如何构建没有版本后缀的ffmpeg共享库 [英] how to build ffmpeg shared libraries without version suffix

问题描述

有没有一种我可以配置构建ffmpeg的共享库的Android，没有版本号后缀？我可以使用不同的选项构建，但总是得到像libavcodec.so.57这样的文件。我需要没有后缀的库，如libavcodec.so。我认为选项--disable-symver会做这个伎俩，但遗憾的是没有。问题是我有一个库（.so文件），依赖于没有后缀的ffmpeg共享库，因此无法加载这些im。
i主要遵循此处的说明

解决方案

提问有助于永远找到答案。这就是为什么我是成功的，挖掘文件帮助。执行以下操作：

• 运行您的配置


• 找到config.mak



• 更改

  
  
  

  SLIBNAME_WITH_VERSION = $（SLIBNAME）$（LIBVERSION）
  SLIBNAME_WITH_MAJOR = $（SLIBNAME） LIBMAJOR）

  
  
  

  to：

  
  
  

  SLIBNAME_WITH_VERSION = $（SLIBNAME）
  
  SLIBNAME_WITH_MAJOR = $ （SLIBNAME）




• 更改

  
  
  

  SLIB_INSTALL_NAME = $（SLIBNAME_WITH_VERSION）
  SLIB_INSTALL_LINKS = $ （SLIBNAME_WITH_MAJOR）$（SLIBNAME）

  
  
  

  至：

  
  
  

  SLIB_INSTALL_NAME = $（SLIBNAME）
  
  SLIB_INSTALL_LINKS =




• 运行make或make -j $（nproc）




• make install

现在，您将拥有没有后缀的共享库。

你可以检查它们的依赖项
readelf -d somefile.so

is there a way i can configure to build ffmpeg shared libraries for android without version number suffixes? im able to build with different options but always get files like "libavcodec.so.57". i would need the libraries without suffixes like "libavcodec.so". i thought the option "--disable-symver" would do the trick but unfortunately it didn't. the problem is that i have a library (.so file) that depends on ffmpeg shared libraries without suffixes and therefore can't load those im getting built. i have followed mostly the instructions here.

解决方案

asking questions leads always to finding answers. that's why i was successful, digging into the make files helped. do the following:

• run your configuration
• find "config.mak"

• change

  SLIBNAME_WITH_VERSION=$(SLIBNAME).$(LIBVERSION) SLIBNAME_WITH_MAJOR=$(SLIBNAME).$(LIBMAJOR)

  to:

  SLIBNAME_WITH_VERSION=$(SLIBNAME)
  SLIBNAME_WITH_MAJOR=$(SLIBNAME)

• change

  SLIB_INSTALL_NAME=$(SLIBNAME_WITH_VERSION) SLIB_INSTALL_LINKS=$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)

  to:

  SLIB_INSTALL_NAME=$(SLIBNAME)
  SLIB_INSTALL_LINKS=

• run "make" or "make -j$(nproc)"

• "make install"

now you will have shared libraries without suffixes.
you can check their dependencies by "readelf -d somefile.so"
