为Android编译时没有此类文件或目录错误

Question

在使用ndk为Android编译live555时，我陷入了这个错误！

cd liveMedia ; make
make[1]: Entering directory `/home/jomit/Public/jimjh-liveMedia-for-Android-0c18fdd/liveMedia'

错误状态：

arm-linux-androideabi-ar: -L/home/jomit/Applications/android-ndk-r6/sources/cxx-stl/gnu-libstdc++/libs/armeabi: No such file or directory

但是我的文件系统上确实有目录/home/jomit/Applications/android-ndk-r6/sources/cxx-stl/gnu-libstdc++/libs/armeabi 。 它是通过从android ndk的tools目录运行脚本make-standalone-toolchain.sh获得的。 为了避免所有权限问题，我使用chmod 777 -R /home/jomit/Applications/android-ndk-r6/授予了ndk及其子目录的所有权限。 我的问题是如何解决此错误？

笔记：

来自github的liveMedia-for-Android是我正在使用的live555 android端口。

我正在运行64位Fedora 16。

以下是我正在运行的live555的android.sh文件：

#!/bin/sh
# 
# Builds libraries for Android
# Written by Jiunn Haur Lim <jim@jh-lim.com>

export PATH="${NDK_ROOT}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/:${PATH}"

SYS_ROOT="${NDK_ROOT}/platforms/android-8/arch-arm"

export LD="${PREF}ld  --sysroot=${SYS_ROOT}"

./genMakefiles android
make

以下是config.android文件：

CONSOLE_LINK_OPTS =     $(LINK_OPTS)

LIBRARY_LINK    =       $(CROSS_COMPILE)ar cr 

LIBRARY_LINK_OPTS =     $(LINK_OPTS)

LIB_SUFFIX      =           a

LIBS_FOR_CONSOLE_APPLICATION =

LIBS_FOR_GUI_APPLICATION =

这两个文件android.sh和config.android都是端口已经可用的文件。

我非常感谢您的帮助，因为Google对此问题有点了解：)

Answer 1

(arm-linux-androideabi-ar in this case) does not accept the -L option, which causes it to treat that as a file (rather than a path option that should go to gcc/ld while dynamic linking). 问题是GNU （在这种情况下为arm-linux-androideabi-ar）不接受-L选项，这导致它将其视为文件（而不是动态时应转到gcc / ld的路径选项）链接）。

option. ar从一组目标文件编译一个静态库，因此不需要/使用选项。
