在使用ndk为android编译live555时,我遇到了这个错误!
cd liveMedia ; make

错误说明:
arm-linux-androideabi-ar: -L/home/jomit/Applications/android-ndk-r6/sources/cxx-stl/gnu-libstdc++/libs/armeabi: No such file or directory
但我的文件系统上有/home/jomit/Applications/android-ndk-r6/sources/cxx-stl/gnu-libstdc++/libs/armeabi
目录。它是通过从android ndk的make-standalone-toolchain.sh
目录运行脚本tools
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/
为ndk及其子目录授予了所有权限。我的问题是如何解决这个错误?
注意:
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。
以下是我正在运行以编译live555的android.sh
文件:
#!/bin/sh

这两个文件 - android.sh

- 都是端口已有的文件。
我非常感谢任何帮助,因为Google对这个问题缺乏了解:)
答案 0 :(得分:0)
问题是GNU ar (在这种情况下是arm-linux-androideabi-ar)不接受-L选项,这导致它将其视为文件(而不是路径)动态链接时应该转到 gcc / ld 的选项。
ar 从一组目标文件中编译静态库,因此不需要/遵守 -L 选项。
