Question

我在构建此库时寻求libtool难题的帮助：http://github.com/mspanc/vspec

当我在我的ubuntu 14.04盒子上构建它时，它工作正常，在make install期间添加它会创建适当的.so.VERSION_INFO符号链接。

然而，当我尝试使用来自GStreamer项目（http://cgit.freedesktop.org/gstreamer/cerbero/）的Cerbero构建系统交叉编译它时，它基本上引导了用于交叉编译的工具链，在make install期间它只创建.so文件（没有.so。 VERSION_INFO符号链接），但仅适用于此库，它使同一构建环境中的其他库成功。

显然，肯定会有一些区别，但我认为vspec和其他项目的自动化程序已经安装好了很长时间，但仍然无法弄清问题的根本原因。

我发现在运行libtool时生成的已损坏库中的./configure --prefix /root/cerbero/dist/android_armv7 --libdir /root/cerbero/dist/android_armv7/lib --disable-maintainer-mode --disable-silent-rules --disable-introspection --host=arm-linux-androideabi脚本具有version_type=none，而构建的脚本已将此变量正确设置为linux。之后的差异导致libtool不添加符号链接。

这里的任何人都可以给我任何提示，在生成libtool时，我应该在哪里寻找导致无效主机识别的原因？

来自Cerbero的make install的日志：

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

对于Android，这是该平台的预期libtool输出。请参阅this libtool patch上的评论。版本化的库will not be added到Android。

Libtool在make install
