It is a problem with the clang.exe process that tries to link together the libraries. Note, there is no need to change the ld.exe file as in the install instructions from the link in the question.
Fix: you need to change two files per architecture in the GStreamer directory so that the linker gets called as gold.exe and not gold.
For each architecture you're interested in you need to go to (using arm64 as an example):
1)
path\to\Gstreamer\root\arm64\share\gst-android\ndk-build\gstreamer-1.0.mk and change -fuse-ld=gold to -fuse-ld=gold.exe (it only appears once in the file).
Now go to:
2)
path\to\Gstreamer\root\arm64\include\gmp.h and change -fuse-ld=gold to -fuse-ld=gold.exe (again, only one occurrence).
There were some minor fixes to my posted Android.mk and gradle files to get things to fully compile, but that seems outside the scope of this question (added -llog to local ldlibs and used only core plugin).
