Libtool 在 make install 期间未创建版本信息符号链接

【中文标题】Libtool 在 make install 期间未创建版本信息符号链接

【英文标题】：Libtool not creating version info symlinks during make install

【问题描述】：

在构建这个库时，我正在寻求有关 libtool 尴尬问题的帮助：http://github.com/mspanc/vspec

当我在我的 ubuntu 14.04 机器上构建它时，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。

但是，当我尝试使用来自 GStreamer 项目 (http://cgit.freedesktop.org/gstreamer/cerbero/) 的 Cerbero 构建系统进行交叉编译时，它基本上引导工具链进行交叉编译，在 make install 期间它只创建 .so 文件（没有 .so.VERSION_INFO 符号链接)，但仅适用于这个库，它可以成功地用于同一构建环境中的其他库。

显然，肯定有一些区别，但是我比较了 vspec 的 automakes 和其他已经安装了很长时间的项目，但仍然无法找出问题的根本原因。

我发现在运行./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 时生成的损坏库中的libtool 脚本具有version_type=none，而构建的脚本将此变量正确设置为linux。这种差异后来导致 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？

以下来自 Cerbero 的 make install 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 cmets。版本库 will not be added 到 Android。
